| Water and the body | |
Playing sport or exercising uses up the body's water store. It is essential to drink water before, during and after sport or other physical activity.

Our bodies use about 10-11 glasses of water in the removal of waste. Each day our kidneys excrete about five glasses of water as urine; about two glasses are lost through the skin as perspiration; and a cup of water is lost through breathing.
Avoiding dehydration is the main reason sports people need to drink water.
Sports of higher intensity, involving more vigorous energy expenditure, call for more water consumption.
Remember, if you feel thirsty it's too late - you have already begun to dehydrate. Try to drink before your thirst develops.
