What changes have taken place in the rain and solar terms?

The arrival of the rain solar term shows that the temperature has changed again. 24 solar terms was determined by the ancient people according to the temperature change, so what will happen to the weather with the arrival of the rain solar term?

After the rain festival, most parts of the country are cold and snowy. When it begins to rain, the rainfall gradually increases, which is beneficial to the greening or growth of overwintering crops. It is necessary to pay close attention to the field management of overwintering crops and make good preparations for seed selection, spring ploughing, fertilization and other spring ploughing and sowing. During the15th day of the rainy solar term, we went from the sixth day of July to the second day of September. "Eighty-nine swallows were planted in the river on July 9, and cattle were plowed everywhere on September 9 and September 19." This means that most areas in the northwest, northeast and southwest plateaus are still in the cold winter, and many other areas are experiencing or have completed the transition from winter to spring under the urging of spring breeze and rain.

However, in the rainy season, cold air activities in the north are still frequent and the weather is changeable. Since we talk about the frequent cold air activities in the next season, we can't help but mention what people often say about "spring cover". This is the principle of dressing and keeping in good health put forward by the ancients according to the characteristics of spring climate change. In early spring, when the sun is shining and the climate is getting warmer, people gradually go to cotton and wear light clothes. But at this time, it is still cloudy and cold in the north, and the temperature changes greatly. Although the rainy season is not as cold as the winter, the human skin has become relatively slack, and the resistance to the evil of wind-cold will also be weakened, so it is easy to get sick by evil. So it makes sense to pay attention to "spring cover" at this time. This changeable weather is easy to cause people's mood swings and even anxiety, which affects people's physical and mental health, especially those with hypertension, heart disease and asthma. In order to eliminate these unfavorable factors, besides continuing to cover them in spring, we should also adopt positive psychological exercise methods. Maintaining emotional stability plays a very important role in physical and mental health.

After the rain, the spring breeze warms up, and pathogenic bacteria and viruses are easy to spread with the wind, so infectious diseases tend to break out in spring. Everyone should protect themselves, pay attention to exercise, enhance their resistance and prevent diseases.

In the rainy solar terms, the humid atmosphere gradually rises, and dew and frost appear in the morning. Therefore, in view of such climate characteristics, diet recuperation should be based on conditioning the spleen and stomach, expelling wind and removing dampness. Because the climate is cold at this time, it can be supplemented appropriately, such as honey, jujube, yam and tremella, which are all suitable for this solar term.
