GENERAL CARE OF THE BODY: HOW MUCH WATER SHOULD YOU DRINK?
The amount of water drunk each day is usually correctly adjusted by your sense of thirst. The body loses about a quart of water each day in the form of invisible perspiration on the skin and as water vapour expired into the air from the lungs. This loss of water plus the quart or more of water contained in the daily urine must be supplied chiefly by:
- Water in solid foods. For example, vegetables and fruits are high in water content.
- Water in fluids such as milk, soups, and beverages.
- Water taken as such. This will balance any difference between the intake and the output.
In hot weather, or when you work in a hot area, your body requires more water to compensate for the loss of sweat. Visible perspiration may amount to many quarts a day. Because the sweat contains salt too, it is necessary to replace the salt loss as well.
