When is the first frost in 2022 and the first frost tomorrow?
On the national average, the first frost is the season with the largest temperature difference between day and night in a year. The first frost solar terms are characterized by cold weather in the morning and evening, hot weather at noon, large temperature difference between day and night, and obvious autumn dryness. The first frost doesn't mean you need first frost to enter this solar term. In fact, frost didn't fall from the sky. Frost is the condensation of water vapor on the ground when it meets cold air due to the change of temperature difference. The solar term "first frost" has nothing to do with first frost, they are not the same concept.
The solar terms in the first frost mainly include the customs of enjoying chrysanthemums, eating persimmons, climbing high and overlooking, and tonic. The first frost season is the turning point of autumn and winter climate, and it is also the transition of the spirit of the sun from being hidden. The key to health care should pay attention to "keeping out the cold outside and clearing heat inside". There is a folk saying that it is better to make up the first frost in winter. In autumn, the spleen and stomach are the foundation of the day after tomorrow. At this time, tonic is appropriate, especially strengthening the spleen and nourishing the stomach to nourish the day after tomorrow.
