Do you notice a shift in your mood when the days are shorter and darker? If so, you're not alone.

It’s not uncommon to experience stress, anxiety or even depression during the winter months. Each year, about 10% of adults in the United States experience seasonal affective disorder (SAD). The condition can reflect a change in serotonin levels and be linked to depression.

Matt Southward, an assistant professor in the Department of Psychology in the College of Arts and Sciences at the University of Kentucky, is researching treatment outcomes for those coping with anxiety, depression and personality disorders. He also works in the Treatment Innovation for Psychological Services Lab.

On this episode of "Behind the Blue," Southward discusses the signs and symptoms of those winter blues, habits people can try to develop to help cope with stress and anxiety, tips on recognizing when seasonal depression may require professional help, and more.
