Normal people have a mechanism to regulate the body to maintain water balance, to avoid the accumulation of water in the body. When drinking more water, the kidneys will also increase the amount of drainage to maintain water balance. The accumulation of water in the body can cause edema and increased blood pressure, which can be harmful to organs and tissues, such as heart failure and cerebral edema.
