01

Wash a cold bath

There are air -conditioned rooms in 24 hours

As soon as the weather was hot, I couldn't wait to be in the air -conditioned room for 24 hours. Over time, air -conditioning lungs and air conditioners have come out. If the air conditioner is not cleaned for many years, it will accumulate a variety of healthy germs and mites. Once inhaled, it may cause varying degrees of respiratory infections, and even cause "air -conditioning lungs" to occur with quality lung diseases.

Tips:

1. Blowing the air conditioner is worse than sweating, letting the body sweat naturally.

2. Do not frequently enter the air -conditioned room. When sweating, you should wipe the sweat first and then blow the air conditioner.

3. The time for using the air conditioner should not be too long. Generally, the air conditioner is opened for two or three hours, and the window should be opened for half an hour.

4. If you can't leave the air conditioner if you need it, you must protect the cervical spine, shoulders, knees, ankles, etc., let alone blow the body, you can install the air -conditioning windshield.

The scorching sun is shirtless

Loubo said that the pores on the back of the human body in the summer are opened. If it is exposed to ultraviolet rays for a long time, in addition to sunburn, it may also cause edema, and severe cases can even cause kidney disease.

Tips: Try to avoid outdoor activities as much as possible, especially avoiding the strongest in the morning to 2 pm. When you have to work, pay attention to heatstroke and cool down, take a cool rest for a while every two hours, and wear hats, drink plenty of water, and bring cool heat cooling drugs such as cool oil.

Thirsty irrigation

As soon as the weather is hot, sweaty, and easy to thirst, many people raised the cup and irrigated. Although the thirst was quenched, the heart suffered. Huang Li, director of the Chinese and Western Medicine Internal Medicine of China -Japan Friendship Hospital, introduced that appropriate hydration in summer can replenish water and reduce blood viscosity. Burmenting people with symptoms such as chest tightness, shortness of breath, and dyspnea.

Especially for people with poor heart function, the weather is hot, and the human blood vessels are expanding. Suddenly drinking water can cause the blood vessels to shrink rapidly, cause insufficient blood supply to the cardiovascular and cerebrovascular, and cause angina pectoris and even heart failure.

Tips: Drinking water in the summer should be a small amount, about 200 ml at each time. Don't wait until you are thirsty and drink water.

05

Cold drink without litter

Cold drinks are a must -have artifact to relieve heat, but if long -term cold drinks do not leave their mouths, the gastrointestinal and intestines will not be able to stand it. Don't drink cold drinks as soon as it is hot. After drinking cold drinks, the first impact on us is the stimulus of the stomach, because the esophagus is just passed by sexually. What really affects the gastrointestinal tract. Cold things may cause blood vessel contraction of the gastric wall, cause the blood supply to the gastric mucosa, which is obstacle, more likely to cause gastric mucosal damage, cause chronic gastritis, etc.

Some people are more sensitive to cold. After the cold drinks enter, they will increase the intestinal motility, cause diarrhea, etc. There are also some cold drinks, if not particularly clean, it will also cause some infectious diseases in the digestive tract.

People with cardiovascular and cerebrovascular diseases should also pay attention to, because eating cold drinks can cause blood vessel contraction, and sometimes it can induce the occurrence of cardiovascular and cerebrovascular diseases.

Tips: It is better to drink hot tea. Drinking hot tea in summer can not only quench thirst, but also promote sweat and heat dissipation.

06

Don't sleep in the air -conditioned room all night

Many people like to sleep in the air -conditioned quilt in the summer. Lu Lu, the chief physician of Shaanxi Provincial Hospital of Traditional Chinese Medicine, said that the temperature difference between indoor and outdoor is too large, which will cause the pores of the whole body to close, the heat in the body is difficult to distribute, and it will cause insufficient brain blood supply due to the rapid contraction of the brain blood vessels. People are more likely to attack "hot strokes".

In addition, the opening of the air conditioning window will cause indoor air turbidity. If you sleep all night in such an environment, it will be unfavorable to the human body.

Tips: Don't be too low in the temperature of indoor air conditioners, don't use the air conditioning time for too long.
