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.  <b>Ariel Garten</b> 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.<br /><br />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.<br /><b><br />What you'll learn</b><br /><ul><li>Why wrist-based sleep trackers can't accurately measure deep sleep, and how EEG-based tracking changes the picture</li><li>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</li><li>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)</li><li>What your alpha peak frequency is, why it tends to decline with age, and how you can track and potentially maintain it through neurofeedback</li><li>What fNIRS technology is and why training your prefrontal cortex to demand more oxygen could be important for long-term brain health</li><li>How Muse's neurofeedback and meditation tools can support focus, attention, and executive function - and what this means if you have ADHD</li><li>The full range of content in the Muse app, including over 500 guided sessions covering sleep, stress, relationships, focus, and more</li><li>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</li></ul><b>Resources mentioned</b><br /><b></b><br /><b>Muse headband: </b><br /><a href="https://choosemuse.com/cassdunn" target="_blank" rel="noreferrer noopener">www.choosemuse.com/</a><br />(enter code cassdunn at checkout for 15% off)<br /><b></b><br /><b>Previous episode with Ariel Garten (2019) </b><br /><a href="https://www.crappytohappypod.com/wearable-technology-for-your-brain-with-ariel-garten/" target="_blank" rel="noreferrer noopener">https://www.crappytohappypod.com/wearable-technology-for-your-brain-with-ariel-garten/</a><br /><br /><b>Beyond Confident 2.0 for Solopreneurs &amp; Service Providers </b><br /><b>Open for enrolment NOW.</b><br /><b></b><br />Transform self-doubt &amp; self-sabotage, rewire your nervous system for success, and do the inner healing work, while being supported to create a streamlined, profitable business that supports your lifestyle.<br /><br /><b><a href="https://www.cassdunn.com/bc-call" target="_blank" rel="noreferrer noopener">www.cassdunn.com/bc2</a></b><br /><br /><b>Connect with Cass:</b><br /><b></b><a href="https://www.cassdunn.com/" target="_blank" rel="noreferrer noopener">www.cassdunn.com</a><br /><a href="https://www.instagram.com/cassdunn_xo" target="_blank" rel="noreferrer noopener">www.instagram.com/cassdunn_xo</a><br /><br /><b>Contact Crappy to Happy:</b><br /><br />Email: [email protected]<br /><a href="https://www.crappytohappypod.com" target="_blank" rel="noreferrer noopener">www.crappytohappypod.com</a><br /><a href="https://www.instagram.com/crappytohappypod" target="_blank" rel="noreferrer noopener">www.instagram.com/crappytohappypod</a><br /><b></b><b></b><p><strong>Connect with Cass:</strong></p><p><a href="https://www.cassdunn.com/" rel="noopener noreferrer" target="_blank">www.cassdunn.com</a></p><p><a href="https://www.instagram.com/cassdunn_xo" rel="noopener noreferrer" target="_blank">www.instagram.com/cassdunn_xo</a></p><br><p><strong>Contact Crappy to Happy:</strong></p><br><p>Email: [email protected]</p><p><a href="https://www.crappytohappypod.com" rel="noopener noreferrer" target="_blank">www.crappytohappypod.com</a></p><p><a href="https://www.instagram.com/crappytohappypod" rel="noopener noreferrer" target="_blank">www.instagram.com/crappytohappypod</a></p><hr><p style='color:grey; font-size:0.75em;'> Hosted on Acast.
