After exercise, although people feel very eager to replenish water, because the body is still in exercise at this time, the pulse and blood pressure will be higher than usual. Drinking water at once will stimulate the heart and stomach, which will make the body more uncomfortable. The correct drinking time is about 10 minutes after exercise, or after strenuous exercise, such as walking slowly, to restore the pulse and heartbeat to normal levels. Before rehydration, the limit of rehydration is no more than 100ml each time, and the interval of rehydration is 10 minutes, so that the body can slowly accept rehydration without a series of uncomfortable reactions. In addition to hydrating, you can also deal with some vitamins and mineral drinks to assist the recovery of physical fitness.
