1. After running, you will sweat a lot. When sweating, a lot of electrolyte will be lost.

2. If you drink a lot of water just after running, it will dilute the electrolyte, resulting in a decrease in electrolyte concentration.

3. Whether the electrolyte concentration is normal is very important to maintain the normal metabolism of human body.

4. When the electrolyte concentration is too low, it will affect the functions of the heart, nervous system and other body systems.

5, don't stop immediately after running, it is best to walk slowly for a few minutes, if you stop immediately, it will affect the function of the heart.

6. If you drink a lot of water after running, a lot of liquid will increase the burden on your heart and affect your health.

Correct hydration methods before and after exercise:

If you engage in strenuous exercise, you need to take in more water to prevent dehydration. This is not only to prevent your body from collapsing due to excessive water shortage, but also to ensure that your body is always in the best exercise state.

2~3 hours before exercise, you should drink 2~3 cups (500~700 ml) of water to ensure that your body is not short of water before exercise. If you are always saturated with water, you don't need to take in too much water, because your body can't store too much water. However, if it is summer, the weather is hot and the consumption is large, the frequency of water replenishment should also be increased appropriately.

During exercise, the metabolism of water is accelerated, and a lot of water is lost, so water should be replenished every 15~20 minutes, and 0.5~ 1 cup (120~230 ml) of water should be drunk every time. But when the exercise time is too long, more than 60 minutes, or when you are engaged in high-confrontation sports, then you need to drink sports drinks.

Because strenuous exercise leads to accelerated electrolyte metabolism in the body, a large number of electrolytes are lost with sweat. Therefore, water, sugar and electrolyte should be supplemented together. If you don't pay attention to rehydration during exercise, it will lead to dehydration during exercise.

Sports drinks generally contain sugar and electrolyte, and the composition and content of various nutrients can adapt to the physiological characteristics and special nutritional needs of physical exercisers. Many athletes drink sports drinks between games.

In addition, the fluid infusion during exercise should generally not exceed 800 ml, and must be small for many times to avoid a heavy burden on the gastrointestinal tract and cardiovascular system caused by a large amount of fluid infusion at one time. For high-intensity exercise at high temperature, the infusion volume per hour should be greater than 300 ml.

It should be noted that sports drinks are not suitable for everyone. For people with hyperglycemia or diabetes, be extra cautious when drinking.

In addition, people with high blood pressure, poor heart function or kidney function should not drink a lot, so as not to increase the burden on the heart and kidneys. In addition, it is generally not recommended to drink sports drinks containing carbon dioxide gas before and during exercise, which will cause flatulence and is not good for exercise.
