How much water should the human body consume every day under normal circumstances to be healthy?

The water intake of normal people from diet and drinking water every day is about 2500 ml/day for adults, and the water intake is generally balanced with the water discharged by the human body every day. For example, the average daily urine output of adults is about 1500 ml, skin and respiratory tract is about 800 ml, and feces is about 1000 ~ 200 ml, totaling about 2500 ml.

Therefore, normal people need to drink about 1500 ml of water every day besides eating, and about 6 ~ 8 glasses of water can meet the needs of human metabolism.

Since water is so important to human beings, the quality of water that people consume every day is a crucial issue, which is directly related to people's health. There are a lot of records in ancient and modern China and abroad. Whether it is "Changshou Village" or endemic diseases in some areas, the causes are related to local drinking water. Good water brings health, while polluted water brings disease. Therefore, people urgently need to drink healthy water that is not only harmless but also beneficial to human health.
