The national hot cry warning map was released. Where did this wave of high temperature spread?

With the attack of high temperature, many high-temperature heat waves raged in northern China, and this high temperature has the characteristics of long duration and high intensity. The Central Meteorological Observatory has issued a high temperature warning for 10 days. With the appearance of high temperature warning map, many places have fallen into high temperature area. Among them, most of Henan, southern Hebei, northern Jiangsu and Anhui, northern Hubei, southeastern Shaanxi, eastern Xinjiang and western Inner Mongolia have become the core areas of this round of high temperature. The local temperature is over 37 degrees, even over 40 degrees, and the temperature is relatively hot. The temperature in these affected places is also very high at night. The scorching sun in the north and the steaming heat in the south will give us a feeling of melting.

With the continuation of the heat wave, the pattern of steaming in the south and roasting in the north will continue, and then the heat wave will travel along the longitude and latitude lines to Henan, Shandong, Hebei, south-central South China, Beijing, Southeast China and Tianjin. It can be seen that the sweltering heat in the south is increasing, and then the northwest will not be affected by the high temperature, which means that the northwest will take the lead in withdrawing from the high temperature warning map.

So how can we scientifically prevent heatstroke and cool down the high temperature? Generally speaking, the temperature is 32 degrees and the humidity is below 60%, which is the adaptation stage of human body to higher temperature. But once the temperature reaches 35 degrees and the humidity exceeds 60%, it is the critical point of heatstroke. When the temperature exceeds 37 degrees and the humidity exceeds 80%, it is easy to get heatstroke. Then, when the temperature reaches 37 degrees, many organs in the human body will participate in cooling activities, such as sweating through sweat glands, expanding skin blood vessels and increasing blood flow. Although your body is trying to cool you down, due to the high surface temperature, your body will be dizzy and unstable after a period of overload operation, so at this time, you should go to a cool place or take better cooling measures to cool down.

Precautions for heatstroke prevention and cooling: the air conditioning temperature should not be lower than 26 degrees. Open the window regularly for ventilation. When you enter the air-conditioned room from the hot outdoor, you must dry your sweat in advance to prevent you from getting sick. Change clothes in time when sweating, avoid taking a bath immediately after sweating, and don't take a bath with cold water, because taking a bath with cold water is a kind of body circulation, which is easy to induce cardiovascular and brain diseases. Secondly, it is necessary to appropriately increase the lunch break to ensure sleep time and avoid being in the process of work when the temperature is extremely high. Finally, during the trip, we should pay attention to avoiding noon time, replenish water in time, and always keep summer medicine such as Huoxiang Zhengqi Water and Fengyoujing.

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