Horne–Östberg Chronotype Score
The Horne–Östberg chronotype score classifies morningness–eveningness via questionnaire—useful with sleep logs, not a substitute for tracking real peaks.
The Horne–Östberg chronotype score is a short questionnaire that classifies morningness–eveningness on a scale from definite evening type to definite morning type. It helps explain why generic 5 a.
m. challenges fail for owls and why some larks wilt at night games.
Scores are self-report, not lab gold standard—pair with two weeks of sleep and performance logs.
