AT 8 AM, sun worshippers already lay prostrate on the shimmering oceanside beach at Amelia Island, Fla. In a dark, windowless room nearby, present-day priests at the temple of the sun, members of the Society for Light Treatment and Biological Rhythms (SLTBR), convened for rites of their own: a review of advances in their field.
Timed exposure to daylight-intensity light has become the treatment of choice for seasonal affective disorder (SAD), according to Anna Wirz-Justice, PhD, professor of psychiatry at the University of Basel in Switzerland. "Light is as effective as antidepressant medications are, perhaps more so," said Wirz-Justice, who cochaired a roundtable session at the SLTBR's annual meeting, held in conjunction with the Society for Research on Biological Rhythms (SRBR) in May.
