There is a folk word called "Niankan'er", which generally refers to the end of the year of the sick and weak person, that is, around the cold winter month, if it is not well taken care of, it will be difficult to spend it safely. Therefore, every year, many elderly and infirm people die in winter. But if you cross this hurdle, the next year will be safe for more than half a year.

According to historical records, the five emperors of the Qing Dynasty, namely Shunzhi, Kangxi, Qianlong, Daoguang, and Tongzhi, also died in the waxing moon and the first month, and five emperors died in July and August. Is all this a coincidence, or is there something else hidden? The medical records in the Palace of the Qing Dynasty record that there are two main causes of death of qing emperors, one is smallpox, and the other is caused by dietary problems.
Smallpox is one of the oldest infectious diseases and one of the most mortal. It is highly contagious and severely ill, and anyone who has not received smallpox or has been vaccinated against smallpox can be infected. Since vaccinia virus and smallpox virus have the same antigenic properties, people can also obtain immunity against smallpox virus after vaccination against cowpox.
The vaccinia vaccine was not discovered until after the eighteenth century. Coupled with the strong resistance of smallpox virus, it can fight dryness and low temperatures, so winter is the peak of smallpox outbreaks. The Shunzhi Emperor and the Tongzhi Emperor died because they had smallpox. Of Kangxi's sons, as many as twelve died of this disease. It is not surprising that emperors of the Qing Dynasty would die of smallpox.
In the concept of many ancient people, vegetables and grains were all things that ordinary people ate, and princes and nobles, rich and noble families and emperors were all birds and animals that ate. These are animals, can they not be greasy? Moreover, the emperor's status is noble, and he does not eat or rarely eats vegetables, which leads to an unhealthy diet.
Some people say that eating greasy is not a big problem. But the problem is that the emperor not only eats greasy, but also does not love sports. Not to mention the low temperature in winter, the emperor does not like sports. Even in other seasons, the emperor did not like to exercise. First, because the emperor was busy with the government and had to deal with many major state affairs, he did not have time to go out and exercise. Second, because the emperor's status is noble, there are carriages and palanquins and other means of transport to take when going out, basically they do not have to walk by themselves.
The emperors of the Qing Dynasty ate fat and did not like to eat vegetables, and coupled with their inactivity, the blood vessels in the cold winter were supposed to contract to maintain body temperature. And their eating habits once again caused the blood vessels to constrict, and the blood supply could not be supplied, so many emperors had accidents in the winter and eventually died.
Until now, many people have also died in the winter. Judging from the reason why the Emperor of the Qing Dynasty died in the winter, it is good to pay more attention to diet and go out to exercise more this season!
