In the cold winter, due to the dry and cold climate, the blood vessels in the human epidermis contract, reducing the loss of heat, but it also leads to the slow blood circulation in the skin layer, the decline of the functions of sebaceous glands and sweat glands, resulting in a great decrease in the moisture and fat content on the skin surface. If the cold wind blows, the skin resistance will be greatly weakened. Therefore, the skin in winter is easy to become dry, rough, sensitive and even chapped. In terms of diet, you can eat more foods containing mucus, such as honey, sea cucumber, fungus, pear, tendon, etc., to increase the colloid content in the blood and increase the preservation of intracellular water.

1, how important is water to human body?

Water plays a role of "lubrication" in human body. Lack of water will increase the "friction" between joints, organs, tissues and cells, and induce related diseases. Breathing needs the action of water. Only when the lungs are moist can oxygen be inhaled and carbon dioxide be discharged smoothly. If the "water supply" in the body is insufficient, breathing will be affected.

It is emphasized that in the winter when vitality is latent and everything is hidden, it is necessary to conserve energy and hide yang and yin. The specific method is to "go to bed early and get up late", ensure adequate sleep, pay attention to the warmth of the body, and avoid yang leakage.

2, pay attention to joint warmth

Because joints are mostly tissues with few blood vessels such as tendons and ligaments, the temperature is already low, and limbs are often exposed, which makes joints stiff and blood circulation poor, so the pain is not limited. Therefore, arthritis patients should strengthen their warmth in the cold winter. If you can soak your feet before going to bed in winter, you can not only promote blood circulation and dredge collaterals, but also soothe your nerves and help you sleep.

3. Keep indoor air circulation.

It is necessary to regularly open windows for ventilation, maintain indoor air circulation and reduce bacterial growth.

4. Pay attention to the temperature difference to prevent colds.

Due to the extremely low temperature in the morning, we should pay attention to going to bed early and getting up late in life to avoid catching cold.
