First, when will the "spring cover" be "covered" and when will it be covered?
At the beginning of February every year, that is, at the beginning of spring, we can gradually feel the temperature rising, and even the wind blowing on our faces feels much softer. Especially in March, the temperature changes quickly and clothes change quickly. Many people took off their heavy winter clothes and put on thin spring clothes, and even put on short sleeves.
In spring, the temperature of nature is on the rise, but the temperature changes greatly. If you don't pay attention to the weather changes, you will probably catch a cold if you take off your clothes in advance.
The peak of many diseases is closely related to the duration of cold air going south and cooling down, the most obvious ones are colds and indigestion. It is necessary to "warm up" before the arrival of cold air, so the best time for "spring cover" is to keep warm 24 to 48 hours before the arrival of cold air predicted by the Meteorological Observatory and add clothes in time. In addition, the temperature difference between day and night is greater than 8℃, which is also a signal of rain.
"Spring covering" pays attention to the duration, and generally 7- 14 days is just right. Experts believe that as the temperature rises, the clothes that "cover" the body will always take off part. But the clothes should not be cut too fast, otherwise the clothes cover will not be in place.
So how do you cover it in place? Medical scientists have found that it is necessary to add clothes to keep out the cold when the temperature returns to cold. Even if the temperature rises later, it will take about 7 days for weak children and the elderly to adapt. If you cut clothes too fast, you may freeze to death.
We talked about the time and duration of "spring covering", so when should we stop covering? In fact, when the temperature is kept above 15℃ and relatively stable, the "covering" can be stopped.
Second, how to cover the "spring cover" and where is the cover?
When it comes to covering, many people will think that since it is covering, it means wearing more clothes. In fact, this is not entirely correct. The blood circulation in the lower half of the human body is worse than that in the upper half, so it is easy to catch cold, so cold is mostly born from the bottom. Therefore, dressing in spring should pay attention to "coarse and fine".
So pay more attention to the lower parts of the body, especially the legs and ankles. Many young fashionable people forget to wear less clothes. The key is that their ankles are still exposed in the cold weather, which makes people feel cold.
Therefore, if you don't pay attention to keeping warm in spring, you will cut down your clothes as soon as it gets hot. If you don't pay attention, you will catch a cold and have a fever. Even when you are old, your knee joint hurts and gradually develops into knee joint hyperosteogeny. In severe cases, there will be hydrops, swelling and inability to straighten the knee joint.
"Spring covers the autumn and it freezes" is an old proverb of China. Up to now, we still have a saying that "if you don't listen to the old man, you will suffer in front of you", so we still have to listen to the experience of the ancients.
