Is it meaningful to cover spring and freeze autumn? why

It makes sense to cover the spring and freeze the autumn.

Spring cover:

In spring, the temperature of nature is rising, but the indoor temperature can't keep up with the outdoor because of the thermal inertia of the house, resulting in the temperature difference between indoor and outdoor. This temperature difference reaches its maximum in the sunny afternoon of a day, often as high as 3-5℃ or even more.

Especially when walking into a cool room from the warm sunshine, the elderly and patients must put on clothes and spring clothes to avoid catching cold and getting sick. Because the temperature rises (falls) fastest in spring (autumn) in China at the same latitude, the unique health-keeping proverb "Cover the spring and freeze the autumn" in China was born.

Winter goes and spring comes, which is a transitional stage from cold to hot. Although the weather is getting warmer, the climate often changes, sometimes warm and sometimes cold. Often after the sun comes out, it will be warm and sunny, and it will be cold when it is windy and rainy.

Because people are used to wearing more clothes in winter, if they take off too much in spring, they will not adapt to climate change and get sick easily. Therefore, in the early spring, you should deliberately cover a little and slowly reduce your clothes.

Autumn freezing:

When the temperature drops in autumn, the indoor temperature lags behind the outdoor nature due to the thermal inertia of the house, resulting in an opposite temperature difference. Walking into the room from the outside, the temperature rises, so it is natural to take off your clothes and freeze in autumn to prevent sweating from hurting your body.

Going to Qiu Lai in summer is a transitional stage from hot to cold. Although the weather is getting cold, there is a process of transformation.

Some people wear a lot of clothes in autumn, and even put on cotton-padded clothes too early. This is not good, because putting on cotton-padded clothes too early will make the body unable to exercise in cold air, reduce the cold-proof ability, and is not conducive to the adjustment of human functions;

In this way, in the cold season of March 9, once the nose and trachea are attacked by cold air, the blood vessels inside can't resist and contract, reducing blood flow and weakening antibacterial ability. Bacteria hidden in the nose or trachea take the opportunity to move, causing cough, sneezing, runny nose, fever and cold. Therefore, it should be frozen again in autumn, and clothes should be added slowly.

Frozen taboo crowd in autumn

First, patients with cardiovascular and cerebrovascular diseases

The temperature changes greatly in late autumn, and the temperature difference, wind speed and air pressure are in a state of great fluctuation. This changeable weather will make the blood vessels of human skin and subcutaneous tissue contract and the resistance of peripheral blood vessels increase, which will lead to the increase of blood pressure and blood viscosity. In severe cases, it can also lead to angina pectoris and myocardial infarction. In patients with coronary heart disease, they may even have a stroke due to brittle fracture of blood vessels, which will cause hemiplegia and endanger their lives.

Therefore, all elderly people with cardiovascular and cerebrovascular diseases should not be frozen in late autumn. On the contrary, they should pay attention to keep warm and add clothes in time as the weather changes, so as to avoid the recurrence of old diseases affecting their health.

Second, patients with asthma and bronchitis

For some elderly people with chronic bronchitis, their airway defense function is poor, and their body resistance is greatly reduced when they catch a cold. After being invaded by germs and viruses, it is easy to cause colds, coughs, tonsillitis and pneumonia. Asthma patients are extremely sensitive to seasonal temperature and humidity changes, and weak resistance can easily cause upper respiratory tract infection and induce asthma.

In addition, the large increase of allergic substances in food and air is also an important reason for the susceptibility of the disease. "The most important thing for patients with asthma and bronchitis is that they can't catch a cold, so it is very important for them to keep warm and change clothes in time." Patients with asthma and bronchitis must pay attention to preventing colds.

Third, patients with stomach problems.

Gastrointestinal tract is very sensitive to cold stimulation. Due to the changeable temperature in late autumn, especially the sudden attack of cold air on gastrointestinal tract, if it is not properly protected, the old disease will recur. Moreover, some people eat cold drinks in late autumn, and some people like spicy food such as peppers. These eating habits are very likely to cause stomach problems, so pay special attention.

Fourth, patients with old cold legs

Patients with old cold legs will aggravate their symptoms when they are cold. Old cold legs belong to the category of arthralgia syndrome in traditional Chinese medicine, which is equivalent to osteoarthritis such as rheumatoid arthritis and osteoarthritis in modern medicine. Knee joint is the main joint involved, and joint pain often occurs, sometimes accompanied by swelling, and the pain is aggravated when going upstairs or downstairs. Old people with cold legs should pay attention to keeping their legs warm from autumn.

Five, female body cold patients.

For some female friends who are afraid of the cold, especially those with cold hands and feet and cold abdomen in winter, we must pay attention to keeping the ankles, abdomen and waist warm in autumn, so as not to aggravate the body cold and even cause diseases such as palace cold and irregular menstruation.
