the distinction between larks and night owls is a robust psychological finding that predates iphones; there is some evidence to suggest it is genetic; and night owls represent a significant percentage of the population (about 20%). that isn't to discount the point about blue light exposure.
- magnamerc 7y agoNight owls are absolutely real and they are genetically predisposed. In fact, night owls will always be night owls and there's really nothing you can do about it. Everyone should read Dr. Matthew Walker's book 'Why We Sleep'.
- dpeck 7y agoIt fits "just so" like a lot of evolutionary biology hypothesis but it does seem that there would be an advantage to have some portion of the population that spent a significant part of their waking hours after dark. People to keep the fires going, to keep away predators, warn the rest of the group of danger, etc.
