Wow, drugs don't even touch the buzz from wee dip in the cold waters. Add to that, the significance of the positive health benefits your immune system gets. I would definitely recommend this and even a 30 second (SAFE) drop into water at around 1-3 degrees C (around 20 ish Fahrenheit) for a less than a few minutes will leave a lasting impression. DON'T BE FOOLISH, WRECKLESS OR IRRESPONSIBLE. If you can safely experience this, please, please, please go nuts coz it's so energising 馃挀
