Berlin, Germany suffered from cold weather. What adverse effects will this weather have?

Low temperature, rain, snow and freezing weather are obviously harmful to human health and will lead to decreased immunity. In addition to common diseases such as colds, respiratory diseases, cardiovascular and cerebrovascular diseases, falls, fractures and frostbite. If this phenomenon lasts for a long time, it may also induce psychological diseases such as depression, helplessness and psychological imbalance, as well as corneal damage caused by reflected light from ice and snow, causing tears, tingling and photophobia. Low-temperature snowfall refers to the precipitation composed of a large number of white opaque ice crystals (snow crystals) and their polymers (snow blocks). During the falling process of snow crystals, under the comprehensive influence of meteorological factors such as temperature and humidity, water vapor supersaturation, physical collision and adhesion, snow masses are formed, also known as snowflakes.

Residents who feel unwell during the cold wave, especially the elderly, pregnant women, infants, patients with cardiovascular and cerebrovascular diseases, patients with respiratory diseases and other vulnerable groups, should go to the hospital in time. If you have any public health and health problems, please call the public health hotline 12320. Due to the lack of warm-keeping measures, southern residents have a poor sense of cold protection and are prone to frostbite or even freezing to death. They should pay attention to the weather forecast and buy clothes and warm things in time.

Although residents in the northern region have corresponding warm-keeping facilities, when the cold wave comes and the temperature drops suddenly, the warm-keeping protection should be further strengthened to prevent carbon monoxide poisoning. Residents in extremely cold areas should pay attention to the weather forecast, keep warm indoors and by themselves, prevent carbon monoxide poisoning, prepare enough warm-keeping supplies and food in advance, and try not to go out. Low-temperature rain and snow freezing refers to natural phenomena such as low temperature, snow, ice and freezing rain formed in winter because the long-term average temperature is lower than the average temperature for many years. The fundamental reason for the freezing of low temperature rain and snow in China is that the strong cold air in the northern Mongolian Plateau and Siberia quickly merged with the warm and humid air in the south, forming a wide range and strong rain and snow weather.

At the same time, due to the low average temperature, rain and snow quickly condense into a thin and transparent ice layer, which has a great impact on traffic, outdoor power supply facilities and crop growth. At the same time, low temperature, rain, snow and freezing weather will aggravate the symptoms of chronic diseases such as chronic low back pain, rheumatoid arthritis, chronic bronchitis and asthma. The occurrence of low temperature, rain, snow and freezing will generally cause drastic changes in the weather. At this time, sub-healthy people and vulnerable people are more likely to induce and aggravate diseases.

Low temperature, rain, snow and freezing weather are harmful to middle-aged and elderly people, pregnant women, children and cardiovascular and cerebrovascular diseases (such as stroke and coronary heart disease). ), patients with chronic diseases (such as chronic low back pain, rheumatoid arthritis, chronic bronchitis, asthma, etc. ), people with depression and people with weak constitution. You need to pay more attention to keep warm at this time.
