people prone to heatstroke:
infants: infants have imperfect systemic development, poor thermoregulation function and more subcutaneous fat, which is unfavorable to heat dissipation.
pregnant women: because of heavy physical exertion and weakness during pregnancy or postpartum, if you stay indoors with poor ventilation and high temperature for a long time, you are prone to heatstroke.
elderly: due to the atrophy of skin sweat glands and the decline of circulatory system function, the heat dissipation function of the elderly with weak physique is reduced and they are prone to heatstroke.
patients with cardiovascular disease: hot weather will excite the sympathetic nerve of patients with cardiovascular disease and increase the load of cardiovascular disease. Especially those with cardiac insufficiency, their body heat can not be dissipated and stored in time, so they are prone to heatstroke.
diabetic patients: the body of diabetics is slow to respond to the temperature changes inside and outside the body. Although the heat has been stored in the body, the patient’s self-conscious symptoms appear later and are easily heatstroke.
patients with infectious diseases: bacterial or viral infection can make the body produce endogenous pyrogen and act on the hypothalamic heat producing center, so as to enhance the heat production of the body. It can also make the body release a large number of catecholamines into the blood, cause vasospasm and contraction, affect heat dissipation and cause heatstroke.
malnourished: malnourished people have decreased blood pressure due to lack of nutrients, which reflexively causes vasoconstriction. They are also prone to recurrent diarrhea, leading to dehydration and electrolyte disorders, leading to heatstroke.
some drug users: people taking antihistamines, anticholinergics, sleeping pills, etc. will also have vasoconstriction, which will hinder the thermoregulation center and be prone to heatstroke.
people who work outdoors in the scorching sun or in a muggy and high-temperature environment: mainly include bus drivers, traffic police, construction workers, farmers, field explorers, students taking physical education classes in the open air, or workers in front of the furnace of the steel mill, operators of the hot-rolled steel mill, spinning workers and boiler workers of the textile mill.
heatstroke symptoms: chest tightness, palpitation, limb weakness
the degree of heatstroke can be divided into three levels: first, premonitory heatstroke, there will be a lot of sweating, thirst, dizziness, tinnitus, chest tightness, palpitation, limb weakness, inattention, and the body temperature does not exceed 37.5 ℃; Second, mild heatstroke. It has the symptoms of threatened heatstroke, and the body temperature is above 38.5 ℃, accompanied by flushing, chest tightness, skin burning and other phenomena; Or the skin is wet and cold, vomiting, blood pressure drops, and the pulse is thin and fast; Third, severe heatstroke. In addition to the above symptoms, syncope or spasm occurs; Or not sweating, and the body temperature is above 40 ℃.
heatstroke prevention: the colder you eat, the more likely you are to heatstroke
in terms of diet, you should first pay attention to supplementing water. In summer, the body’s water volatilizes more, so you can’t drink water when you are thirsty. At that time, the body is in a state of water shortage. In addition, you should drink some salt water appropriately to supplement the trace elements taken away with the evaporation of water in the body. In terms of food, we should supplement enough protein, such as fish, eggs, milk and beans; Eat more fresh fruits and vegetables that can prevent heatstroke, such as tomatoes, watermelon, balsam pear, cucumber, etc. As for cold drinks, the colder you eat, the more likely you are to suffer from heatstroke. Because the short-term decrease of local temperature of human body will affect the human digestive system, and then affect the normal operation of various system functions.
when going out, do a good job in sunscreen. It’s best to wear long sleeved shirts, shawls and sunshades when cycling for a long time in the scorching sun. For long-term outdoor sports, prepare heatstroke prevention drugs, such as shidishui, Rendan, etc. Do not turn the air conditioning temperature too low. Too large indoor and outdoor temperature difference will also lead to heatstroke.
heatstroke first aid: replenish water and ventilate around
. In case of heatstroke symptoms, stop what you are doing immediately and sit down in a cool place; At the same time, replenish water and drink slowly to prevent aggravating the burden on the heart. Untie the collar button, tie, belt, etc., maintain ventilation around the body, and apply or take antipyretic drugs; After a period of rest, if the symptoms do not decrease but increase, seek medical treatment in time. Once heatstroke occurs around, the patient shall be moved to a cool place immediately and the surrounding ventilation shall be maintained; Unbutton the clothes to help the body dissipate heat; Help take heatstroke relieving drugs, and press acupoints such as human middle and tiger mouth to help restore consciousness. If the symptoms do not alleviate, call the rescue phone immediately.
tips for dealing with summer heat
1. Drink water: drink slowly and don’t drink hard when you are thirsty; Drink warm water, not ice water; Drink water regularly, not when you are thirsty; Drink boiled water, not raw water; Drink fresh warm water instead of & ldquo; Chen & rdquo; Water; You can also drink more warm water with light salt.
2. Drink some diluted electrolyte drinks: stay away from alcohol, caffeine and cigarettes.
3. Slowly adapt to the change of temperature: when engaging in outdoor activities, slow down and don’t show off.
4. Timely heat dissipation: when it is too hot, wash the head and neck with cold water to let the water evaporate to help heat dissipation.
5. Pay attention to weight changes: heatstroke may cause the body to collapse gradually in consecutive days, so pay attention if the weight drops sharply in a few days.
6. Wear a hat when going out: wear a hat when going out in summer to slow down the heat absorption of the head and neck, especially those who are bald or have little hair.
7. Don’t go out shirtless: to avoid absorbing more radiant heat. Ventilated cotton shirts have a more sunstroke relieving effect than shirtless.
8. Wear light colored clothes: cotton and polyester synthetic clothes are the most breathable.
9. Eat more melons: white gourd diuresis, anti-inflammatory, heat clearing and detoxification; Towel gourd can relieve heat and expel wind, dissipate phlegm and cool blood; Balsam pear dispels heat and clears the heart; The cellulose in cucumber can excrete the rotten food in the intestine and reduce cholesterol; Pumpkin can replenish qi, diminish inflammation and relieve pain.
10. Eat more cold vegetables: , such as tomatoes, eggplants, lettuce, asparagus, etc.
11. Eat more bitter vegetables. is conducive to relieving summer heat, dryness and dampness. Balsam pear, bitter vegetables, Kuding tea and bitter bamboo shoots are all excellent food for summer heatstroke prevention.
12. Take more baths: help sweat leave the human body.
