    Ironic mascot given @duolingo's unfriendly to night owls. Days are divided at midnight, though biological midnight is ~3am for most adults. Also use lesson end time instead of start to decide which day, even if most was done before

Abstract Synopsis

  • The study investigates how social factors influence sleep patterns, using a smartphone app called ENTRAIN to collect global sleep data.
  • The research reveals that societal pressures can delay bedtimes and reduce overall sleep duration, with average bedtimes being a key predictor of sleep length.
  • Additionally, findings indicate that age significantly impacts sleep timing and habits, with women generally getting more sleep, and outdoor light exposure leading to earlier bedtimes.
