After the summer exercise, sweaty, drink a cup of cold drinks, is it beautiful?

Be careful! Drinking ice water after high temperature is risky.

Let's take a look at what our heart is doing during exercise: the increase in oxygen demand for muscle tissue, in order to meet the demand for this part of the increase, the heart rate increases accordingly, the heart rate of the heart rate increases, thereby increased the heart of the heart. Increase, increase heart load. Therefore, the stronger the exercise, the greater the heart load.

When the weather is hot, the human body is in a state of relatively high body temperature and relative expansion of the cardiovascular. At this moment, let the body be cold, such as drinking a lot of cold drinks, blowing cold air conditioners, etc. The body is strongly stimulated, which may cause cardiovascular contraction or even spasm. Creating sudden death.

"Patients who drank ice water after strenuous exercise such as playing basketball caused heartbeat and respiratory suspension, and occasionally occurred in our emergency." Ice water, take a cold bath, blow air conditioner. In addition, you must not be "too hard" in summer, you must do your best.

According to his observations, exercise damage in summer is more damage than winter. Because of the hot weather, the human body consumption is large, the dressing is less, the skin is exposed, and the exercise damage also increases.

How to move scientifically in summer? He suggested that trying to avoid the high temperature period of noon, it is best to choose to exercise early or evening. At the beginning and end of the exercise, there must be a gradual adaptation process. If you feel uncomfortable in exercise, do not support it, and say in a timely manner with your companions. Once an accident occurs, call 120 for help in a timely manner, and at the same time ask the surrounding people to ask for help. If there is a doctor present, the chance of rescue success will be greatly increased.

Sweating will consume a lot of water and electrolyte, so hydration is also very important. Before exercise, it should be appropriately replenished; during exercise, it is advisable to make small amounts and continuously replenish hydration; the principle of hydration after exercise is also "a small amount" and should not be too fast.

Summer exercise is easier to lose weight than winter?

I believe many people will think: "Summer sweating more in winter, faster metabolism, and consumption of calories faster." This sounds very reasonable, but in fact, summer sweats are just a way to heat dissipation, and it does not mean that summer is more suitable for weight loss than winter.

In fact, it is better to lose weight in winter. why?

First of all, in different environments, the energy system used by body temperature regulation is different -the body temperature needs to be reduced in summer, and sweat will secrete sweat and increase heat dissipation. Most of the consumption is sugar. It is fat, which is also one of the reasons why it is more suitable for fatting in winter.

Secondly, when our body is in a relatively cold "stress state", the body increases basic metabolism in order to resist the cold, produce additional heat consumption, and when the weather is cold, exercise needs to work harder to consume more calories.

In the end, when it comes to weight loss, we have to mention the weight loss helper of the human body- "brown fat". Brown fat is responsible for decomposing white fat that caused obesity, and converts it into carbon dioxide, water and calories. It can speed up the body's metabolism and promote white fat consumption.

The more brown fat in the human body, the easier it is to lose weight. But this magical fat will decrease with age, but in a cold environment, it will be induced. Studies have found that after 2 hours at the temperature of 19 ° C, brown fat can be initiated to burn white fat, which greatly increases fat burning.

Of course, no matter what season to lose weight, the most important thing is to rely on healthy diet and exercise habits.
