The end of the year is the ventilation season. Why is the mortality rate often the highest in ventilation season?

Temperature, light, etc. British research points out that this situation is usually caused by many reasons, some of which are obvious, such as cold weather; There are also some subtle issues, such as genetic problems; Psychological fluctuations will also have a major impact on this.

The low temperature led to the outbreak of disease. Zhou Rongbin said that the correlation between cardiovascular and cerebrovascular diseases and seasons has long been confirmed. As early as the 1920s, British researchers followed 1.9 million British government civil servants aged 40-85, and found that the mortality rate was related to the temperature. Blood pressure and mortality in cold season are significantly higher than those in hot season. Surprisingly, influenza was not the main "killer" in May 438+10. Tim, head of Scottish national records? Ellis explained that in winter, only a few of the increased deaths were caused by simple flu, and most of them died of acute pneumonia, coronary heart disease and stroke.

Lack of light leads to depression. The National Mental Health Association of the United States pointed out that every winter, due to the reduction of light, the number of patients with depression increased significantly, even about 10% more than usual. The American Academy of Family Medical Students found that the symptoms of depression in winter usually begin at the turn of autumn and winter, reach the peak in June and February of the following year, and will not be relieved until spring. British researchers further explained that people expect depressed mood and bad situation to get better in the new year, so the suicide rate usually drops in June+February of 5438. However, after entering the new year, everything did not get better as expected. Extreme depression will eventually lead to the rebound of suicide rate in June 5438+10, which psychologists call "delayed effect". From 65438 to 0973, a study by new york State University showed that the probability of people celebrating their birthdays was significantly higher than other days. This shows that if you have a strong psychological expectation, you can continue your life after these special days even if you are seriously ill.

Disrupt normal life in case of festivals. Zhou Rongbin said that in addition to the global holiday New Year's Day, China's traditional festival Spring Festival often appears at the end of 1. During the festival, people's daily life, diet and exercise rules will be broken, and the emotional fluctuations during the Chinese New Year increase the possibility of basic diseases. In addition, people tend to stay away from hospitals and go home for reunion on holidays. Some diseases can be put off until the Spring Festival. If you are in the hospital, leave if you can, and never stay in the hospital. However, it is impossible for illness and physical changes to follow the holiday, and this mentality will inevitably lead to the aggravation or attack of the disease.
