It's hard to rest with too much active energy around you. You have to be aware, for example, of what electricity is running behind your bed. Try to minimize it with a battery-operated alarm clock instead of an electric one. Turn off your phone at night and keep it out of the room. No laptop or computer near the bed. An hour before you go to sleep, stop looking at it.
This is a little similar to having your bedroom right above a kitchen stove. Some say the fire energy from the kitchen stove can cause insomnia and other health problems arising from lack of sleep. A more scientific explanation is that the wall transfers heat from the kitchen, which in turn reduces your sleep quality. Also, the sound of the refrigerator and water moving to the kitchen can all bring noise to your bedroom.
Be aware of the position of the windows. If you can, try to avoid placing your bed between the window and a door, or you'll be in the middle of the "draught" of chi running between these two places. If you can't avoid it, just make sure you have nice, pleasant curtains to block some of the bad energy. You should also avoid sleeping facing the window, if you can, or your sleep won't be as restful.
Everyone appreciates the benefits of beautiful, comfortable living environments; America’s billion-dollar interior decorating industry attests to this fact. However, Feng Shui takes the approach that your surroundings affect not just your level of material comfort but also your physical and mental health, your relationships, and your worldly success.
Historically, feng shui was widely used to orient buildings—often spiritually significant structures such as tombs, but also dwellings and other structures—in an auspicious manner. Depending on the particular style of feng shui being used, an auspicious site could be determined by reference to local features such as bodies of water, or stars or the compass.
