Will it get cold or warm after the solstice in winter?

After the solstice in winter, the weather is getting colder and colder.

It has been a cold day in China since the winter of November. Astronomical experts say that the Ninth Five-Year Plan is a more applicable solar term in northern China, especially in the middle and lower reaches of the Yellow River. It started from the day when it met Ren in winter and entered the "number nine", commonly known as "cross nine". From then on, it was called "Nine" every nine days. After nine "nines", it's just 8 1 day, and then spring blossoms.

In ancient times, especially in northern China, the conditions for working people to keep warm from the cold were simpler than their descendants. Winter is regarded as a threat and punishment, which directly affects people's mood and even makes them feel that winter is inexplicably long. At that time, in order to survive the long winter, the people of China invented the method of "counting nine" to pass the time, so as to alleviate the psychological crisis under the threat of winter.

Extended data:

Nine cold days, biting north wind, is the season of frequent diseases. At this time, if you can eat more cold-resistant foods that help improve immunity, it will be beneficial to prevent some diseases. Foods that help strengthen the body's ability to resist cold and prevent diseases are:

1, meat, eggs, milk

According to the daily intake of protein recommended by nutritionists 1.0 ~ 1.2g/kg body weight, the winter should be dominated by high-quality protein, including milk, eggs, meat, beans and their products. High-quality protein contains a lot of essential amino acids, which is an important part of nucleoprotein, hormone, enzyme and antibody, and also an important source of maintaining "heat".

2. Mutton

In particular, mutton is sweet and hot, which has the effects of invigorating qi and tonifying deficiency, warming the middle and lowering the temperature, and is also beneficial to prevent lung infection, bronchitis, asthma, anemia, soreness of waist and knees and various deficiency-cold syndromes.

3. Pepper

Pepper is rich in carotene, protein, fat, vitamin C, calcium, phosphorus, iron and other nutrients. Studies have found that capsaicin contained in pepper can increase gastric acid secretion, enhance appetite, and also make people's heart beat faster, open pores, expand skin capillaries, and accelerate blood flow, which can play a "warm body" role.

4. Jujube

Jujube contains protein, sugars, organic acids, vitamins and trace elements. Eating red dates regularly can prevent qi and blood deficiency, malnutrition, spleen and stomach weakness, protect the liver, and enhance muscle strength and immunity.
