A good Feng Shui tradition is not to place your bed directly under or parallel to the window. Noise and light coming from the window may raise your alertness and affect your natural sleep cycle. However, what if it is not possible to put the bed anywhere else? You can minimize negative effects with the help of proper window treatments and a headboard. The best headboard is made of solid upholstery or wood and should have rounded edges. For good feng shui, use window coverings made from heavy and solid fabric to block light during sleep, in combination with sheer curtains for sense of flow and softness. Natural materials, such as linen or cotton, are preferred.
