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.

Second, 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 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. #p# Subtitle #e#

Four taboos should be paid attention to in winter health preservation

Third, 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.

Fourth, the diet is warm but not dry.

Winter diet should grasp the principle of' appropriate lightness'. Because of the cold in winter, people like to eat warm food to resist cold evil. However, it must be noted that many modern people are over-nourished, and many people are prone to the phenomenon of rising virtual fire because of their hectic life and lack of sleep. Therefore, people who often have symptoms such as constipation, hemorrhoids, insomnia and acne should not make up for it. Patients with gastrointestinal diseases, gout, hypertension, diabetes, nephropathy and cardiovascular diseases should especially avoid eating spicy hot pot.

In winter, beware of heart attacks in middle-aged and elderly people. Because the elderly are old and have poor immunity, they have poor adaptability to the surrounding cold and exciting weather, so they are also the high incidence of cardiovascular diseases such as angina pectoris. Cold weather can make people's blood vessels contract, blood pressure rise and blood supply is insufficient.

Therefore, it is prone to arrhythmia, angina pectoris, and eventually lead to serious consequences such as myocardial infarction. The main manifestations of angina pectoris are chest pain and suffocation. Some patients also show toothache on one side and upper limb pain, and some female patients also show dyspnea and stomach discomfort, so they are easily overlooked. The most important thing for pregnant women in winter is to keep warm. Don't catch a cold accidentally, because pregnant women can't take medicine casually and feel uncomfortable. Soak your feet in winter, especially for pregnant women. Don't soak your feet in particularly hot water. The diet must be balanced, because there are few vegetables in winter, so constipation is very likely, so you must drink more warm water in your daily life. Pay special attention to dryness in winter, keep indoor humidity and drink more soup.
