From a Feng Shui perspective, if the master bedroom bed directly faces the large bay window, will there be any adverse effects? How to resolve it?

You don’t need to think too much about Feng Shui. If it’s a new home and you feel uncomfortable sleeping, it’s either a decoration problem or a problem with the bed furnishings. As for the decoration problem, just ventilate it during the day and bedside. Place a pot of cactus. If it's a bed, try orienting it east-west with your head facing east. It will be better to hang a mirror on the wall facing the window in your home, but the one opposite the mirror will not be so good. It depends on how you measure it. If it is a floor-to-ceiling window, I suggest you build an ecological fish tank at the bottom. , put more water plants or stick fish tank paper on the outside. As for the curtains, use velvet red. I don’t know if you understand and are satisfied with this answer.
