How to prevent it?, Why is heat stroke fatal? Weather with high temperatures exceeding 40 ℃ | Heat stroke | High temperature

Recently, a large area in the north has started a barbecue mode, with the highest temperature in many places exceeding 40 ℃. At 06:00 on the 18th, the Central Meteorological Observatory continued to issue a yellow warning for high temperatures. It is expected that some areas in southeastern Inner Mongolia, western Liaoning, and southern Xinjiang Basin will have a maximum temperature of 37-39 ℃, with some areas reaching over 40 ℃.

Continuous high temperatures have led to cases of heat stroke in some areas. Recently, a middle-aged woman in Beijing experienced multiple organ failure due to heat stroke. Despite nearly 7 hours of rescue, she unfortunately passed away. As a high-temperature killer, what is heat stroke? How to prevent heat stroke when high temperatures exceeding 40 ℃ strike? Listen to what the doctor says.

What to do if there is a premonitory heat stroke phenomenon?

Under high temperatures, physiological changes occur in the body's temperature regulation, water and salt metabolism, digestion, nervous system, urinary system, and circulatory system. When the changes exceed the human body's tolerance range, it is easy to suffer from heatstroke.

Dr. He Mingyi, attending physician at the Emergency Department of Xuanwu Hospital of Capital Medical University, reminds that in a high-temperature environment, if symptoms such as dizziness, headache, limb weakness, thirst, sweating, palpitations, chest tightness, lack of concentration, and uncoordinated movements occur, but the body temperature is normal or slightly elevated, it is a precursor to heatstroke.

He Mingyi stated that if there is a premonitory heat stroke phenomenon:

Firstly, it is necessary to leave the high temperature, high humidity, and enclosed environment as soon as possible, and then go to a ventilated and cool place;

If the condition is not too severe, you can drink some cool drinks in moderation, such as diluted salt water, salted tea, or salty cool drinks;

You can use a cold towel to wipe and cool down, and some patients can improve their symptoms;

You can prepare some room temperature mung bean soup at home, which also has the effect of relieving heat and cooling down.

How to prevent heat stroke?

Experts introduce that severe heat stroke can be divided into three types based on clinical manifestations: heat spasm, heat failure, and heat stroke. Among them, heat stroke is the most dangerous, accompanied by multiple organ damage. In severe cases, it can be life-threatening. The prominent features of heat stroke are sweatlessness, high fever, and blurred consciousness.

Zhu Huadong, director of the emergency department at Peking Union Medical College Hospital, said that the public should pay attention to weather changes and try to avoid environments with high temperatures and humidity. At present, there are no special drugs for treating heat stroke. "If a patient is found to have special circumstances, such as unclear thinking, they should be moved to a cool place, their clothes should be unfastened, their body should be wiped with warm and cool water, or blown with an electric fan, and promptly sent to the hospital."

The climate factors of high temperature and humidity, as well as high-intensity physical activity, are the main risk factors for heat stroke. June to September is the period of high incidence of heat stroke.

Zhu Huadong introduced that not only outdoor workers are high-risk groups, but also those who have been working indoors may be caught. "In a closed environment with high temperatures, coupled with some elderly people suffering from underlying diseases such as body temperature and heat dissipation problems, non exertional heat stroke can occur. In addition, sitting during the postpartum period and closing doors and windows in the hot summer weather can also easily lead to heat stroke."

How to prevent "air conditioning diseases"?

The high temperature is unbearable, and many friends like to stay in air-conditioned rooms to avoid the heat. However, long-term exposure to air-conditioned environments not only makes it easy to feel dizzy and headache, but also causes symptoms such as lack of appetite, upper respiratory tract infections, and joint soreness, collectively known as "air conditioning disease", especially for the elderly, children, and women.

Xiao Han, Chief Physician of the Respiratory Department at Xuanwu Hospital of Capital Medical University, suggests:

Try to choose long sleeved clothes in air-conditioned rooms, and do not blow the air conditioning directly when sweating profusely;

Pay attention to ventilation and breathability when blowing air conditioning;

Staying in an air-conditioned room for a relatively long time, pay attention to replenishing water;

The most suitable temperature is 26 degrees. Choose a low-grade wind and do not blow directly, especially when sleeping;

If you feel cool enough, you can stop or intermittently stop the air conditioning for two to three hours.

Experts remind that in hot weather, it is important to drink more water, reduce high-fat diets, and increase the intake of foods rich in high-quality protein and vitamins, such as eggs, milk, vegetables, and fruits. It is also important to control the consumption of high sugar, alcoholic beverages, and chilled foods.

If someone is suffering from heatstroke, it is incorrect to quickly transfer them to an air-conditioned room with low temperature. It is most appropriate to transfer the patient to an environment between 22-25 degrees Celsius.
