Show Notes
If you've ever wondered whether your sleep tracker is actually accurate, or whether meditation is doing anything measurable in your brain, this episode is for you. Ariel Garten is the co-founder of Muse, the brain-sensing headband, and she's back on the show with a significant update on how the technology has evolved. The Muse Athena contains an entirely new technology called fNIRS that tracks real-time blood flow and oxygen delivery to your prefrontal cortex.
We get into why wrist-based devices like Oura and Apple Watch can only ever estimate your sleep stages - because they're guessing from heart rate and movement, not brainwave data, whereas the Muse measures deep sleep at 94% accuracy compared to a clinical sleep lab. It's Deep Sleep Boost feature uses barely-audible pink noise pulses to increase the amount of time you spend in deep, restorative slow-wave sleep. We also go into ADHD territory. Both Ariel and I are diagnosed, and we talk about what neurofeedback and meditation training can do for focus, executive function, and the near-constant urge to abandon tasks halfway through.
What you'll learn Why wrist-based sleep trackers can't accurately measure deep sleep, and how EEG-based tracking changes the picture What deep sleep actually does for your brain and body - and why it matters for memory, cognitive function, and reducing the risk of Alzheimer's How the Deep Sleep Boost feature uses tiny pink noise pulses synced to your delta waves to deepen your sleep (and why your bed partner won't even hear it) What your alpha peak frequency is, why it tends to decline with age, and how you can track and potentially maintain it through neurofeedback What fNIRS technology is and why training your prefrontal cortex to demand more oxygen could be important for long-term brain health How Muse's neurofeedback and meditation tools can support focus, attention, and executive function - and what this means if you have ADHD The full range of content in the Muse app, including over 500 guided sessions covering sleep, stress, relationships, focus, and more How the app's AI assistant, ENSO, can help you interpret your data, track trends over time, and find the right tools for your goals Resources mentioned

Why do some people go through trauma and come out the other side better for it?
When a crisis turns your world upside down, what do you do? Last week we talked about how to make a big decision. This week I'm talking about when the decision gets made for you. You lose the job or the relationship or the house, or you get a diagnosis you didn't see coming, and suddenly the change you never asked for is here and completely out of your control.
Stuck on a big life decision? Let’s talk about the psychology of decision making. Whether you're weighing up a job, relationship, starting a business or buying a house, big decisions have a way of keeping you stuck on the fence. In this episode I'm explaining why your pros and cons list is no help, and how your predictions of how happy you'll be depending on what you decide are wildly unreliable, and why we usually default to the status quo even if it makes us miserable rather than take a risk on the unknown.
It's nice to feel content, peaceful and satisfied with life. But how long do you let yourself feel any of those things before you get twitchy?
If you’re feeling a little bored and uninspired, I get it. I noticed recently that after 9 years of podcasting, ideas were not flowing and creativity felt like a chore. (This is normal of course.) But after spending two days out of the office at The Podcast Show last week, I’ve discovered renewed enthusiasm.
