Morning Phototherapy involves exposure to bright light upon awakening. It helps to increase morning alertness and advances the sleep phase in the evening. An inexpensive way to get exposure to bright light (depending on weather conditions, the location and season of the year) is to open the window shades or take a walk in the bright morning sun. Alternatively a specially designed bright light box may be prescribed. These boxes provide between 2,500 and 10,000 lux . Depending on the brightness level, they are used for periods of 30 min to 2 hours. Precise timing of use is critical and is related to the core body temperature minimum. The light is administered about 30 minutes earlier every other day to help gradually advance evening sleep onset. This treatment can be effective in 2 to 3 weeks when combined with evening light avoidance, but often requires ongoing treatment to maintain gains.
