Women need about 2500ml of water every day, and it is good for the skin to reach these drinking amounts. The demand for water is mainly affected by age, environmental temperature, physical activity and other factors. The amount of urine excreted by human body in one day is about 1500ml, and the water lost from feces, breathing and skin is about 2,500ml. Therefore, the daily water demand of healthy adults is about 2,500ml, of which drinking water accounts for about 50%, water contained in food accounts for about 40%, and water produced by metabolism in the body accounts for 10.

Adults living in mild climate and less physical activity should drink at least 1200ml every day. Under the condition of high temperature or strong physical labor, it should be increased appropriately. Drink plenty of water when you are sick, especially when you have a fever, because every time your body temperature rises 1, your metabolism will accelerate by about 7%.

Water is not only the main component of the body, but also has many physiological functions, mainly divided into free water and bound water.

The solubility of water is very strong, and many substances can be dissolved in water and dissociated into ionic states, which plays an important role. Protein and fat insoluble in water can be suspended in water to form colloid or emulsion, which is convenient for digestion, absorption and utilization; Water directly participates in the redox reaction in human body, promoting various physiological activities and biochemical reactions; Without water, it is impossible to maintain physiological activities such as blood circulation, breathing, digestion, absorption, secretion and diarrhea, and metabolism in the body cannot be carried out; Water has a large specific heat, which can regulate body temperature and keep it constant.
