The human body is 75% water, while the brain alone is comprised of 85% water. The blood, consisting of 92% water, carries oxygen and essential nutrients to capillaries where they are released into a water-based fluid that surrounds the cells called lymph. From the lymphatic fluid nutrients are transferred to the cells and toxins are removed, keeping the entire system nourished and cleansed for optimum efficiency. In addition, water serves as a lubricant that cushions joints and protects tissues and organs, including the spinal chord, from shock and trauma. Neurotransmitters are transported to the nerve endings for transmission of messages on waterways. Water also regulates body temperature, aids digestion, works to keep the muscles and skin toned, and assists in weight loss. Water is so essential, that without it we could live for only a few days.
In his enlightening book, Your Body’s Many Cries for Water, Dr. F. Batmanghelidj states, "It is chronic dehydration that is the root cause of many of the diseases we confront in medicine at present." He explains that water regulates all functions of the body, and that when the system is depleted in water, disease symptoms appear as a result of the body’s attempts to ration its vital stores of water. In fact, all symptoms of aging are accompanied by slow dehydration of the organs and tissues and associated free radical damage to cells.
While most doctors tend to think that dry mouth is the primary sign of dehydration, Dr. Batmanghelidj believes that this is the last outward indication of extreme dehydration. Symptoms of dehydration may be arthritis, ulcers, colitis, constipation, high blood pressure, asthma, allergies, diabetes, low back pain, angina, migraine
