      Water is a critical nutrient whose absence will be lethal within days. Drinking water is also called hydration.

      All the cells and organs need water to function. Good hydration helps rid the body of toxins and prevent chronic diseases[1][2]. It helps to maintain good kidney function[5]. Increased water intake appears to decrease the risk of kidney stone[10]. Water deprivation can lead to headache[3][4] in addition to impairing concentration[6][7] and increasing irritability[9]. Dehydration when exercising has shown to reduce motivation, increase fatigue and make exercise feel more difficult[8].
