From the high temperature this summer, it can be seen that climate warming has reached a very high level, but I never expected that even the Arctic, which everyone knows as an "extremely cold place", has become a zone where you can wear short sleeves, and climate warming is terrifying.

What are the effects of high temperature weather on human health?

Temperatures were high in most parts of the country in July this year. High temperature weather will make the human body feel uncomfortable, work efficiency will be reduced, the incidence of heat stroke, intestinal diseases and cardiovascular and cerebrovascular diseases will increase, and it is easy to affect the normal production and work order.

Medical studies have shown that ambient temperature is closely related to the physiological activity of the human body. The most comfortable ambient temperature of the human body is between 20-28 ° C, the most ideal temperature is 15-20 ° C, in this environment people have strong memory and high work efficiency; When the temperature is 4-10 °C, the incidence is higher, and when it is below 4 °C, it is easy to develop chilblains and the incidence is higher. When the ambient temperature is higher than 28°C, people will feel uncomfortable. No matter how high the temperature is, it is easy to cause irritability, heat stroke, and mental disorders. At 30°C, the sweat glands of the body will all be put into work; Temperatures above 34°C, accompanied by frequent heat wave shocks, can also cause a series of diseases, especially heart, cerebrovascular and respiratory diseases, the incidence of diseases increases, and the mortality rate increases significantly. High temperatures above 37 ° C have a certain damage to the protein of the human body. If the human body temperature reaches above 40°C, the center of life will be directly threatened.

This is because the human body is through the central nervous system of the brain to direct normal activities, the heat generated in the body and the heat emitted are basically equal, the body temperature is generally maintained between 36.5-37 ° C, the heat dissipation of the human body, in addition to breathing, urine and urine, mainly through the skin layer to dissipate heat. Due to the appearance of hot weather, the heat balance of the human body is disrupted and heat stroke and other diseases occur. Therefore, meteorologically, the maximum temperature of the day is greater than or equal to 35 °C as high temperature weather.

In hot days, many people have had such questions, why is it that it is so hot that it is only a pinch of cumin away from the barbecue, but the live temperature released by the meteorological department is not very high? The human body's perception of temperature is also affected by a variety of factors other than the temperature itself, such as humidity, wind speed, solar radiation, clothing and even mood, for example, when the temperature is 35.6 °C, if the relative humidity is 45%, the human body will feel the high temperature of 40 °C; If the relative humidity reaches 65%, the perceived temperature will be close to 50°C. Continuous high temperature weather will make the human body feel uncomfortable, for the elderly with cardiovascular disease can not be ignored, once relaxed vigilance is very easy to occur heart failure, and heart failure is the end stage of various heart diseases, known as the stumbling block of life, seriously endangering life and health.
