You can drink water immediately after exercise, but not in large quantities. Sweating needs to be replenished in time, and a small amount of water can be added.

After strenuous exercise, people often sweat a lot to take away heat, and sweat will also take away some salt in human blood. If you drink a lot of water immediately, it will increase the discharge of sweat, make more salt loss and increase the blood circulation, thus increasing the burden on the heart. Therefore, people should not drink water immediately after strenuous exercise.
