Circadian Light Insights
Setting your circadian clock requires direct sunlight, as exposure through windows significantly reduces light intensity. Conducting simple experiments with a light meter app reveals how much lux is lost when viewing through glass. Interestingly, prescription lenses enhance light focus on the retina, unlike windows that scatter and filter essential wavelengths. Emphasizing outdoor time is crucial for optimal biological functioning.In this clip

If light exposure is a matter of lux accumulated over time, why would viewing sunlight through a window, where you measure 10,000 lux, not be enough light to achieve the 100,000 lux mark in the episode Using Science to Optimize Sleep, Learning & Metabolism | Huberman Lab Podcast #3 and the clip Circadian Light Insights?
