How to prevent heatstroke and cool down in hot weather in summer?

In recent years, environmental protection workers, construction workers and other field workers have frequently died of high temperature heatstroke, which has aroused social concern. With the approach of this year's summer heat, we should sort out the laws, regulations and technical standards of China's summer heat, popularize the knowledge of occupational heatstroke prevention, and improve the whole society's understanding of workers' occupational health.

What is hot weather? High temperature weather refers to the weather where the highest temperature of meteorological stations affiliated to meteorological departments above the municipal level is above 35℃.

Measures to prevent wind and cool down in summer

1, drink water on time

The most important thing for heatstroke prevention in summer is to replenish water in time. In order to consume enough water in the body, it is recommended to drink more boiled water, salt water and tea, and less drinks. Because drinks contain a lot of saccharin and electrolytes, drinking too much will have a bad influence on the gastrointestinal tract.

2. Eat more vegetables and fruits with high water content.

Vegetables with high water content include wax gourd, cucumber, tomato, towel gourd and bitter gourd. Fruits with high water content include watermelon, lemon, orange and pear. The hot summer is the moment when the human body's resistance is weakest. At this time, we should eat more fruits and vegetables, supplement vitamins and water, improve immunity, prevent diseases, eat more meat, such as chickens, ducks, geese and fish, and promote the metabolism of the body.

3. Don't do strenuous exercise

Summer is the highest temperature of human body. At this time, stop resting immediately after strenuous exercise, blood pressure will drop, and symptoms such as palpitation, dyspnea, dizziness, pale shock and fainting will appear. In order to prevent this incident, we must do some exercise after strenuous exercise and have a rest after breathing and heartbeat slowly return to normal.

4, indoor and outdoor temperature difference should not be too big.

The temperature difference between indoor and outdoor should not be too large, and it is most appropriate to keep it within 5 degrees. Because the human body itself has the function of regulating temperature. This is because, even if you wait for a long time under air conditioning, if the temperature difference between indoor and outdoor is too large, it will suddenly become cold. If the heat suddenly forms a huge contrast, the adjustment function of the human body will be disordered.

5. Don't take a nap for too long.

You will feel tired in summer. People are very sleepy and weak. Taking a nap at this time is the best way to get rid of it, but I don't know when I will fall down. Taking a long nap will deeply inhibit the central nervous system of the brain, make the capillaries of the brain tissue close for too long, reduce the blood flow of the brain, gradually slow down the metabolism of the human body, and become more tired after waking up. But you can't stay up late, and you should ensure adequate sleep quality.

6. Go out and prepare sunscreen.

It is best not to go out in summer, and it is best not to go out before the coolest night. If you need to go out, you should take protective measures. Such as parasols, tea cotton, sunglasses, etc. It is best to apply sunscreen.

7. I want to bring summer cold medicine.

Drugs for relieving summer-heat include musk oral liquid, 10 drop of water, Ren Dan, cooling oil, essential balm, plague, heatstroke, etc. In order to prevent accidents, please take some of the above drugs. In addition, drink more Chinese medicine in summer to prevent heatstroke.

What should I do if I find someone suffering from heatstroke?

1. When you find yourself and others with signs of threatened heatstroke and mild heatstroke, the first thing to do is to quickly evacuate the high temperature environment that causes heatstroke and choose a cool and ventilated place. First of all, you should quickly move the heatstroke patient to a cool and ventilated place. Untie your clothes, take off your shoes, lie flat and lower your head to keep the patient breathing smoothly.

2. Wipe the whole body with cold water or 50% alcohol, the skin will turn red, the blood vessels will dilate, and it will promote clearing away heat and cooling down.

Patients who can drink water should be encouraged to drink more salty soft drinks. People who can't drink drinking water should be sent to hospital for treatment in time.

4. You can apply cool oil, wind oil essence, etc. Tofu on your forehead and side, you can also take traditional Chinese medicine, such as Ren Dan, 10 drop of water and musk purified water. When blood pressure drops and collapses, you should lie flat immediately and inject normal saline into the hospital in time.

5. In case of severe heatstroke, first aid should be given immediately or sent to the local hospital for declaration in time, the cause of heatstroke should be investigated, and preventive measures should be taken actively to prevent heatstroke accidents from happening again and again, so as to ensure the health of employees during the dry summer construction.

In order to prevent the danger caused by high temperature operation, all departments should strengthen the training and education of high temperature heatstroke workers. In order to improve the effect of safety training, tools such as multimedia safety education toolbox can be introduced to let employees have a deeper understanding of the hazards and preventive measures of high temperature operation. In this way, we can have an interesting lecture on construction matters needing attention. Let the waiter automatically acquire all kinds of safety knowledge needed for construction in the state of rest and entertainment.
