How much water is appropriate to drink a day?

According to the Dietary Guide for China Residents, healthy adults need about 2,500 ml of water every day. Considering the moisture in food, the guide suggests that adults with mild physical activity should drink at least 1200ml of water every day under mild climate conditions. Take a 200ml cup as an example, that is 6 glasses of water. If the momentum of physical activity is high, or the ambient temperature is high, then drink more water.

Drink a small amount of water for many times, and allocate the drinking time to any time of the day, each time about 200ml (1 cup). In this way, it is enough for people who work in the office or students in class to drink half a cup to a glass of water every hour or so, and then drink one or two cups when they go home to rest.
