October is not a season change.

The seasons usually change in March, May, August and November every year. Spring: March 3rd and a half; Summer: May and May; Autumn: August 15th and cover with a shirt; Winter: October and October.

Seasonal skin allergies often occur when the seasons change. Generally, the disease is more common in spring and autumn. Due to various environmental factors, allergenic substances such as bacterial spores and pollen scattered in the air will release a large amount of the compound histamine that is distributed in almost all tissues of the human body, causing nasal congestion, sneezing, runny nose, itchy throat, swollen eyelids and other phenomena.

Introduction to the four seasons

The four seasons refer to the four alternating seasons in a year, namely spring, summer, autumn and winter, each season lasts three months. Among the four seasons of the year, spring is March, April, and May; summer is June, July, and August; autumn is September, October, and November; and winter is December, January, and February. And January, April, July and October are often regarded as the representative months of winter, spring, summer and autumn.

The four seasons of the year are formed because the earth revolves around the sun. Due to the existence of the ecliptic angle, the annual change of the sun's direct point moving back and forth between the earth's north and south latitudes 23°26' causes seasonal changes in the height of the sun at noon and seasonal changes in the length of day and night, resulting in differences in the amount of solar energy obtained by various places. Seasonal changes lead to the change of seasons.
