Water is the main element of the human body, vital for the functioning of the organs and thermoregulation. More substances dissolve in water than in any other solvent. Most of the chemical reactions that take place in our cells require water. Water is necessary to transport nutrients and oxygen to all cells in the body. It helps convert food into energy and absorb nutrients. Water maintains the stability of body temperature and protects vital organs, participates in maintaining the shape of cells and organs, and is important for skin health. Water helps the body get rid of waste: many toxins come out with sweat and urine, water (tears, saliva) washes and dilutes caustic substances. Water also promotes respiration.
