Drinking too much water will take away useful trace elements in the body, which will easily lead to a large loss of salt, dilute blood and even cause shock, which is also commonly known as water poisoning. The cause of "water poisoning" is related to the loss of salt in the human body. It turns out that people lose not only water but also a lot of salt after sweating a lot in hot weather. 1 liter of sweat contains nearly 3 grams of salt. If you sweat 5 liters for half a day, you will lose nearly 15 grams of salt. After sweating, if you drink a lot of boiled water at a time, the water will be absorbed by the gastrointestinal tract and then excreted through sweating, and some salt will be lost with sweating. In this way, the salt in the blood is less and less, the water absorption capacity is reduced, and some water will be absorbed into the tissues and cells quickly, which will make the cells edema, and people will feel dizzy and have symptoms of "water poisoning".
