In summer, what good heatstroke prevention and cooling methods are there?

Tips for heatstroke prevention and cooling in summer The following are some tips for your reference, reminding residents to take heatstroke prevention and cooling measures and pay attention to their health.

First, replenish water in time but drink less drinks. Juice, cola, sprite, soda and other drinks contain more saccharin and electrolyte. Drinking too much will cause bad stimulation to the gastrointestinal tract and affect digestion and appetite. So drink more boiled water or light salt (sugar) boiled water in summer. Second, it is not advisable to binge drink after being thirsty. After sweating a lot in labor and sports, it is not advisable to drink a lot of white water, and some light salt (sugar) water should be supplemented appropriately, because after sweating a lot, too much salt is lost in the human body, accounting for about 0.5% of sweat. If salt is not supplemented in time, the ratio of water to salt in the body will be seriously unbalanced, leading to metabolic disorder. 3. The strongest time of solar short-wave radiation is around 10-15. Try to avoid going out during this time, and apply some sunscreen skin care products to your skin. It is best to wear light clothes in summer. Fourth, it is not advisable to drink too much. In summer, human body is easily affected by temperature, and excessive damp heat is the cause of skin sores, carbuncle and toxic swelling. If you drink a lot of white wine, it will contribute to dryness and dampness, which is tantamount to adding fuel to the fire. Fifth, the diet should not be too light. In summer, people have long activities, sweat a lot and consume a lot. They should eat more nutritious foods such as chicken, duck, lean meat and fish eggs to meet the metabolic needs of the human body. Sixth, the nap time should not be too long. If the nap time is too long, the central nervous system will deepen the inhibition, the cerebral blood flow will be relatively reduced, and the metabolic process will slow down, leading to discomfort after waking up and more sleepiness. 7. Avoid "rapid cooling" after heating. In hot summer, when people go out or come back from work, they like to either turn on the electric fan or take a cold bath immediately, which will make the pores of the whole body close quickly, but the heat in the body is difficult to dissipate, and it will also cause insufficient blood supply to the brain due to the rapid contraction of blood vessels in the brain, which makes people dizzy. Eight, air conditioning indoor and outdoor temperature difference should not be too big. The temperature difference between indoor and outdoor air conditioners should not exceed 5 degrees. Even if the weather is hot again, the indoor temperature of the air conditioner should not be lower than 24 degrees. Nine, it is not appropriate to wear metal jewelry. Some metals in metal ornaments will be stained with sweat, and the skin that comes into contact with them will appear reddish or itchy when wearing, which may easily lead to contact dermatitis. Ten kinds of people are prone to heatstroke: 1. Compared with ordinary people, some people with poor health or other diseases are more prone to heatstroke, so in hot weather, they and their families should pay more attention. 2, the elderly due to skin sweat gland atrophy and circulatory system function decline, the body heat dissipation is not smooth. 3. Pregnant women are weak because of their great physical exertion during pregnancy or postpartum. If they stay indoors with poor ventilation and high temperature, they are prone to heatstroke. 4. Infants and young children's systems are underdeveloped, with poor thermoregulation function and more subcutaneous fat, which is not conducive to heat dissipation. 5. Hot weather will excite the sympathetic nerves of patients with cardiovascular diseases and increase the cardiovascular load. Especially for people with heart failure, the heat in the body can not be distributed and accumulated in time, which is easy to suffer from heatstroke. The body of diabetic patients is slow to respond to the temperature changes in the internal and external environment. Although heat has accumulated in the body, the patient's conscious symptoms appear late, which is easy to cause heatstroke. 6, some patients with infectious diseases, due to bacterial or viral infection can make the human body produce endogenous pyrogen, so that the body's heat production is accelerated. Inflammation can also cause the body to release some substances, causing vasospasm and contraction, which is not conducive to heat dissipation and is prone to heatstroke. 7. Malnourished people will lower their blood pressure due to lack of nutrition, which will lead to reflex vasoconstriction. They are also prone to recurrent diarrhea, leading to dehydration and electrolyte disorders and heatstroke. 8. People who take antihistamines, anticholinergic drugs, sleeping pills, etc. There will also be vasoconstriction, which will lead to disorder of thermoregulation center and easy heatstroke. Eleven, drink more light salt water, go out less in the afternoon: In addition, the elderly, the weak, pregnant women, obesity, hyperthyroidism, diabetes, cardiovascular disease patients are also prone to heatstroke. Therefore, once dizziness, fatigue, dry mouth, nausea and vomiting, fever, convulsions, convulsions, anhidrosis, dyspnea and other symptoms appear. When it happens, you should immediately rest in a cool and ventilated place or wet compress with cold water and ice water, and then go to the hospital immediately. If the treatment is not timely, it will easily lead to complications and even death. In order to prevent the occurrence of heatstroke, in addition to avoiding going out from the morning to 2 pm in the strongest sunshine 10, necessary protective measures should be taken: ① keep indoor ventilation and lower the room temperature, at least with electric fans; ② Working hours at high temperature should not be too long, and should not exceed 8 hours every day; (3) Reduce labor intensity, prepare heatstroke prevention and cooling drinks, and supplement brackish boiled water or salty drinks as much as possible; Ensure adequate sleep and eat more nutritious fruits and vegetables. ⑤ Try to penetrate the air-cooled cotton-padded jacket.
