1. Avoid opening windows for ventilation.

In dog days, many people are afraid of the heat, so they close the windows and blow air conditioners indoors. In fact, a humid and stuffy room with poor ventilation can easily lead to heatstroke, and if the air conditioner is turned on without opening the window for ventilation, the air quality will deteriorate, but it will cause disease. Suggestion: Open the window for ventilation more than twice a day, each time 15-30 minutes.

2. Avoid cold air blowing in the opposite direction.

The cold air of the air conditioner, blowing against the cervical vertebra of the air conditioner, makes the muscles of the neck and back chill, causing persistent neck spasm and back pain. Suggestion: The indoor air conditioning temperature should not be lower than 26℃. Don't face the air conditioning directly on your shoulders and back, or put on a shawl.

3. Avoid cold drinks.

Eat ice cream and cold drinks properly to relieve summer heat. Eating too much will hurt your health. Too much cold food into the stomach for a long time will make the blood vessels under the gastric mucosa contract, the mucosal layer become thinner, and mucosal edema and erosion will occur. In summer, the metabolism of human body is fast, and blood vessels are in a state of expansion. Eating ice drinks suddenly will make blood vessels contract rapidly, cause blood pressure fluctuation, and easily induce cardiovascular and cerebrovascular accidents.

4. avoid not sweating all day

Health care should conform to the laws of nature, and sweat when it is time to sweat, because sweating can not only expel toxins from the body, but also regulate body temperature. Suggestion: Go out for a walk at night, sweating slightly is good for your health.

5. Don't rest at noon

Go to bed late and get up early in dog days, but staying up late is not staying up late, it is better to stay up before 24 o'clock. Because of the hot weather, sleep will be affected to some extent. It is suggested that it is best to take a nap if possible, which can also effectively prevent the occurrence of heart diseases such as coronary heart disease and myocardial infarction. Suggestion: Take a nap 15-30 minutes. After a nap, you can exercise a little and drink a glass of water to dilute the blood viscosity.

6. Avoid taking a cold shower directly.

You can't take a bath with cold water in hot summer. After the human body is stimulated by cold water, it will produce a series of stimulating reactions, such as rapid heartbeat, high blood pressure, muscle contraction, mental tension, etc., which will adversely affect the heart and blood pressure. Suggestion: It is best to rest for 30 minutes after exercise, and then take a bath or wipe it with a towel after the body's heat is released. The water temperature should not be too high, and 36℃-39℃ is appropriate.

7. Avoid eating only fruit

In dog days, people sweat a lot, consume a lot, get tired easily and have no appetite. Many people choose to eat some fruits and vegetables. Poor diet, insufficient nutrition and decreased immunity may all lead to diseases.

Suggestion:

① Fruits and vegetables are indispensable: eat more vegetables and fruits rich in potassium, such as bananas, cantaloupes, tomatoes, pumpkins, beans, potatoes and celery.

Drink some soup to stimulate appetite: vegetable soup, broth, fish soup, egg soup, etc. Drinking a small amount before meals can also stimulate appetite.

③ protein must have: eat lean meat, fish, soybean milk, eggs, etc.
