This summer is really too hot. How hot is it? You can tell how powerful it is from the number of hotly searched news items today because of the hot weather.
Why is it so hot this summer?
Reason 1: Atmospheric circulation Periodic fluctuations
Recently, Eurasia mid-high latitudes westerly belt circulation has relatively large periodic fluctuations, making cold air activities more frequent, among which the Ural Mountains blocking high pressure and the East Asian trough have strengthened in stages. , which has triggered three cold wave weather processes since late April.
Reason 2: Impact of La Niña event
Affected by the La Niña event, the meridional direction of the Eurasian mid-high latitude circulation is large and its periodic fluctuations are obvious. The frequent activity of cold air affects my country's climate background conditions.
Reason three: It is the time of late spring and early summer.
Every time in late spring and early summer, the precipitation in the central and eastern regions of my country gradually decreases, which causes the cold air to warm up quickly during the intermittent period.
How long will it continue to be so hot? When will it end?

According to the 36th Climate Prediction Bulletin for 2022 released by the National Climate Center on July 4, it is expected that in the next 15-30 days (July 18 to August 2, 2022), Beijing, Tianjin, Hebei, Shanxi, and Inner Mongolia Most of the regions, Liaoning, Jilin, Heilongjiang, Guangdong, eastern Guangxi, Hainan, northern Shaanxi, northeastern Gansu, Ningxia and other places have more precipitation than the same period in normal years; my country will have two obvious high-temperature weather processes: July 18-21. Central East China, central China, the eastern part of Southwest China, and northern Xinjiang; July 24-28, most of East China, most of Central China, and the eastern part of Southwest China.
In addition, in the latest 2022 No. 37 Forecast Announcement, it is expected that from July 25 to August 9, precipitation in Northeast China, eastern Inner Mongolia, southeast China, most of South China, and eastern Northwest China will be higher than normal for the same period in the past year.

Judging from the Meteorological Bureau forecast results, this summer has just begun, and the high temperature will continue for a long time!
What impact does high temperature weather have on us?
High temperature weather has a very obvious impact on the emotional regulation center of the human body's hypothalamus. Coupled with excessive sweating and electrolyte metabolism disorders in the human body, it seriously affects brain nerve activity. In addition to making people feel uncomfortable and reducing work efficiency, it can also cause many Various diseases related to high temperature, such as heatstroke, heat stroke, heat cramps, heat exhaustion, cardiovascular and cerebrovascular diseases, depression, anxiety disorders, irritability, schizophrenia and other serious mental illnesses. At the same time, it may also cause high-temperature emotional disorders such as insomnia, irritability, irritability, and restlessness.
When the human body is in a high-temperature and high-humidity environment, cognitive abilities will be significantly interfered with and damaged, resulting in reduced short-term memory capacity, scattered attention and poor stability, difficulty in thinking and imagination, and reduced alertness. When the ambient temperature exceeds 32°C, average performance and test scores will be reduced or attenuated by 15%. In particular, complex cognitive abilities such as working memory (spatial span test, pattern recognition) are significantly damaged in high temperature environments.
Therefore, we are more irritable, impulsive, and prone to losing our temper in summer. Everyone should know that this is because of the hot weather. At this time, only air conditioning and cold drinks can help us.
What is heat stroke?
Heat stroke (heat stroke) refers to the disorder of human body temperature regulation caused by high temperature, excessive accumulation of heat in the body, resulting in damage to nerve organs. Heat stroke is severe heat stroke in the classification of heat stroke. It is a fatal disease with a high mortality rate. The disease usually occurs in summer when high temperatures are accompanied by high humidity.
In layman’s terms, heat stroke is the most dangerous and serious form of heatstroke, with a high mortality rate.In the past, we often said "it's so hot", which was just an exaggeration. But this year, due to the hot weather, many people across the country were sent to the hospital for treatment due to heat stroke. For example, yesterday there was a 32-year-old courier A member of the staff was admitted to the ICU with heat stroke. Many of our compatriots even died before because the rescue was not timely.
Heat stroke is a severe form of heat stroke, and if treatment is not received promptly, the mortality rate can be as high as 60%. Heat stroke is more likely to occur in an environment with high temperature, high humidity, and no ventilation. During the high temperature season every year, workers working outdoors and those doing physical training outdoors are all at high risk of heat stroke. If our family members are engaged in these jobs and they don’t understand this, we need to remind them to pay attention to protection.
How to prevent heat stroke?
Outdoor workers should take appropriate rest when working under high temperatures, and the intensity of labor should be gradual. After sweating a lot, the lost water and salt must be replenished in a timely and effective manner. Try to avoid staying outdoors for long periods of time in the scorching sun. If you feel unwell, you should move to a cool place, lower your body temperature, and be sent to the hospital as soon as possible.
In addition, the elderly and children who stay at home, as well as some groups with underlying diseases, are also high-risk groups for heat stroke, so they should pay more attention to preventing heatstroke. If conditions permit, you can turn on the air conditioner at home to enjoy the cool air, or open windows for ventilation. Pay special attention to the elderly who live alone. The elderly do not like to turn on the air conditioner. The ambient temperature and humidity are high and they are prone to heatstroke. As children, we should try our best to help the elderly with various heatstroke prevention and cooling tasks in advance, prepare enough refreshing drinks and heatstroke prevention and cooling medicines at home, persuade them to reduce outdoor activities, and send the elderly to the doctor as soon as possible if they feel unwell.
Life is hard and tiring. Friends, we need to remember that we are the backbone of the family, and the family needs to be supported by us. We take good care of ourselves, which is the greatest responsibility for ourselves and the family. Only then can our family be happy and happy.
