Feng shui, which originates in the Chinese philosophy of Taoism, instructs on how to arrange rooms, furniture, offices, houses, and other arrangements to maximize favorable energy flow throughout living spaces. Here are some recommendations that may help promote relaxing sleep:

Try not to have the bed in a corner of the room. The corners are where energy tends to be stagnant.
Avoid putting your bed next to a window. Energy can be drained this way.
The bed shouldn’t be positioned so that the soles of the feet, when lying face-up in bed, directly face the doorway.
When lying in bed, you should have full view of anyone coming in the door. If you can’t do this directly, hang a mirror to reflect the entranceway.
Try to avoid facing sharp corners from desks, bookcases, and other pieces of furniture.
