An Interdisciplinary Perspective on the Association Between Chronotype and Well-being.

Individuals with a circadian preference for mental and physical activity later in the day ("Evening types") are consistently found to fare worse on most facets of well-being than individuals with a circadian preference for mental and physical activity earlier in the day ("Morning types"). Several explanatory hypotheses of this association between chronotype and well-being have been proposed, including shared genetic, biological, developmental, and psychosocial mechanisms. This paper presents a critical summary of these explanatory mechanisms and offers suggestions for their integration in an interdisciplinary biopsychosocial framework.
