The southern summer gives people the feeling that they will sweat when they breathe.
Recently, a middle-aged man in Huizhou died of severe heat stroke. When he was admitted to the hospital, the man's body temperature was close to 42 ° C, the heart rate reached 139 beats / min, and the respiratory rate was 28 times / min, far exceeding the normal person's 12 to 20 beats / min.
According to reports, the man had been outdoors for a long time, did not replenish water and electrolytes in time, coupled with sun exposure, and eventually suffered from severe heat stroke.
<h1 class="pgc-h-arrow-right" data-track="4" >, why do people suffer from heat stroke</h1>
Summer has the characteristics of high temperature, high humidity, strong heat radiation, etc., which can easily change the human body's water metabolism, body temperature regulation and circulatory system, affecting the physiological functions of the digestive, nervous and urinary systems. If the body cannot adapt, it is easy to cause physiological dysfunction, resulting in abnormal increases in body temperature and heat stroke.
In a high temperature environment, many factors will affect the self-regulation of body temperature, such as high air humidity will prevent sweat evaporation and affect body heat dissipation. In addition, factors such as age, dehydration, fever, obesity, illness, overwork, and mental stress are common triggers for heat stroke in summer.
<h1 class="pgc-h-arrow-right" data-track="41" > second, symptoms before heat stroke, do not be careless</h1>
According to the different symptoms, heat stroke can be divided into three stages: aura heat stroke, mild heat stroke and severe heat stroke.
Aura heat stroke: This is the initial stage of heat stroke, generally there will be dizziness and nausea, thirst and sweating, chest tightness, shortness of breath, general weakness and other symptoms, at this time to the shade of the place to rest, replenish water, discomfort symptoms can be alleviated by themselves.
Mild heat stroke: On the basis of the symptoms of threatened heat stroke, it will also be accompanied by symptoms such as shortness of breath and sweating, and the body temperature can reach more than 38 ° C, but the hands and feet are unusually cold. At this stage, it is also necessary to stay in the shade in time, replenish water in time, rest enough, and can return to normal.
Severe heat stroke: This is the most severe stage of heat stroke, which can produce heat cramps, heat exhaustion and heat stroke, and the body temperature can reach more than 40 ° C, and there will be symptoms such as fainting and unconsciousness. Once you have severe heat stroke, you need to be sent to the hospital immediately for rescue.
<h1 class="pgc-h-arrow-right" data-track="42" > Third, correct first aid is important</h1>
First aid after heat stroke is very necessary, especially timely and appropriate treatment, can help heat stroke patients quickly relieve the heat, but keep in mind that there are two practices after heat stroke that are not advisable!
First of all, do not drink Huoxiang zhengqi water after heat stroke. There is no "treatment of heat stroke" in the indications for Huoxiang Zhengqi water, and the adverse reactions and contraindications of the drug are not obvious, and it is not scientific to take it to heat stroke patients at will. In addition, Huoxiang Zhengqi water contains 40% to 50% alcohol, and taking it after heat stroke may aggravate the degree of dehydration in the body, and it cannot alleviate the discomfort of heat stroke at all.
Secondly, do not pinch the patient among the people. Pinching is a more dangerous behavior, which may make the breathing of heat stroke patients more unsmooth, and the potential risk is relatively large, and it is not recommended to do so.
When encountering heat stroke patients in life, the correct first aid method should keep 3 words in mind.
move
Quickly move the heat stroke patient to a cool and ventilated place, let the patient lie flat, unbutton the clothes and belt, and use fans and fans to fan the patient.
wipe
The body of a heat stroke patient may be wiped with diluted alcohol or cold water, and an ice towel or ice pack may also be placed on the patient's neck, armpits, and the root of the thigh, such as the aortic vascular area, in order to help heat dissipate heat in the heat stroke patient.
wear
Let people with heat stroke take antipyretic drugs and drink more light salt water, with the goal of replenishing lost body fluids and electrolytes.
If the symptoms of heat stroke are severe or the patient is unconscious, after simple treatment, he should dial 120 in time and send it to the hospital for rescue.
<h1 class="pgc-h-arrow-right" data-track="44" >4. How to prevent heat stroke</h1>
Hot summer weather is the norm, but this summer is especially hot, how can we prevent heat stroke in our lives? Guangdong Cd-operative Center for Disease Control and Prevention gave the principle of "three to three don't" to prevent heat stroke, collect it quickly!
1. Three points
To drink more water, especially when working and exercising in a high temperature environment, you should drink 500 to 1000ml of cool white every hour. If it is a long-term exposure to the sun, you should also drink some light salt water or sports drinks containing trace elements such as potassium and magnesium to replenish the lost electrolytes.
Eat lightly and rest well. In high temperature weather, the daily diet should be light, it is recommended to eat more fresh fruits and vegetables, do not eat too much greasy fried food, and ensure adequate sleep.
To choose indoor activities, if the indoor temperature is higher than 35 ° C, you can consider using air conditioning to cool down, but pay attention to the rational use of air conditioning, timely window, ventilation and ventilation.
2, three do not
Do not drink drinks high in sugar or alcohol, frozen drinks can cause stomach cramps and should not be drunk more.
Don't go out during high temperatures, especially from noon to two o'clock in the afternoon, when the sun is at its best. It is generally recommended to go out in the morning or evening, and choose to move or rest in the shade whenever possible. In addition, when going out, it is best to choose light, loose, breathable, light-colored clothing, and carry sunshade tools and anti-heat drugs with you.
Do not ignore your own health, if you have dizziness, nausea and other symptoms of heat stroke in a high temperature environment, you should immediately stop activities, transfer to a cool place to rest, and replenish water at the same time. If symptoms do not resolve, you should seek medical attention promptly.
Recently, news about "summer heat stroke" and "high temperature and heat death" has frequently appeared in our field of vision, especially on the other side of the ocean, which is more serious. Although the situation in our country is acceptable, but still let many people can not stand, we must do a good job of heat prevention measures, pay attention to drink more water, light diet, and full rest!
