Recently, temperatures have dropped in many parts of the country. Some people are eager to find seasonal clothes, while others firmly adhere to the principle of "covering up in spring and freezing in autumn". Who should we listen to when we are about to enter the season of 'dressing randomly'? Why do we need 'autumn frost'? Is there a scientific basis behind the saying 'spring covers and autumn freezes, no miscellaneous diseases'? In autumn and winter, as the temperature decreases, it is appropriate to increase or decrease clothing to achieve the effect of adapting to the temperature and improving immunity. ”Wang Zhizhong, director of the outpatient department of the Aerospace Center Hospital under General Technology Group, said in an interview with China News Health reporters. Experts emphasize that in fact, when autumn gradually cools down, moderate cold resistance can indeed stimulate the body to produce more immunoglobulins and improve its defense against pathogens. In addition, the mild cold stimulation in autumn can enhance the defense ability of the skin and mucous membranes. However, adding thick clothing too early can lead to poor sweat discharge, making it easy to catch a cold and respiratory infections. From the perspective of traditional Chinese medicine, in autumn, the yang energy is restrained, the temperature gradually drops, and the body's yang energy gradually converges towards the body. Proper exposure to coolness can promote the circulation of qi and blood, and avoid premature closure leading to "internal heat and external cold". Autumn dressing rules: So, to what extent should the so-called "autumn frost" be frozen? How to master the standards for adding or removing clothing? Wang Zhizhong gave the following suggestions: 1. When the temperature is above 20 ℃, the speed of increasing clothing can be relatively slowed down, and the body's immunity can be improved through mild cold stimulation. When the temperature drops below 15 ℃ and lasts for more than two weeks, thick clothing should be added in a timely manner. 3. 'Autumn frost' should be measured as' warm hands and feet, slightly cool back '. During the 'autumn freeze', some parts should avoid catching a cold - the abdomen, ankles, and cervical spine must not be exposed to the cold. After catching a cold in the abdomen, not only will chronic problems such as diarrhea and pain occur, but women will also experience worsening menstrual discomfort symptoms. People with weak physical constitution who are prone to cold hands and feet should pay more attention to keeping their feet warm. These people are not suitable for "autumn freezing". Wang Zhizhong emphasized in an interview that not all people are suitable for "autumn freezing". The following groups should add clothing in a timely manner when cooling down: 1. People with cardiovascular and cerebrovascular diseases. The temperature changes greatly in autumn, which can cause the contraction of blood vessels in the skin and subcutaneous tissues, leading to an increase in blood pressure and blood viscosity, increasing the risk of cardiovascular and cerebrovascular diseases. Therefore, people with cardiovascular and cerebrovascular diseases should pay attention to keeping warm when cooling down. 2. People with gastrointestinal diseases are very sensitive to cold stimulation in the gastrointestinal tract. When cooling down, attention should be paid to protecting the gastrointestinal tract to prevent the recurrence of old diseases. 3. People with respiratory diseases such as chronic asthma, bronchitis, chronic obstructive pulmonary disease, and pulmonary fibrosis should pay attention to adding clothes in a timely manner to prevent colds. 4. In autumn, people with bone and joint diseases should pay special attention to keeping the affected area, especially the legs, warm and prevent the joints from getting cold. 5. Elderly population. 6. Pregnant and postpartum experts emphasize that adjusting clothing according to one's own physical condition and temperature is necessary to protect one's health while following natural laws.
