I have seen many people pick up a large bottle of water and drink it down after exercise. Is this the right way? In fact, after exercise, water is particularly particular, drink wrong, not only can not quench thirst, but will bring harm to the body. After exercise, sweat, water and electrolytes (mainly sodium and chloride ions, as well as a small amount of potassium and calcium) are lost in large quantities. If water and corresponding minerals are not replenished in time, dehydration and other abnormal manifestations may occur.
