In late autumn, if you want to "rest", you must know these →

Recently, many places in Beijing, which has entered late autumn, have seen an increase in temperature in the afternoon, even to 27°C. Many friends have taken out their forgotten short-sleeved shirts again. According to the observations of more than ten observatories in Daxing District, Fengtai District, Haidian District, etc. in Beijing, we were surprised to find that the highest temperature in the afternoon of the 25th of this month actually "crushed" the highest temperature in late October. However, many citizens will say that it is still very cold to go out in the early morning. It is the most difficult to rest at this time of warm and cold weather.

Why does it suddenly get warmer in late autumn?

Recently, the temperature in northern areas such as Beijing, Tianjin, Shandong, Hebei, Henan, and Inner Mongolia Autonomous Region has been particularly high, while the temperature in southern areas such as northern Hunan and Guizhou has also been higher than in previous years. Since the 22nd of this month, the average temperature across the country has been 4℃~7℃ higher than the same period of previous years.

The main reason for the high temperatures in various places recently is the weak cold air. Since the polar vortex (also known as the "circumpolar circulation" or "circumpolar vortex", which is a large-scale high-altitude cyclonic circulation around the South Pole or the North Pole that accumulates cold air) is located relatively northward, the cold air is significantly weaker than usual. In addition, most parts of my country have been controlled by the northwest airflow behind the westerly trough for a long time. On the one hand, this has caused the main sinking airflow behind the trough, resulting in adiabatic warming in the near-ground layer. On the other hand, under this circulation situation, the weather is fine, which is conducive to solar radiation warming, causing the temperature to rise.

Generally speaking, the cold air should have entered its active period after mid-October, especially in the northern region. Due to the influence of the active cold air from the north, the temperature would have dropped significantly compared with the previous period. However, this year the cold air was significantly weaker, resulting in significantly higher temperatures. Currently, a total of 237 national meteorological stations have broken the historical extreme of the highest temperature in late October, which is still relatively rare.

How to rest when there is a big temperature difference between day and night?

1. Eat a mild and warm diet

In late autumn, the dryness has not completely subsided. At the same time, the killing air comes with the cold air. For people with weak lungs, they should still pay attention to prevent the harm caused by cold and dryness. Cough is the most common manifestation of lung damage in autumn. When dryness and wind and cold are present, dry cough with little sputum, dry throat and itchy nose are the most common discomfort symptoms before and after the frost.

Chinese medicine for treating coughs during this period is mainly warm but not dry, moist but not cold, so as not to damage the body's body fluids, or be too greasy and block the flow of qi. In daily diet, we should also pay attention to eating more neutral or slightly warm foods, and not eat spicy, hot and dry foods just because the outside temperature is low. Although these foods can resist the cold, they will promote dryness and damage the body's body fluids, which is not good for health.

Common mild and warm foods include glutinous rice, sorghum, corn, cowpea, lentil, cabbage, mustard, carrot, lily, yam, hawthorn, etc. They can be eaten appropriately in late autumn to achieve the purpose of mild and warm.

2. Add or remove clothes in time in daily life

Although the temperature is high during the day, it is still relatively low in the early morning, and the temperature difference is large. Therefore, the public should pay attention to weather changes in time when traveling (especially to work, school, commuting, outdoor work, etc.), and add or remove clothes in time to prevent colds.

It is especially important to keep your feet warm during this period, because the feet are the important starting and ending points of the twelve meridians, and the intersection of the three yin meridians and three yang meridians is on the feet. The twelve meridians play an important role in running qi and blood and regulating the functions of the internal organs. At the same time, because the feet are far away from the heart and have less blood circulation, the feet are very sensitive to temperature changes, especially to cold stimulation. This is what "cold starts from the feet" means. Keeping your feet warm is very important for maintaining blood circulation and temperature, and preventing colds.
