1 Avoid sleeping with your head covered.
It's very cold in winter, so people usually sleep under thick quilts. Therefore, the air in the bed is not smooth, and the air in the bed is turbid due to body odor, sweat smell, carbon dioxide in exhaled breath and harmful gases discharged from the intestine. If you sleep with your head covered, it will reduce the oxygen saturation in the body and seriously affect the physiological function of the large intestine. When I get up the next morning, I will have dizziness, listlessness, loss of appetite, memory loss and other symptoms.
Pay attention to skin moisturizing.
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's 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.
3 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.
