Never rely on your thirst to guide you in your water intake. Thirst is the body s cry for help. It activates when your body is water deprived and shuts off well before you have drunk enough.

Water also helps control food intake.

Drinking water while you fly can prevent discomfort, dehydration, as well as alleviate the symptoms of jet lag. When in high altitudes, you should increase your water intake to 12-20 glasses a day. This is particularly important when you are active in elevated altitudes because the humidity is low and the oxygen rare.
