Why is the temperature difference between day and night big in autumn? These three places must not b

Recently, do you feel that autumn is coming? It's very comfortable, but it's very cold at night. What's the matter? The big temperature difference between day and night in autumn is mainly related to the frequent search of cold air activities in autumn and the excessive radiation cooling.

In autumn, the force of the north wind gradually strengthened, and cold air activities were more frequent. At the same time, in autumn, there are less clouds, faster flow of cold air and faster cooling. After autumn, with the southward movement of the direct sunlight point, the daytime time is shortened, and the sunshine hours are reduced day by day. With the decrease of solar radiation, the heat gained by the ground in the daytime gradually decreases. However, with the extension of night, the heat radiated from the earth's surface increases. Because the heat absorbed by the ground is less than the heat lost from the ground, the temperature tends to change from high to low.

We all know the saying of "spring covers autumn frost". However, it is relative and conditional that 'spring covers autumn frost'. For young people and strong people, when adding clothes, they can be later and stronger. For old people and weak people, especially the old people with unhealthy cardiovascular and cerebrovascular functions, they should pay attention to discretion and even cover spring covers autumn.

There are three places where autumn frost can never be frozen!

Unfrozen head

Prevention of headache, cerebral infarction and cold

Compared with the humid wind in summer, the autumn wind is dry and fierce, so when you sweat in autumn, you can't blow dry like in summer, especially when you sweat on your forehead.

Traditional Chinese medicine believes that the head, as the body's "meeting of all Yang", is one of the most vigorous parts of the body Yang. The autumn wind is low in temperature and humidity, which brings a lot of Yang Qi away from the forehead and makes cold evil invade. This can lead to vasospasm of the head, causing colds, migraines, blood clots falling off, and even cerebral infarction.

Warm recommendations

✦ after autumn, wash your hair with water hotter than usual, not to mention cold water.

✦ when sweating in autumn, it can't be dried naturally, especially when the forehead is sweating, it can't see the wind.

✦: when going out in the morning and evening, and the wind is strong, you can take a hat to prevent the head from being winded.

&#People with cardiovascular and cerebrovascular diseases, people with vascular diseases of extremities, people with hypothermia of extremities and people susceptible to wind chill should be especially vigilant in this regard.

Unfrozen stomach

Prevent abdominal pain, diarrhea and dyspepsia

The second characteristic of autumn is the large temperature difference between morning and evening, more than 10 degrees in the morning and evening, and the chilly wind, 2 or 30 degrees in the noon, and the hot sunshine. If you don't add clothes in time, one of the most easy places for your body to catch cold is your waist and abdomen.

The navel is called Shenque point in traditional Chinese medicine. Warming this point can stimulate the body's Yang, especially for those who are weak in spleen and stomach, afraid of cold and easy to diarrhea. They should pay special attention to the warmth of this part. They can also take the method of frequent hot compress on the navel to expel cold and help Yang.

In autumn, many gastrointestinal diseases are related to the cold of navel. There is no fat under the navel, close to the rich nerve endings and plexus, especially sensitive to external stimulation. Once the navel catches cold, children's autumn diarrhea, middle-aged enteritis, middle-aged and old people's dyspepsia, etc. are all found.

Warm recommendations

&#Do not expose your navel and waist when you wear clothes. If the clothes are short, you can wear high waist pants or high waist skirt.

✦ if you need to leave early or return late, take a light cardigan with you, and wear it sooner or later.

✦: it's still very hot in the south. When you go to bed at night, you need to cover your stomach with a towel and pajamas.

✦: if you have already got cold, you can moxibustion Shenque acupoint if you have moxa stick at home, or you can use hot water bag to heat up if you don't have moxa stick, and then drink ginger and sugar water.

Unfrozen foot

Invasion of cold proof pathogen and recurrence of old diseases

Spring cover autumn freeze, although autumn freeze is good, but the most can not be frozen is feet. By this time in autumn, the temperature difference between morning and evening is getting larger and larger, and the foot is farthest from the heart. If you still wear sandals, it's strange that your feet will not be frozen.

According to traditional Chinese medicine, feet are the root of human beings. Six of the 12 meridians of the human body start from the feet. These meridians move Qi and blood, communicate the exterior and interior, connect the viscera and pass through the upper and lower channels of the human body. In addition, there are also "cold comes from the bottom" and "people grow old before their feet". So feet get cold, which means the whole body gets cold.
