Water helps nearly every part of the human body function.The human body contains over 75% water. Water is the transport system which moves nutrients around the body as well as carrying waste out of the body. Water breaks down food, keeps your body temperature balanced and keeps you skin elastic. We can live for weeks without food but only a few days without water. The following are just some of the important things water does in the body:
The human body contains between 55-75% water depending on the ratio of body fat to muscle.
Water is vital for body temperature regulation, therefore fluid replacement is vital. During summer when the temperature increases, your body requires even more fluid to maintain it's normal body temperature. Even when there is zero intake of water there are always unavoidable losses.
Water In: Solid Foods (34 ozs.), Metabolic Water (10 ozs.) and Beverages (34 ozs.)
Water Out: Evaporation (min 34 ozs.), Sweat ???, Faeces (3+ ozs.) Urine?
Remember! Although thirst indicates a lack of fluid, it is not a reliable measure of water need. It is important to pay attention to the signals of water loss and minimise risk of dehydration before thirst sets in. Establishing a strong fluid habit is important for everyone.
