According to modern scientific research, the body temperature is basically constant at around 37 ℃, and the body can adjust the body temperature by itself, such as sweating and central regulation. When the ambient temperature is higher than the normal temperature of the human body, we will feel heat. When the ambient temperature is lower than the normal temperature of the human body, we will feel cold. Our brain will instinctively direct us to control the stability of the body's temperature by increasing or decreasing clothes.
Then why do you have to "cover up in spring"? After our body protects warm clothing in winter, the body's own adjustment mechanism has adapted to the current balance. If you take off your winter clothes too early and expose yourself to a slightly warm but unstable temperature, the temperature regulation mechanism will not be able to establish a new balance, which is particularly prone to cause the body's cold and cold imbalance, the body's immunity and resistance to decrease, and then be attacked by the disease. Similarly, "Autumn Frost" is the same principle.
In addition, "cover spring and freeze in autumn" is a traditional way of health preservation. Because the temperature in spring increases and decreases, it is necessary to add or reduce clothes to balance the temperature of the human body to avoid being troubled by miscellaneous diseases.
Winter is gone and spring is coming, it is warm and cold, and the temperature changes greatly. If you take off your cotton coat too early, once the temperature drops, it will be difficult to adapt and reduce your body's resistance. After wearing cotton coats for several months in winter, the body's heat production and heat dissipation adjustment is in a relatively balanced state with the ambient temperature in winter. At this time, the bacteria invade the body, which can easily cause various respiratory diseases, leading to colds, bronchitis, , arthritis and other diseases.
Generally speaking, 15 degrees Celsius is a critical value. When it is below this temperature, it is best to continue to "tolerate" the inconvenience caused by heavy clothing; when it exceeds this temperature, you can consider taking off some clothes.
Secondly, based on your feelings: everyone has different physiques and different tolerance to hot and cold. If you don't feel hot and sweaty when you "cover", you don't have to rush to take off your clothes even if the temperature is slightly above 15 degrees Celsius. If you feel that "covering" your body will make you sweat, you might as well change your clothes as soon as possible. Otherwise, you will sweat while "covering" your body, and then you will catch a cold when blown by the cold wind.
In addition, the climate changes greatly in early spring. Even if the temperature is warmer than in winter, most of the yang energy in the human body fails to grow and radiate in time. The temperature drops sharply, and people with weak resistance are prone to colds. Therefore, in early spring, pay more attention to keeping warm and do not take off your winter clothes too early. Especially before the Qingming Festival, we should pay attention to weather forecasts in a timely manner. After the Qingming Festival, with the arrival of spring rain, the temperature will gradually rise steadily. At this time, according to the weather changes, you can reduce clothes in a timely manner.
Modern medicine believes that the blood circulation in the lower part of the human body is worse than that in the upper part and is prone to cold. Therefore, "Spring Cover" should focus on keeping warm wrists, waist, navel, calves and feet. Thick pants and thick socks should not be reduced too early, and your feet should be soaked in hot water. The lower cover should be thicker when sleeping.
Summary
We should adhere to scientific concepts in inheriting common language culture. In daily life, we often hear various folk sayings. These proverbs may be related to our production and life, or they may teach people how to be a human being and tell the truth of life. In short, the birth of every proverb has its social background and its value at that time, but it is precisely because of different historical periods and different events that many statements are not correct. We should analyze and understand dialectically based on science.
