How to Choose a Light Box for Treating Seasonal Affective Disorder

People suffering from Seasonal Affective Disorder, or SAD, find themselves becoming depressed and lethargic during the winter months when the days are shorter and there is less light available. Many people find relief by using a specially designed lamp or light box to increase their exposure to light, thereby boosting their mood and energy levels.For a light box to be effective at treating Seasonal Affective Disorder, it must be very bright, between 2,500 and 10,000 lux (most household lighting is around 500 lux). Bright light is the best choice for replicating natural sunlight. A full spectrum or ultraviolet light is not necessary, and most light boxes use a fluorescent light bulb.

Instructions

• 1

  Look for a box with a diffuser screen on the front. This will reduce glare and help prevent eyestrain while using the light box.

• 2

  Positioning of the light box should be at eye level, so you should look for a model that will work best for you. Where will you be receiving your light therapy? Do you have a table you can set your light box on, or will you need a light box that comes with a floor stand?

• 3

  Follow your doctor's instructions on using the light box. The general course of treatment is one 20- to 60-minute session every day, preferably in the early morning. You do not need to look directly into the light box. Light therapy is generally considered safe. Side effects may include insomnia, irritability or feeling "wired." If you experience these symptoms, reduce your light therapy sessions and talk to your doctor.
