The director of the endocrinology department of the People's Hospital of Hamilton District said that the role of water on the human body is transportation, lubrication, dissolution, digestion, and regulation. 90% of human blood is water. During the process of blood flow, energy exchange and material transfer can be carried out. The reason why blood can circulate is the circulation of water. 5g Male The presence of sufficient liquid in the human body not only reduces the wear and tear between joints and tissue cells, but also maintains the coordination of movement, and can also dissolve inorganic salts and organic compounds, various enzymes, and hormones in the human body. If there is a lack of water in the human body, it will affect the absorption of many nutrients, and it will also cause the body temperature to be unbalanced and the body temperature to rise and fall.
