The room you are using as a bedroom may not be the best for you and sleeping in your study or guestroom may be better from a fung shui perspective.
There could be several reasons for this. If the room looks onto a disruptive structure with significant cutting or sha energy, such as a bridge or construction site, it would be wise to move into a room that will provide you with more calm and tranquility.
If there is an en-suite in the room, note the position of the toilet door relative to your bed: is any part of your body in a direct line from the door? Are your feet pointing to the door when you are lying in bed? If you experience physical problems in the body parts that line up with the toilet door while you sleep - such as headaches, knee problems, digestion issues - then it is recommended that you move to a room with no bathroom attached.
As always, though, you need to take into account your own needs and requirements.
