What is the division of seasons?

According to the climate season, the daily average temperature or moving average temperature is greater than or equal to 10℃ and less than 22℃ in spring, greater than or equal to 22℃ in summer, less than or equal to 10℃ in autumn and less than 10℃ in winter.

The climate season division index is based on the waiting temperature method proposed by Mr. Zhang Baokun in 1934, and it is still used in meteorological operations. In ancient China, five days was called waiting period, and waiting temperature was the average temperature of five days. However, in the division of climate seasons, it is not a fixed five days, but a five-day moving average, that is, the average value is calculated by taking the current day and the first four days as a group.

Matters needing attention in autumn and winter sports

Autumn and winter are not suitable for high-intensity sports. In order to keep a good figure, we must develop good exercise habits and exercise at a fixed time and time, which will help improve the adaptability of the body in autumn and winter and make the exercise achieve better results. It's like eating. Irregular diet is easy to get stomach trouble.

Be sure to relax after exercise: this seems to be something you should pay attention to in any season. When relaxing, stretching your muscles and joints can not only relieve the lactic acid produced by joint movement, but also provide a buffer for each joint from the moving state to the stopping state. For example, drunkards love to brag. We all drink white wine, and then drink a few bottles of beer to gargle and buffer.
