Duration of Treatment
Light therapy reduces the production of melatonin and increases serotonin, thereby having a positive effect on mood. Treatment is commonly initiated in fall when weather conditions change and the sun begins to disappear. Light therapy usually ends in spring when weather conditions improve and there is sufficient sunlight.
Light therapy can begin to produce positive results within two to four days of commencing treatment and commonly reaches its full effectiveness within two weeks. SSRIs can require four to six weeks to achieve full effectivity.
