Benefits of water are easy to guess. Respiration, digestion, assimilation, metabolism, elimination, waste removal, and temperature regulation are bodily functions that can only be accomplished in the presence of water. Water is essential in dissolving and transporting nutrients such as oxygen and mineral salts via the blood, lymph, and other bodily fluids. Water also keeps the pressure, acidity, and composition of all chemical reactions in equilibrium.
Only oxygen is more essential than water in sustaining the life of all organisms. Human beings can live around 5 weeks without protein, carbohydrates, and fats but just 5 days without water in a moderate climate. Its circulation between the blood and bodily organs is perpetual and always maintained in proper balance; however, a certain amount is eliminated daily through evaporation or excretion and must be replaced.
Most of this water is removed by the kidneys, through which the entire blood supply passes and is filtered 15 times each hour. Whenever the body becomes overheated, two million sweat glands excrete perspiration which is 99% water. The heat of the blood evaporates the sweat, cooling the body and keeping the internal organs at a constant temperature. A minimal but consistent loss of water occurs during the processes of breathing and tearing. Moisture is breathed out from the water-lined nasal passages and the lungs. Dry air draws off more water than humid air. Tiny tear
ducts carry a liquid solution to the upper eyelids, which lubricate the eyes 25 times every minute. The tears then pass down to the nose where they evaporate.
To replace lost water, approximately 3 qt is needed by the body each day under normal conditions. More strenuous activity, a high climate temperature or a diet too high in salt may increase this requirement. The sense of thirst is controlled by a part of the forebrain called the hypothalamus. Metabolic water is produced as a by-product of the food combustion process yielding as much as a pint per day. Foods can provide up to 11⁄2 qt. For example, fruits and vegetables are more than 90% distilled water. Even dry foods like bread and crackers are 35 and 5% water, respectively. Drinking water is the other source of replenishment. Municipal water treatment systems are mainly concerned with disinfection and do not remove most chemicals. Because of environmental pollution, there is probably not a water source that is not contaminated to some degree. The most efficient removal and reduction of the widest range of contaminants is in bottled water, purified by ozone, reverse osmosis, and distillation, or a combination.
Needed minerals do not have to be obtained from drinking water as they are found in a wide range of foods in a varied and wholesome diet.
Don’t forget the benefits of water if you want to have a nice and healty skin and body.
