A widely quoted motto “Early to bed and early to rise makes a man healthy, wealthy, and wise” was rarely and inconclusively examined in chronobiological research. To test associations of morningness-eveningness with self-assessed health status, depression, anxiety and somatic complains, 1969 adults were chronotyped on Evening and Morning lateness scales (E and M) of the Sleep-Wake Pattern Assessment Questionnaire. Health was found to decline from the best in long active type (with positive E score) though moderate in morning and evening types (with none and both positive scores, correspondingly) to the worst in short active type (with positive M score). Despite linear association with long/short active types, self-reported sleep length exhibits a U-shaped rather than linear relationship with health problems. It is concluded that the difference between E and M scores, but not their sum, predicts self-assessed health: healthier respondents prefer earlier wake up times and later, but not earlier bedtimes.
