This is mainly caused by slow blood metabolism caused by deficiency of qi and blood, vasoconstriction caused by low temperature, weakened blood reflux ability, poor blood circulation of hands and feet, especially fingertips and toes, and poor peripheral nerve circulation. It means that your body is deficient in kidney and qi and blood. Pay attention to supplement nutrition and eat more foods that promote blood circulation, such as sesame seeds, peanuts, spinach, tofu, fresh fish, peppers, onions and garlic. Protein, fat, vitamin B 1, B2, amino acids and iron in beef and mutton can also improve cold hands and feet. Cold hands and feet are mainly caused by poor regulation of autonomic nervous function and thinning of blood vessels. Plus toes, knees, shoulders, fingers, etc. They are all joints with more exercise, less fat, less calories and less blood vessels, and they are more likely to feel cold. Due to physical weakness, it is more likely to cause cold hands and feet. Do more exercise to strengthen your physique! Do more aerobic exercise, jogging, playing Tai Ji Chuan, etc. It will make all parts of the body move and promote blood circulation! Be sure to pay attention to scientific and reasonable warmth.
