Is an increase in lifespan possible?

Hello guys,

today, we will be discussing an eye-catching topic, yes it is really eye-catching so what is it?

Do you know that a recent study found out that every additional heartbeat per minute increased a person's overall risk of early death by 3% and their risk of heart disease by 2%?

guys

"your resting heart rate may tell your life span".

How?

let me explain,

several studies found out that among mammals, it has been observed that the calculated number of heartbeat in a lifetime is remarkably constant, despite a 40-fold difference in life expectancy.

By observing this constant total number of heart rates in a lifetime in mammals,

so it's a good reason to believe that this can be extended to the whole animal kingdom.

 A Galapagos tortoise has a heart rate of 6 beats per minute and a life expectancy of 171 years with a total number of heartbeats of 5.6 multiply 10 to the power 8 in a lifespan.

whereas,

A Rat with a heart rate of 240 beats per minute and a life expectancy of about 5 years and a total number of heartbeats of 6.3 multiply 10 to the power 8 in a lifespan.

 In humans, a reduction in heart rate may increase your life span.

 In humans, the heart beats on average 100,800times per day

and 36.8×10 to the power 6 in a year and 29×10 to the power 8 heartbeats in a lifespan ( 80 years on average ).

The heart produces and consumes approximately 30kg ATP every day, corresponding to nearly 11,000kg per year and approximately 880,000kg in a lifetime.

so this means each heartbeat has its own cost of about 300mg ATP.

A decrease in heart rate from 70 to 60 beats per minute would increase life expectancy from 80 to 93.3 years.

this means that slowing the heart rate by 10 beats/min would result in a saving of about 5 kg ATP in a day.

 So the question here comes to our mind is that why a higher heart rate has a high mortality rate.

Increased heart rate is associated with high blood pressure and metabolic disturbance that lead to hypertension, atherosclerosis, and increased cardiovascular morbidity and mortality.

So from here, what comes to our mind?

 "elevated heart rate can be considered a marker of risk".

 Studies found out that there is a close link between body temperature, metabolism, and heart rate.

they all determine the person's life expectancy.

Heart rate may determine metabolic demands and control the duration of life.

clinical studies with beta-blockers have already shown a reduction in mortality and improvement in the outcome as a result of the reduction in heart rate.

 when it comes to heart rate, it tells a whole story about you whether it's your physical status or mental status.

It's a description of your whole body's health status.

heart rate is like a speed of a car, it cannot be too high or too low.

The average human heart rate is around 72 beats per minute but doctors consider a range of about 60 to 100 beats per minute to be normal.

 Slower than 60 is bradycardia ("slow heart"); faster than 100 is tachycardia ("fast heart").

 Slow heart rate

# Among healthy individuals,

·   its a sign of being physically fit

·   a medication, such as propranolol

# its can also be a sign of some health-related disease

·   heart attack or other heart diseases

·   high level of potassium in the blood

·   underactive thyroid gland

 high heart rate

# among healthy individuals,

·   due to high caffeine or cocaine intake

·   exercising

·   pregnancy

·   excitement due to the release of the fight-flight hormone

# Diseases due to high heart rate

·   anemia

·   some cardiovascular disorder

·   low level of potassium

·   some breathing problems or asthma

·   overactive thyroid gland

·   certain medications, etc...

 How to lower your heart rate

sometimes heart shows a sudden change in heart rate due to emotional stress or physical stress,

there are some ways through which you can control this sudden spike in heart rate

·   practice breathing exercises or deep breathing exercises

·   try to remain calm ( listen to white noises )

·   exercise daily

·   go for a walk every morning

·   practice some stretching or relaxation exercises

 Tip to lower your heart rate

 1.   Exercise - it is the easiest and most effective way to lower your heart rate, exercise daily.

2.   Stay hydrated - dehydration in your body makes the heart work more to stabilize the blood flow. drink lots of water, caffeine-free beverages, and green tea.

3.   Limit alcohol intake - it causes dehydration in the body and also makes harder for the body to process and remove it from the body, it is a toxin to our body.

4.   Limit intake of stimulants such as caffeine, cocaine - such stimulants causes dehydration in your body.

5.   Maintain a healthy body weight - extra weight also puts pressure on an individual's heart.

6.   Practice relaxation techniques - activities that increase self-awareness or mindfulness decreases stress and hence lower heart rate.

7.   Eat a healthy balanced diet - eating healthy like green vegetables, legumes, lean protein, nuts, fruits, etc make a healthy heart.

 CONCLUSION

1.   your resting heart rate tells us about your health status.

2.   your life span may be foretold in your heart rate.

3.   exercise daily to stay healthy or to keep your resting heart rate low.

4.   elevated heart rate can be considered a marker of risk.
