In the process of fitness and exercise, the amount of perspiration of people increases obviously. Especially in hot summer, I sweat profusely after every fitness exercise. People who exercise are prone to dehydration if they don't pay attention to reasonable hydration. Dehydration makes people lose their physical strength, and long-term dehydration will affect people's health. Therefore, in the process of fitness exercise, it is very important to replenish water reasonably.

First of all, drink about 500 ml of boiled water about two hours before the start of fitness or exercise, and the same is true in summer. Don't neglect this step because of the hot weather. Supplementing water before exercise can improve the body's heat regulation ability and help to discharge excess water from the body.

In the process of exercise, it is best to supplement sugar and salt water, which can quickly replenish the water lost in the human body. Don't gulp water when hydrating. On the contrary, take a sip and drink slowly, and add a small amount many times. Also, don't drink cold drinks, especially in hot summer. Drinking cold drinks is really refreshing, but drinking cold drinks during exercise is very harmful to your health. During exercise, the water temperature should be kept between 15 and 20 degrees Celsius, otherwise it will easily cause gastric dysfunction and stomach cramps.

Many fitness athletes like to drink sports drinks. Carbohydrates contained in sports drinks can delay athletes' fatigue and increase insulin in the blood after exercise. However, when choosing sports drinks, fitness operators should be careful not to choose hypertonic drinks, because it is easier to lose water in furniture, and athletes will feel more and more thirsty and can't replenish water at all. Friends who love fitness must replenish water scientifically and reasonably to provide a solid and reliable foundation for fitness.
