The skin is the largest organ of the body and has barrier, respiratory, secretory, regulatory, and immune functions. Currently there are more than 30 categories of dermatological diseases officially named, and as many as 1700 species, a large proportion of which have unknown causes and are difficult to treat and prone to recurrence. Some skin diseases have gender differences in their onset, and also have a certain age and seasonality of predilection. For example, melasma and lupus erythematosus are more common in women, acne is more common in adolescence, and summer is the season for allergic skin diseases, light skin diseases, sweat disorder skin diseases, and microbial infection skin diseases. There are many dermatology patients who ask: Why is my skin disease so difficult to treat? What is a good or radical cure? In fact, this question has been plaguing medical practitioners as well. The reason why some skin diseases do not heal repeatedly is that the cause is complex, the pathogenesis is unknown, and there is no effective drug for the cause; secondly, the occurrence, development and regression of the disease are affected by a combination of environmental, seasonal, dietary, emotional, genetic, endocrine, physical, immune and other factors. For example, in summer, high temperature, high humidity, strong sunlight, plants and animals in the environment are in a vigorous reproduction period, coupled with a large amount of human sweating, increased exposure of the skin and other reasons, will make the infectious and allergic skin diseases significantly increased; like to eat greasy, spicy, sweet food, but also prone to inflammatory, pruritic skin diseases; ichthyosis and other belong to congenital genetics and so on. In summer, women should pay special attention to the protection of the skin, how to prevent ultraviolet rays from killing, to avoid “photoaging”, to prevent the production of wrinkles, such as this kind of topic is not shared with you. Here I would like to remind you that your skin is also a psychological organ. Physiologically speaking, in embryonic development, the skin and the nervous system “share the same family”, so psychological factors can affect the skin. When people are happy, they will be “happy”; when they are afraid, they will be “as pale”; when they are anxious, they will be “sad”; when they are ashamed, they will be ” red face” …… these are the normal reflection of the mental state on the skin. The excessive changes in mood, that is, the increase in psychological baggage, can lead to a variety of skin diseases. This is because tension, anxiety and other emotions can cause the body stress response or even endocrine dysfunction, promoting the release of mediators such as bradykinin and histamine from blood vessel walls or tissue cells, which in turn affects skin vasoconstriction, dilation, sweat gland, sebaceous gland secretion, and even stimulates keratin formation and cell proliferation. According to Chinese medicine, anger hurts the liver, sorrow hurts the spleen, and thought hurts the heart. Many examples can be given of skin diseases triggered and aggravated by psychological factors, stress, depression, impatience, anger and other bad emotions. For example, if the liver is not comfortable, it is easy to suffer from chloasma; being competitive and having a high desire often makes one more stressed and more prone to heart fire and liver fire, which are important causes of acne, neurodermatitis, sweat rash and other diseases. At all times, a calm mind and good psychological quality are important factors in preventing diseases and improving conditions. We remind all women to control their emotions when the summer heat arrives, wave goodbye to negative emotions, and let their skin refresh for the summer.
