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 electrolytes with sweat, the concentration in the blood will also rise, which will increase the burden of cardiovascular operation. So it should be replenished at the right time so that it will not affect the operation of cardiovascular function. At this time, you can drink light salt water to replenish the substances lost due to sweating in time. Sports drinks are recommended to be consumed intermittently before, during or after exercise.
