Summary
Most people take the light in their life for granted. People wear dark glasses to block light during the daytime and nothing on their eyes at night. This gives the retina in the eye the signal that night time when its really daytime and that its daytime when its really night time. This small example illustrates how disconnected humans have become with their environment and this circadian mismatch coincides with the rise in neolithic diseases. Dr Alexander Wunsch has been studying the science of photobiology for decades and joins us to share his thoughts on how we can improve our relationship with light, both natural and artificial.
Key Points
- Impact of light exposure on health and circadian rhythm
- Alternative perspectives on cancer prevention and treatment
- Practical health optimization strategies discussed
- Evidence and experience-based supplement recommendations
- Holistic approach to understanding chronic health issues
Key Moments
Indoor lighting should mimic cave fire at 2700K or below
Dr Alexander Wunsch recommends that indoor lighting should never exceed 2700 Kelvin warm white, mimicking fire or cave lighting. Higher color temperatures indoors trigger stress hormones like cortisol and adrenaline that are designed for outdoor activity, creating a mismatch when sitting at a desk.

Modern civilization has a universal light problem
Dr Wunsch explains that everyone living in modern civilization has a dysfunctional relationship with light, spending 90-95% of their time under artificial lighting that lacks the natural qualities of sunlight. Even window-filtered daylight is significantly altered.
"say we are exposed uh to artificial"
Thermal light sources are our evolutionary norm
Dr Wunsch explains that for hundreds of thousands of years, humans were exposed only to thermal light sources like fire and sunlight. Modern artificial lights are cold light sources with arbitrary spectra that our bodies never evolved to handle.
