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

Area of Science:

• Chronobiology
• Psychology
• Genetics

Background:

• Individuals preferring later daily activity (Evening types) generally report poorer well-being compared to those preferring earlier activity (Morning types).
• Existing research suggests shared genetic, biological, developmental, and psychosocial mechanisms may underlie this chronotype-well-being association.

Purpose of the Study:

• To critically summarize proposed explanatory mechanisms linking chronotype and well-being.
• To propose an integrated interdisciplinary biopsychosocial framework for understanding these associations.

Main Methods:

• Literature review and critical synthesis of existing research on chronotype and well-being.
• Analysis of proposed genetic, biological, developmental, and psychosocial factors.

Main Results:

• Evening types consistently demonstrate lower well-being across various measures compared to Morning types.
• Multiple interconnected mechanisms are implicated, requiring an integrated approach.

Conclusions:

• The relationship between chronotype and well-being is complex and multifactorial.
• An interdisciplinary biopsychosocial framework is essential for a comprehensive understanding and future research.
