Abstract

Sleep patterns remain a significant public health concern globally, impacting several aspects of life, including mental health. This scoping review examined how chronotype and circadian typology predict mental health, with sleep quality serving as a crucial mediator. While the importance of sleep is widely acknowledged, there is a lack of studies specifically investigating chronotype-aligned interventions to reduce psychological distress. To address the shortage, a comprehensive review of the peer-reviewed literature was conducted, identifying six papers for analysis. These studies mostly utilized cross-sectional designs to assess diverse global groups, including university students, healthcare workers, and military personnel. The results indicate that poor sleep quality is a major link between evening-oriented chronotypes and increased levels of depression and anxiety. Additionally, factors such as social jetlag were identified as key drivers influencing psychological strain, highlighting a divergence between internal biological rhythms and externally imposed societal schedules. This scoping review is unique and crucial since it identifies a significant gap in treatments. These findings highlight the urgent need for personalized adaptation strategies, such as chronotype-adjusted therapy, to align biological needs with societal expectations.
