Sleep, Sleep Architecture and Mental Health

This course explores the relationship between sleep and psychological wellbeing through two complementary perspectives. In conversation with psychologist Maria Ruberto, we examine sleep architecture, sleep cycles, circadian rhythms, sleep regularity, emotional processing and the practical implications of disrupted sleep. We then examine findings from a large UK Biobank cohort study of almost 96,000 adults, exploring how objectively estimated sleep duration, regularity, fragmentation and sleep architecture were associated with subsequent disease—including anxiety and depression. Together, the conversation and research highlight why sleep is an important component of mental health assessment and why both the quantity and pattern of sleep deserve clinical attention.

  • Describe the basic architecture of sleep, including the progression through non-REM and REM sleep across the night.

  • Explain the relationship between sleep and circadian rhythms, including the importance of daytime light exposure and sleep regularity.

  • Identify the potential roles of sleep in memory consolidation, emotional processing and psychological wellbeing.

  • Recognise the clinical significance of sleep duration, sleep regularity and sleep fragmentation when assessing mental health.

  • Summarise key findings from a large UK Biobank cohort study examining objectively estimated sleep characteristics and subsequent disease risk.

  • Critically interpret evidence concerning sleep and mental health, including the distinction between association and causation and the limitations of wearable-derived measures of sleep architecture.
