In this episode, we delve into the complexities of Seasonal Affective Disorder (SAD), a subtype of Major Depressive Disorder that fluctuates with the seasons. Seasonal Affective Disorder, a condition affecting millions during the darker months. We explore its symptoms, causes, and demographic prevalence, highlighting its impact on mood, cognition, and physical health. The episode also examines leading theories behind SAD, such as disruptions in circadian rhythms and hormonal imbalances linked to reduced sunlight exposure, and the biological underpinnings. We then move to existing treatment options, including light therapy and cognitive behavioral therapy. With limited clinical trials, the episode underscores the importance of advancing research into effective interventions.
