Precautions for health care at vernal equinox Spring belongs to mid-spring. At this time, liver qi is strong and kidney qi is weak. Therefore, it is necessary to abstain from acid and increase fragrance in diet, and tonify kidney and liver; At the same time, we should pay attention to the spleen and stomach, strengthen the spleen and eliminate dampness. The general principle is to avoid hot and cold, and strive for neutrality. You can choose a balanced diet according to your actual situation. For example, when cooking cold foods such as fish, shrimp and crab, we should add onion, ginger, wine and vinegar to prevent such dishes from being cold, damaging the spleen and stomach and causing abdominal discomfort after eating; When eating dishes that contribute to yang, such as leeks, garlic, papaya, etc. Eggs should be used to nourish yin in order to achieve the goal of complementary yin and yang.

Because of the alternation of cold and warm at this time, people are prone to high blood pressure, menstrual disorders, allergic diseases and so on. Pay special attention to the law of sleep and eat quantitatively to supplement yin and yang. You can gradually start morning exercises, and walking, jogging and tai chi are all appropriate. Although the weather gradually gets warmer after the vernal equinox, the temperature difference between day and night is large. According to the principle of "don't be extremely cold, don't be too hot", you should add clothes in time in the morning and evening, and get more sunshine on weekdays.

Will it be cold after the vernal equinox? It depends. Sometimes it's warm in bloom in spring, and sometimes it's cold in spring!

During the spring equinox, the average daily temperature is generally below 10 ~ 12℃ (the standards in different regions are different), 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.

In early spring, the temperature rises quickly, and then it stays low for a while. This weather phenomenon is called late spring cold. In the south, the main influence of late spring cold is the rotten seedlings of early rice. In the north, it will affect the growth of peanuts, vegetables and cotton, and seriously cause the phenomenon of wheat seedling death.

Don't think that after the vernal equinox, it will really be March of the vernal equinox. If you usually go out, you'd better bring some thick clothes in the morning and evening, because the temperature is still relatively low in the morning and evening. In addition, at this time, we should also adjust our diet, do a good job in protecting the liver and preventing dryness, and spend the spring healthily.
