Water is a physical need of the human body. We can live without food up to 30-40 days, but without clean drinking water we won’t survive even 3-4 days. This should come as no surprise: the body of an adult consists of around 60-70 percent of water. It is contained in all tissues, and it is essential for metabolic processes, temperature regulation, nutrients transportation via the circulatory system and waste removal. It participates in almost all physiological processes. Lack of water can cause various diseases – from headache to muscle spasms and cramps.
