A proposal to request the closure of Lanzhou University.

It was winter, and the temperature dropped to the coldest time of the year. Road ice has not been changed for a long time, and the snow in some stations and grasslands has not been reduced for a long time. Cuiying Mountain is still white. The intensity of solar radiation is decreasing, and the minimum temperature is decreasing. Not long ago, Lanzhou just had the biggest snowfall in 65438+February since the 20th century. After the snowfall, the temperature plummeted, and Yuzhong broke through-16.0℃, breaking the lowest temperature since 20 14 and 19. According to the official data of the Central Meteorological Observatory, the somatosensory temperature of running exercise reaches -2 1.4℃, and the comfort is extremely cold and extremely unsuitable. And we predict that the temperature will continue to drop on Thursday morning, possibly exceeding-17℃, reaching the lowest value since 2012/February 3 1.

It's freezing, but the school is still organizing running exercises. According to the authoritative data analysis of Qingyu Lanzhou University and the Central Meteorological Observatory, the lowest temperature in Harbin on Wednesday was lower than that in Yuzhong, but the snow was14 cm. ; On Tuesday, the lowest temperature in Urumqi was lower than that in Yuzhong, but the snow was 35cm. Other small cold areas in the middle of the desert are sparsely populated, either in Inner Mongolia, the Qinghai-Tibet Plateau or the Tianshan Mountains. The perennial snow in these places indirectly proves that Lanzhou University is still the coldest running exercise in famous universities.

Lanzhou University attracts people from all corners of the country to study. During their first winter in Lanzhou University, they will experience an extreme minimum temperature about 30℃ lower than that in their city. Not to mention that morning exercise in cold weather not only means shortening the rest time, but also means sacrificing comfort and good life experience. It only means the potential risk to health, which obviously goes against the original intention of morning exercise. For southerners who have no experience in keeping warm, minus 10℃ has caused health problems. Because the ability of respiratory tract to eliminate bacteria is obviously weakened, the risk of bacterial invasion is obviously increased, which leads to a cold in winter and obviously affects the study of professional courses and the preparation for the final exam. Exposed to the outside for about 40 minutes, the temperature difference close to 40℃ indoors is more likely to cause the disorder of body function and more likely to cause a cold. On the other hand, due to the influence of cold and high pressure, the heating capacity is increased and the weather stability is improved. At the same time, the pollution emission is increased and the diffusion conditions of air pollution are reduced. We predict that Yuzhong campus will be affected by a wave of PM2.5 air pollution from Wednesday night of 16. 2 1 day, affected by weak cold air, the concentration decreased briefly, but it is expected that the quiet weather will develop again at night on the 23rd and will encounter another wave of air pollution. When it is cold, the respiratory tract inhales a lot of cold, and the resistance to pollutants decreases. Coupled with the inhalation of pollutants, the risk of respiratory diseases has increased significantly.

Because morning exercises need to be exposed to the outside for a long time, the relative movement with the air increases the heat transfer during running, and may also cause the risk of frostbite or even frostbite in exposed parts of the body such as hands, nose, ears and cheeks. Now many students are complaining that after morning exercises, their faces and ears are almost unconscious and feel stiff and painful. This is an obvious bad signal to the body. In addition, for people with heart disease, exposure to air below-15℃ means narrowing of blood vessels, and the amount of running exercise itself obviously increases the risk of heart attack. According to the climate forecast, the temperature will be low for some time due to the influence of the stable central Asian trough and the continuous supplement of cold air, and the low temperature will be maintained at-18~- 12℃ for some time. In this case, continuous running exercise will undoubtedly do more harm than good to people, especially those who have no warm-keeping experience in cold weather. We don't object to running, we only object to running in cold weather. We expect that/kloc-0 may experience a wave of warming at the beginning of the month, and from the weather, it may be suitable for running. Therefore, we put forward the suggestion of stopping running exercise immediately. If you respond to this suggestion, what you can do is to forward this suggestion to the students you care about and know, let them know the harm of running exercise in cold weather, and give feedback to the relevant departments in a way you know.
