The roof of a cultural relic memorial hall in Chongqing collapsed by the sun! How fierce is the hot weather?

Chongqing has always been famous for its stoves. This time, the roof of Chongqing Cultural Relics Memorial Hall collapsed on a hot day, which is also outrageous. So what harm does hot weather do to our life?

Different temperatures affect people's physiological activities, and high temperature is unfavorable to the intermediary of body temperature. Under normal circumstances, the human body regulates body temperature through conduction, convection, radiation and evaporation, which is suitable for both internal and external use. When the weather is hot, it is difficult for the human body to dissipate heat, and the body temperature regulation function is limited, which is easy to cause heat accumulation in the body and cause heatstroke. Therefore, high temperature is a disastrous weather, especially continuous high temperature, which is extremely harmful to human body.

High temperature weather will obviously reduce soil moisture and make agricultural soil moisture worse. The soil is easy to dry and crack, which will definitely affect the growth of agriculture. The severe drought in southwest China last winter and this spring obviously affected many crops. It will also affect the water supply of Shijiazhuang, Taiyuan, Datong, Inner Mongolia and many other northern cities, and the water supply in these cities is already very tight. If high temperature and heat waves persist, the contradiction between supply and demand will intensify, and strict water-saving measures will be taken when necessary. In the northeast of China and other forest areas, there will be more forest fires. In the case of high temperature, if lightning strikes again, the trees will be dry and the air humidity will be low, which will easily lead to forest fires.

High temperature will affect the power supply. Now the electricity consumption has reached a peak that has not been seen for many years. Fortunately, the power sector is ready, but if there is a long-term high temperature heat wave, the power load will be very heavy. It may even cause pollution problems. In the long-term high temperature heat wave, many inland lakes will produce more and more eutrophication and cyanobacteria, and the water pollution will be intensified. In the past few years, the cyanobacteria in Taihu Lake and Chaohu Lake all occurred in the early stage under the condition of high temperature and heat wave, so high temperature will induce water pollution. Harming human health is a very important problem. Now the indoor temperature difference is very obvious. If you suddenly run from an air-conditioned place to a very hot place, people will not adapt, which will cause colds and so on. The most vulnerable groups are the elderly and children, because their resistance is weak, mainly respiratory and cardiovascular diseases, and their heart rate and breathing will be accelerated. These problems are caused by respiratory and cardiovascular diseases.
