Clinicians have become aware that many people suffer from Seasonal Affective Disorder (S.A.D.). They become clinically depressed each winter, apparently, due to the decrease in light that occurs during winter months and to the corresponding increase in their bodies’ secretions of the hormone melatonin. One helpful treatment for this kind of depression is light therapy, treatment that provides S.A.D. sufferers with extra doses of light-levels they would be receiving from the sun if they lived closer to the equator. This video demonstrates light therapy and its dramatic impact on some persons with S.A.D.
