Why are my soles cold in winter or summer?

It is common for some people to feel cold hands and feet in winter. This is mainly because the natural temperature drops, the yang is insufficient, the human body itself is also insufficient, and the body appears yang deficiency. In addition, due to the cold weather, the ability of vasoconstriction and blood return will be weakened, which will make the blood circulation of hands and feet, especially fingertips, not smooth, which is often called "poor circulation of nerve endings", resulting in the feeling of cold hands and feet. This situation generally happens to women, especially women over middle age. Mental workers are more likely to have cold hands and feet than manual workers, but they are rare among healthy young men. Cold can make people's whole body or local blood circulation poor, or blood circulation in limbs is blocked, which will lead to cold hands and feet. Cold hands and feet are often cold for a long time, which can be called "cold syndrome". Chinese medicine theory believes that this is a reaction of qi deficiency, qi stagnation and yang deficiency. Women are more likely to have cold hands and feet during special physiological periods such as menstruation, pregnancy and childbirth because of their weak body.
