Precautions for severe cold solar terms:

1, go to bed early and get up late

"Great Cold" is the last solar term in winter. In terms of daily life, it is still necessary to conform to the characteristics of seclusion in winter, so as to go to bed early and play silly, and get up late to accompany us to travel. Going to bed early is to nourish the yang of the human body, and getting up late is to nourish the cold. On the other hand, there is an old saying that it is "freezing in cold weather, keeping out the cold and preventing the wind". In the cold season, in addition to keeping out the cold, you need to keep out the wind. Clothes should increase or decrease with the change of temperature, and keep warm.

Step 2 avoid cold radiation

In the severe cold solar terms, it is necessary to prevent the harm of cold radiation to the body. The specific measures are to stay away from cold walls and other objects, and sleep at least 50 cm away from the wall. If the temperature difference between the wall and the room is greater than 5℃, the wall is often wet, and even small water droplets may be formed. At this time, wooden boards or foamed plastics can be placed in front of the wall to block and reduce negative radiation, thus protecting the body from negative radiation damage.
