DEPRESSION
Is depression more common at certain times of the year?

A: A form of depression called seasonal affective disorder (SAD) can come and go with the changing seasons. The exact cause of SAD is not entirely clear, although some research indicates that melatonin may be involved. Your body produces more of this sleep-related hormone in the dark. So shorter days, prolonged overcast weather, or darkened conditions at work can raise melatonin levels. This may have an effect on the occurrence of wintertime SAD.

You may have SAD if you experience some of the following symptoms during the same season for two years in a row: fatigue, oversleeping, less energy, less interest in usual activities, and excessive eating.

Light therapy and antidepressant medicines can be used alone or in combination to relieve the symptoms of SAD. Light therapy, the most common treatment, involves sitting for 20 to 60 minutes a day in front of a tabletop light box that simulates daylight.

Opening blinds at home and work, as well as spending time outdoors, can help you get more natural sunlight. Regular exercise also helps some people, especially in sunny weather. It’s important to consult your doctor for a diagnosis before trying any treatments yourself. But remember that if you do have SAD, it’s very treatable.
