Many girls get cold feet in winter. Cold hands and feet for a long time are not only uncomfortable, but also prone to chilblain and other diseases. 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. The nursing plan of cold hands and feet is the most effective way to soak your feet every day. 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 jogging, brisk walking, rope skipping, 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.

In order to increase calories and improve cold hands and feet, you should deliberately supplement them.

Japanese scientists found that hesperidin extracted from orange peel, added to drinking water, can significantly improve the phenomenon of cold hands and feet of women. 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.
