No form of artificial lighting can match the natural wonders of sunlight, so we must try to allow light and air to come into our home from outside.

· Keep windows clean and check that they all are open.
· Draw curtains back as far as possible and keep blinds up during the day.
· Move away plants or objects which obstruct light coming into your room.
· Use mirrors opposite to windows in rooms with low light levels.
· Use low-energy lighting or full-spectrum lights where possible.
· Create skylights, atrium, and sun rooms where you can, so that you can enjoy the benefits of sunlight.

Coloured Lights
· Blue light is exceptionally soothing and cooling. Use it in hot rooms, or when you are suffering from anger or a fever.
· Green light is very cooling and soothing but is not recommended when you wish to read or concentrate on a task.
· Orange light is warming and stimulating. It creates an atmosphere of happiness and vitality.
· Pink light has muscle relaxing qualities. It is also a gently warming and loving colour.
· Red light is physically warming and emotionally arousing, so it is also associated with sexual passion.
· Violet light bulbs can help harmonize your mental and emotional state.
