Light and Mood
Bright light exposure significantly influences mood, with sunlight providing over 100,000 lux at noon, compared to much lower levels indoors. Even on cloudy days, the circadian clock continues to sum photons, integrating light over time. Understanding this mechanism highlights the importance of natural light for mental health, especially in combating seasonal affective disorder.In this clip

What does Andrew Huberman recommend for accumulating 100,000 Luxx minutes of light exposure in the morning in the episode Using Science to Optimize Sleep, Learning & Metabolism | Huberman Lab Podcast #3 and the clip Circadian Light Insights? Is the recommendation of five minutes if the illumination from the sun is 20,000 Lux or about 15 minutes if the illumination is 7,000 Lux still valid for quantifying how much time I need to spend getting light exposure based on the brightness of the sun on a given morning?
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?
How many lux are there in sunlight?
