Doctors remind people that in hot summer, the metabolic rate of the body will be higher than that in other seasons, which means that more nutrients will be consumed, and if it is not replenished in time, it will inevitably cause damage to the body.

First of all, the ambassadors were sweating because of the hot weather. Ordinary people can excrete more than 3 liters of sweat by doing a lot of 1 hour at 30 degrees Celsius. If you don't replenish water in time, when your body is dehydrated to about 1/4 of your body weight, you will have symptoms such as fatigue, anorexia, dizziness, nausea, muscle spasm and even fainting.

So, how to be correct? Experts remind that although it depends on different fitness intensity, you should drink slowly, the water temperature should not be too low, and it is best to choose boiled water or mineral water.

For bodybuilders who don't exercise for more than 1 hour and have low exercise intensity, the amount of sweating will not be great, as long as they drink 1-2 glasses of water before and after exercise.

If the fitness time exceeds 1 hour, drink 1 glass of water every 20 hours before and during exercise. Drink 1 glass of water, and drink 1-2 glasses of water after exercise, each cup is -400 ml.

In addition to the increase of water loss during exercise, many minerals will also be lost with sweat. People eat more fruits to increase the intake of these minerals, because fruits are rich in minerals such as potassium, sodium, chromium, zinc and selenium. In addition, vitamin supplement can not be ignored, because B vitamins directly participate in the body's energy production, so the exercise ability will be improved. This requires bodybuilders to eat more milk, green vegetables, red vegetables, red meat, marine plants, mushrooms and so on.

There is a limit to drinking cold drinks.

There are many kinds of cold drinks, which are full of temptations for everyone. However, the body's yang is outside and yin is inside, and the secretion of gastric juice is relatively reduced, and the digestive function is low, so it is forbidden to drink too much. In addition, don't eat too much cold drinks after sweating, especially for some chronic patients. Eat cold drinks selectively. Such as coronary heart disease, asthma, chronic bronchitis, should not eat frozen food; Those with gastric ulcer and hyperacidity should not eat more sour cold drinks; Diabetic patients should not use sugary drinks. It should also be noted that drinking drinks can not replace drinking water, and it is better to drink tea to relieve summer heat. Hot tea is an ideal drink in summer.

Sweating is not as active as taking the initiative.

Passive sweating is harmful to human body, such as sweating caused by hot weather and irritability. If you are in poor health, this sweating will do some harm to the human body. Active sweating is sweat produced by active exercise of human body. This kind of sweating itself is beneficial to keep the temperature in the body and emit heat.

The more exercise, the better.

When the human body moves to a certain extent, it will reach a stimulating point. But if you continue to practice, you may feel tired and have physical exhaustion, which is unfavorable to people's physical quality. So, when you are happiest and most comfortable, don't increase the amount of exercise casually. At this time, you need to gradually reduce or stop exercising.

Lose weight in summer.

Girls who love beauty must not interrupt their fitness plan because of the hot weather in summer. If it is suddenly interrupted, the muscles will become very relaxed, which will make the previous training fall short. The activity time should be one and a half hours as far as possible, with running, aerobics, swimming and outdoor activities as the main activities. But in order to achieve good results, it is best to go to the gym for systematic training.

During exercise, pay more attention to diet. Before exercise, the diet should be mainly rice and flour. After exercise, we should give priority to protein and eat more eggs, fish and lean meat. During exercise, it is best to drink 6 to 8 glasses of water in a small glass every day.
