Moonlight and Circadian Rhythms
Moonlight, candlelight, and fireplace flames do not disrupt the circadian clock, allowing for safe nighttime enjoyment. The sensitivity of certain eye neurons adjusts throughout the day, meaning these light sources won't trick the brain into thinking it's daytime. While bright moonlight may have some effect, it’s generally not a concern for sleep disruption.In this clip

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?
