Cover your back.
The back is the yang in the yang, which has the spine and back meridians to communicate with the heart and lungs. If stimulated by cold, the evil of cold can easily invade the human body through the back.
Cold stimulation of the back will affect local muscles or internal organs, thus inducing health problems. In addition to causing low back pain, it will also affect the muscles, joints and internal organs of the upper and lower limbs through the cervical and lumbar vertebrae.
Cover your stomach.
The navel and abdomen are different from other parts. There is no muscle and fat tissue under the navel, but there are rich blood vessels. And the abdomen is also the gathering place of stomach, spleen and intestine. If the abdomen catches cold, it is easy to cause gastrointestinal dysfunction and digestive system diseases such as vomiting, abdominal pain and diarrhea.
Cover your feet and knees.
The blood circulation of the lower body is much worse than that of the upper body, and the foot is the second heart of the human body, which is rich in nerve endings and vulnerable to the cold outside.
Once the feet or knees catch cold, it will reduce the disease resistance and cause diseases, such as arthritis, gout and bursitis. Therefore, when the temperature is low, you must wear thick pants, socks and shoes, and keep warm to prevent your feet and knees from catching cold.
