The science of sleep | Heather Darwall-Smith | #004 Mastering Change

When we think of sleep disorders, we tend to imagine insomnia or sleep apnoea. But did you know there are over 80 different sleep disorders? This week, we spoke to sleep expert and UKCP-registered psychotherapist Heather Darwall-Smith on the complexities of sleep. Heather, author of The Science of Sleep, holds an MA in Core Process Therapy and has studied sleep medicine and cognitive behavioral therapy at the University of Oxford.  One of the most powerful takeaways from our conversation was the toxicity of sleep-shaming culture. As Heather highlights, there’s a misleading belief that a perfect sleep routine exists and that everyone should strive for it. In reality, sleep is deeply personal and influenced by biology, culture and lifestyle. It’s about what feels right for you. We discussHow we need to feel safe in order to sleep How traumatic experiences disrupt natural sleep cycle and why feeling safe is key to restorative rest The rise of sleep disorders (such as sleep apnoea) How sleep disorders effect couples and their relationships The unregulated sleep supplement market and what to be wary of Heather’s passion for sleep medicine and her compassionate, science-backed approach make her an invaluable voice in this space. Her insights were both reassuring and thought-provoking – have a listen for yourself! Moment of Care: This episode discusses sensitive episodes related to trauma, mental health and potential distressing experiences.
