About the knowledge of slight cold, slight cold is the end of February and the beginning of ugly month. The time is between 65438 and1October 5-7 every year, which is the coldest day among the 24 solar terms and marks the beginning of the coldest day of the year. Let's take a look at the knowledge about slight cold.

Slight cold knowledge 1 slight cold is the 23rd solar term in 24 solar terms and the 5th solar term in winter.

According to the astronomical calendar of China, the "slight cold" solar term was ushered in at 5: 30 on June 6, 65438, marking the official start of the winter season.

At this time, it is the coldest "March 9" period of the year, "it is difficult to relax when dripping into ice", but the flavor of the year is getting stronger and stronger. People began to enter the rhythm of "busy year" and began to make various preparations for the Spring Festival.

Fighting fingers; The meridian of the sun is 285; Gregorian calendar 65438+1October 5-7. The slight cold marks the official start of the season and winter. Cold air is cold for a long time, and slight cold means that the weather is cold but not extreme.

Which is colder, slight cold or severe cold?

Statistics of historical data show that the situation is different in different places and different years. Generally speaking, the average minimum temperature of severe cold solar terms in the north is lower than that of slight cold solar terms. The south is the opposite.

During the slight cold season, most parts of China have entered a severe cold period, with frozen soil and rivers frozen. In addition, the cold air in the north continues to go south and the weather is cold. People call it "counting nine cold days" Although it is not as cold in the south of our country as in the north, the temperature has dropped obviously. The coldest time in the south is slight cold, between rain and fright. It is dry and cold when it is a little cold, and it is wet and cold after the rain.

Characteristics of slight cold

When the sun meridian reaches 285 degrees, the slight cold solar term begins. Cold means cold, and slight cold means the degree of cold.

In the south of China, winter is very warm. The middle of winter is 1 month, with frost and snow attacking and often freezing. The lowest temperature is about-10℃. The lowest temperature in northern South China is rarely below MINUS 5℃, and the low temperature below 0℃ in southern South China is even rarer. The coldest area in the middle of winter in China is the northern part of Heilongjiang, and the lowest temperature can reach about MINUS 40℃. It's freezing, dripping into ice.

The low-altitude valley is the warmest place in the middle of winter in most parts of southern China. The average temperature in 65438+ 10 is around 12℃, and only a few teenagers may have a low temperature below 0℃. In addition, the inversion effect is very significant, so tropical fruits such as bananas and mangoes can grow well.

As the saying goes, "March 9th is cold". "Sanjiu" is mostly from 65438+1October 9 to 17, which is also within the slight cold solar terms. But this is just a general rule. In a few years, a bad cold may be colder than a mild one.

The lowest temperature in winter in the south is not low, which is beneficial to production and is also suitable for developing diversified businesses. Citrus "was born in the south" generally requires a minimum temperature of not less than minus 5℃ and an annual temperature higher than 15℃, which can be met in most parts of South China and almost all subtropical plants. Only in this way, the unique climatic conditions should be a very important factor.

Slight cold has "third class"

The ancients used phenological representations of flowers, birds, grasses and insects to annotate each solar term, and each climate had a response, that is, the most representative phenology was extracted as the phenological response of this climate. Then the climate of each climate is integrated to form 72 climates with 24 solar terms.

Among the 24 solar terms, only the white dew and slight cold are completely recognized by birds. The ancients thought that "birds are not on fire", and birds have unparalleled talent in sensing the flow of yin and yang.

The story of Han Xiao described by the ancients is: waiting for Yanbei Township, waiting for magpies to build nests, waiting for pheasants to build nests. Wild geese move northward, magpies build nests, and pheasants sing.

Yanbei Township (Xiang). The meaning of hometown and guide. When the sun goes down, the geese will avoid the heat and return. Today, they will fly to the north of the country, and they will all return to the beginning of spring, so the birds will be angry first.

Magpies began to build nests. Magpie, the door of the magpie's nest is too old. From the winter solstice to Tianyuan and the next year's solar term, magpies can live in a nest and know what to do.

It's only a matter of time. Pheasant, a civilized bird, is also a sunny bird; "Pheasant" means singing. Near April 9, pheasants can sing.

Knowledge of slight cold II. Slight cold tonic is because people eat.

Speaking of tonic, there has been a saying since ancient times that "three nine make up one winter, and there will be no disease in the coming year". After eating in spring, summer and autumn, the yin, yang, qi and blood of zang-fu organs will decrease to some extent. Reasonable tonic can not only replenish qi, blood and body fluid in time to resist the cold, but also make young people suffer from less diseases in the future and achieve the goal of getting twice the result with half the effort. Tonifying in winter, combining food tonic with medicine tonic, and warming tonic is appropriate.

Sun Simiao, a famous doctor in the Tang Dynasty, pointed out: "The foundation of peace of mind must be based on food ... those who don't know how to eat correctly are not enough to survive ... so food can dispel evil spirits and stabilize viscera." This shows the effect of diet on human body. Although the light snow solar term has been cold for several days, it is understandable that people make up for it, but it is essential to make up for it. We should understand the meaning of dietary taboos according to the principle of "different from person to person". The dietary instructions of the Yuan Dynasty emphasized: "Diet is for health, but I don't know whether the physical properties are suitable for each other. Even if they are mixed together, it will lead to internal discord and cause great disaster. " Therefore, young people should not be hurt by the "five flavors" when taking supplements, but should selectively take supplements according to their own situation.

Fat, sweet and delicious, eating too much will hurt your health.

Generally speaking, young people have a vigorous metabolism and need more protein and calories than the elderly, and calories mainly come from carbohydrates and fats. Carbohydrate mainly comes from cereals, so young people should ensure adequate appetite, pay attention to the proportion of coarse grains in flour and rice and take in appropriate amount of fat, which are all considerations when choosing medicinal diet for tonic. But young people have the characteristics of young people. There are often people who eat greasy and spicy products and attract uninvited guests-"acne", which brings endless troubles to young people.

Warming is the best way to keep warm.

Traditional Chinese medicine believes that cold is yin evil, and the coldest solar term is also the most prosperous period of yin evil. From the point of view of diet health, we should pay special attention to eating more warm food in our daily diet to supplement our health and prevent the invasion of cold climate. Commonly used tonics include Ginseng, Astragalus, Colla Corii Asini, Cordyceps sinensis, Polygonum Multiflori Radix, Lycium barbarum and Angelica sinensis. Dietary supplement should choose mutton, dog meat, pork, chicken, duck, eel, soft-shelled turtle, Spanish mackerel, sea shrimp and other foods such as walnut kernel, jujube, longan, sesame, yam, lotus seed, lily and chestnut according to the ups and downs of yin and yang. All the above foods have the effects of nourishing spleen and stomach, warming kidney and strengthening yang, strengthening spleen and resolving phlegm, relieving cough and tonifying lung. Of course, people who are too hot, too solid and easy to get angry should pay attention to slow tonic and eat less.

Winter exercise varies from person to person.

The slight cold solar term is the coldest time of the year in the "March 9" cold weather. This is a good opportunity for people to strengthen physical exercise and improve their physical fitness. However, according to one's physical condition, one must not be blind. Even strong people should pay attention to the ways and methods of exercise. You can take part in 2 ~ 3 fitness exercises every week, such as swimming, playing tennis and bowling. In our daily life, we should often walk, jog and exercise. In addition, we should pay attention to indoor ventilation and keep warm when going out to prevent respiratory diseases. In a word, the slight cold regimen should vary from person to person, and people should eat food to make up for it.

Foot massage

Life lies in exercise. The folk proverb also says, "if you move in winter, you will get less sick;" Lazy in winter, drink a bowl of medicine. "This shows the importance of winter exercise. People who are good at keeping in good health should insist on physical exercise in winter to achieve the effects of nourishing liver and kidney, relaxing tendons and activating collaterals, dredging qi pulse and enhancing their own resistance. For example, yoga, Tai Ji Chuan, walking, jogging, skipping rope, kicking shuttlecock, playing ball, doing exercises, practicing boxing and sword, etc. Are suitable for winter exercise. Keep warm during winter exercise to prevent colds. Psychologically, be calm, worry less, be optimistic, don't worry about trifles, be calm and add fun.

Knocking your teeth often in winter will benefit your kidney and strengthen your kidney; The meridians of the kidney start from the foot, and Yongquan point in the heart of the foot is its main point. It is best to soak your feet with hot water before going to bed in winter night and press the center of your feet; In winter, people are in a state of "Yin flourishes while Yang declines", so they should bask in the sun to help Yang Qi in the kidney rise; Pay attention to keep your back warm and wear cotton or wool vest to protect kidney yang.

During the winter solstice, the ground gets the least solar heat, but some heat in the deep soil can still be emitted upwards, so it is not the coldest time all year round. In the slight cold, the heat in the deep soil is lost to the lowest point. Although the days are a little longer and the sun's light and heat are slightly increased, it is actually the most difficult time to make a living, so it becomes the coldest season all year round.

China's traditional culture emphasizes "extremes meet" and thinks that the "day" of alternating cold and summer is to recover quickly after a cold. If you caught a bad cold before the slight cold, you can't just feel "recovered" after the coldest. Therefore, it is in line with the thinking habit of China people to put the severe cold behind them and let them return to beginning of spring quickly after the severe cold.

What traditional food does Xiao Han eat?

1, eat mutton

According to folklore, "Xiao Han eats mutton and Da Han eats radish". Slight cold is the coldest time of the year, and mutton is also a very popular traditional food in the slight cold solar terms. Mutton is the most cost-effective warm food, which can not only keep out the cold, but also benefit the body. If you add some angelica, yam and carrot to mutton and cook it together, it won't get angry and you can spend a warm winter.

Step 2 eat laba porridge

Because the time of Laba Festival is between mild cold and severe cold, many places have the custom of eating Laba porridge on this mild cold day. There are many ingredients in Laba porridge, including yellow rice, Redmi, white rice, millet, water chestnut rice, chestnuts, red beans and jujube paste. Cook with peach kernel, almond, melon seeds, peanuts, pine nuts, brown sugar, white sugar and raisins.

Step 3 eat soybean sprouts

During the slight cold, old Nanjing usually cooks meals with different contents. Cook short-legged yellow vegetables with sliced bacon, sausage or diced salted duck, and chop some ginger with glutinous rice. It's delicious. Among them, dwarf yellow, sausage and dried salted duck are all famous specialties in Nanjing, which can be described as "Nanjing vegetable rice" and even comparable to Laba porridge.

Step 4 eat glutinous rice

As the saying goes, "slight cold and severe cold have no wind and cold", and it is popular in Guangdong to eat glutinous rice to drive away the cold. Besides glutinous rice, bacon, sausage and peanuts, traditional preserved meat also includes mushrooms, dried shrimps, scallops, coriander, barbecued pork and squid. Generally, Xiao Han and Da Han eat glutinous rice in the morning, but because they have no time to go to school and work, they eat it at night instead.

Step 5 eat vegetable rice

In ancient times, Nanjing people paid special attention to slight cold, but with the passage of time, it has gradually faded now. However, the custom of eating vegetable rice in the slight cold season is still very popular. In poor families or difficult times, vegetable rice is rice cooked with vegetables and salt. If conditions are good, it will be served with bacon, sausage, ham, diced salted duck, chopped with some ginger and cooked with glutinous rice. It is very delicious.

6. Warm chicken soup

Old Nanjing also has the habit of eating a chicken and an egg every September, so on this chilly day, chicken soup and eggs are indispensable on the table of the citizens. The medicinal value of chicken is great, and the people have the reputation of "the medicine to save the world". Chinese medicine believes that chicken has the effects of warming the middle warmer, benefiting qi and filling the marrow.

However, it is necessary to pay attention to the difference between men and women when using chicken for tonic: the rooster belongs to yang and has a strong warming and tonic effect, which is more suitable for patients with yang deficiency and weak qi; Hens belong to yin, which is more suitable for lying-in women, the elderly, the sick and the disabled.
