Do not drink water immediately after exercise, if the intensity is not large, not long, the ambient temperature is not high in the case of exercise, the body will produce less heat, will not produce a large amount of sweat and loss of inorganic salts, so sweating is relatively small, rest a few moments after drinking some boiled water can be. If in the case of more sweating, after exercise should be appropriate to drink light salt water. Because the body will lose a lot of water and sodium with sweat, blood concentration, blood viscosity increases, blood flow slows down, which can lead to cardiovascular disease. So it is important to replenish water at the right time so that the cardiovascular function will not be affected. At this time, you can drink light salt water to replenish the substances lost due to sweating in a timely manner. Sports drinks are recommended to be consumed intermittently before, during or after exercise.
