Disadvantages of sleeping with feet facing the window:
1. It is detrimental to breathing and sleep quality. Breathing will slow down and weaken when a person sleeps. A slightly stronger wind will affect exhalation and make the person feel very uncomfortable, which affects both breathing and sleep quality.
2. Create opportunities for microorganisms to invade the human body. When people sleep, their metabolism slows down, their reactions are weakened, and their immunity decreases. When the wind outside the window is slightly stronger, a large number of microorganisms will be brought in, and there will be no barrier to the nostrils facing the window.
3. Light changes. Light changes when facing the window will also affect the quality of sleep. In summary, it is not a superstition to "step on" the window with your feet while sleeping, but a summary of human experience and has scientific basis.
The advantage is that you can do whatever you want, and you can see the scenery outside the window first when you get up
