The SAD Episode

Seasonal Affective Disorder (SAD) is explored, distinguishing it from the common "winter blues" as a legitimate form of depression tied to seasonal changes. The discussion covers the two main types of SAD: winter-based, characterized by oversleeping and carb cravings, and the rarer summer-based, marked by insomnia and agitation. The hosts delve into the biological mechanisms behind SAD, focusing on the roles of serotonin and melatonin, and how imbalances in these chemicals, triggered by reduced sunlight, can lead to depressive symptoms. They also address social and environmental factors, such as negative associations with winter, that can exacerbate the condition. Treatments like bright light therapy, SSRIs, and cognitive behavioral therapy are examined, alongside the curious case of Tromsø, Norway, where a positive winter mindset seems to mitigate SAD despite prolonged darkness.
