Good for your friend to do a Marathon in less than 6 hours at a mature age.
I believe in miracle, however, not that almost 6 hours without drinking water.
Dehydration is harmful to any living creatures. Short term damage: headache, cramps, unconscious, etc.; long term: waste products of metabolism accumulating in kidney, liver, muscle.
Yoga can significantly uplift muscle tone and improve flexibility. But Yoga cannot change human physiology. No way!!! Be careful with pseudo-science.
We even need water to breathe: our lungs must be moist to take in oxygen and excrete carbon dioxide. It is possible to lose a pint of liquid each day just exhaling.
Without water, we'd be poisoned to death by our own waste products. When the kidneys remove uric acid and urea, these must be dissolved in water. If there isn't enough water, wastes are not removed as effectively and may build up as kidney stones. Water also is vital for chemical reactions in digestion and metabolism. It carries nutrients and oxygen to the cells through the blood and helps to cool the body through perspiration. Water also lubricates our joints.
