Bathing in Hydrogen Water: The Secret to Youthful, Elastic, and Glowing Skin (2024) 77
Tumblr media
What is Hydrogen Water?
Hydrogen water is simply water infused with molecular hydrogen (H2). Unlike regular water, which contains two hydrogen atoms bonded to one oxygen atom (H2O), hydrogen water has additional free hydrogen molecules. These extra hydrogen molecules are believed to offer powerful antioxidative properties, which can neutralize harmful free radicals in the body.
The Science Behind Hydrogen Water and Skincare
Several studies have explored the potential benefits of hydrogen-rich water. One study published in the Journal of Photochemistry and Photobiology found that hydrogen water can significantly reduce skin damage caused by UV radiation, owing to its potent antioxidative properties (Fukuda et al., 2011). Another study demonstrated that hydrogen water could improve skin conditions such as wrinkles and pigmentation by reducing oxidative stress (Matsumoto et al., 2012).
These findings suggest that hydrogen water’s antioxidative properties help combat the primary causes of skin aging: oxidative stress and inflammation. When applied topically through a bath, hydrogen water can penetrate deep into the skin layers, providing hydration and promoting cell repair and regeneration.
Benefits of Hydrogen Water Baths
1. Antioxidation and Anti-Aging
Hydrogen gas has strong permeability, allowing it to quickly penetrate the body through the skin during a hydrogen water bath. This direct contact with the skin enables hydrogen to act on human cells, neutralizing free radicals that cause oxidative stress. The result? Reduced wrinkles, improved skin elasticity, and enhanced skin lubricity.
2. Skin Tightening and Elasticity Enhancement
Regular hydrogen water baths can significantly tighten the skin and enhance its elasticity, helping maintain a youthful appearance. The hydrogen molecules promote collagen production, a vital protein for skin firmness and elasticity.
3. Acne and Pigmentation Reduction
Hydrogen water’s anti-inflammatory properties can help reduce acne and lighten pigmentation such as freckles and age spots. This makes hydrogen baths an effective solution for achieving an even skin tone and clearer complexion.
4. Improvement of Skin Conditions
Continuous use of hydrogen water baths has shown improvement in various skin conditions, including dermatitis, eczema, hives, and psoriasis. Users often notice significant relief within the first week of daily use.
5. Joint and Bone Health
Beyond skincare, hydrogen gas can penetrate human bone joints and bones, providing relief from arthritis, rheumatism, gout, and other joint-related ailments. This makes hydrogen baths beneficial for overall musculoskeletal health.
6. Enhanced Relaxation and Sleep Quality
Hydrogen water baths promote overall relaxation, effectively relieving fatigue and improving sleep quality. This can be particularly beneficial for those suffering from insomnia or stress-related sleep disorders.

Jason Wargent: Founder of ‘BioLumic’ – A Technology to increase crop productivity.
The using of technology and science in the field of agriculture is not new there are already several inventions done and are effectively been used by farmers to increase their yield and profitability. Agriculture contributes majorly to the global economy and for most of the countries in Asia, it provides large employment and a source of income. Agriculture has a vital role in promoting economic growth, environmental sustainability, and the food system. In New Zealand agriculture, fishery, and forestry are high in production and export. The farming sector includes dairy, meat products, and horticulture, in the year 2023 the GDP (gross domestic product) generated from this industry was around 13.9 billion New Zealand dollars.
Tumblr media
The largest production of the country is Kiwi fruit which is exported highly and brings more value to the Horticulture sector. The main issue faced in raising crops is the changing climatic condition which reduces the proper growth of plants and hence leads to loss and less productivity. In this article, we are discussing an innovative technology that helps in crop production and a biotech company founded by Jason Wargent called BioLumic. This is used to program plants with light to improve their growth and reduce disease.
Dr. Jason Wargent: Founder & CSO
Jason Wargent is the founder and Chief Science Officer of an agri-tech startup company called BioLumic which was founded in the year 2012. He is the world-leading plant UV photobiologist and has done more than 15 research. He obtained a Doctor of Philosophy (PhD) in the studies of Plant Physiology from Lancaster University. During his PhD course, Jason took part in a program that delivered fundamental scientific and tech-transfer insights for the application of UV photobiology for agronomic gains. He worked as an Associate professor at Massey University, for one of the world’s top 25 agri-science Universities. later he was an entrepreneur in Residence and Professor. As he was more into plants and the agriculture sector he started his experiments by applying the technique of programming plants with light.
About BioLumic
BioLumic is an agriculture company which is located at Palmerston North, that makes use of science and technology to increase the yield along with the profitability of the framer. BioLumic UV-based technology is used to deliver ultraviolet light rays to seeds to trigger the mechanism that is helpful in the growth of the plant this also improves the plant’s performance. The science behind it is to control the seed to gain sustainable grains, seeds have their known growth mechanism and a generic composition where these genes transduce UV signals and regulate the downstream technology. With the help of BioLumic technology, we can introduce the targeted application into a seed before growing it which benefits the crop productivity. 
Different combinations of the UV recipes are created and tested by sowing them, which gives the exact winning combination of the seed. In many cases, fruits and vegetables are initially grown at the nursery and are later transferred to the field or other farmland for harvesting but at BioLumic they apply UV light technology to seedlings that unlock the potential of the plant. Along with the nutritional value the major thigh is the sustainability of crops in different climatic conditions that might occur and also the resistance and tolerance to diseases. BioLumic helps strengthen the roots of crops by the alteration of root architecture and their manipulation of UV morphogenesis will result in an increase of biomass to roots. All these will help in increasing plant nutrients and hence the growth of crops.
They have effective results and growth with crops like cannabis, row crops, and strawberries. Seeds of the cannabis plant are full of untapped genetic potential with which the one-time application of UV light treatment will provide the optimized physical and chemical properties that result in the best growth and yield of these plants. This is also more effective in boosting the growth of strawberries with applied at the young stage. BioLumic with the use of the Light Signal Recipe Platform for different combination-making will provide the best treatment that does not need any chemical application which will also result in the growth and high yield of crops and hence, increase profitability.

The effect of LED supplementary light on the growth of horticultural crops
Tumblr media
The types of facilities in facility horticulture mainly include plastic greenhouses, sunlight greenhouses, multi story greenhouses, and plant factories. Due to the fact that facility buildings block natural light sources to a certain extent, indoor lighting is insufficient, resulting in reduced crop yield and quality. Therefore, fill lights play an indispensable role in the high-quality and high-yield of facility crops, but also become the main factor in increasing energy consumption and operating costs within the facility.
For a long time, artificial light sources used in the field of facility horticulture mainly include high-pressure sodium lamps, fluorescent lamps, metal halide lamps, incandescent lamps, etc. The prominent disadvantages are high heat production, high energy consumption, and high operating costs. The development of the new generation of Light Emitting Diodes (LEDs) has made it possible to apply low energy artificial light sources in the field of facility horticulture.
LED has advantages such as high photoelectric conversion efficiency, use of direct current, small size, long lifespan, low energy consumption, fixed wavelength, low thermal radiation, and environmental protection. Compared with commonly used high-pressure sodium lamps and fluorescent lamps, LED not only allows for precise adjustment of light quantity and quality (such as the proportion of light in various bands) according to the needs of plant growth, but also allows for close illumination of plants due to its cold light properties, thereby increasing the number of cultivation layers and space utilization, achieving energy-saving, environmental protection, and efficient space utilization functions that traditional light sources cannot replace.
Based on these advantages, LED has been successfully applied in facility horticultural lighting, basic research on controllable environments, plant tissue culture, factory seedling cultivation, and aerospace ecosystems. In recent years, the performance of LED grow lights has been continuously improving, their prices have gradually decreased, and various specific wavelength products have been gradually developed. Their application scope in agriculture and biology will be even broader.
This article reviews the current research status of LED in the field of facility horticulture, with a focus on the photobiological basis of LED supplementary lighting applications, the impact of LED supplementary lighting on plant photomorphogenesis, nutritional quality and anti-aging, the construction and application of light formulas, and other aspects. It also analyzes and looks forward to the current problems and prospects of LED supplementary lighting technology.
The effect of LED supplementary light on the growth of horticultural crops
The regulatory effects of light on plant growth and development include seed germination, stem elongation, leaf and root development, phototropism, chlorophyll synthesis and decomposition, and flower induction. The lighting environment elements inside the facility include light intensity, light cycle, and spectral distribution. By manually supplementing light, their elements can be adjusted without being limited by weather conditions.
Plants have the characteristic of selective absorption of light, and different light receptors perceive light signals. Currently, it has been found that there are at least three types of light receptors in plants: photosensitizers (absorbing red and far red light), cryptocyanins (absorbing blue and near ultraviolet light), and ultraviolet light receptors (UV-A and UV-B). Using a specific wavelength light source to illuminate crops can improve the photosynthetic efficiency of plants, accelerate their light morphogenesis, and promote their growth and development.
Plant photosynthesis mainly utilizes red orange light (610-720 nm) and blue purple light (400-510 nm). By utilizing LED technology, monochromatic light (such as red light with a peak of 660nm and blue light with a peak of 450nm) that conforms to the strongest absorption band of chlorophyll can be emitted, with a spectral domain width of only ± 20 nm.
At present, it is believed that red orange light can significantly accelerate plant development, promote the accumulation of dry matter, form bulbs, tubers, leaf bulbs, and other plant organs, cause plants to bloom and bear fruit earlier, and play a dominant role in plant coloration; Blue and purple light can control the phototropism of plant leaves, promote stomatal opening and chloroplast movement, inhibit stem elongation, prevent plant overgrowth, delay plant flowering, and promote the growth of nutrient organs; The combination of red and blue LED can compensate for the deficiency of monochromatic light in both, forming a spectral absorption peak that is basically consistent with crop photosynthesis and morphology. The light energy utilization rate can reach 80%~90%, and the energy-saving effect is significant.
Equipping LED supplementary lights in facility horticulture can achieve significant yield increase effects. Studies have shown that 300 μ The number of fruits, total yield, and single fruit weight of cherry tomatoes under 12 hours (8:00-20:00) of supplementary lighting with mol/(m? · s) LED strips and LED tubes were significantly increased. The supplementary lighting with LED strips increased by 42.67%, 66.89%, and 16.97%, respectively, while the supplementary lighting with LED tubes increased by 48.91%, 94.86%, and 30.86%, respectively. Full growth period LED light replenishment [red blue light quality ratio of 3:2, light intensity of 300] μ The treatment of mol/(m? · s) significantly increased the single fruit weight and unit area yield of Jiegua and eggplant, with Jiegua increasing by 5.3% and 15.6%, and eggplant increasing by 7.6% and 7.8%. By adjusting the temporal and spatial distribution of LED light quality, intensity, and duration throughout the entire growth period, it is possible to shorten the plant growth cycle, improve the commercial yield, nutritional quality, and morphological value of agricultural products, and achieve efficient, energy-saving, and intelligent production of horticultural crops in facilities.
Application of LED supplementary light in vegetable seedling cultivation
LED light source regulation of plant morphogenesis and growth and development is an important technology in the field of greenhouse cultivation. Higher plants can sense and receive light signals through photoreceptor systems such as photosensitive pigments, cryptocyanins, and phototropins, and regulate morphological changes in plant tissues and organs through intracellular messenger transduction. Photomorphogenesis is the process in which plants rely on light to control cell differentiation, structural and functional changes, as well as tissue and organ development. This includes effects on partial seed germination, promotion of apical dominance to inhibit lateral bud growth, stem elongation, and induction of meridional movement.
Vegetable seedling cultivation is an important part of facility agriculture. Continuous cloudy and rainy weather can lead to insufficient lighting in the facilities, making seedlings prone to elongation, which in turn affects the growth, flower bud differentiation, and fruit development of vegetables, ultimately affecting their yield and quality. In production, some plant growth regulators such as gibberellin, auxin, paclobutrazol, and chloramphenicol are used to regulate the growth of seedlings. However, the unreasonable use of plant growth regulators can easily pollute vegetables and facility environments, which is detrimental to human health.
LED supplementary lighting has many unique advantages in supplementary lighting, and the application of LED supplementary lighting in seedling cultivation is a feasible approach.
In low light [0-35] μ LED replenishment under the condition of mol/(m? · s) [25 ± 5] μ In the mol/(m? · s) experiment, it was found that green light promoted the elongation and growth of cucumber seedlings, while red and blue light inhibited seedling elongation. Compared with natural weak light, the strong seedling index of seedlings supplemented with red and blue light increased by 151.26% and 237.98%, respectively. Moreover, compared with monochromatic light, the strong seedling index of cucumber seedlings treated with composite light containing red and blue components increased by 304.46%. Supplementing cucumber seedlings with red light can increase their true leaf number, leaf area, plant height, stem thickness, dry and fresh weight, seedling strength index, root vitality, SOD activity, and soluble protein content. Supplementing with UV-B can increase the chlorophyll a, chlorophyll b, and carotenoid content in cucumber seedling leaves; Compared with natural light, supplementing LED red and blue light significantly increased the leaf area, dry matter quality, and seedling strength index of tomato seedlings. Supplementing LED red and green light significantly increased the height and stem thickness of tomato seedlings; LED green light supplementation treatment can significantly increase the biomass of cucumber and tomato seedlings, and the fresh and dry weight of young seedlings show an increasing trend with the increase of green light supplementation intensity. However, the stem diameter and strong seedling index of tomato seedlings increase with the increase of green light supplementation intensity; The combination of LED red and blue light can increase the stem thickness, leaf area, whole plant dry weight, root to shoot ratio, and seedling strength index of eggplants; Compared with white light, LED red light can increase the biomass of cabbage seedlings, promote the elongation growth and leaf expansion of cabbage seedlings; LED blue light promotes the thickening growth, dry matter accumulation, and seedling strength index of cabbage seedlings, leading to dwarfing of cabbage seedlings. The above results indicate that vegetable seedlings cultivated by combining light regulation technology have significant advantages.
The influence of LED supplementary light on the nutritional quality of fruits and vegetables
The protein, sugars, organic acids, and vitamins contained in fruits and vegetables are beneficial nutrients for human health. Light quality can affect the content of VC in plants by regulating the activity of VC synthesis and decomposition enzymes, and has a regulatory effect on protein metabolism and carbohydrate accumulation in horticultural plants. Red light promotes carbohydrate accumulation, while blue light treatment is beneficial for protein formation. The combination of red and blue light significantly improves the nutritional quality of plants compared to monochromatic light. Supplementing LED red or blue light can reduce the nitrate content in lettuce, supplementing blue or green light can promote the accumulation of soluble sugars in lettuce, and supplementing infrared light is beneficial for the accumulation of VC in lettuce. Supplementing with blue light can promote the increase of VC content and soluble protein content in tomatoes; The combination of red light and red blue light treatment promotes the sugar and acid content in tomato fruits, and the sugar to acid ratio is highest under the combination of red and blue light treatment; The combination of red and blue light can promote the increase of VC content in cucumber fruits.
The phenolic substances, flavonoids, anthocyanins and other substances contained in fruits and vegetables not only have a significant impact on the color, flavor, and commercial value of fruits and vegetables, but also have natural antioxidant activity, which can effectively inhibit or eliminate free radicals in the human body. The use of LED blue light supplementation can significantly increase the content of anthocyanins in eggplant peel by 73.6%, while the use of LED red light and red blue combination light can increase the content of flavonoids and total phenols; Blue light can promote the accumulation of lycopene, flavonoids, and anthocyanins in tomato fruits. The combination of red and blue light can promote the generation of anthocyanins to a certain extent, but inhibit the synthesis of flavonoids; Compared with white light treatment, red light treatment can significantly increase the anthocyanin content in lettuce aboveground parts, but blue light treatment has the lowest anthocyanin content in lettuce aboveground parts; The total phenolic content of green leaf, purple leaf, and red leaf lettuce was higher under white light, red blue combined light, and blue light treatments, but it was the lowest under red light treatment; Supplementing LED ultraviolet or orange light can increase the content of phenolic compounds in lettuce leaves, while supplementing green light can increase the content of anthocyanins. Therefore, using LED supplementary lighting is an effective way to regulate the nutritional quality of fruits and vegetables in facilities.
The effect of LED fill light on delaying plant aging
The degradation of chlorophyll, rapid loss of protein, and RNA hydrolysis during plant aging are mainly manifested as leaf aging. Chloroplasts are highly sensitive to changes in the external light environment, especially significantly influenced by light quality. Red light, blue light, and a combination of red and blue light are beneficial for the morphogenesis of chloroplasts. Blue light is beneficial for the accumulation of starch granules in chloroplasts, while red and far red light have negative effects on chloroplast development. Blue light and the combination of red and blue light can promote the synthesis of chlorophyll in cucumber seedling leaves, while the combination of red and blue light can also delay the decline of chlorophyll content in the later stage. This effect becomes more pronounced with the decrease of red light ratio and the increase of blue light ratio. The chlorophyll content of cucumber seedling leaves under LED red and blue combined light treatment was significantly higher than that under fluorescent light control and monochromatic red and blue light treatment; LED blue light can significantly increase the chlorophyll a/b values of Wutai vegetable and green garlic seedlings.
Changes in content of cytokinin (CTK), auxin (IAA), abscisic acid (ABA), and various enzyme activities occur during leaf senescence. The content of plant hormones is easily influenced by the light environment, and different light qualities have different regulatory effects on plant hormones. The initial steps of the light signal transduction pathway involve cytokinins. CTK promotes leaf cell expansion, enhances leaf photosynthesis, and inhibits the activities of ribonuclease, deoxyribonuclease, and protease, delaying the degradation of nucleic acid, protein, and chlorophyll, thus significantly delaying leaf aging. There is an interaction between light and CTK mediated developmental regulation, where light can stimulate an increase in endogenous cytokinin levels. When plant tissues are in an aging state, their endogenous cytokinin content decreases. IAA is mainly concentrated in areas with vigorous growth, and its content is minimal in aging tissues or organs. Purple light can enhance the activity of indole-3-acetic acid oxidase, while low levels of IAA can inhibit plant elongation and growth. ABA is mainly formed in aging leaf tissue, mature fruits, seeds, stems, roots and other parts. Under red blue combined light, the ABA content in cucumber and cabbage is lower than that under white and blue light.
Peroxidase (POD), superoxide dismutase (SOD), ascorbic acid peroxidase (APX), and catalase (CAT) are important and light related protective enzymes in plants. If plants age, the activity of these enzymes will rapidly decrease. The effect of different light qualities on plant antioxidant enzyme activity is significant. After 9 days of red light treatment, the APX activity of rapeseed seedlings significantly increases, while the POD activity decreases; After 15 days of red and blue light irradiation, the POD activity of tomatoes was 20.9% and 11.7% higher than that of white light, respectively. After 20 days of green light treatment, the POD activity was the lowest, only 55.4% of that of white light; Supplementing with 4 hours of blue light can significantly increase the soluble protein content, POD, SOD, APX, and CAT enzyme activity in cucumber seedling leaves. In addition, the activities of SOD and APX gradually decrease with the prolongation of light exposure time. The activities of SOD and APX under blue and red light irradiation decreased slowly but remained higher than those under white light. Red light irradiation significantly reduced the peroxidase and IAA peroxidase activities in tomato leaves and eggplant leaves, but caused a significant increase in the peroxidase activity in eggplant leaves. Therefore, adopting a reasonable LED lighting strategy can effectively delay the aging of horticultural crops in facilities, improve yield and quality.
Construction and application of LED light formula
The growth and development of plants are significantly influenced by light quality and its different composition ratios. The light formula mainly includes several elements such as light quality ratio, light intensity, and light duration. Due to the differences in light requirements among different plants and their varying growth and development stages, it is necessary to optimize the combination of light quality, intensity, and replenishment time for the cultivated crops.
Light quality ratio
Compared with white light and single red and blue light, the combination of LED red and blue light shows a comprehensive advantage in the growth and development of cucumber and cabbage seedlings. When the ratio of red and blue light is 8:2, the stem diameter, plant height, plant trunk, fresh weight, and seedling strength index of the plant are significantly improved, while also promoting the formation of chloroplast matrix and basal grain layer and the output of assimilates. Under the red blue light ratio of 8:1, cucumber seedlings had the highest plant height, stem diameter, leaf area, seedling strength index, aboveground and whole plant fresh weight, and the seedling leaves had high POD and APX activities; Under the red blue light ratio of 6:3, the root activity, soluble protein and sugar content, and net photosynthetic rate of cucumber seedlings were the highest, and SOD activity was relatively high. The use of a combination of red, green, and blue light is beneficial for the accumulation of dry matter in red bean sprouts. Adding green light has a promoting effect on the accumulation of dry matter in red bean sprouts, with the most significant increase observed in the red green and blue light ratio of 6:2:1; The red and blue light ratio of 8:1 had the best effect on the elongation of the hypocotyl of red bean sprouts. The red and blue light ratio of 6:3 had a significant inhibitory effect on the elongation of the hypocotyl of red bean sprouts, but the soluble protein content was the highest. When using a red and blue light ratio of 8:1 for the treatment of luffa seedlings, the strongest seedling index and highest soluble sugar content were observed. When using a red and blue light ratio of 6:3, the highest chlorophyll a content, chlorophyll a/b ratio, and soluble protein content were observed in luffa seedlings. When using a red blue light ratio of 3:1 for celery, it can effectively promote the increase of celery plant height, petiole length, number of leaves, dry matter quality, VC content, soluble protein content, and soluble sugar content; In tomato cultivation, increasing the proportion of LED blue light promotes the formation of lycopene, free amino acids, and flavonoids, while increasing the proportion of red light promotes the formation of titratable acids; When using a red blue light ratio of 8:1 on lettuce leaves, it is beneficial for the accumulation of carotenoids, effectively reducing their nitrate content and increasing their VC content.
Light intensity
Plants are more susceptible to light inhibition when growing under weak light than under strong light. The net photosynthetic rate of tomato seedlings varies with light intensity [50, 150, 200, 300, 450, 550] μ The increase in mol/(m? · s) shows a trend of first increasing and then decreasing, and reaches 300 μ Reached maximum at mol/(m? · s); The plant height, leaf area, water content, and VC content of lettuce are within 150 μ Significant increase in mol/(m? · s) light intensity treatment at 200 μ Under the treatment of mol/(m? · s) light intensity, the fresh weight, total weight, and free aromatic acid content of lettuce aboveground parts were significantly increased, while at 300 μ Under the treatment of mol/(m? · s) light intensity, the leaf area, water content, chlorophyll a, chlorophyll a+b, and carotenoids of lettuce all decreased; Compared to darkness, with the increase of LED supplementary light intensity [3, 9, 15 μ The increase of mol/(m? · s) significantly increased the content of chlorophyll a, chlorophyll b, and chlorophyll a+b in black bean sprouts and vegetables, with a light intensity of 3 μ At mol/(m? · s), the VC content is highest at 9 μ The content of soluble protein, soluble sugar, and sucrose is highest at mol/(m? · s); Under the same temperature conditions, with the increase of light intensity [(2-2.5) lx x x 103 lx, (4-4.5) lx x x 103 lx, (6-6.5) lx x 103 lx], the seedling growth time of chili seedlings is shortened, and the soluble sugar content increases, but the chlorophyll a and carotenoid content gradually decreases.
Illumination time
Extending the light exposure time appropriately can alleviate the weak light stress caused by insufficient light intensity to a certain extent, help accumulate photosynthetic products in horticultural crops, and achieve the effect of increasing yield and improving quality. The VC content of sprouted vegetables shows a gradually increasing trend with the extension of light time (0, 4, 8, 12, 16, 20 hours/day), while the content of free amino acids, SOD, and CAT activity all show a decreasing trend; With the extension of lighting time (12, 15, 18 hours), the fresh weight of cabbage plants shows a significant increase trend; The VC content in the leaves and stems of Chinese cabbage was highest at 15 and 12 hours, respectively; The soluble protein content in the leaves of Chinese cabbage gradually decreased, but the highest was observed in the stems after 15 hours of treatment; The soluble sugar content in the leaves of cauliflower gradually increases, while the highest content is observed in the stems after 12 hours. In the case of a red and blue light ratio of 1:2, compared with a 12 hour light time, the 20 hour light treatment reduced the relative content of total phenols and flavonoids in green lettuce. However, in the case of a red and blue light ratio of 2:1, the 20 hour light treatment significantly increased the relative content of total phenols and flavonoids in green lettuce.
From the above, it can be seen that different light formulas have different effects on the photosynthesis, light morphogenesis, and carbon and nitrogen metabolism of different crop types. How to obtain the optimal light formula, light source configuration, and formulate intelligent control strategies needs to take plant species as the starting point, and appropriate adjustments should be made according to the demand for horticultural crops, production goals, production factor conditions, etc., to achieve intelligent control of light environment under energy-saving conditions and the goal of high-quality and high-yield horticultural crops.
Existing problems and prospects
The significant advantage of LED fill lights is their ability to intelligently combine and adjust spectra based on the photosynthetic characteristics, morphological construction, quality, and yield requirements of different plants. Different types of crops and different growth stages of the same crop have different requirements for light quality, light intensity, and light cycle. This requires further development and improvement of light formula research, forming a huge light formula database, and combining with the research and development of professional lighting fixtures, in order to achieve the maximum value of LED fill lights in agricultural applications, thereby better saving energy consumption, improving production efficiency and economic benefits.
The application of LED fill lights in facility horticulture has shown strong vitality, but the price of LED fill lights is relatively high, and the one-time investment is large. The fill light requirements for various crops under different environmental conditions are not clear, and the fill light spectrum, intensity, and fill light time are not reasonable, which inevitably leads to various problems when using fill lights.
However, with the advancement and improvement of technology, the production cost of LED fill lights has decreased, and LED fill lights will be more widely used in facility horticulture. At the same time, the development and progress of LED supplementary lighting technology system combined with new energy will enable the rapid development of factory agriculture, household agriculture, urban agriculture, and space agriculture to meet the needs of people for horticultural crops in special environments.

The function characteristics and application of solar street lamp components
The function characteristics and application of solar street lamp components In the development of new energy, it is recognized at home and abroad that the highest technical content and the most promising development prospect is solar power generation. Solar power generation mainly has solar thermal power generation and solar solar power generation in two ways. This paper focuses on solar energy generation. Solar energy power generation is the direct conversion of solar energy into electrical power generation, can be divided into photovoltaic power generation, light induction power generation, photochemical power generation and photobiological power generation four kinds; At present, the most widely used photovoltaic power generation is to directly convert the photovoltaic effect generated by the light irradiated to the solar panel into direct current energy output, and its structure is generally composed of solar panels, batteries, controllers, inverters and brackets. The disadvantages of photovoltaic power generation are: high initial investment cost; Lower energy density; Intermittent power generation; Greatly affected by climatic conditions (can not generate electricity on rainy days); Photovoltaic power generation is currently mainly used in three aspects, namely: to provide power for places without power; Grid-connected power generation; Production of solar electronic products, such as all kinds of solar chargers, solar lamps (including solar street lights), solar water heaters, etc. 1.1 The basic characteristics of solar panels and their applications In order for the solar panel components to receive as much solar radiant energy as possible during the year, an optimal Angle is selected for the solar panel components during installation. Through the calculation of the special model, the change value of the monthly average solar irradiance of different inclination planes can be obtained. On the inclined plane of different angles, the solar irradiance varies greatly. Therefore, when installing solar panel components, the suitable inclination Angle should be selected through the test to obtain the maximum solar irradiance. 1.2 The basic characteristics and application of solar battery The solar battery group is the energy storage device of the solar panel, its role is to store the electric energy emitted by the panel when there is sunshine, and it is used for load at night or cloudy and rainy days. The battery is composed of a number of batteries in series and parallel, and its capacity requires that it can meet the power supply time and power supply requirements of street lights in the days without solar radiation. At present, lead-acid batteries are commonly used in China, and cadmium-nickel batteries can also be used in important occasions, but the latter price is higher. The storage battery is chemical energy, it converts direct current energy into chemical energy storage, and then converts chemical energy into electrical energy when needed, visible energy conversion process is reversible, the former is called battery charging, the latter is called battery discharge. Therefore, in the photovoltaic power generation system, the battery plays a role in the storage and regulation (release) of the electric energy generated by the system; Since the power output of the photovoltaic power generation system changes every day, the battery can also provide relatively stable electricity when the sunshine is insufficient or the photovoltaic power generation system needs to be repaired. 1.3 The basic characteristics and application of solar lighting fixtures Since LED is a DC power supply device, it is easy to be made into DC lamps, which are widely used in DC systems, such as solar lighting products. It has flat type ultra-high brightness LED, single beam type ultra-high brightness LED and beam type ultra-high brightness LED combination of three, because a single beam type ultra-high brightness LED light tube light direction is too strong, the comprehensive visual effect is poor, so, Flat type ultra-high brightness LED or flat type and beam type ultra-high brightness LED combination should be preferred, multiple leds are concentrated together, arranged and combined into a certain regular LED light source, as a solar street lamp lighting fixture. 1.4 Solar street lamp overcharge and overdischarge protection function In the application of solar street lights, attention should be paid to the control of overcharge and overdischarge of the battery. The so-called overcharge control is to disconnect the charging circuit in time when the battery is in the overcharge state, and the over-discharge control is to disconnect the discharge circuit in time when the battery is in the over-discharge state, which is to protect the battery and extend its service life. The basis for judging overcharge and overdischarge is the change of the battery voltage: When there is sunlight on a sunny day, the solar photovoltaic panel absorbs light energy through the relay switch normally closed point to charge the battery, when the battery voltage is higher than 26V, the storage battery is in an overcharged state, the relay switch normally closed point is broken, the normal open point is closed, the charging circuit automatically disconnected, stop charging the battery. Realize overcharge protection function; At night, the battery supplies power to the street lamp. When the voltage of the battery is lower than 22V, the battery is in the overdischarge state, the relay switch is turned from the normally closed point to the normally open point, the discharge circuit is automatically disconnected, and the power supply to the load (street lamp) is stopped, and the overdischarge protection function is realized.

What causes oily scalp?
Tumblr media
As someone who has battled an oily scalp for years, I frequently wonder what results in this aggravating problem. I've learnt through my research that a number of things can lead to excessive scalp oil production.
Sebaceous glands that are working too hard are one of the main reasons of an oily scalp. Sebum, a natural oil produced by these glands, aids in lubricating and protecting the scalp and hair. An oily scalp might result from these glands producing too much sebum when they are hyperactive.
Hormonal imbalances are another cause that may lead to an oily scalp. Sebum production is heavily influenced by hormones, and variations in hormone levels can result in an increase in oil production. This explains why menopause, pregnancy, and puberty are frequently times when oily scalp is more prevalent.
Genetics, a bad diet, and specific drugs are further potential contributors to oily scalp. Additionally, an oily scalp may result from utilising the incorrect hair care products. For instance, employing items with thick oils or silicones can make the hair heavy and contribute to an oily scalp.
While there are many different factors that can contribute to an oily scalp, the good news is that there are also many effective treatments available. One treatment that has been gaining popularity in recent years is red light therapy hat.
Tumblr media
Low-level red light is used in red light therapy, a non-invasive procedure, to stimulate hair follicles and encourage hair growth. The treatment works by boosting blood flow to the scalp, which then supplies the hair follicles with essential nutrients and oxygen. This enhances scalp health while supporting hair growth and strengthening.
Red light treatment has been demonstrated to be useful in regulating scalp oil production in addition to boosting hair growth. Red light treatment has been shown in studies to help regulate sebum production, resulting in a decrease in oily scalp.
According to one study in the Journal of Cosmetic Dermatology, red light therapy can help people with oily scalps produce less scalp oil. For eight weeks, the study subjects underwent three sessions of red light therapy per week. The subjects' hair thickness and density also improved, and the researchers discovered a considerable reduction in scalp oil production at the conclusion of the study.
Adenosine triphosphate (ATP), a chemical that gives cells energy, can be stimulated by red light treatment, according to another study that was published in the Journal of Photochemistry and Photobiology. Given that hair follicles need energy to form new hair, this may aid in the promotion of hair growth.

After two hours, sunscreen that includes zinc oxide loses effectiveness, becomes toxic: study
Sunscreen that includes zinc oxide, a common ingredient, loses much of its effectiveness and becomes toxic after two hours of exposure to ultraviolet radiation, according to a collaboration that included Oregon State University scientists.
The toxicity analysis involved zebrafish, which share a remarkable similarity to humans at the molecular, genetic and cellular levels, meaning many zebrafish studies are immediately relevant to people.
Findings were published today in Photochemical & Photobiological Sciences.
The research team, which included College of Agriculture Sciences faculty Robyn Tanguay and Lisa Truong and graduate fellow Claudia Santillan, sought to answer important but largely neglected questions regarding the massive global sunscreen market, predicted by market data firm Statista to be worth more than $24 billion by the end of the decade.

 The fascinating cold laser story
 Albert Einstein proposed it way back in 1917. It sounded like something straight out of a science fiction novel. The use of low-level focused light waves as a therapy to heal tissue. But, just like most of his brilliant ideas, Einstein’s theory was WAY ahead of its time and everyone laughed at him.
 It was 43 years after Einstein’s prediction that he was proven right and low-level light was first developed into a therapy. In 1960, Hungarian surgeon, Endre Mester, first reported his experience using laser light to treat non-healing infections and inflammations (swelling) in rats. Mester reported a 70% success rate treating these infections which led to the development of a science he called “laser biostimulation,” or the stimulation of the local immune system.
 Today there is an entire science field devoted to this subject call photobiology – the study of how light affects living things.
 Since 1967, more than 2,000 clinical studies have been published worldwide on cold lasers. And on January 17, 2002, the first patent and market clearance was given by the FDA to a cold laser for the non-surgical treatment of joint pain. And listen to this: the study documented 94% of patients felt some improvement!
 In 2004, another study of cold laser therapy for treatment of knee joint pain revealed a 62% success rate in significantly reducing pain. This was achieved after approximately 10 treatments that lasted ONLY 15 minutes each.
 And with so many modern medical “cures” causing worse problems than the conditions they were initially intended to treat, one of the most important benefits was … no documented side effects! Not one – in fact, the only warning was not to shine the laser directly in the eye for a prolonged period of time.

Which plant supplement light is more suitable for greenhouse crop supplement light?
When planting crops in large sheds, you must worry about the lighting of the plants. If the sun is insufficient, it will affect the growth and flowering of the crops. Therefore, people will think of using LED full-spectrum plant supplement light to supplement light for plants.
5 light sources that affect plant growth
  Light is the basic environmental factor for plant growth and development. It is not only the basic energy source for photosynthesis, but also an important regulator of plant growth and development. The growth of plants is not only restricted by the amount of light or light intensity (photon flux density, photonfluxdensity, PFD), but also by light quality, that is, light and radiation of different wavelengths and their different composition ratios.
  The solar spectrum can be roughly divided into ultraviolet radiation (ultraviolet, UV<400nm, including UV-A320~400nm; UV-B280~320nm; UV-C<280nm, 100~280nm), visible light or photosynthetically active radiation (photosynthetically active radiation, PAr , 400~700nm, including blue light 400~500nm; green light 500~600nm; red light 600~700nm) and infrared radiation (700~800nm). Due to the absorption of ozone in the stratosphere (stratosphere), uc-c and most of uv-b cannot reach the surface of the earth. The intensity of uv-b radiation reaching the ground changes due to geographic (altitude and latitude), time (day time, seasonal changes), meteorological (cloud layer, thickness, etc.) and other environmental factors such as atmospheric pollution. .
  Plants perceive subtle changes in light quality, light intensity, duration and direction of light in the growing environment, and initiate changes in the physiological and morphological structures necessary for survival in this environment. Blue light, red light and far-red light play an extremely critical role in controlling the light morphogenesis of plants. The photoreceptors of phytochrome (Phy), cryptochrome (Cry) and photoreceptors (Phot) receive light signals and trigger plant growth and development changes through signal transduction.
  The monochromatic light mentioned here refers to light in a specific range of wavelengths. The wavelength range of the same monochromatic light used by different experimental subjects is not completely the same, and it often overlaps with other monochromatic lights with similar wavelengths to different degrees, especially before the emergence of LED light sources with good monochromaticity. in this way. Naturally, different or even contradictory results will be produced.
  Red light
  Red light (R) inhibits internode elongation, promotes lateral branching and tillering, delays flower differentiation, and increases anthocyanins, chlorophyll and carotenoids. Red light can promote the positive light movement of Arabidopsis roots. Red light has a strong positive effect on the resistance of plants to biotic and abiotic stresses.
  Far red light (FR) can counteract the red light effect in many cases. Low r/fr ratio leads to reduced photosynthetic capacity of kidney beans. In the growth room, white fluorescent lamps are used as the main light source, and LEDs are used to supplement far red radiation (emission peak 734nm) to reduce the content of anthocyanins, carotenoids and chlorophyll, and make the plant fresh weight, dry weight, stem length, leaf length and leaf length. Width increases. The effect of supplementing fr on growth may be due to the increase in light absorption caused by the increase in leaf area. Arabidopsis thaliana grown under low r/fr conditions has larger and thicker leaves, larger biomass, and strong cold adaptability than plants grown under high R/FR. Different ratios of R/FR can also change the salt resistance of plants.
  Blu-ray
  Generally speaking, increasing the share of blue light in white light can shorten internodes, reduce leaf area, reduce relative growth rate and increase nitrogen/carbon (n/c) ratio.
  Blue light is needed for chlorophyll synthesis and chloroplast formation in higher plants, as well as sun chloroplasts with high chlorophyll a/b ratio and low carotenoid levels. Under the red light, the photosynthetic rate of the cells of the algae will gradually decrease, and the photosynthetic rate will quickly recover after turning to blue light or increasing some blue light under continuous red light. After dark-growing tobacco cells were transferred to continuous blue light for 3 days, the total amount and chlorophyll content increased sharply. Consistent with this, the dry weight of cells per unit volume of culture medium will also increase sharply, and will increase very slowly under continuous red light.
For the photosynthesis and growth and development of plants, red light alone is not enough. Wheat can complete its life cycle under a single red LED light source. To obtain very large plants and a large number of seeds, an appropriate amount of blue light must be added (Table 1). The yield of lettuce, spinach and radish grown under a single red light is lower than that of plants grown under a combination of red and blue light, while the yield of plants grown under a moderate amount of red and blue light is comparable to that of plants grown under a cool white fluorescent light. Similarly, Arabidopsis thaliana can produce seeds under a single red light. Compared with plants grown under a cool white fluorescent light, as the proportion of blue light decreases (10%~1%), plants grown under a combination of red and blue light Bolting, flowering and fruiting will be delayed. The seed yield of plants grown under a 10% combination of red and blue light is only half of that of plants grown under a cool white fluorescent lamp. Excessive blue light inhibits plant growth, shortens the internodes, reduces branches, reduces leaf area and reduces total dry weight. There are obvious species differences in the blue light needs of plants.
Although some studies with different types of light sources have shown that the differences in plant morphology and growth and development are related to the different proportions of blue light in the spectrum, the conclusions are still questionable because the composition of the non-blue light emitted by the different types of lamps is also different. Although the dry weight and net photosynthetic rate per unit leaf area of ​​soybean and sorghum plants grown under the same intensity of fluorescent lamps are significantly higher than those of plants grown under low-pressure sodium lamps, these results cannot be attributed to the lack of blue light under low-pressure sodium lamps. I am afraid it is also related to too much yellow and green light and too little orange-red light under low-pressure sodium lamps.
  Green light
  The dry weight of tomato seedlings grown under white light (including red, blue and green light) was significantly lower than that of seedlings grown under red and blue light. The results of spectroscopic detection of growth inhibition in culture showed that green light is a harmful light quality with a peak at 550nm. The plant height, freshness, and dry weight of marigolds grown under light that removes the green light will increase by 30%-50% compared to plants grown under full-spectrum light. Full-spectrum light supplementing green light leads to short plants and reduced dry and fresh weight. Removal of green light enhances marigold blooming, while supplementation of green light inhibits the blooming of dianthus and lettuce.
 There are also research reports on green light promoting plant growth. Kim et al. (2006) summarized the experimental results of red and blue combined light (LEDs) supplementing green light and concluded that plant growth is inhibited when green light exceeds 50%, and plant growth is enhanced when the proportion of green light is less than 24%. Although the addition of green light to the red and blue combination light background provided by the LED led to a significant increase in the lettuce ground stem, the conclusion that the addition of green light strengthens plant growth and produces more biomass than under cold white light is a problem : (1) The dry weight of biomass they observed is only the dry weight of the upper part of the ground. If the dry weight of the underground root system is included, the results may be different; (2) Lettuce grown under red, blue and green lights on the ground The dry weight of the part is larger than that of plants grown under cool white fluorescent lamps. It is likely that the three-color lamps contain much less green light (24%) than cool white fluorescent lamps (51%). That is to say, the green light inhibiting effect of cool white fluorescent lamps is greater than that of cold white fluorescent lamps. Three-color light; (3) The photosynthetic rate of plants grown under combined red and blue light is significantly higher than that of plants grown under green light. The results support the previous speculation.
  The green light effect is usually the opposite of the red and blue light effects. Green light can reverse blue light and promote the opening of stomata. Treating the seeds with a green laser can quickly grow radishes and carrots to twice the size of the control. A dim pulse of green light can accelerate the elongation of seedlings growing in the dark, that is, promote the elongation of the stem. Treatment of Arabidopsis albino seedlings with a single green light (525nm±16 nm) pulse (11.1 μmol·m-2·s-1, 9s) from an LED plant light source resulted in a decrease in plastid transcripts and an increase in stem growth rate .
  (2007) Based on the research data of plant photobiology over the past 50 years, the role of green light in plant development, flowering, stomata opening, stem growth, chloroplast gene expression and plant growth regulation was discussed. The blue light sensor harmoniously regulates the growth and development of plants. It must be noted that in this review, the green light (500~600nm) is expanded to include the yellow part of the spectrum (580~600nm).
  Yellow light
  Yellow light (580~600nm) inhibits the growth of lettuce. Only yellow light (580~600nm) can explain the difference between the growth effects of high-pressure sodium lamps and metal halide lamps, that is, yellow light inhibits growth. Yellow light (peak at 595nm) inhibits cucumber growth stronger than green light (peak at 520nm).
  Some contradictory conclusions about the interweaving of yellow/green light effects may be due to the inconsistent wavelength range of light used in those studies.   Ultraviolet radiation
  Ultraviolet radiation reduces plant leaf area, inhibits hypocotyl elongation, reduces photosynthesis and productivity, makes plants vulnerable to pathogens, but can effectively promote anthocyanin synthesis.
Supplementation of uv-b led to an increase in the total biomass of 4 cultivars and 12 cultivars (6 of which reached a significant level); those cultivars that are sensitive to UV-B have both leaf area and tiller number Obviously reduced; there are 6 cultivars with increased chlorophyll content; 5 cultivars with significantly reduced leaf photosynthetic rate, and 1 cultivar with significantly increased chlorophyll content (its total biomass also increased significantly).
  The ratio of UV-B/PAR is an important determinant of the response of plants to UV-B. UV-B and PAR together severely affect the morphology and oil yield of peppermint. The production of very high-quality oil requires a high level of unfiltered natural light.
  It needs to be pointed out that although laboratory studies on the effects of UV-B are useful in identifying transcription factors and other molecular and physiological factors, the results usually cannot be mechanically extrapolated to the natural environment.
The led plant supplement light is specially developed to supplement the light for plants. The spectrum is in line with the absorption of sunlight by plant growth, and different powers can meet the requirements of crop growth for light intensity. There are many types of plant supplement light, so which kind of supplement light is cheap and easy to use?
From the research and development process, there are high-pressure sodium lamps, HID lamps, LED supplementary lights, and the fifth generation of plant supplementary lights-laser supplementary lights. Among these types of fill light, the laser plant fill light is the latest generation of fill light, so the effect and advantages will be better than the previous types of fill light.
The laser plant supplement light is a special LED plant growth lamp with a specific spectrum wavelength designed to replace sunlight with laser synthesis spectrum technology, promote plant growth photosynthesis, and create a suitable growth environment for plants. She occupies less space (one lamp per mu of land), consumes less electricity (3 kWh a month), is energy-saving and environmentally friendly, and the spectrum can be combined. The results are also good after experiments.
If you want to use the LED plant supplement light to have a good effect, in addition to using the appropriate supplement light, you must also have the correct use method, such as the distance between the led plant supplement light and the plant, and the use time of the supplement light pay attention. Then let's take a look at the use of plant fill light. How long is it suitable for general lighting?
The role of led plant supplement light is to give plants when the natural light is insufficient, so we must pay attention to it, if the weather is usually sunny and the light is sufficient, then there is no need to use supplement light, otherwise it will not only consume electricity, but the effect will not be comparable. The effect of natural light. If there is sufficient sunlight during the day, you can add light for 2-3 hours in the morning or evening. If it is raining on a cloudy day or when the light is insufficient for a long time in a hazy day, you must use the fill light for a long time to fill up the light. You can fill up the light throughout the day, and you can also extend the fill light time appropriately at night.
If it is sunny during the day, you can add light for 4-5 hours a day. If the light is weak during the day, you can add light throughout the day. If the crops have higher requirements for light, you must adjust the time of the light according to the actual situation. However, the crops also have to "rest" at night, so do not fill up the crops overnight, otherwise it will have a counterproductive effect.

Laser Cap Helps Fight Baldness, Thickens Hair Even While Watching TV or Eating Popcorn
A new laser cap that uses low light laser therapy can help fight signs of hair loss to prevent men from completely going bald. It can be inserted in a ball cap and use at home while relaxing.
This is a novel way to address problems of male pattern baldness that affects around 42% of men in ages between 18 to 49 who experience moderate to extensive hair loss.CRECIMIENTO DEL CABELLO GORRA
Laser Cap Helps Fight Baldness By Thickening the Hair Even While Watching TV or Eating Popcorn
According to Physiopedia, the term laser is the acronym for Light Amplification by Stimulated Emission of Radiation. Different technologies have made use of laser technology for various practical uses.
Low-level light therapy (LLLT) was discovered by Hungarian physician Endre Mester in the 1960s. It is a non-invasive light source that generates a single wavelength of light commonly used in medicine by physiotherapists to treat musculoskeletal conditions.
This applies to the field of medicine is called photobiology or biostimulation. It can accelerate the repair of connective tissue and act as an anti-inflammatory agent.
A study entitled "The growth of human scalp hair mediated by visible red light laser and LED sources in males," showed that LLLT could be used to improve hair count in both men and women who suffer from androgenic alopecia, the most common form of hair loss.
How Does Low Light Therapy Regrow Hair? Lasers typically emit hot light, but LLLT does not generate heat, which is why it is sometimes referred to as cold laser therapy.
According to Futurism, low light laser therapy works by emitting light from the laser diodes that enhances blood circulation in the skin, which transports more nutrients. Therefore, LLLT stimulates the metabolism and protein synthesis in hair follicle cells in a process called photobiomodulation.
Prolonged usage of photobiomodulation could activate hair follicles and switch them from their dormant or telogen phase into their active or anagen phase that enables hair to regrow in places where it stopped growing.
LLLT in Laser Cap System For Hair Regrowth DEPILACIÓN LÁSER LLLT was only used in clinics before, but several companies have now made it possible to treat baldness even at the comfort of the user's home while sitting on a couch and watching TV or eating some snacks.
For example, Kiierr Laser Cap is equipped with a helmet that can fit inside a regular baseball cap. The laser diodes in each Kiierr laser cap emit a wavelength of 650 nanometers that is clinically proven effective. The more intense the light is emitted, the lesser time is needed for the completion and success of the treatment.
The results of using LLLT could be visible after three to four months, with maximum results after six or seven months. Meanwhile, using Kiierr 272 Premium for 30 minutes every day is 93% effective in regrowing and thickening hair.
