What are the advantages and disadvantages of people sleeping with their feet facing the window?

First, it is not good for breathing and sleep quality. When people sleep, their breathing will slow down and weaken. When the wind is a little stronger, it will affect their exhalation, and they will feel uncomfortable, which will not only affect their breathing, but also affect their sleep quality.

Second, create opportunities for microbes to invade the human body. When people sleep, their metabolism slows down, their reactions weaken and their immunity declines. When the wind is a little strong in the window, they will bring in a lot of microorganisms, and their nostrils are facing the window without any barrier.

Third, the change of light when facing the window will also affect the quality of sleep. To sum up, it is not superstition that sleeping feet can't "step on" the window, but a summary of human experience, which has scientific basis.

The advantage is that you can do whatever you want, and you can see the scenery outside the window first.
