Loggers living in the northeast forest area have the saying that drinking alcohol will increase the body's heat and play a role in keeping out the cold. Hebei, Shandong, Shanxi and some rural areas in the south of the Yangtze River also have this statement. In fact, this is all wet. After drinking alcohol, people's blood circulation will accelerate and they will feel warm all over. This is the result of alcohol prompting the human body to emit primitive heat energy. After drinking alcohol, a lot of heat escapes from the body, which makes people feel cold all over, leading to a cold after drinking.

Step 2 sleep with your head covered

When the room temperature is lower than 16 degrees Celsius, it will be a little cold to sleep at night, so some people will sleep with their heads on the bed in winter and feel warmer. In the south without heating facilities, or in the suburbs and rural areas with poor heating facilities, sleeping with your head covered has become a way of heating. This is a very unscientific way to keep warm. We need to inhale oxygen and exhale carbon dioxide. If the air circulation in the bed is too poor, oxygen will be less and less, but carbon dioxide and unclean gas will accumulate more and more. So many people who are asleep will feel groggy and exhausted after waking up. This is the result of poor breathing caused by unclean air.

Step 3 Wash your face with hot water

Go home at night in winter, wash your face and steam it with a pot of steaming water? It will make people feel very comfortable. This is because steaming heat blows open the fine pores of the face and promotes microcirculation. But it is not advisable to wash your face with hot water in the morning, because under the stimulation of cold air, people's sweat glands and capillaries are contracting. It expands rapidly when it meets hot water. Go out to work immediately after washing, get in touch with cold air quickly, and the capillaries contract rapidly. Such capillary contraction can easily cause wrinkles on people's faces.
