The vernal equinox and solar terms divide day and night equally, and the cold and summer are distinct. People should pay attention to maintaining the balance of yin and yang in health care. Stalin said: "Relatively static objects and the possibility of temporary balance are the fundamental conditions for material differentiation and therefore life". In order to obtain the "basic conditions of life" of this "temporary balance state", maintaining the balance of yin and yang in the human body has become an important rule of health preservation. This rule is very important in spirit, diet, daily life, self-care and medication. How to use the law of yin-yang balance in health care, coordinate various functions of the body, achieve a balanced state inside and outside the body, and keep the organic whole of the human body relatively calm and balanced is the foundation of health care.

Be diligent at the vernal equinox.

"Wheat rises at the vernal equinox, and every moment is worth 1000 yuan." In the northern areas with little rain in spring, we should pay close attention to spring irrigation, water saving and jointing fertilization, and pay attention to preventing late frost and freezing injury. South China still needs to continue to do a good job in drainage and flood prevention. Early rice seedling raising in Jiangnan and Jianghuai areas has started, and the weather changes frequently in early spring. Attention should be paid to soaking seeds to accelerate germination when cold air comes, and sowing in sunny days when cold air ends. The experience of the masses says, "A cold tail warms the head, so there is no need to worry about seedlings." According to the weather conditions, strive for 3-5 sunny days after sowing to ensure that all seedlings are sown at one time. Spring tea has begun to sprout, so it is necessary to apply quick-acting fertilizer to control pests and diseases in time and strive for high yield and high quality tea.

"February is the vernal equinox, and planting trees and fertilizing farmland is deep." The vernal equinox is also a good opportunity to plant trees. In ancient poems, there is a saying that "Niu Jiao girls started planting trees in the middle of the night, and it was the vernal equinox in the Ming Dynasty". In the hot busy farming season, we should continue to use our hands to green the mountains and rivers of the motherland and beautify our environment.

Sow at the right time at the vernal equinox

The vernal equinox is one of the solar terms reflecting the changes of the four seasons. In ancient China, beginning of spring, Changxia, beginning of autumn and beginning of winter were used to indicate the beginning of the four seasons. The vernal equinox, summer solstice, autumn equinox and winter solstice are in the middle of each season. On the vernal equinox, the sun shines directly on the equator, and the time between day and night is equal all over the earth. Therefore, the ancient vernal equinox and autumnal equinox are also called "equinox", and there is a folk proverb that "vernal equinox and autumnal equinox are equally divided day and night".

After the vernal equinox, the overwintering crops in most parts of southern China entered the spring growth stage. In central China, there is an agricultural proverb, "Wheat starts at the vernal equinox, and every moment is worth a thousand dollars". The temperature in most parts of the south continues to rise, but generally it doesn't rain as fast as the vernal equinox. In late March, the average temperature in northern South China is mostly 13℃ to 15℃, and in southern South China it is mostly 15℃ to 16℃. Most of the plateau has been melted by snow, and the ten-day average temperature is about 5℃ to 10℃. Most areas in South China, such as river valleys, have the highest temperature, with an average of 18℃ to 20℃.

In the south, except for the marginal mountainous areas, the average daily temperature rose steadily to above 12℃ in 1978, which is beneficial to planting crops such as rice and corn, and is also very suitable for afforestation. However, before and after the vernal equinox, there is often a strong cold air intrusion in South China, and the temperature drops obviously, as low as 5℃. Sometimes a small stream of cold air comes one after another, forming a low temperature and rainy weather that lasts for several days, which is not good for agricultural production. According to this feature, we should make full use of the weather forecast, grasp the cold tail and warm head, and sow in time.

The spring equinox exercise should be appropriate.

Exercise is not sweating as much as possible. Some people sweat easily, sweating a little during exercise, while others sweat a little after a long exercise. What is the reason?

Generally speaking, the amount of sweating is related to the intensity of exercise. The greater the exercise intensity, the more you sweat, and vice versa. In addition, everyone's physical condition is different, so the amount of sweating is also related to personal physical condition; The less the number of sweat glands, the less sweating; On the contrary, the more you sweat, the more you sweat. People with good physique are muscular and have good endurance. Even if they exercise a lot, they won't feel particularly tired and sweat less. People with poor physique are not good at sports, even a little exercise will make them breathless and sweat more. Drinking water before exercise will also affect the amount of sweating. The more water you drink before exercise, the easier it is to sweat.
