How to prevent heat radiation disease in high temperature weather

Since entering the dog days, many provinces and cities have suffered from "heat radiation disease" due to the high temperature The hot weather will continue to rage How to prevent heat radiation disease has become a concern of many people Heat radiation disease belongs to severe heatstroke, with a mortality rate of up to 50% Generally speaking, people who stay in high temperature or high humidity environment for a long time tend to have trouble in thermoregulation Once the heat is difficult to escape from the body, people will have limb spasm, blood pressure drop, nausea and vomiting and other heatstroke symptoms The death rate of heat radiation disease is as high as 50% Because patients are prone to multiple organ failure (central nervous system dysfunction, renal failure, liver failure, circulatory failure, respiratory failure, disseminated intravascular coagulation, etc.) If four or more organs of the human body have dysfunction, the mortality rate is close to 100% The heat radiation disease is mainly caused by the high temperature environment, and it is easy to cause the heat radiation disease when exposed to the high temperature environment for a long time For example, a young man we visited some time ago, who spent 5-6 hours in the high temperature, suddenly fell to the ground, convulsed, delirious and so on Although there is no life danger after rescue, it is still under observation in the hospital However, it should be noted that the temperature is not very high, but high humidity can also cause heatstroke The temperature may only be 32 ℃, but the humidity is very high, for example, the humidity reaches 70% or even more than 80%, which may also cause heatstroke Because the human body mainly heats up through perspiration, the excessive humidity of the external environment will affect the human body's perspiration, which is easy to cause heatstroke Not only in summer, but also in winter, when the sun is soft and the wind is biting In winter, many people like to steam sauna, but we must do what we can Don't stay in the sauna room for a long time In case of dizziness and nausea, leave the sauna room immediately to prevent heatstroke If the temperature difference is more than 5 ℃, how can people avoid the heat radiation disease when they go out from the air-conditioned room? First of all, try to reduce the stay time outside in high temperature weather If you need to go out in special circumstances, you must also go in the shade Second, pay attention to ventilation and cooling at home and office If the windows of the air conditioning room are closed tightly, the ventilation condition is poor, and there are many people in the room, heatstroke may also occur Pay attention to proper ventilation At the same time, the indoor temperature should not be too low The indoor temperature is low, the indoor and outdoor temperature difference is big, the human's heat resistance will reduce If the temperature difference is more than 5 ℃, people are more likely to get heatstroke when they go out of the air conditioning room It is generally believed that it is appropriate to set the air conditioner at 26-28 ℃ Third, drink more water and add salt properly Drinking water should be "measured in", according to their own sweat to decide how much water to add Generally speaking, it's better to drink 1.5 to 2 liters of water every day in summer It is better to replenish water in small amount and many times Under the high temperature environment, it's better to drink water once every half an hour, 200 to 300 ml at a time, not cow At the same time, drinking water does not forget to add salt People sweat to dissipate heat, and sweat will take away a lot of salt from the body Add half a spoonful of salt to a litre of water to replenish the salt lost in the body With the improvement of people's awareness of prevention, the number of patients with heat radiation disease is relatively small this year, but we should not take it lightly These two months are the high incidence season of heat radiation disease, especially for the elderly, children, pregnant women, the vulnerable and special occupations that need outdoor work It is recommended to avoid going out between 10 a.m and 2 p.m if you feel signs of heatstroke, you should immediately transfer to a cool and ventilated place to rest, and pay attention to replenishing water.
