When the weather is cold, my feet will sweat. What is the reason?

First, when the weather is cold, feet sweat, which is a bad peripheral circulation of the human body. This is a physical reason, you can exercise more to improve, and pay attention to keep warm. On the one hand, the arterial blood reaching the limbs (specifically the hands and feet) is less, and the accompanying nutrient oxygen is less, which greatly reduces the metabolism of this part of the body tissue and generates less heat, so the temperature is low and chills; On the other hand, venous blood reflux was blocked, and a considerable part of metabolites produced by limbs could not be brought to the kidneys for metabolism with blood circulation, so they had to be excreted from sweat glands, so they broke out in a cold sweat.

Second, exercise, dietotherapy, medicated diet, hot springs, massage, etc. We should do more in our daily life. Take more vitamin E. Vitamin E can dilate peripheral blood vessels, which is very helpful to smooth peripheral blood circulation, but the effect of vitamin E is slow, and it takes 3 months to take effect. Eat more foods containing niacin. Nicotinic acid is very helpful to stabilize the nervous system and circulatory system, and can also improve nervous tension, tension diarrhea and dermatitis, dilate peripheral blood vessels and improve cold hands and feet. Foods containing nicotinic acid include animal liver, eggs, milk, cheese, brown rice, whole wheat products, sesame, mushrooms, peanuts, mung beans, coffee and so on. Eat more nuts such as walnuts, sesame seeds and pine nuts; Vegetables such as leeks, carrots, kale, spinach, etc. ; Apricot, peach, papaya and other fruits are the best choice for diet. Other foods, such as beef and mutton, seafood, four gods, glutinous rice, brown rice, soybeans, tofu, sesame seeds, brown sugar and so on. It's all warm food, and people with cold hands and feet should eat more.

Third, people who are prone to cold hands and feet should avoid eating cold food, ice products or drinking cold drinks all year round, just to make the summer weather hot again and have a taste. Keep warm. Don't wear warm clothes less because you love beauty or are afraid of being laughed at for wearing too much. All kinds of warm-keeping measures, such as coats, wool hats, gloves, scarves, masks, sanitary clothes, socks, etc., should be fully worn in cold weather. Before you take off your coat, you must make sure that it is getting hot. Don't take off your warm clothes immediately because of mental irritability, nervousness, hot flashes, or fever after exercise. Don't wear too tight clothes either, because too tight clothes will hinder blood circulation.
