It’s cold, and these parts of science can’t be ＂frozen＂
Recently, cold air strikes frequently, the north is getting colder and colder, and the south is also "autumn overnight". On weekends this week, the lowest temperature in Wuhan may come to single digits, only 9℃! Imagine that in just a few days, from summer to autumn, and then to winter, the cold air in season is "delivered" one after another. It is really a season, from short sleeves to windbreakers to cotton-padded clothes, and friends have to change their clothes quickly.
However, as the saying goes, "Spring covers autumn, and no miscellaneous diseases are born". Proper freezing will help the body gradually adapt to the cold and improve the body’s disease resistance. Can everyone "freeze in autumn"? When is the best time to add clothes? Xiao Qiming, chief physician of respiratory medicine of Xiangya Hospital of Central South University, Sun Qiwei, deputy chief physician of the Center for Prevention of Diseases of Xiyuan Hospital of Chinese Academy of Traditional Chinese Medicine, and Wang Xiao, deputy chief physician of the Department of Rheumatology of Longhua Hospital affiliated to Shanghai University of Traditional Chinese Medicine, will teach you to get cold scientifically without getting sick.
Why is freezing healthier in autumn?
Spring is born, summer grows, autumn harvest and winter storage, and man and nature are integrated. When I go to Qiu Lai in summer, the sun’s spirit gradually converges and the temperature gradually drops, which is a transitional stage from hot to cold. Although the temperature begins to drop, if you put on a thick cotton-padded coat too early, you will not be able to exercise against cold air, which will reduce your cold-proof ability and is not conducive to the self-regulation of human resistance. In the really cold season, once the nose and trachea are attacked by cold air, the blood vessels inside shrink because they can’t resist, which reduces the blood flow and weakens the antibacterial ability. Bacteria hiding in the nose or trachea take the opportunity to move, causing symptoms such as cough, sneezing, runny nose and fever, which makes people sick.
Therefore, it is necessary to freeze properly in autumn and gradually improve the body’s ability to resist cold and disease. This is a subtle exercise that can improve people’s physique invisibly. On the other hand, autumn is the season of nourishing yin. If you wear too much clothes and cover them too hot, it will encourage yang spirit, which is not good for maintaining the balance of yin and yang, and will also cause diseases.
Therefore, when the temperature is a little cold in autumn, don’t add clothes too early and too much, so that your body will feel a little cold, gradually adapt to the cold, improve your disease resistance, and it is healthy to "freeze" your body properly.
Boundary of autumn freezing temperature: 15℃
Autumn freezing is good for health, but when there is strong cold air activity and the temperature drops sharply, we should add clothes to keep warm in time and properly. At this time, if we insist on "autumn freezing" blindly, it will be counterproductive. China has a vast territory, and the process of entering autumn is inconsistent in different places. Under what circumstances should we add clothes?
The answer given by experts is: Take 15℃ as the standard, if the temperature drops below 15℃ in autumn and lasts for more than two weeks, you can put on clothes for autumn and winter.
In addition, scientific autumn freezing has three principles:
When the temperature drops slightly, healthy people can not wear thick clothes immediately, but add clothes and pants as late as possible or gradually to enhance their adaptability to the temperature drop.
Old people, children or people who are physically weak should not blindly pursue autumn freezing, but should "stop the heat" to avoid the hot air spreading outside, the yang spreading outside and the wind evil entering the body.
When the temperature drops sharply, you should not blindly pursue autumn freezing, otherwise you will get sick easily.
Four types of people can’t stand the autumn freeze.
Autumn freezing is not suitable for everyone. The following groups of people are more vulnerable to cold than the average person. It is best to add clothes in time according to the temperature and physical feeling.
A frail old man
There is a large temperature difference between morning and evening in season change, which is the high incidence season of upper respiratory tract infections such as influenza. The respiratory muscles, diaphragm and ligaments of the elderly are atrophied, the elasticity of lungs and trachea is weakened, and the respiratory function is reduced. It is easier to catch a cold if clothes are not added in time.
Patients with cardiovascular and cerebrovascular diseases
After being stimulated by cold, the capillaries of the whole body contract, the peripheral resistance of blood circulation increases, and the blood pressure is higher than that in summer. Cold stimulation will make the myocardial ischemia and hypoxia that have already been diseased more serious. People with cardiovascular diseases should add coats in time to keep their chests warm to avoid myocardial infarction; In the past, elderly people with multiple cerebral infarction, cerebrovascular malformation or stenosis should pay attention to keeping their heads warm to avoid aggravating or inducing stroke.
Patients with rheumatism or rheumatoid diseases
Arthritis patients often feel pain and heaviness in their legs when the weather is cold. It is suggested to wear warm knee pads on their legs to ensure the stability of the knee joint and promote blood circulation.
diabetic
Diabetic patients have poor local blood supply, and their blood vessels are stimulated by cold air, which is prone to vasospasm, further reducing the blood supply to muscle tissue and aggravating local numbness of hands and feet and low back pain. When the weather changes greatly, the elderly with "three highs" should strengthen the monitoring of blood pressure, blood sugar and blood lipid, and pay attention to the changes of their condition at any time.
Don’t freeze these parts of your body.
Head and neck: There are abundant nerves and capillaries in the head and neck. Autumn wind attacks easily lead to vasoconstriction of the head and neck, which is not conducive to blood supply to the brain, and it is also easy to cause a cold with lung symptoms.
Shoulder: The tissues around the shoulder joint are relatively fragile. After a long cold, it is easy to be attacked by "wind, cold and dampness", which will cause shoulder pain. Traditional Chinese medicine believes that scapulohumeral periarthritis is caused by cold in the shoulder, and the chest and shoulder joints are stiff after illness, which seems to be frozen, so it is called "frozen shoulder" and "shoulder coagulation". Sometimes the pain will spread to the arms and hands, and even the pain is unbearable.
Abdomen: There are many organs in the abdomen, and many important meridians pass through, such as spleen and stomach meridians and liver and kidney meridians. Renchong and Du meridians start in the abdominal cavity. Cold and cold qi is also easy to invade the human body from the abdomen. Being cold here will cause stagnation of qi and blood in the abdominal meridians, such as stimulating the intestine and causing diarrhea; People with a history of stomach trouble are prone to stomach pain; Women who catch cold in the lower abdomen are easy to induce dysmenorrhea and irregular menstruation. The belly button part is the longevity hole of the human body, so it should be protected.
Feet: "Cold comes from the feet", the feet are the parts of the whole body that are most afraid of cold, and the meridians of the kidney and spleen and stomach all originate from the feet. However, because the feet are farthest from the heart, the blood flows the longest "distance". If the feet are cold, the blood flow will be stagnant, and the blood supply in the whole body will be insufficient, which will easily cause the capillaries in the relevant parts to contract, and the pathogenic factors will easily take advantage of it to enter the organ function and then be damaged. Soaking feet with hot water can relax muscles and promote blood circulation, generally at a water temperature of about 40 degrees Celsius (not hot).
Excessive fear of cold
It’s the body calling for help.
Our bodies can quickly perceive the warmth and coldness of the surrounding environment, and protect our bodies from physical injuries caused by excessive cold and overheating. If you are more afraid of the cold than the average person, or you are still afraid of the cold when you wear a lot of clothes, it may be that your body is "calling for help".
The stomach is afraid of cold — — cold syndrome of the stomach
Eating a little cold food and drinking some green tea will make you feel bloating and stomachache, which may be related to overeating and getting cold in the stomach. If it happens repeatedly, it may be a sign of spleen and stomach weakness and yang deficiency.
Tips: Try to choose ingredients that are mild in taste and beneficial to qi, such as longan meat, medlar, jujube, etc., and avoid cold, wet and greasy foods.
Legs are afraid of cold — — chronic rheumatism in the leg
In addition to being affected by cold and humid environment, "old cold legs" have a common cause — — Joint, ligament and muscle strain are mostly caused by long-term physical labor, improper walking posture, aging and other reasons.
Tips: Moxibustion can be applied to the points around the knee joint, such as Zusanli and Dubi, every time for 5-mdash; Ten minutes.
The waist is afraid of cold — — Strain or disc herniation
Cold and dampness blocking the waist can lead to cold waist. Waist injury, lumbar muscle strain, lumbar disc herniation, etc., lead to the obstruction of yang qi operation, but also show that the waist is afraid of cold.
Tips: Lumbago can be used for hot compress on the waist; Morning is the time when the body’s yang is gradually filled with the weather, which can increase outdoor activities; You can practice Wuqinxi, Baduanjin and Tai Ji Chuan at ordinary times.
Cold hands and feet — — Yang deficiency
Cold hands and feet are more common in people who have been dieting for a long time or have bad eating habits, which is mainly caused by the lack of nutrients and the lack of material basis for yang. If you don’t pay attention to it, your physical fitness will further decline, leading to more serious problems.
Tips: Chinese medicine believes that "movement leads to yang". Usually, you should pay attention to exercise, get more sunshine, and eat regularly for three meals a day. You can add 15 grams of safflower and 30 grams of Artemisia argyi to soak your feet before going to bed to promote blood circulation and dispel cold.
