A tight sleep is the best medicine. To improve your sleep try to use the magic of colors while decorating the interior of your bedroom. According to Feng shui each cardinal direction has its unique color. A room which is situated in the south-east or east will look more cozy with brown or green walls. The south-west or north-west direction of your room location require dark brown or yellow colors. If the windows of your room face north choose all the shades of blue from turquoise to navy blue for the interior. The west direction requires white decorations and accessories. But one should think twice before painting the walls or buying the wallpaper.
