Proposal to require Lanzhou University to stop running sports
It is winter, and the temperature has dropped to the coldest time of the year. The ice on the roads has not melted for a long time, the snow on some fields and grasslands has not diminished for a long time, and Cuiying Mountain is still white. The intensity of solar radiation is decreasing day by day, and the minimum temperature is decreasing day by day. Lanzhou just received the biggest snowfall in December in the 21st century not long ago. After the snow, the temperature plummeted, and Yuzhong even exceeded -16.0℃, breaking the lowest temperature since January 9, 2014. Official data from the Central Meteorological Observatory showed that the running temperature reached -21.4°C, and the comfort level was extremely cold and extremely uncomfortable. And we predict that on Thursday morning, the temperature will continue to decline and may exceed -17°C, reaching the lowest value since December 31, 2012.
It’s freezing cold, but the school is still organizing running exercises. According to analysis by Qingyulan University combined with authoritative data from the Central Meteorological Observatory, among big cities, only Harbin had a lower minimum temperature than Yuzhong on Wednesday, but its snow cover was 14cm; only Urumqi had a lower minimum temperature than Yuzhong on Tuesday, but its snow cover was 35cm; in other cities, only Urumqi had a lower minimum temperature than Yuzhong, but its snow cover was 14cm. Small areas that are colder than Yuzhong are sparsely populated and are either located in Inner Mongolia or on the Qinghai-Tibet Plateau or the Tianshan Mountains. These places are covered with snow all year round, which indirectly proves that Lanzhou University is still the coldest among the well-known institutions of higher learning. .
Landa attracts people from all over the world to study. In the first winter after entering Lanzhou, you will experience an extreme minimum temperature that is about 30°C lower than that of their cities. Not to mention that morning exercise in the severe cold not only means shortening the rest time, not only means sacrificing comfort and a good life experience, but also means potential risks to health, which obviously violates the original intention of morning exercise. For southerners who have no experience in keeping warm, minus 10 degrees Celsius can already cause health problems. Because the ability of the respiratory tract to eliminate bacteria is significantly weakened, the risk of bacterial invasion is significantly increased, causing winter colds, which obviously affects the study of professional courses and preparation for the final exam; after being exposed outdoors for about 40 minutes, the temperature difference is close to 40°C indoors. It is more likely to cause body function disorders and more likely to cause colds. On the other hand, due to the influence of cold and high pressure, the amount of heating increases and the weather stability improves, which also leads to an increase in pollution emissions and a reduction in air pollution diffusion conditions. We predict that starting from the night of Wednesday the 16th (Wednesday), Yuzhong campus will be affected by a wave of PM2.5 air pollution. Due to the influence of weak cold air on the 21st, the concentration dropped temporarily, but it is expected that calm weather will develop again from the night of the 23rd, and there will be another wave of air pollution. In severe cold conditions, the respiratory tract inhales a large amount of cold air, which reduces the ability to resist pollutants. Coupled with the inhalation of pollutants, the risk of respiratory diseases significantly increases.
Since morning exercise requires long-term exposure to the outdoors, and the relative movement with the air during running increases heat transfer, it may also cause the risk of frostbite or even frostbite on exposed parts of the body such as hands, nose, ears, and cheeks. . Many students are already complaining that after morning exercises, their faces and ears almost lose feeling, and are stiff and painful when touched. This is a significantly bad sign to the body. In addition, for people with heart disease, exposure to air below -15°C means the narrowing of blood vessels. This, combined with the amount of exercise itself, significantly increases the risk of heart attack. According to the climate forecast, due to the influence of the stable Central Asian trough, the cold air continues to replenish our school. The temperature will be low for a period of time, and the low temperature of -18~-12℃ will remain for a period of time. Continuing to run and exercise under such circumstances will undoubtedly do far more harm than good to the human body, especially for people who have no experience in keeping warm in cold weather. We are not against aerobics, we are only opposed to aerobics in cold weather. We predict that we may experience a wave of warming in early January, when the weather may be suitable for running exercises. Therefore, we initiated a proposal to suspend running exercises immediately. If you respond to this proposal, what you can do is forward this proposal to the students you care about and know, let them understand the dangers of running in cold weather, and provide feedback to relevant departments in the way you know.
