Every day, your body loses water. Your body loses water each time you sweat, go to the bathroom or get tears in your eyes. This is normal. However, if you lose too much water, you may become dehydrated.

Thirst is your body's way of telling you it needs more water. It is important to keep your body hydrated with plenty of water because the blood and organs in your body need water to function properly. Drinking fluids and eating water-containing foods helps to replenish your body.
