In this episode of Sunlight Matters, hosts Dave and Georg welcome Swedish sleep and light researcher Arne Lowden for a fascinating conversation about the science of light, circadian rhythms, and how our bodies and minds are profoundly shaped by solar exposure.

Dr. Lowden, author of the book Survive the Winter, shares powerful insights into how lack of natural light affects sleep, mood, and long-term health, especially in northern climates. We explore the hidden costs of indoor living, the realities of “social jet lag,” and the rising demand for light therapy as a natural solution to Seasonal Affective Disorder (SAD).

Whether you're designing a sun-filled home, optimizing your daily habits, or just trying to shake the winter blues, this episode offers practical, research-backed guidance to help you reconnect with the sun and realign with your natural rhythm.
