1, keep warm and protect Yang Qi: It is cloudy in winter, mainly protecting yin essence, so it is advisable to drain less body fluids. Therefore, it is necessary to "dispel the cold and warm it" in winter to prevent the cold from invading. But don't warm up suddenly and violently, especially avoid thick clothes and fur, getting drunk with fire, roasting your abdomen and back, and suddenly warming up and sweating. Clothes should increase with the decrease of temperature, keep warm and close to the skin, so as not to make the skin sweat, and protect the yang from infringement.

2, daily life should go to bed early and get up early: in the snow season, everything is hidden, and health care should also conform to the laws of nature and work hard on the word "hidden". It is advisable to go to bed early and get up early in daily life, and exercise restraint, especially in the south, to keep the lungs clear. The temperature difference between morning and evening is large, so the elderly should be careful about their lives and exercise properly to enhance their adaptability to climate change.

3, foot massage: be sure to keep your feet clean and dry, wash your socks frequently, wash your feet with warm water every day, and massage to stimulate foot acupuncture points. Walk for more than half an hour every day to exercise your feet. In addition, it is also important to choose a pair of comfortable, warm, light and hygroscopic shoes.

4. Drink plenty of water: Although sweating and urination are reduced in winter, cells in the brain and various organs of the body still need water to nourish them to ensure normal metabolism. In winter, the daily water supply should not be less than 2000 ~ 3000 ml.
