After the autumnal equinox, the position of direct sunlight moves south, and the days in the northern hemisphere become shorter, the nights become longer, the temperature difference between day and night increases, and the temperature drops day by day.

Two or three things about "I" and "Autumn Equinox"
We know the story and legend of the autumnal equinox, so let's learn about the relationship between human beings and nature, that is, what should we pay attention to during the autumnal equinox?
It's the end of August before the autumnal equinox, and it's still about a month away from it. Now I am in the south of Guangxi, and the temperature is still relatively hot. I heard that it is still hot in some places, and the electricity has been cut off. So before the autumnal equinox, we still need to endure the hot summer weather. I found that since June, my electricity consumption began to increase sharply, and it is expected to reach the peak of the whole year in July and August, and the electricity consumption began to fall in September, especially in the week before the arrival of the solar term in September.
According to the characteristics of solar terms after the autumnal equinox, there is residual heat before the autumnal equinox, so it is more common to be warm and dry; After the autumnal equinox, bursts of autumn wind hit, causing the temperature to drop gradually and the cold to get heavier and heavier, so there was more coolness and dryness. In short, after the autumnal equinox, the temperature generally drops and the hot summer weather recedes. According to my experience, in our southern region, after the autumnal equinox, parents who take their children to school by electric car need to wear a long-sleeved shirt, explosive coat and so on in the morning. Because the temperature is low in the morning, explosive long sleeves can prevent children from catching cold.
Diet and physical exercise. Because it is autumn equinox, it still belongs to autumn. The weather is dry in autumn. In order to prevent dryness, we must keep exercising. In particular, students must adhere to simple exercises such as running and skipping rope to enhance their physical fitness and improve their disease resistance. Before and after this solar term, you must drink more water, eat more fruits, pay attention to a light diet, and eat less or no indigestible food such as barbecue and midnight snack to prevent evil dryness from invading your body and keep your health.
