| 6/22/26 |  #141 - The Daylight Mistake | Matt illuminates sunlight’s biological impact beyond Vitamin D as he reveals that our eyes contain a hidden daylight circuit wired directly to the brain. These "sky detectors" use bright outdoor light to instantly boost alertness, sharpen attention, and trigger a morning cortisol surge. Lacking this intense daylight indoors leaves us sluggish and out of sync. He also breaks down the lifelong benefits of light exposure, from treating depression to preventing childhood myopia, and shares a ze... | 26m 07s | ||||||
| 6/15/26 |  #140 - Tired but Wired | Exploring the "tired but wired" state where exhaustion meets an overactive alerting system, Matt explains that insomnia is often a disorder of hyperarousal rather than a lack of sleep drive. Using metabolic data and brain activity, he shows how an internal "accelerator" remains pressed despite an empty fuel tank, causing the body and brain to stay alert when they should be resting. Matt shares evidence-based CBT-I tools to break this cycle, including the "cognitive shuffle" and specific image... | 29m 04s | ||||||

| 2/16/26 |  #124 - Acting Out Dreams | Matt delves into the world of REM Sleep Behavior Disorder (RBD), a condition at the frontiers of sleep science. Normally, the brain dreams while atonia paralyzes the body in a neural magic act that is managed by brainstem nuclei activating inhibitory "brakes" in the spinal cord. When this circuit fails, the motor system remains active, enacting nightmares in real-time. RBD is hazardous - 10% of patients sustain injuries requiring medical intervention or hospitalization. It is a prodromal synu... | 28m 00s | ||||||
| 2/9/26 |  Ask Me Anything Part 25: Sleep Talking, Long Covid, CBD/CBN, and Bedroom Environment | Matt and Dr. Eti Ben Simon begin their latest AMA by exploring somniloquy as fragmented noise within Stage 2 NREM sleep. They distinguish these vocalizations from REM Sleep Behavior Disorder, where the brain’s paralysis mechanism fails. The pair also examines how Long Covid triggers chronic sleep fragmentation in half of all patients. This disruption is tethered to systemic inflammation and elevated C-reactive protein. The hosts find sparse evidence for CBD and CBN, noting a pattern of pharma... | 40m 01s | ||||||
| 2/2/26 |  #123 - Sleep & the Microbiome | Matt explores a revolutionary shift in sleep science, identifying the gut microbiome as a secondary control center for rest. He elucidates the bidirectional gut-brain axis, where the Vagus nerve connects trillions of microorganisms to the brainstem, and details how bacterial metabolites, specifically the short-chain fatty acid butyrate, trigger critical BDNF-TrkB signaling to orchestrate deep NREM sleep. Using Parkinson’s disease as a model, he demonstrates how gut dysbiosis undermines sleep ... | 29m 24s | ||||||
| 1/26/26 |  #122 - Exercise vs. Insomnia | Examining the $107B burden of insomnia and its link to a 45% increase in cardiovascular risk, Matt dissects a landmark study of 1,348 participants proving that movement is a potent clinical tool. He also explains how yoga adds nearly two hours of sleep by boosting GABAergic activity, while Tai Chi provides sustained benefits for up to two years. Our host details how exercise facilitates the core temperature drop necessary for consciousness to power down. Matt discusses how movement increases ... | 30m 26s | ||||||
| 1/19/26 |  #121 - A Practical Guide To Insomnia | Matt delves into insomnia, defining it as a persistent struggle to sleep despite having the opportunity. He presents "Cognitive Behavioral Therapy for Insomnia" (CBTI) as the scientifically validated gold standard, and details the five pillars: stimulus control to rebuild the bed-sleep association, time-in-bed restriction to boost efficiency, sleep hygiene, cognitive restructuring, and relaxation. These strategies retrain the brain to treat the bed as a sanctuary, deactivating the psychologic... | 23m 52s | ||||||
| 1/12/26 |  Ask Me Anything Part 24: Tinnitus, SAD, Sleep Divorce, and Vaccines | Matt and Dr. Eti Ben Simon return with another AMA episode where they answer such listener questions as how sleep loss amplifies tinnitus and how Seasonal Affective Disorder impacts circadian rhythm. They also reveal that sleep restriction slashes vaccine-induced antibody production by 50%, and highlight deep NREM sleep as the vital soil for immunological memory. The hosts go on to analyze somniloquy, address long COVID’s inflammatory sleep fragmentation, and critique the fading efficacy of C... | 49m 38s | ||||||
| 1/5/26 |  #120 - How Sleep Deprivation Hijacks Your Genetic Code | Putting sleep deprivation under the microscope yet again, Matt explores our "genetic workforce" of 20,000 genes operating on a precise 24-hour cycle. He details 2013 research showing that just one week of six-hour nights alters 711 genes - three percent of the human genome. This shift disrupts the circadian clock’s coordination, moving the body away from essential repair toward cellular stress and inflammatory markers. Matt also examines the tissue-specific damage of sleep loss, explaining ho... | 20m 09s | ||||||
