That is really neat!

Haberman is a great neuroscientist but he is not a clinician. So what works in real life is not always the same-keep in mind when evaluating information, especially regarding sleep. As to evening sunlight, the short answer is yes, the sunset wavelengths are providing information to the eyes that it is days end. Additionally, new evidence suggests that the greater the daylight (doesn’t need to be direct sunlight) exposure the stronger the signal to the brain to ignore the later blue light exposure. Reason being the retinal melanocyte cells which record daylight get saturated at some point (research ongoing) so are immune to most blue light after sunset.

Andrew Huberman says that evening sunlight in eyes helps buffer the effect of screen time and lights later in the night. ❤️
