Drinking water also helps the body maintain its balance of fluids, notes WebMD. The body needs water for its main functions, including digestion, circulation, and nutrient transportation and absorption. Water also helps to energize the muscles, especially when exercising. Water helps the body maintain its balance of electrolytes and fluids.
In addition, water is essential for good skin. The skin contains a lot of water and works to protect the body from water loss. Hydrating the body with water allows the skin to excrete excess fluids, giving it a healthier appearance.
Water is essential to the functioning of kidneys and the transportation of waste products from cells. Without adequate fluid intake, toxins are unable to be expelled from the body. It is also an important part of proper and regular bowel functioning. Drinking an adequate amount of water keeps the bowels moving and wards off constipation. If the body is not adequately hydrated, the colon pulls water from stool in order to obtain hydration, leading to hard stools and constipation.
