What is the standard for an adult to drink water every day?

The daily water demand of healthy adults is about 2500ml, 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%. ?

The demand for water is mainly affected by age, environmental temperature, physical activity and other factors. The amount of urine excreted by the human body in one day is about 1500ml, and the total water consumption is about 2,500ml with the addition of water lost from feces, breathing and skin.
