Is light treatment of any benefit for non-seasonal depression?

It is well known that light therapy is of benefit to people who have seasonal depression. Now some practitioners are recommending light therapy for people who have non-seasonal depression. The few studies conducted indicate that light therapy is of some benefit for non-seasonal depression. Light therapy administered in the morning was of most benefit to depressed people who were also sleep deprived. The only mild side effect was hypomania in a few individuals. However, at the moment light therapy is considered a supplementary treatment and not a substitute for the established methods of depression treatment. If you want to try out light therapy speak to your doctor.
