My hands and feet will be cold when the weather is cold. Why? What should I do?

The main reason of cold hands and feet is that the metabolism of blood slows down in winter, and the low temperature makes blood vessels contract, which weakens the blood reflux ability and makes the blood circulation of hands and feet, especially the fingertip and toe, and the terminal nerve circulation not smooth. Chinese medicine believes that it is easy to be afraid of cold in winter because its constitution belongs to yang deficiency and qi and blood deficiency. Therefore, in addition to eating mutton, dog meat and other foods with the function of warming yang, we should also appropriately increase the intake of yam, black-bone chicken, hawthorn, fungus, pig blood and other foods with the functions of benefiting qi, nourishing blood and promoting blood circulation. Nursing plan for cold hands and feet Soak your feet every day: Soaking your feet is the most effective method. Add hot water of about 40 degrees to the deep basin, so that the water overflows the ankle. Soak for about 20 minutes, you will feel whole body fever, indicating that after the blood circulation is smooth, the body begins to heat up. If you rub your feet while soaking them, the effect will be better. Aerobic exercise: jogging, brisk walking, skipping rope, disco dancing, playing Tai Ji Chuan, etc. It will make all parts of the body move and promote blood circulation, but don't exercise too much. High-intensity exercise and excessive sweating will "release yang" and have the opposite effect. Wear cotton socks: cotton socks are not only soft and comfortable, but also absorb sweat from feet, keeping your feet dry and comfortable all day. Supplementing calorie food: In cold weather, in order to increase calories and improve cold hands and feet, it is necessary to supplement them deliberately. It is cold in winter in the north, so you can supplement warm foods, such as beef, mutton or dog meat. The mild climate in the south is more suitable for adding sweetness, such as chicken, duck and fish. And try to eat less cold fruits such as pears and water chestnuts. Get enough sleep: get at least 6 hours of sleep every day. Adequate sleep is conducive to the storage of yang and the accumulation of yin essence. Massage hands and feet: You can often rub your hands and feet when you have time to improve the microcirculation of peripheral blood vessels and have the effect of warming your hands and feet. Treating cold hands and feet with orange peel: Japanese scientists have found that hesperidin extracted from orange peel can obviously improve the phenomenon of cold hands and feet of women by adding it to drinking water. In the experiment, the researchers asked 10 women with cold hands and feet to drink hesperidin water and 10 patients to drink pure water. After two hours, let them soak their hands in cold water 1 min, and then test the recovery of blood flow and temperature. The results showed that the hand temperature of a group of people who drank pure water did not recover after 40 minutes, while that of a group who drank hesperidin water only recovered to the temperature before cold water immersion in 30 to 35 minutes, and the blood flow of fingertip capillaries was obviously improved. Eating black food, such as black rice, black dates, black beans, black sesame seeds, black fungus, black buckwheat, laver, cocoa, etc., can promote blood circulation, regulate gastrointestinal function, and improve fear of cold.
