What about accumulating 100,000 Lux minutes of light exposure in the morning as recommended by Andrew Huberman in the episode Using Science to Optimize Sleep, Learning & Metabolism | Huberman Lab Podcast #3 and the clip Moonlight and Circadian Rhythms? He suggested five minutes if the illumination from the sun is 20,000 Lux or about 15 minutes if the illumination is 7,000 Lux. Has this concept changed in subsequent episodes of the Huberman Lab Podcast, specifically regarding the recommendation 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?
