Since most of the body is water-based, therefore, it plays key role and has profound effects on the functioning of every organ of the body. It plays vital role on body chemistry, health disease. We can live for 50 days without food but hardly 10 days without water. Besides the air we breathe, water is foundation and critical element not only for our health and physiology but also for our survival.
It is most vital nutrient for body’s every function. Water is essential to every one of the millions of chemical processes that maintain our bodies i.e. from digestion and respiration to muscle activity, reproduction, and mental processes. Major functions of water are enumerated hereunder:
Facilitates normal functions of body-processes and provides energy
Delivers oxygen and nutrients to different parts of the body
Regulates blood pressure and helps body maintain constant temperature
Assists in digestion, metabolic process and circulatory system
Prevents and alleviates constipation
Helps elimination of toxins, impurities and waste from the body
Acts as lubricant nd cushion to joints, protects organs and tissues.
Strengthens the immune system.
Decreases and prevents risk of cancer of colon, breast and bladder
Prevents heart disease, renal stones
Resists diseases and unnatural premature aging
Acts as shock absorbers inside the eyes and spinal cord
Adds glow to skin and keeps it healthy, resilient, moist, supple, and clear and prevents pre-mature aging.
Improves focus and behavior.
Every cell of every living organism must consume and excrete water in order to function. We lose body water through four processes:
Perspiration
Respiration
Urination
Defecation
In other words the body water is excreted by way of sweat, breathing, urine, stool and tears. The body is unable to store or build up reserves of water; therefore, it is most important to replenish this loss continuously to maintain water balance for optimal functioning of the body cells and organs.
