As the saying goes, "cold dew does not show your feet." After the cold dew, the temperature gradually dropped. Therefore, the public should not often be exposed shirtless to prevent cold air from invading the body. At the same time, summer sandals can basically be put away to prevent "cold from coming from the feet." Citizens can soak their feet with hot water every night, which can dilate blood vessels, speed up blood flow, improve skin and tissue nutrition of feet and feet, reduce lower limb pain and relieve fatigue.
According to the theory of keeping in good health, the foot is farthest from the human heart and bears the heaviest burden. Therefore, this place is most likely to lead to poor blood circulation, and the fat layer of the foot is very thin, with poor thermal insulation performance, which is easily stimulated by cold. It is found that there is a close nerve connection between foot and upper respiratory mucosa. Once the feet catch cold, it will cause the capillary contraction of the upper respiratory tract mucosa, and the ciliary movement will be weakened, which will lead to the decline of human resistance. Therefore, it is particularly important to keep your feet warm.
Step 2 add clothes at the right time
In addition, after the cold dew, the weather is cold, and the elderly, children and citizens with weak constitution should pay attention to cold and warmth, and gradually add clothes. As the saying goes, "Spring covers autumn", and moderate cold in autumn is beneficial to improve the cold resistance of skin and nasal mucosa, but the elderly and people with various chronic diseases should pay attention to cold and warmth to prevent "freezing" from getting sick. Don't change clothes too quickly when changing seasons. The thickness is best matched, mainly to keep warm. "Don't wear light clothes" is also an important point of cold dew health. Cold dew season, in daily life, should also be arranged reasonably. It is believed that when the temperature drops and the air is dry, the pathogenicity of cold virus increases. When the ambient temperature drops, the disease resistance of human upper respiratory tract will decrease. So in order to prevent colds in time, it is necessary to change clothes in time.
At the same time, first-aid drugs should be prepared at any time to prevent sudden diseases such as asthma, stroke and myocardial infarction caused by sudden drop in temperature.
3. The salt is late.
Cold dew is the beginning of autumn with alternating cold and summer. Autumn, autumn dryness is a troublesome thing. Health experts suggest that the best diet to deal with autumn dryness is "salt water in the morning and honey soup at night". It is found that the skin is getting drier and drier, and many people think that they can replenish water by drinking more water. The fact is that drinking boiled water alone is easy to lose water. However, if you add a little salt to the boiling water, the situation will be very different. This method is the same as supplementing normal saline.
4. Go to bed early and get up early
After the cold dew, the days are short and the nights are long, and the "yang" in nature begins to converge and precipitate. At this time, it is time for people to maintain yang, so people's living time should be adjusted accordingly. There is a saying in Su Wen's theory of regulating qi and spirit that "in autumn and March, people lie down early and get up early, having fun with chickens." The argument is to tell people the truth of keeping fit in autumn.
