Will the temperature be cold after the vernal equinox? What should I pay attention to?

The vernal equinox indicates that the weather is getting warmer and the temperature is rising. But the weather is changeable, and sometimes there will be cold in the spring.

The average daily temperature in different places is generally below 10 ~ 12℃ (the standards vary from place to place), which may cause serious rice seedling rot for more than 5-7 days. Because rice and cotton are both thermophilic crops, when the temperature is above 10 ~ 12 and the minimum temperature in sunny days is above 5℃, it is beneficial to all seedlings.

Conversely, if there is low temperature and rainy weather, you can imagine. First frost is the product of cold wave and strong cold air in spring. In the case of warmer climate, cold waves are relatively rare, but we should not be careless.

Need to pay attention after the vernal equinox:

Early spring has come, and the temperature has risen, but it is still warm and cold, and the climate is changeable. This rise is a gradual process. The temperature rises and falls, and people often can't predict this change. When the temperature rises, they will add clothes, but the temperature suddenly drops and the clothes have not been added. This is easy to suppress the yang, hinder the drainage of the liver, and affect health.

It is also prone to colds, bronchitis and other diseases. Therefore, it is necessary to adapt to the moderate climate and follow the principle of "thin on the top and thick on the bottom". The human yang is rooted in the kidney. In spring, with the recovery of yang, the yang in the kidney will gradually grow, while the kidney will live at the waist, and the yang will spread to the whole body from now on. Once the wind and cold attack, the yang will be trapped in the sun, hindering the blood circulation below the waist, causing symptoms such as weakness of the waist and knees, pain and numbness.

Therefore, in early spring, don't change clothes too quickly and don't take them off too early. Remember the dressing principle of "the upper part is thin and the lower part is thick", that is, the pants, socks and shoes of the lower part must be thicker and warmer, and a slight reduction in the upper part will not be a big obstacle.

It is advisable to eat less sour food and more sweets in spring. Chinese medicine believes that when the liver qi is strong in spring, eating more sour food will make the liver qi excessive and damage the spleen and stomach, so eat less sour food. After entering the spring, people have more outdoor activities than in winter, and their physical energy consumption is greater, and the required calories are increased.

But at this time, the spleen and stomach are weak, and the digestive ability of gastrointestinal tract is poor, so the required heat can be properly supplied by sweets. Namely: red dates and honey are the first choice in the spring equinox season. Chinese medicine believes that red dates and honey are sweet, and when they enter the spleen and stomach, they can replenish the middle energizer and relieve constipation.

Because red dates and honey contain a variety of minerals and vitamins, they can benefit qi and detoxify and enhance human immunity, so they are the most ideal tonics in spring. Therefore, in spring, if you eat a few red dates or drink 1-2 spoonfuls of honey every day (with 1 cup of warm water or milk), it will have a nourishing effect on your body.

First, the vernal equinox introduction:

The vernal equinox is the midpoint of 90 days in spring. One of the 24 solar terms, around March 20 of the Gregorian calendar every year, when the sun is located at 0 (vernal equinox) of the yellow meridian. On the vernal equinox, the sun shines directly at the equator of the earth, and the seasons in the northern and southern hemispheres are opposite. The northern hemisphere is the vernal equinox and the southern hemisphere is the autumnal equinox. The vernal equinox is a new year in Iran, Turkey, Afghanistan, Uzbekistan and other countries, with a history of 3,000 years.

Twenty-four solar terms: "in mid-February, half a minute, that is, half of 90 days, so it is called minutes." Autumn is synonymous. " "Spring and Autumn Stories Yin and Yang in and out" said: "The vernal equinox, Yin and Yang are also half-phase, so it is cold and summer day and night."

The vernal equinox is also a festival and ritual celebration. The ancient emperors had a system of offering sacrifices to the sun in spring and the moon in autumn. The ritual of the Zhou Dynasty was to offer sacrifices on the altar.

Book of Rites: "Altar." Ying Da Shu by Confucius: "Also called vernal equinox". In the Qing Dynasty, Pan Rongbi wrote "Ji Sheng at the age of Emperor Jingdi": "The vernal equinox and autumn are divided into national gifts, and scholars should not worship them. Folk activities are generally considered as the official start of an outing.
