Drinking light salt water can replenish electrolytes, but don't mix them at will. After all, this thing is not soup. Add as much salt as you want. Generally speaking, the concentration of physiological saline needed by mammals (including humans) is 0.9%, that is, the ratio of 1000ml of water is 10 g or 9 g of salt (about one tenth of that of ordinary spoons), and the temperature should be controlled at 20℃~ 30℃.
