The national heat cry warning map has been released. Where has this wave of high temperature affected?

With the onset of high temperatures, high temperature heat waves are raging in many places in northern my country, and this high temperature is characterized by long duration and strong intensity. The Central Meteorological Observatory has issued high temperature warnings for 10 consecutive days. With the emergence of high temperature warning maps, many places have fallen into high temperature areas. Among them, most of Henan, southern Hebei, northern Jiangsu and Anhui, northern Hubei, southeastern Shaanxi, eastern Xinjiang, and parts of western Inner Mongolia have become the core areas of this round of high temperatures. The local temperature exceeds 37 degrees and even exceeds 40 degrees. The temperature is relatively hot, and in these affected places, the night temperature also remains high. The scorching sun in the north and the steaming heat in the south will give us a melting feeling.

As the heat wave continues, the pattern of steaming in the south and roasting in the north will continue, and then the heat wave will move along the longitude and latitude lines in Henan, Shandong, Hebei, central and southern China, Beijing, southeastern China, Tianjin and other places , it can be seen that the sultry heat in the south continues unabated, and then the northwest region will not be affected by the high temperature. The northwest region will be the first to exit the high temperature warning map, which also means that the northwest region can be relaxed.

So how can we scientifically prevent heatstroke and cool down the heat? Generally speaking, when the temperature is 32 degrees and the humidity is below 60%, it is the human body's adaptation stage to higher temperatures. But once the temperature reaches 35 degrees and the humidity exceeds 60%, it is a critical point for heat stroke. When the temperature exceeds 37°C and the humidity exceeds 80 % are prone to heatstroke. When the temperature reaches 37°C, multiple organs in the human body will participate in cooling activities. For example, the human body perspires through sweat glands, skin blood vessels expand, and blood flow increases. Although your body is trying its best to cool you down, due to the high body surface temperature, your body will become dizzy and unstable after a period of overloaded operation. At this time, you need to turn Go to a cool place or use better cooling measures to cool down.

Precautions for heatstroke prevention and cooling. The air-conditioning temperature should not be lower than 26 degrees. Open windows regularly for ventilation. When entering an air-conditioned room from hot outdoors, be sure to wipe off the sweat in advance to prevent illness. Change clothes in time when you sweat. Do not take a shower immediately after sweating, and do not take a shower with cold water, because taking a cold water shower is a cycle of the body and can easily induce cardiovascular, heart and brain diseases. Secondly, we should increase the lunch break appropriately and ensure the sleep time, so as to avoid working when the temperature is extremely high. Finally, when traveling, be careful to avoid the noon period, replenish water in time, and always have Huoxiang Zhengqi water, Fengyoujing and other summer-relieving medicines with you.

Finally, I hope everyone can scientifically prevent heatstroke and cool down to cope with the hot summer.
