This is only a superficial phenomenon, and the specific reasons vary from person to person. Generally speaking, cold hands and feet reflect poor qi and blood circulation or weak qi and blood. It is possible that you have a cold constitution, and you can supplement some warm foods, such as brown sugar, ginger, red dates and donkey-hide gelatin. It may also be that you are sentimental, which leads to liver qi discomfort, and the liver is the part that runs qi and blood, which affects the smoothness of qi and blood in the whole body; It is more likely that you don't like sports, or that your job is mainly sitting. Also observe whether your cold hands and feet are accompanied by symptoms such as stomach cold and dysmenorrhea (I guess you are a lady:).

I have had very serious problems such as cold hands and feet, stomachache and fear of eating cold food. I was in pain. Since I insisted on practicing Tai Ji Chuan three or four years ago, these old problems have gradually withdrawn. My experience is that the whole body of 1 is a whole and needs to be adjusted as a whole; Strengthening exercise and regular work and rest are the best fitness methods; 3 The body should be stretched frequently, and the mood should also be stretched frequently.

I wish you the best of health!
