Prevent heat stroke in summer
Aware
The sun is scorching and the temperature is soaring, and preventing heat stroke has become a top priority.
Today we're going to talk about heat prevention.
What is heat stroke?
Heat stroke refers to an acute disease with central nervous system and/or cardiovascular system disorders as the main manifestations caused by heat balance or water and electrolyte metabolism disorders in the body under the environment of high temperature, high humidity and strong heat radiation.
What are the conditions that are prone to heat stroke?
Excessive ambient temperature, high humidity, low wind speed, excessive intensity of labor or exercise, excessive fatigue, lack of sleep, weakness, obesity, etc. are all easy to induce heat stroke.
What kind of season and
Are people more susceptible to heat stroke?
Heat stroke is more common in the summer months (June to August). When both temperature and humidity are high, the chance of heat stroke is also higher.
Infants and young children, people over 50 years old, people who are overweight or have chronic diseases such as diabetes and cardiovascular and cerebrovascular diseases, people who are in strenuous activities or outdoor exposure to work in hot weather, and people who drink alcohol or take people who affect the body's heat dissipation or sweating (such as antihistamines, anticholinergic drugs, etc.) are all more likely to suffer from heat stroke.
Due to the nature of the work and the requirements of the production process, it is recommended to take comprehensive control measures for the hazards of high temperature, reduce the high temperature contact time of workers, strengthen the protective measures for workers working in high temperature and hot weather, and make emergency preparations for heat stroke.
Heat stroke
What should we do about emergency relief?
If someone close to you suddenly suffers from heat stroke, you can use these four steps of first aid:
01
Shift
First of all, the patient should be quickly transferred to a cool and ventilated location (such as a corridor, corridor, under the shade of a tree, etc.) or an air-conditioned room, away from the high temperature environment, and at the same time untie the patient's clothes, raise the feet to make him lie flat to rest, and if the patient vomits, let him lie on his side to ensure that his breathing is unobstructed;
02
"Dressing"
If conditions permit, ice cubes can be wrapped in a towel and applied to the patient's neck, armpits, and groin;
03
"Drink"
If the patient is conscious, he can let him drink some sports drinks or cold boiled water with a little salt, be careful not to drink too much, to prevent vomiting, abdominal pain and other symptoms, or take traditional Chinese medicine such as Rendan, Ten Drops of Water, Huoxiang Zhengqi Water, etc.;
04
"Rub"
Wipe the patient's body repeatedly with cold water or ice water, fan to cool down, measure body temperature every 10 minutes, and stop all cold compresses to cool down once the body temperature is lower than 38°C, so as not to cause hypothermia.
If there are uncomfortable symptoms such as dizziness, weakness, nausea, etc., you should immediately get out of the high temperature environment and cool down as soon as possible, and those with serious conditions should go to the hospital for treatment immediately.
While waiting for rescue, it is necessary to carry out rapid, effective and continuous physical cooling, knowing that if the body temperature cannot be lowered within 30 minutes after the severe heat stroke is unconscious, it is very dangerous. If you are transported to the hospital by yourself, you should actively take physical cooling measures such as cold compresses during transportation to buy time to reduce damage and protect vital organs.
TIPS:
Get out of the misunderstanding and prevent heat stroke without stepping on thunder
Myth 1
People who suffer from heat stroke have a high body temperature
The truth:
People with heat exhaustion may have cold and damp skin. The patient has a drop in blood pressure, a fast and weak pulse, rapid and shallow breathing, mild dehydration, and a slightly elevated or normal body temperature.
Correct Approach:
At this time, the patient still needs to cool down, and should immediately drink cool non-alcoholic beverages, appropriately cool down physically through wet compresses, baths, etc., change into light and loose clothes, and fully rest.
Myth 2
Have a bottle of cold beer or cold Coke, pour it down, quench your thirst, one word "cool"!
The truth:
Drinking alcoholic beverages and a lot of sugar cannot achieve the purpose of replenishing water to the body, and may also lead to dehydration, which is commonly known as "the more you drink, the thirstier you get". In addition, drinking ice-cold beverages can also cause stomach cramps.
Correct Approach:
Drink at least 2 to 4 glasses (500 to 1000 mL) of cold or light salt water every hour, especially during strenuous exercise or physical exertion. Of course, if you need to restrict your fluid intake and need a low-salt diet due to certain medical conditions, you should consult your doctor.
Myth 3
It's too hot, just eat some fruit
The truth:
In hot weather, it is necessary to consume enough calories, especially protein, and only fruits are not enough.
Correct Approach:
Eat less high-fat and high-fat foods, and try to eat as light as possible. However, it is important to consume enough calories and supplement with high-quality protein, vitamins and calcium.
Myth 4
Blowing an air conditioner is not healthy, but blowing a fan can prevent heatstroke
The truth:
Electric fans do promote heat dissipation, but once the ambient temperature rises to 32°C and above, the effect against heat is minimal.
Correct Approach:
In hot weather, try to stay indoors with air conditioning, in addition to home, shopping malls, supermarkets, libraries and other public places with air conditioning are also a good choice to escape the heat. You can also use cool water to cool your body. For the "cooked" wives (husbands) at home, if they cook for a long time, they should pay special attention to drinking plenty of water, and often leave the kitchen to ventilate, or find a way to let the cold air of the air conditioner enter the kitchen.
Myth 5
As the saying goes, "practice three nines in winter, practice three dogs in summer" - let's play games with the sunshine!
The truth:
Rash activity in a high temperature environment often leads to chest tightness and shortness of breath, rapid heartbeat and even fainting, during outdoor activities in summer, once there is discomfort, you should immediately stop all activities and go to a cool and ventilated place to rest.
Correct Approach:
It is best to avoid going out in hot weather, and if you want to go out, it is best to choose a relatively cool time in the morning and evening, and move more in the shade to avoid direct sunlight. If you need to move in high temperature conditions, you should gradually increase the intensity and gradually adapt to the environment.
If you want to exercise a better tolerance for high temperatures, you should turn off the air conditioner for a period of time, or go outdoors in the early morning or evening. If you need to work in hot areas in the future, there should be a process of adapting to the climate, and then you should carry out intensive work.
