LOADING ERROR LOADINGSometimes, it feels like there’s a battle taking place between “night owls” and “early birds”, sometimes called “larks”. AdvertisementHow many of us are “night owls” or “early birds”? According to Dr Breus, only 15% of us have a natural “early bird”-style chronotype, and roughly the same amount are “night owls”. And while they didn’t use the ‘bear’ term, a 2012 paper found that as much as 60% of the population has a “mixed” chronotype (neither night owls nor early birds). Women are slightly more likely to be “early birds” than men.
