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. #feelbetterlivemore Find out more about Dr Epel: Website https://www.elissaepel.com/ Instagram https://www.instagram.com/elissa.epel/?hl=en Twitter https://twitter.com/Dr_Epel Facebook https://www.facebook.com/TelomereEffect YouTube https://www.youtube.com/channel/UCirLcEfBEaIynGDwZaJvdaQ Dr Epel’s books: The Telomere Effect:The New Science of Living Younger UK https://amzn.to/4aceSFv US https://amzn.to/4eXgiq0 The Stress Prescription: Seven Days to More Joy and Ease UK https://amzn.to/4gz9L68 US https://amzn.to/4oEY6VD #feelbetterlivemore #feelbetterlivemorepodcast ------- Order MAKE CHANGE THAT LASTS.

WHAT IT’S REALLY ABOUT

Chronic stress accelerates cellular aging; deep rest and joy reverse

  1. Chronic stress is linked to shorter telomeres—a marker of cellular aging—equating to roughly a decade of additional immune-system aging in early studies, yet lifestyle shifts can activate telomerase and other repair pathways.
  2. Stress is not inherently harmful: healthy physiology features low baseline arousal, strong acute responses when needed, and rapid recovery, while chronic stress locks people into persistent activation and blunts flexibility.
  3. Epel’s “mind states” framework (red/yellow/green/blue) helps people identify whether they’re in acute stress, subtle chronic cognitive load, relaxation, or deep rest—the last of which is increasingly rare but most biologically restorative.
  4. Pre-sleep downshifting is a high-leverage intervention because nervous-system arousal during sleep can remain elevated even with adequate sleep duration, reducing metabolic, hormonal, and repair benefits of the night.
  5. Research discussed includes mindful-eating training in pregnancy improving maternal glucose and mood with long-lasting benefits and apparent stress-resilience effects in offspring, plus “micro-acts of joy” that build positive affect and prosocial behavior over a week.

IDEAS WORTH REMEMBERING

5 ideas

Telomere length reflects cumulative stress wear-and-tear—but it’s dynamic.

Epel describes telomeres as protective chromosome ends that shorten with age and with chronic physiological stress; importantly, restorative behaviors can increase telomerase activity and support cellular repair over time.

The goal isn’t “no stress,” it’s fast recovery and flexible shifting.

Healthy stress responding looks like low baseline arousal, high peaks when demanded, and a quick shutoff; chronic stress reduces the ability to downshift and can even blunt normal acute stress responsiveness.

Most people live in “yellow mind” (invisible cognitive load) and mistake it for normal.

Yellow mind is moderate, pervasive arousal that becomes a default; building “stress fitness” means moving out of yellow via either true recovery (green/blue) or bounded acute stressors like exercise.

Deep rest (blue mind) is qualitatively different from relaxation—and often missing.

Blue mind emphasizes passive, safe, letting-go states (e.g., yoga nidra, lying-down visualization, restful music) that switch on repair processes; Epel argues modern grind culture has squeezed these states out.

Pre-sleep state strongly determines whether sleep is restorative.

Even if someone falls asleep quickly, their nervous system may remain vigilant during the night; downshifting before bed supports parasympathetic dominance, deeper sleep physiology, metabolic reset, and anabolic repair hormones.

WORDS WORTH SAVING

5 quotes

We statistically can say with confidence shorter telomeres predicts more likelihood of early disease, early mortality, slower wound healing.

Dr. Elissa Epel

Any time in life, any day, we can start to reverse damage and boost all of the restorative enzymes and processes in the cell and lengthen our telomeres.

Dr. Elissa Epel

I think it's the hidden epidemic, the, the disappearance of true relaxation.

Dr. Elissa Epel

The beauty of feelings of stress is that they are absolutely malleable, and we can change our physiological stress as well as our emotional stress within five minutes.

Dr. Elissa Epel

If we're ripping ourselves off of relaxation and we're not getting deep rest, we are aging faster.
