Ep210 - The Gap Between Sleep Awareness and Action — with Dr. Nunez from ResMed

In this episode, host Dr. Yishan welcomes Dr. Nunez, a leading sleep health expert whose team has conducted one of the largest global sleep surveys — spanning 30,000+ participants across 13 countries over six consecutive years. Together, they unpack a paradox at the heart of modern sleep health: why is it that even as sleep awareness grows, most people still aren't taking action to improve their sleep?Dr. Nunez shares eye-opening findings from the survey, revealing that while the majority of respondents recognize sleep's importance to long-term health, only about 26% have actually sought professional help for persistent sleep problems. The conversation dives into the real-world consequences of this awareness-action gap — from the rise of orthosomnia (an unhealthy obsession with sleep tracking data) to the dangers of relying on social media influencers for medical advice.Together, Dr. Yishan and Dr. Nunez explore what healthy sleep actually looks like beyond the numbers, why sleep apnea remains a massively underdiagnosed condition affecting roughly one billion people worldwide, and why women's sleep health — particularly during pregnancy and menopause — deserves far more attention than it currently receives. They also discuss why cognitive behavioral therapy for insomnia (CBT-I) remains underused despite being a frontline treatment, and how simple sleep hygiene fundamentals — consistent timing, a cool and dark environment, and morning sunlight — can make a bigger difference than any trending "sleep hack."If you've ever felt overwhelmed by conflicting sleep advice online, or wondered why knowing sleep matters hasn't actually helped you sleep better, this episode offers clarity, practical guidance, and the encouragement to take that next step.RESOURCESAre you so sleepy that you cannot focus?

Ep209 - Sleep, Neurotransmitters & Genetics: A Precision Medicine Approach with Kendall Stewart, MD

In this episode, Dr. Yishan sits down with Dr. Kendall Stewart — a former skull-based surgeon who has spent the past two decades pioneering a data-driven approach to functional medicine, genetics, and neuroimmune health. Together, they explore the biological roots of sleep struggles that behavioral advice alone often can't fix: neurotransmitter imbalances, genetic variants, and inflammation in the nervous system. Dr. Stewart breaks down how genes governing GABA production, melatonin receptor sensitivity, dopamine methylation, and adenosine signaling can silently undermine sleep — and how targeted nutritional support can restore the balance that makes the brain ready for rest.Dr. Stewart also shares remarkable insights from his work with thousands of patients, including children on the autism spectrum, revealing how lessons from neuroimmune research are shaping a new model of precision sleep medicine. He explains why psychological and behavioral sleep therapies work dramatically better when the brain is first supported biologically, and introduces accessible tools — including at-home genetic panels through his company Helix Revolution — that are making personalized care available without a doctor's visit. If you've ever felt that generic sleep advice just doesn't apply to you, this conversation will show you why — and what to do about it.Show Notes: deepintosleep.co/episode/ep209-kendall-stewartRESOURCESAre you so sleepy that you cannot focus?

Ep208 - What Sleep Taught Me This Year | Night Terrors, Nightmares, Sleep Apnea & Gratitude

<h2>🎙️ Deep Into Sleep — Year-End Reflection Episode</h2>As 2025 comes to an end, this special episode of Deep Into Sleep is a reflection on what a year of conversations has taught me about sleep, the brain, and the people who trust us with their nights.Rather than focusing on a single sleep disorder, this episode brings together four meaningful conversations that shaped how I now think about sleep across the lifespan—from childhood to adulthood, from behavior to biology.In this episode, we explore:<h3>🧠 Children’s Sleep Terrors</h3>Sleep terrors are often misunderstood and deeply frightening for parents. In this episode, I share key insights from a conversation with pediatric sleep expert Dr. Sarah Honaker.<h3>🌙 Nightmares Are Treatable</h3>Nightmares are common—but nightmare disorder is not something people have to live with forever. In my conversation with Dr. Courtney Worley, we discussed some myths around nightmares.One key takeaway: improving sleep often starts during the day, not at night.<h3>😴 Snoring Is Never “Just Snoring”</h3>Several conversations this year reinforced one critical message: snoring is not benign. In my discussion with sleep physician Dr. Christopher Allen, we covered why sleep apnea has been described as a “slow killer”—not dramatic, but silent. We also discuss treatment options, including CPAP, and other options, emphasizing the importance of individualized care.<h3>🧬 Precision, Not Guesswork: The Future of Sleep Care</h3>In an upcoming episode with Dr. Kendall Stewart, we explore sleep through the lens of genetics and neurochemistry. When we stop guessing and start tailoring treatment to the individual, sleep care becomes more effective—and more humane.<h3>🙏 Gratitude & Reflection</h3>This year also brought an unexpected moment of gratitude: being named “Sleep Podcast of the Year” by Dr. Chris Winter on his podcast Sleep Unplugged.I don’t take that recognition lightly. It belongs to every guest who shared their expertise, every listener who trusted this space, and every patient who reminds me why sleep education matters.If this episode helps you understand your sleep—or your child’s sleep—just a little better, then it has done its job.Thank you for going deep into sleep with me.<ol><li data-list="bullet">00:00 – Opening: Why a Year-End Reflection on Sleep</li><li data-list="bullet">01:15 – Gratitude & “Sleep Podcast of the Year” Moment</li><li data-list="bullet">02:20 – What Parents Misunderstand About Children’s Sleep Terrors</li><li data-list="bullet">05:00 – Nightmares: Common, Treatable, and Not a Life Sentence</li><li data-list="bullet">07:45 – Snoring Is Not Benign: Sleep Apnea and Brain Health</li><li data-list="bullet">11:00 – Precision, Not Guesswork: Biology + Behavior in Sleep Care</li><li data-list="bullet">13:20 – Final Reflections & Thank You</li></ol> Show Notes: <a href="https://deepintosleep.co/episode/breathing" rel="noopener noreferrer" target="_blank">deepintosleep.co/episode/breathing</a>RESOURCESAre you so sleepy that you cannot focus?
