How much water does the human body need every day?

Nutrition experts point out that drinking water is like taking in calories, "replenish as much as you need", and drinking too much water can cause electrolyte imbalance (loss of sodium and potassium ions), easy loss of water-soluble vitamins (such as B group and C) and other problems.

Scientific research shows that the human body loses about 1800 to 2000cc of water every day through urine, sweat or skin evaporation, so it is said that healthy adults need to replenish about 2000cc of water every day. But 2000cc of water is not necessarily obtained by drinking water, and the water in food should be counted together. In fact, the various foods we eat every day contain a lot of water. For example, most vegetables and fruits are more than 90% water, and eggs and fish also contain about 75% water. Roughly speaking, we can get at least 300 to 400cc of water from food or soup when we eat a meal. Therefore, after deducting the 1000-1200cc of water ingested from food during the three meals, we only need to drink 1000-1200cc of boiled water every day, 2 cups in the morning and 2 cups in the afternoon on average, to complete the basic work. However, the amount of water required depends on each person's environment (temperature, humidity), amount of exercise, physical health, and food intake, and there is no standard value.
