It usually falls on January 5-7 of the Gregorian calendar every year. between. The following are the climate characteristics of Xiaohan that I carefully recommend. They are for reference only. Welcome to read!

Xiaohan climate characteristics

According to the order, Xiaohan is the 23rd solar term among the 24 solar terms, and it is also a solar term in the twelfth lunar month to welcome spring. During the Lesser Cold, the sun moves to 285 degrees of ecliptic longitude, which is January 5 or 6 in the Gregorian calendar. Like the Great Cold, the Lesser Heat, the Great Heat, and the Extreme Heat, it is a solar term that expresses changes in temperature.

"Collection of the Seventy-Two Hours of the Moon Order": "In the December Festival, the cold at the beginning of the month is still small, so it is said. Half the moon is big." Xiaohan means that the weather is already very cold, and our country is cold. In some areas, the period of Minor Cold and Major Cold is generally the coldest period. As soon as the "Minor Cold" passes, it enters the third or ninth day of "going out on the ice". The characteristics of Xiaohan are: the weather is getting colder, but it is not yet very cold. The "March Nine" in the middle of winter is basically within this solar term, so there is a saying that "the minor cold is better than the major cold".

Two ancient folk proverbs, "Little Cold and Big Cold freeze together" and "Walking on the street, money is lost" both describe the coldness of this solar term. At the same time, this is around the time of the "March 9th", as the saying goes, "It's cold in the March 9th". This is because during the last winter solstice, the surface of the earth received the least sunlight and heat, but it was also supplemented by heat from the deep soil, so it was not the coldest time of the year.

After the winter solstice, around March 9th, the heat in the deep soil is also exhausted. Even though it gets a slight increase in sunlight and heat, it is still unable to make ends meet, so the lowest temperature of the year appears. During this solar term, most areas of our country have entered a period of severe cold. The soil is frozen, rivers are frozen, and the cold air from the north continues to move southward. The weather is cold, and people call it "Nine Cold Days." Although the southern part of our country is not as cold and cold as the northern part, the temperature has also dropped significantly. The coldest periods in the south are the two periods between Xiaohan and Rain and Jingzhe. It is dry and cold during the minor cold, and wet and cold after rain.

The importance of Xiaohan solar terms

1. Daily health care

"Huangdi Neijing" emphasizes that "no disturbance of Yang, go to bed early and get up late, must wait sunlight". In other words, in the cold winter, do not disrupt the body's physiological function of yin and yang conversion by disturbing the yang energy. In the cold season, you should get enough sleep, which is conducive to the hiding of yang energy and the accumulation of yin essence.

Wearing too few or too thin clothes and having a room temperature that is too low will make people easily catch colds and deplete their yang energy. On the contrary, if the clothes are too thick and the room temperature is too high, the colic will be released, the Yang energy will not be hidden, and the cold air will easily invade the body. When dressing, you should pay attention to the "clothing climate", which means that the temperature between the inner layer of clothing and the skin should always be maintained at 32°C to 33°C. This ideal "clothing climate" can buffer the human body from the invasion of cold weather outside.

2. Mental adjustment

In winter, people are easily affected by stoves, heaters, dry climate, etc. People are also very prone to "getting angry" and their moods are more likely to change. Traditional Chinese medicine believes that anger increases Qi and disturbs Yang Qi. Therefore, special attention should be paid to emotional regulation in winter. In winter, we must also prevent the occurrence of seasonal affective disorder. The so-called seasonal affective disorder means that some people are prone to depression, laziness, lethargy, drowsiness and other phenomena in winter, and they will appear year after year. .

This phenomenon generally occurs in young people, especially women. The preventive method is to bask in more sun and extend the exposure time, which is a natural therapy to regulate your mood.

What should you pay attention to during Xiaohan

Prevent frostbite

Xiaohan solar term is the coldest time period among the "Three Nines". Many readers are worried about frostbite at this time and come here on time. "check in". In particular, some girls are pretty and slender, but their hands are like slender carrots, red and swollen!

Folks often rub their hands with ginger, snow water, and ice cubes, and apply chili pepper water on their hands to prevent and treat chilblains, promote blood circulation in the hands, and accelerate blood circulation. Du Changming, director of the dermatology department of Nanjing Hospital of Integrated Traditional Chinese and Western Medicine, said that these methods can only prevent chilblains, but cannot treat them. If used improperly, it can also cause chilblains and may cause skin ulcers, leading to more serious conditions.

There is also the method of soaking in warm water to exercise the contraction and expansion functions of blood vessels, but it is only suitable before the formation of chilblains to reduce the chance of occurrence. It has no therapeutic effect on already formed chilblains and may even aggravate swelling. symptom.

Practice Sanjiu

The time should be late rather than early: During the Xiaohan solar term, it is best to wait until after sunrise for morning exercise, because the temperature rises after sunrise and the pollution in the air The amount of food has also been reduced, and there is also the function of sunbathing to avoid the cold.

The amount of exercise should be small rather than large: the amount of exercise should be gradually increased from small to large during each exercise, and do not engage in sudden strenuous exercise to avoid accidents. Be sure to make adequate preparations before exercising. Due to the low temperature in winter, slow blood flow and reduced elasticity and flexibility of muscles, joints and ligaments, sports injuries are easily caused.

The amount of exercise should not be large, but you can do Tai Chi, walking, gymnastics and other exercises.

Inhale through the nose rather than the mouth. Breathing through the nose and mouth should be used for exercise ventilation, because inhaling through the nasal cavity has a humidifying and warming effect on the air, and can also help protect the respiratory tract from dust and bacteria. In addition, winter exercise should choose exercise methods and locations based on the weather conditions of the day. Exercise in wind, heavy snow, heavy fog, and severe cold should be avoided. Exercise should be performed indoors during the above weather conditions.
