Spring cover properly to protect health
Spring is the transition season from winter cold to summer heat, it is in the Yin retreat Yang long, cold to heat to the transition period. At this time, the yang is gradually born, and the cold is not yet finished, because the cold air is still active, the climate is variable, the temperature difference is very large. Therefore, in some areas, the weather can change drastically within a day. Sometimes the sun rises in the morning, the spring breeze sends warmth, and the sun shines at noon, and the temperature rises suddenly, but in the evening it may be a sudden cold stream, cold air forced. Therefore, if you dress thinly in early spring, it is easy to feel the spring cold and get sick. Zhang Lingyan, Medical Examination Department, Chongqing Bishan District People’s Hospital
Historically, ancient doctors have stressed the common saying of “spring cover”, that is, “spring is not busy to reduce clothing”, the folk saying “in February to put cotton clothes skim, March or pear snow”. “eat the Dragon Boat Festival zong, and then send the cold clothes”, these say is also this reason.
The traditional medicine of the motherland believes that “spring cover” is not only in response to the Yang Qi growth of health needs, but also to prevent disease self-care prescription. Sun Simiao, the king of medicine, said: “Spring is not thin clothing, people have typhoid, cholera, food, headache.” Ming Dynasty physician Wang Qishi said, “Spring wind, and cold.” Modern people have also long recognized that, such as premature removal of cotton clothing, very vulnerable to cold, cold is injury to the lungs, prone to influenza, acute bronchitis, pneumonia and other diseases. Spring is also the season for influenza, measles, mumps and other infectious diseases. The occurrence of these diseases is related to bacterial and viral infections, but the onset of the infection is largely determined by the individual’s physical condition and living regimen. If you are not too busy to take off your clothes, “spring cover” properly, will reduce the chance of disease.
How to properly “spring cover”? The ancient medical text “regimen news theory” pointed out: “spring weather cold and warm, not to go to the cotton clothes, the elderly weak bones sparse body timid, wind and cold easy to hurt the coup, when the jacket, warm and easy, a heavy reduction of a heavy, not a storm to go.” This means that cotton clothes should not be taken off too early, more than a few pieces of jacket, with the weather changes increase or decrease. But sometimes the spring cover is should be degree, when the southern region into March, or the northern region into April, the weather is obviously some hot, then if still wearing cotton clothes, will exceed the body’s heat-resistant limit, the body temperature regulation center will not adapt, the same is not good for health. Especially in the Yangtze River basin, spring air humidity, if the “cover” over the head, but also easy to induce heat stroke.
With the rise of medical meteorology, scientists have a lot more scientific and specific research on spring cover, put forward some data for people to facilitate the “operation” in practice, let’s call it the spring cover index.
One, grasp the timing: 24 to 48 hours before the arrival of cold air for a rainy day.
Medical meteorologists have found that the peak incidence of many diseases is closely related to the time when the cold air comes south and the cooling lasts. For example, colds, indigestion, long before the arrival of cold air will be shortcut. And glaucoma, myocardial infarction and stroke also increase suddenly when cold air crosses the border. Therefore, the best time to cover, should be 24 to 48 hours before the arrival of cold air forecast by the weather station, and then late is the umbrella after the rain.
Second, grasp the temperature: 15 ℃ is the critical temperature of the spring cover.
Research shows that for most older people or frail and sickly people who need spring cover, 15 ℃ can be considered the critical temperature of cover and not cover. In other words, when the temperature continues to be above 15 ℃ and relatively stable, you can not cover.
Third, pay attention to the temperature difference: the temperature difference between day and night is greater than 8 ℃ is to cover the signal.
Spring temperatures, the day before or spring breeze and warm, spring flowers, the moment may be cold, “flowers and blown down by the wind”, so you look back on the winter slaughter. The face of the “child’s face” like spring, you have to add or remove clothes with the weather changes. And when to add clothes? Now it is believed that the difference between day and night temperature greater than 8 ℃ is the signal to cover.
Fourth, the duration: 7 to 14 days is just right.
Covered clothing, as the temperature rises always have to reduce down. And reduce too fast, there may be “always single shirt resistant to freezing, the first off the cotton clothes freezing into disease”. Because you did not cover the right place. How to be considered in place? Medical doctors found that the temperature back to cold need to add clothes to protect the cold, even after the temperature has risen, but also have to cover about 7 days, weak or elderly people have to cover more than 14 days to adapt to the body. Reduce too quickly may freeze out of disease.
