It is suggested that the daily drinking water should be about 1.2 ~ 2 liters. If you sweat a lot after exercise, especially in summer, you can increase it appropriately.
Drinking too much water is easy to "water poisoning". After the human body ingests a lot of water, it must excrete excess water through urine and sweat. However, with the discharge of water, the sodium-based electrolyte in human body will be diluted, and with the decrease of salt in blood, some water will be quickly absorbed into tissues and cells, causing cell edema. At first, there will be symptoms such as dizziness, weakness and rapid heartbeat. In severe cases, there will even be convulsions, confusion and coma.
Because human body fluids are slightly alkaline and pure water is weakly acidic, if you drink weakly acidic water for a long time, the environment in your body will be destroyed. In addition, drinking pure water for a long time will also increase the loss of calcium.
