Phototherapy (Light Therapy) To Help With Depression
Some people have seasonal depressions that recur regularly in the winter and appear to be associated with a reduction in daylight hours (seasonal affective disorder, or SAD). These depressions
fade away as spring approaches and may be followed by a period of mild
hyperactivity. There is considerable support for exposure to
bright light being an effective treatment for winter depressions.
Individuals usually sit about 3 feet away from 6 to 8 florescent
bulbs-ordinary room light is too dim to be effective.
After several days of exposure (usually from ½ to 2 hours daily), the depression improves
and remains improved as long as treatment continues. Although
this approach is still under investigation, many clinicians are
recommending it for this particular type of depression. Treatment
should be under the supervision of a professional who is experienced
with SAD and its treatment.
