Episode Overview
In this comprehensive conversation, Professor Colin Espie, Professor of Sleep Medicine at the University of Oxford, shares expert insights on how to sleep better naturally. With over four decades of clinical experience, Professor Espie explains the fascinating science behind sleep stages, debunks common myths, and provides evidence-based strategies for improving sleep quality. This episode covers everything from understanding your individual sleep needs to practical techniques for falling asleep faster and maintaining healthy sleep hygiene.
Key ‘How to Sleep Better’ Insights:
- Sleep as an Involuntary Process: Sleep functions like breathing—it’s something that happens to us naturally rather than something we can force, which is why trying to sleep often backfires and disrupts natural sleep patterns.
- Individual Sleep Requirements: Like shoe sizes, sleep needs vary significantly between individuals, typically ranging from 6-10 hours, with most adults requiring 7-9 hours for optimal function and sleep quality.
- The Science of Sleep Stages: Sleep consists of multiple stages including REM (dreaming) sleep and three stages of non-REM sleep, each serving different functions from memory consolidation to cellular regeneration and immune function.
- Sleep as Health Provider: Rather than viewing sleep problems as consequences of other issues, Professor Espie emphasises treating sleep as a fundamental cause of wellbeing that directly impacts physical and mental health outcomes.
- The Trust Principle for Better Sleep: Good sleep requires trusting the natural process rather than overthinking or over-engineering bedtime routines—a key component of effective cognitive behavioural therapy for insomnia treatment.
- Sleep Efficiency Concept: The proportion of time actually spent sleeping versus lying awake in bed is more important than total time in bed, with 85% efficiency being a good target for quality sleep.
Expert Sleep Tips and Practical Takeaways
- Experiment with sleep timing: Try different bedtimes and wake times to discover your natural chronotype and optimal sleep window for better rest
- Practice the “day review” technique: Spend 10 minutes each evening reviewing the day and planning tomorrow to prevent racing thoughts at bedtime—effective sleep hygiene
- Use the “stay awake” method: When unable to sleep, try to remain awake with eyes open in a relaxed state rather than forcing sleep—a natural approach to fall asleep faster
- Try the “THE” technique: Repeat the word “the” every few seconds to block intrusive thoughts—a proven form of articulatory suppression for sleep problems
- Optimise your bedroom environment: Ensure your bedroom is well-ventilated, cool, and conducive to rest as part of comprehensive sleep hygiene
- Monitor your sleep efficiency: Calculate the percentage of time spent sleeping versus time in bed to optimise your sleep window and improve sleep quality
- Get morning daylight exposure: Step outside early to help regulate your circadian rhythm and flush out residual melatonin—natural sleep science in action
- Focus on personalised sleep hygiene: Identify the one or two factors most affecting your sleep rather than trying to perfect everything—effective insomnia treatment approach
