Keep in good health in summer to prevent sweating due to "wet cold" in summer, which is called "draining" by Chinese medicine, that is, the skin pores are open; On the other hand, in summer, the yang is abundant, and the yang in the body is relatively weak, and the ability to be lower than the exogenous evil decreases. In this case, the evil of cold and dampness is more likely to invade the human body and harm the skin, gastrointestinal tract and muscles. In addition, it is in an air-conditioned environment for a long time in summer, and the temperature is lower than 26℃. In addition, the clothes are thin, revealing shoulders, umbilicus, waist and knees; The temperature difference between indoor and outdoor is large, and there is no transition from high temperature to low temperature, or after sweating, you can take a shower with cold water and blow it with a big fan, which is called "sweating when the wind blows" in Chinese medicine. Excessive consumption of iced, frozen cold drinks and fruits; Some people like to enjoy the cool outside at night and sleep on the cold concrete floor, 86tcm. And so on. These are all opportunities to be vulnerable to cold and dampness. Yan Xia zhishi feels the diseases caused by cold and dampness. According to the different clinical symptoms, TCM generally has corresponding disease names such as "Yin-summer heat" and "Bi syndrome". Heat in cloudy and midsummer is often manifested as fear of cold, no sweating, loss of appetite, diarrhea and so on. If the evil of cold and dampness guards the meridians of the limbs, it can be seen that the muscle joints are cold or sore, and even the activities are obviously limited. In addition, for women, the evil of cold and dampness can easily invade the human body from below, leading to many gynecological diseases. Chinese medicine believes that the summer heat is the main command, and the human yang will also rise wildly, which is not only easy to damage vaginal fluid, but also easy to consume the human yang. In this way, in summer, the spirit of the sun is often partially lost because of reckless actions and being injured by the heat. At this time, if the evil of cold and dampness, that is, yin qi, takes the opportunity to invade the human body, then the weak yang in the human body will be unable to resist and breed diseases. Therefore, the method of "nourishing yang in spring and summer and nourishing yin in autumn and winter" put forward by Chinese medicine is very insightful. Therefore, despite the hot summer, we should always prevent the evil of cold and dampness from invading the human body. So, how to prevent the invasion of cold and dampness? It is fundamental to keep the yang exuberant at all times. The view of "nourishing yang in spring and summer" is mentioned above, and there is also the view of "nourishing yang in summer due to winter illness", which is similar in essence. The so-called "nurturing" actually includes two aspects: "nurturing" and "protecting". Only by combining conservation can the yang flourish. "Raising" means raising at ordinary times. Specifically, in terms of diet, we do not advocate eating spicy or cold products, because spicy heat is easy to hurt yin and cold is easy to hurt yang. Summer food should be light and easy to digest, and staple foods such as rice and flour are essential. At the same time, fish, lean meat, eggs and other foods rich in protein, fresh vegetables, fruits and other foods rich in minerals and vitamins should also be appropriately increased. For example, yang deficiency, in addition to indigestion caused by weak stomach qi, also has the performance of kidney yang deficiency such as fear of cold, which can be adjusted by taking appropriate Chinese medicine prescriptions when necessary. There is a simple way to prevent summer cold and dampness. Just drink ginger tea every day. The so-called "nurturing" is internal, and the external "protecting" is to ask us not to be too hot and greedy. Don't sleep directly outdoors or indoors at night. The air conditioning temperature is too low and the electric fan is too strong. Don't sit in a dark and humid place for a long time. Don't eat a lot of iced food or drinks. Don't take a shower with cold water immediately after sweating. Don't delay changing the mat when the summer heat gradually decreases in late summer.
