You will get hot on rainy days.

Everyone will react to cloudy rain (weather change), but the older they are, the more obvious their reaction will be, because the process of cloudy weather (weather change) is the process of the weather changing from stable to sharp (mathematically called "increase of change rate"), and the human body will be dominated by the law of "correspondence between man and nature". In addition to "whole body fever", you can also see "whole body ache" in the physical reaction of rainy days (bad weather) in cloudy days; There is another obvious example: when it rains on cloudy days, a person who has had an operation will have an itchy wound and even obvious pain. In a word, man and nature are closely related and mysterious, and the relationship between man and nature is endless.
