It's really a no-no to have a window by the bed. Scientifically speaking, the head of the bed is not good for feng shui, the sun is exposed, the air circulation is fast, and the temperature is unstable. Windows are the most unbalanced place between yin and yang. It is hot in the daytime and cold in the shade at night, which will do harm to people's health over time.
Suggestion:
1, remove the bed, but not facing the door, facing the window and the door. Also be careful not to cross the beam coping.
2. If conditions permit, close the window. If you really can't, open the window less, especially when you are resting. Pay attention to sealing, clean frequently and keep clean. In addition, if there are psychological hints, put a copper gourd on the bedside, and pay attention to the curtains not to be pervious to light.
I hope my answer can help you, thank you.
