Scientifically speaking, if you stay under the window for a long time in autumn, you will catch a cold. The so-called evil wind invasion refers to this.
Also, in the north, when it snows. When the snow stops, look at the angle of 180 degrees and you will see that there is no snow!
Distance strength is 2-3 cm. It is the highest point of integrated snow!
Although there is no scientific reason, it is also very convincing from experience. In fact, if people sit or lie under the window when they are sweating, they are easily exposed to the wind, which is what people often say, that is, when people sweat, their pores are open, and the wind under the window is a small area, so if it blows into the body, it will be very uncomfortable, not just under the window.
