Seasonal Affective Disorder (SAD)

Have you ever noticed how the weather can affect your mood? Perhaps you feel happier on a sunny day, or sad on a cloudy day. These shifts in our mood do not generally affect our ability to cope with our daily life. However, some people are more vulnerable to a type of depression that follows a seasonal pattern. This condition is called Seasonal Affective Disorder, or SAD.

SAD is a kind of depression that appears at certain times of the year. It usually begins in the fall when the days get shorter and lasts through the winter. A less common form of Seasonal Affective Disorder affects people in the summer months and usually starts in the spring. It isn’t really clear what causes SAD, but it’s thought that winter SAD may be caused by lack of sunlight. But this may not be the whole answer, as it’s also thought to run in families: 13–17% of people who develop SAD have an immediate family member with SAD.

It’s normal to have some days when you feel sad or down but if these feelings of sadness are lasting for days at a time, or are interfering with your ability to follow through with the daily activities that you normally enjoy, then you should reach out for support, or see your doctor. To diagnose SAD, your doctor may do a complete evaluation which may include a physical exam, lab tests, and psychological evaluation using the criteria listed in the Diagnostic and Statistical Manual of Mental Disorders (DSM). Treatment may include light therapy, medications, and psychotherapy.

Whether you’re experiencing SAD or just looking to boost your mood through the long, cold, winter months, there are some things you can do. Try participating in an exercise program or engaging in another form of regular physical activity, get outside, make healthy choices for meals and snacks, and connect with friends or loved ones!
