A bitter wind accompanied by a strong snowfall opened the curtain for this year’s cold season on January 5. -The temperature of about 10℃ labeled the cold season as “three nine cold days”. Usually from the small cold to the big cold should be the coldest season of the year, in this season do not stay in the heated house all day because of the cold closed doors and windows, every day when the sun rises to open the window ventilation is a mandatory homework; snow walking, bathing in the winter afternoon sun is also a special mood; know how to appreciate the surrounding people and the surrounding natural scenery is the key to emotional regulation. Usually small cold cold or not also foretells the coming year’s weather, such as “small cold weather hot, cold cold do not say”, “small cold not cold, Qingming mud puddle”, “small cold warm, the spring snow”, “small cold cold, the spring”. “small cold cold, stirring warm” and so on. Chinese people in many years of practice, summed up the small cold big cold and small summer and summer weather correspondence. For example, “small cold and big cold does not snow, small summer and big summer field cracking”, “small cold without rain, small summer will be dry” and so on. The weather is getting colder and colder, warmth is the key. In addition to moderate exercise, you should also eat some warm food, such as meat stew with some fennel, cumin, cinnamon and other warm spices, like to eat spicy can also be full of spicy hot pot mouth, because Chinese medicine believes that “spicy warm in addition to the cold”. In addition to a reasonable diet, we also need to pay attention to the disease that is prevalent in this season – eczema. Recently, there are many patients with eczema recurrence in the clinic, and patients are very concerned about why eczema will worsen in winter. That is because “cold is yin” and “wet is yin”, this season the human body yang storage within the beginning of life, yin outside and cold corresponding, more fuel for the sprouting of dampness, in addition to eating protein fat and other high-calorie things in winter, easy to produce internal dampness, internal dampness is also aggravated Guest in the skin of the external wet, so that the rash aggravated. Modern medicine believes that most patients prone to eczema have a genetic background and are allergic to sudden changes in the environment such as a sudden drop in temperature in winter, especially in young children, teenagers and the elderly. The affected areas include the face, neck, elbows, knee pits, dorsal side of the limbs, palms and feet, etc. The affected areas may show red rashes, thickened and rough skin. The disease is recurrent and patients often scratch their bodies due to itching, which not only hinders their appearance, but also causes sleep disorders or affects outdoor sports and quality of life, and has a negative impact on their psychological well-being. Currently, the main drugs used to treat eczema are hormonal topical drugs, which are prone to many adverse reactions after long-term use. The long-term use of the face is likely to lead to capillary dilation, the face is like rosacea, once you stop using the drug is very uncomfortable, a vicious circle, the face more red, and easy to cause skin atrophy. If used on a large area of the whole body for a long time, the hormones can be absorbed into the body and cause the same systemic side effects as eating hormones. Recently, a new type of drug called topical immunomodulators has been widely used at home and abroad. These hormone-free drugs have the same anti-inflammatory effect as hormones, but without the side effects of hormones, and can achieve good therapeutic effects in a short period of time and quickly control the symptoms of hormone-dependent dermatitis and eczema. But in order to eradicate eczema, both internal and external adjustments must be applied. Chinese medicine can classify eczema into damp-heat type, wind-heat type and blood deficiency and wind-dry type through whole body examination. Different types of eczema can be treated with different internal and external prescriptions in order to achieve good results.
