Now that we’ve turned back our clocks, it’s time for shorter days — and for many, that also means the onset of seasonal affective disorder, or SAD. This week, host Paula Felps sits down with world-renowned researcher and psychiatrist Norman Rosenthal, the doctor who was instrumental in identifying SAD and also pioneered light therapy as treatment. His new book, Defeating SAD: A Guide to Health and Happiness Through All Seasons, provides a roadmap for beating this disorder and in this episode, he explains how we can better prepare for the next few months.

In this episode, you’ll learn: 

• How Dr. Norm’s own experiences with seasonal affective disorder inspired him to research it.
