If you cover your body in spring and freeze in fall, you won’t get any miscellaneous diseases. I believe that many people have heard, but do you really understand this saying? How to scientifically understand the “autumn freeze”? After the weather turns cool in the fall, the phenomenon of rising temperatures occurs from time to time, commonly known as the “autumn tiger”. Therefore, if you add too much clothing too soon, you will easily catch a cold due to heat exhaustion once the temperature rises and you sweat and catch wind. Weather from hot to cold is a gradual process, some people rush to the fall to put on a lot of clothes, and even a little bit of cold to wear cotton, this practice is not appropriate. Autumn should be frozen, clothing should be added slowly. Therefore, the “autumn freeze” helps to exercise cold tolerance, in the environment of gradually lowering the temperature, after a certain period of time exercise, can promote the body’s metabolism, improve the body’s heat production efficiency, improve the ability to adapt to low temperatures. Human body temperature is generally around 37 degrees Celsius, body temperature is too high or too low, will have a negative impact on health. Now that autumn has begun, the weather turns cooler, appropriate less clothes to help exercise cold tolerance, enhance the adaptability to low temperatures. But “autumn freeze” is not suitable for everyone. Five types of people should not “freeze” 1, chronic lung disease patients, “autumn freeze” is also conditional. Under normal circumstances, the sunshine temperature in 15 ℃ ~ 20 ℃, people can reduce the appropriate clothing, but really close to the beginning of winter, we must add clothes in a timely manner. For patients with chronic lung disease, do not “autumn freeze”. This kind of patients, physical weakness, cold easy to take advantage of the weakness, resulting in trachea, bronchial tubes and other spasms, thus inducing bronchitis, bronchitis, bronchial asthma attacks or aggravation. 2, cardiovascular disease patients Chinese medicine believes that the heart of the blood, heart disease with the body of the Jin, blood running poorly related. Because of the Jin, blood, “get warm is line, get cold is condensed”, so the Jin, the operation of the state of blood by the external temperature has a great impact. Cold collects and attracts, cold guest blood, then the gas and blood stagnation, blood contracture, cardiac vein loss of nourishment, thus triggering fluctuations in blood pressure and ischemic cardiovascular events. So for cardiovascular patients, especially elderly patients, because of physical weakness, can not tolerate increased exercise to prevent cold and enhance the body’s resistance to the activities, so should not be “autumn frost. 3, gastrointestinal disease patients For gastrointestinal disease patients, including chronic gastritis, chronic enteritis, peptic ulcer, etc., should also be careful with the fall freeze. Generally since the fall to early spring the following year, are prone to ulcer season. The stomach is more gas and blood of the viscera, the cold is collected, after the cold gas and blood run poorly, it will be all the symptoms of the bee, or vomit or leakage, or bloating or pain. So if the autumn wind, or should add clothing in a timely manner, can not be too much “autumn freeze. 4, joint disease patients, “Autumn Freeze” to moderate, can not just freeze, especially on the important parts of the human body to strengthen the protection, such as the head, chest, abdomen, feet, neck, shoulders, waist, knees and so on. If the patient can not be relieved after adding clothes, you should seek medical attention to identify the causes of pain and discomfort, as soon as possible treatment. 5, diabetic patients Diabetic patients should not “autumn freeze”, one because “autumn freeze” easy to catch a cold. Long-term or irregular high blood sugar so that the body’s white blood cell phagocytosis ability to reduce the body’s resistance to decline, so the alternation of seasons, cold and hot easy to catch a cold. Second, to prevent patients from vasospasm. When the blood vessels of sugar patients are suddenly stimulated by cold air, vasospasm will occur, so that the blood flow is further reduced, and it is often combined with peripheral vascular neuropathy, which will lead to microcirculation disorders, easily caused by tissue necrosis and diabetic foot. In addition, like the navel, back and feet in early fall can not be frozen, but to cover a cover.
