Dehydration leads to failure of all the body functions: digestion, synthesis, delivery and excretion of substances etc. When the body begins to suffer from dehydration, the breach of its functions do not happen for a certain period of time, due to the adaptation abilities. But as the degree of dehydration increases, the body is approaching a threshold beyond which the regulatory system can not keep the body balance.

The human body has many signals of its need in water, including the development of various pathologies, such as asthma and allergies. Among other signs are chronic pain in the stomach and the colon, rheumatoid joint pains, pains in the back and legs, headaches, colitis, and the most terrifying sign, pain in the heart. Dehydration is especially harmful to the immune system cells, its disorder causes the so-called immune diseases. They are all chronic ones: bronchitis, asthma, infertility, lupus erythematosus, scleroderma, multiple sclerosis, Parkinson’s disease, Alzheimer disease, cancer. They are complex and involve failures of many biological functions due to lack of water.

Dehydrated body needs the water but it can refill it successfully only if there is enough salt in the body. Salt keeps the water in the body and normalizes the composition of the blood and intercellular fluid. When there is not salt enough, the water is removed from the body to keep salt concentration constant. After the cells receive enough water they are not dehydrated any more, so the disorders caused by the dehydration can gradually disappear.
