LONDON, ENGLAND – Late risers and late sleepers may have higher risks of depression, according to a recent study conducted by scientists at the University of Surrey. The research aimed to delve deeper into understanding the correlation between one’s natural sleep-wake cycles, known as chronotypes, and mental health.
The study surveyed a group of 546 undergraduate students to determine their chronotypes, with results showing that only 38 participants were classified as ‘early birds’ with a morning chronotype. On the other hand, 252 individuals exhibited a preference for evening activities, while 256 fell in the category of an intermediate sleep-wake cycle. These findings align with the typical distribution of chronotypes among young adults, where eveningness is more common.
Participants were also questioned about various factors including sleep quality, rumination, depression symptoms, mindfulness, and alcohol consumption. Notably, individuals with an evening chronotype displayed significantly higher levels of depressive symptoms compared to their intermediate-type counterparts. The study pointed out that rumination, or the tendency to dwell on negative thoughts, played a role in this connection.
Further analysis of the data revealed that mindfulness qualities, particularly ‘acting with awareness’ and ‘describing,’ had indirect effects on the relationship between depression risk and chronotype. Researchers highlighted the importance of mindfulness interventions, better sleep quality, and reduced alcohol use as strategies to mitigate depression risks associated with being a night owl.
The findings suggest that enhancing mindfulness efforts, such as guided meditation and mindfulness exercises, could be beneficial in reducing depression symptoms among individuals with an evening chronotype. Additionally, focusing on improving sleep quality and minimizing alcohol consumption may also contribute to better mental health outcomes. These insights provide valuable avenues for potential interventions to address the mental health implications of differing chronotypes.
The research, published in PLOS One, sheds light on the complex interplay between sleep patterns, mental well-being, and lifestyle factors. By identifying actionable strategies to support individuals with an evening chronotype, the study offers hope for those struggling with depression symptoms related to their natural sleep preferences.
