Can deep rest really slow stress-related ageing? This episode explores the science
This preview is based on the published show notes, not a recap of the audio. Dr Elissa Epel joins to discuss how chronic stress may affect ageing, why deep rest matters for repair, and practical ideas around sleep, wearables, reframing stress, and small acts of connection.
If you’re curious about the hidden cost of everyday stress, this episode looks like a strong listen. Based on the show notes, Dr Elissa Epel brings a research-led perspective on how chronic stress may affect the immune system and ageing, alongside a more hopeful message: that certain habits may help activate repair and recovery. A central idea here is Epel’s framework of four mind states — red, yellow, green and blue — from *The Seven-Day Stress Prescription*. That suggests the conversation may be especially useful for listeners who want a simple way to notice where they are on the stress spectrum and think more clearly about what they need in the moment. The notes also point to a practical angle. Expect discussion of deep rest, evening habits that may improve sleep quality, and how wearable technology can be used more thoughtfully — including the difference between tracking day-to-day stress and spotting longer-term trends. There’s also mention of continuous glucose monitoring and what it may reveal about links between stress, sleep and metabolic health. Another appealing thread is the Big Joy Project, described here as a study involving around 20,000 people, exploring how small acts of kindness and connection can shift emotions over a week and encourage more prosocial behaviour. The episode also appears to touch on stress reframing: the idea that changing the story you tell yourself about a stressful event may influence your physiological response. If you want a preview of science-backed stress management with both biological and behavioural angles, this episode seems aimed squarely at you.
About this episode
Could the stress you barely notice be more harmful than you think? Most of us know chronic stress is bad for us, but few of us realise how deep that damage can go – or how much power we have to reverse it. In this enlightening episode, I speak with one of the world's leading stress researchers Dr Elissa Epel, a professor of psychiatry at the University of California, to explore the latest science of stress, ageing – and why deep rest may be the remedy we’re overlooking. Elissa's research as a health psychologist reveals that chronic stress can age our immune systems by as much as 10 years. But with the right habits we can activate the repair mechanisms that slow and even reverse that process. We talk about her framework of four mind states – red, yellow, green and blue – outlined in her book, The Seven-Day Stress Prescription. I find it one of the most useful tools for understanding our place on the stress spectrum at any given moment. We explore why so many of us have lost the ability to relax, the importance of deep rest for cellular repair, and the evening habits that transform the quality of your sleep. We also discuss the very latest in wearable technology and the metrics Elissa believes are worth tracking. She makes the distinction between monitoring daily stress levels and the tech that can now track longer-term trends. And she shares her experience with continuous glucose monitoring and what it revealed to her about the relationship between stress, sleep and metabolic health. I loved hearing about the Big Joy Project, Elissa’s ongoing study of around 20,000 people, finding that small, simple acts of kindness and connection can shift our emotions over the course of a week and make us more altruistic and prosocial. At a time when the world can feel divided, I think that matters enormously. Finally, we explore how changing the story you tell yourself about a stressful situation, current or past, can transform your physiological response. This reframing is something I’ve learned to do and find endlessly empowering. Our perception is not just a mental experience. It shapes our biology. Elissa is an open-hearted communicator, whose generosity comes across in everything she shares with us here. Whether you struggle with overwhelm, or you suspect you’re more stressed than you realise, I know this conversation has advice you’ll want to take on board.
