Question

Water is the most important element for the survival of man. We can go without food

for a long time but without water only for a few days. Human body contains 70 to 80

percent water. Without water we would be poisoned to death by our own waste

products. The kidneys remove urine acid and urea. These are dissolved in water and

the wastes are removed very effectively. Water is vital for chemical reactions in

digestion and metabolism. It carries nutrients and oxygen to the cells through the

blood, to help to cool the body through perspiration. By not drinking enough water,

many people gain weight. It decreases digestive efficiency and organ function. Proper

water intake is a key to weight loss. If people who are trying to loss weight do not

drink enough water, the body can not metabolise that fat adequately. Minimum water

intake for healthy person is 30 ml per kg of body weight in one day. You need water if

you exercise a lot in hot climate. In the beginning you may be running to the bathroom

frequently but with the passage of time, your bladder adjusts and you urinate less

frequently but in larger amounts. So, from today, start drinking more water than you

usually consume.

Drinking water and eating foods that contain a lot of water may help prevent dehydration. Without water, dehydration can affect the body rapidly.
