Dr. Yong Cheng, head of nephrology department of Shenzhen Second People's Hospital, told people that, generally speaking, the amount of water people drink every day should at least be balanced with the water consumption in their bodies. The amount of urine excreted by the human body in one day is about1500ml, and the water evaporated from feces, breathing or skin is about 2500ml, while the water that the human body can replenish from food and metabolism in the body is only about1000ml every day.
Usually, how much water everyone needs to drink varies according to the amount of activity, the environment and even the weather. Normal people drinking too much water will not have much impact on their health, but may cause an increase in urination and inconvenience in life. However, for some special people, we must pay special attention to the amount of water to drink. For example, patients with edema, heart failure and renal failure should not drink too much water, because drinking too much water will increase the burden on the heart and kidneys and easily lead to aggravation of the disease. For patients with diseases such as heatstroke, cystitis, constipation and dry skin, drinking more water can play a certain role in relieving the disease. In addition, people should also drink plenty of water when they have a cold and fever, because rising body temperature will cause water loss, and drinking plenty of water can promote the body to dissipate heat and help patients recover. And pregnant women and people who exercise a lot consume much water and should drink more water.

The sources of human water mainly include dietary intake, drinking water and endogenous water produced by metabolism. The water content in three meals a day is 700 ~1000 L per day, the water intake through drinking water is about 1200l per day, and the endogenous water is 300l per day. The discharge of water is mainly divided into four parts, namely, the daily discharge of kidney (urine) 1500l, the daily discharge of skin (evaporation)/500l, the daily exhalation of lung/350l and the daily discharge of feces150 l. Under normal circumstances, the intake and discharge of water are in a state of dynamic balance. The integrity of renal function is the basis of maintaining water in the body. When renal failure occurs, this dynamic balance is broken, causing a series of diseases. The most common clinical manifestation is water and sodium retention, so it is necessary for patients with renal failure to control the balance between water intake and discharge.
