New thoughts on drinking habits
Just how important is water to person's well-being ? According to many nutritionists and health experts, drinking plenty of water is perhaps the most important thing a person can do to maintain optimal physical condition.
They say that even if someone is inactive, drinking eight large glasses(2 liters) of water a day is essential to prevent dehydration.
A more active person will require even more.
Health and sports experts claim a preson can easily sweat off 3 litters of fluid per hour when exercising in hot, muggy weathe.
Without adequate replacement, dehydration can adversely affect the body's functioning.
For example without proper hydration the blood volume wiil decrease, forcing the heart to work harder to circulate nutrients.
Less water means less glucose goes to working muscles, and less lactic acid is
carried away.
There is also less water to sweat off, and because sweating is how a body cools itself a dehydrated person will be hotter.
Sports doctors used to warn people that drinking anything before or during physical exertion would cause cramps.
