Step 2 pay attention to sun protection

Because the temperature is relatively high before and after the summer heat, and the weather in the south is often hot and humid, the human body feels uncomfortable. Even sweating can't solve the sleepy heat, but it is easier to get heatstroke. Therefore, heat preservation should first avoid overwork in sultry weather, go out as little as possible, and have less activities. In order to let the moisture in the body go out, try to take a walk in the morning and evening when the temperature is low.

Health experts remind that patients with a history of chronic diseases, especially middle-aged and elderly people, are very likely to have cardiovascular and cerebrovascular accidents. Therefore, middle-aged people should avoid excessive physical exertion, such as running and equipment exercise.

But even so, swimming time is exquisite, it is best to choose in the morning or evening, and it is not suitable for one hour after meals.
