In the past two days, the temperature in most parts of the north has fluctuated significantly, and although spring has fully entered the south, many places have been experiencing continuous rain and feel damp and cool. As the saying goes, 'spring covers autumn frost', but 'spring covers' are not simply about' wearing more clothes'. How should we 'cover'? When will you hold on to it? Where is the key "covering"? Let's get to know each other. In the past few days since the launch of the national "Spring Cover" map, most of the country has been experiencing a warming trend. Due to the influence of cold air, there will be temperature fluctuations in the northwest, north, northeast, Huang Huai, Jianghuai and other areas from the 18th to the 19th. It is recommended that everyone adjust their clothing in a timely manner according to weather changes and appropriately "spring cover". In most parts of Xinjiang, Gansu, western Inner Mongolia, central northern Shaanxi, Shanxi, Beijing Tianjin Hebei, Liaoning, Shandong, Henan and other areas, there is a large temperature difference between day and night. In many places, the highest temperature during the day can reach about 10 ℃, but the lowest temperature is still below 5 ℃. The weather is warm and cold, and it is necessary to cover up in the morning and evening. Anhui, Jiangsu, Shanghai and other places feel damp and cold under the pressure of rainwater, so it is also necessary to cover up appropriately in spring to prevent catching a cold. The weather is cold in most parts of Qinghai, central and eastern Inner Mongolia, Heilongjiang, Jilin and other places. Among them, the highest temperature in Harbin on the 19th will only be around 1 ℃, and the lowest temperature will be below 9 ℃. Winter clothes such as down jackets and thick cotton jackets are still needed when going out. The temperature fluctuations in eastern Sichuan, Chongqing, Yunnan, Hubei, Jiangxi, Fujian, Guangdong, Guangxi, Hainan, Taiwan and other places are generally not significant, with some places reaching temperatures above 20 ℃. The feeling is warm and comfortable, and there is no need for "spring cover". Clothing can be flexibly adjusted according to one's own situation. Remember the principle of "815" for "spring covering". The degree of "spring covering" should be based on one's own feeling of warmth without sweating. If you don't feel dry throat and tongue when "covering", and your body doesn't sweat, even if the temperature is slightly higher, there is no need to rush to reduce clothing. If you feel sweaty after "covering" your body, you should change your clothes early, otherwise sweating from "covering" can easily lead to catching a cold from the wind. Spring warming "can follow the" 815 "principle: when the temperature difference between day and night is greater than 8 ℃, it indicates that the temperature is unstable and needs to be" warmed "; When the temperature remains above 15 ℃ continuously for one or two weeks, clothing can be appropriately reduced. For elderly people, patients with cardiovascular and respiratory diseases, "spring warming" can help the body adapt to temperature changes and reduce discomfort. However, not everyone is suitable for 'spring cover'! Children are naturally active and have a strong metabolism. "Spring holding" may lead to sweating and increase the risk of catching a cold. Learning the "onion dressing method" and "spring cover" is not about blindly wearing more clothes, but about reducing the impact of cold stimulation on the cardiovascular system through reasonable temperature regulation. The temperature fluctuates greatly, and the "onion dressing method" can be adopted to ensure sufficient warmth while also making it easy to put on and take off, avoiding catching a cold or sweating. Inner layer: clothes with good sweat wicking function; Middle layer: Clothes with strong warmth such as sweaters and sweaters; Outer layer: clothing made of waterproof, windproof and other materials. These three key "covering" and "covering" positions are also very important. Experts introduce that the scientific "spring cover" focuses on protecting the head, neck, abdomen, knees, and feet, following the principle of "thick at the bottom and thin at the top". Neck area: There are Fengchi acupoint and Fengfu acupoint in the neck area, which are places prone to wind evil. Protecting the neck can prevent wind and evil from invading. It is recommended to wear a scarf and hat according to the temperature. Abdominal area: mainly used to "cover" the navel, also known as the Shenque acupoint. Warming this area can stimulate the yang energy of the spleen and stomach, especially for those who are sensitive to cold and love diarrhea in the stomach, special attention should be paid to keeping the navel warm. Knee and Foot: As the saying goes, 'Cold starts at the feet', therefore, keeping warm for the knee and foot is particularly important. When it's cold in spring, it's important to wear shoes and socks with good warmth retention. The waist and joints are also prone to cold, so it is very important to keep warm. In terms of diet, it is also important to "spring cover". The purpose of "spring cover" is to protect the body's yang energy, so in addition to clothing, "spring cover" in diet is also very important. It is suitable to eat some spicy, warm and loose foods in spring, such as fermented black beans, chives, onions, cilantro, etc. Raw and cold foods should be consumed in moderation. In early spring, it is recommended to drink tea with mild properties, such as black tea and black tea, to avoid damaging the yang energy of the spleen and stomach. In addition to diet, soaking feet can also help replenish yang qi and regulate yin and yang. Soak your feet in warm water for 15-20 minutes before bedtime, which can help dilate the blood vessels in your feet, promote blood circulation, relax your body, and improve sleep quality.
