Philosophical truth of wearing short sleeves in hot weather and down jacket in winter

The proverb is "February and August, dressing indiscriminately".

In our country, this sentence is used to describe the great difference in the thickness of clothes when people are outdoors in early spring and early autumn. Recently, you can see in the street that some people are wearing thin coats, while others are down jackets and coats, which are tightly covered.

February and August are the turn of the season, when it is warm and cold at first, the temperature difference between day and night is large and the wind direction is changeable. If you take off your winter clothes too early at this time, once the temperature changes, it will be difficult to adapt and your body's resistance will drop.
