109. Seasonal Depression: Vitamin D, Brain Health & Structural Roots of Winter Blues
Fri Jan 30 2026
Seasonal depression, often called “seasonal affective disorder”, can make getting through the Wintertime much more difficult. But what’s really happening in our brains and bodies when winter darkness sets in? How do our urban environments, work culture, and economic systems create the worst conditions for winter struggles. Shouldn’t we all be hibernating anyways?
In this episode, I explore the links between seasonal depression and Vitamin D, beyond simplistic explanations about light exposure, revealing fascinating connections between our environment, brain chemistry, immune function, and mental health. I’ll tell you a bit about my own experience as living in Berlin, a city with pretty minimal winter sunlight, has given me personal insight into how profoundly seasonal shifts can affect our mental and physical wellbeing.
The world needs all of us to be tuned in, feeling resilient, and able to support ourselves, our bodies, and our communities, especially right now, so let’s dive into what we can do.
