What is the connection between water and human health?

Life comes from water, without which human beings can't live. The functions of water in human body include: maintaining cell morphology, increasing metabolic function, regulating the normal circulation of blood and tissue fluid, dissolving nutrients to make them easy to absorb and transport, helping to excrete wastes in the body, releasing heat, regulating body temperature and maintaining blood acid-base balance. In a word, water is the key to human function. Without water, there is no life. Generally speaking, the human body needs 2 ~ 3 liters of water every day, that is, 10 glass of water, of which 4 cups are from food and 6 cups are from drinks. If the intake of water is insufficient, the human body can reduce the discharge of water through regulation mechanism, but when it is seriously insufficient, it will reduce the water in the body. When the water content drops to 2% ~ 10% of the body weight, it can cause substance metabolism disorder in the body due to dehydration; When the water content drops to 7% ~ 14% of body weight, severe dehydration symptoms and signs appear; When the water content drops more than 14%, it is life-threatening. Many people only drink water when they are dry, which is a misunderstanding. Dry mouth is only the last signal sent by the body when it is approaching the dehydration stage, so we should attach great importance to drinking water and be sure to drink enough water consciously, which will make you healthier, more energetic and live longer.
