Answer to Question 2

Seasonal affective disorder (SAD) is characterized by episodes of depression that vary by season; most people are affected during the period from December to February. Symptoms include increased appetite and sleep, weight gain, interpersonal difficulties, and a heavy leaden feeling in one's limbs. Treatments include light therapy, which involves exposure to a light source for between 30 and 90 minutes a day. Light therapy has been found to be effective in a substantial portion of SAD cases.
