The coach says you shouldn't drink more water when you exercise. What is the reason? In most cases, when the water in the body decreases, people will feel thirsty, and people will drink water to replenish the lost water. When busy with daily life at home or in the office, the feeling of thirst is a sign of drinking water. However, when you exercise or work in a hot and summer environment, your body may have been dehydrated before you feel thirsty. Therefore, when you exercise, you should replenish water as soon as possible before you feel thirsty. The specific drinking method is as follows.

Drink water before exercise, and drink 300-500ml within15min before exercise. This is to store water for the body. Although you won't feel thirsty when drinking water, when you start sweating, water will be absorbed into your blood. Especially for long-term endurance exercise, it is more necessary to replenish water at this stage.

Drink water while exercising. During exercise, drink 150-250ml of water every15min or at an appropriate time during exercise. Our stomach can empty 1000- 1200ml per hour, so it is most appropriate to replenish water according to the speed of gastric emptying.

Drink water after exercise, and replenish all the consumed water during exercise, plus 25%-50% water, because some of the supplemented water will be excreted in urine. This means that you need to replenish at least 500 ml of water, and if you sweat a lot, you need to increase the amount of water. To judge how much water you have lost after exercise, you can compare the weight difference before and after exercise.

In addition, the sweat discharged during exercise contains sodium salt. When you sweat, your body will lose some sodium. Most people can supplement their exercise by drinking a little sports drink or eating. If the day's exercise is particularly sweaty, it may lead to excessive sodium loss, which may lead to cramps. Therefore, in this case, sports drinks containing sodium can effectively make up for the loss of sodium caused by exercise.
