    All-Star Panel on Wearable Sleep Trackers
    2024/06/17
    In this episode:Jesse Cook, Cathy Goldstein and Olivia Walch grade their own sleep Why the answer to “Do most people need granular sleep-stage data?” is no Clinical sleep definitions versus consumer wearable outputs Why an EEG headband has an advantage over a motion-only tracker — but still is not a polysomnogram Sleep sensitivity, wake specificity and the trap hidden inside a 90% accuracy claim Why REM and deep-sleep staging are harder than basic sleep/wake detection What quiet wakefulness does to wrist-based algorithms Why actionability can matter more than precision Orthosomnia and the risks of sleep perfectionism Why one bad nightly score should not become a crisis How tracker validation changes across populations and sleep disorders Why proprietary algorithm updates can age a validation study overnight The case for access to raw sensor data and shared validation datasets What the World Sleep Society and National Sleep Foundation now recommend for consumer sleep technology Why healthy sleep includes more than duration Sleep regularity, rhythmicity, continuity, timing and daytime functioning Why a low consumer deep-sleep score cannot be translated directly into dementia risk What glymphatic research actually says about sleep stages Neil’s Dreem 2 data and which numbers catch the panel’s attention Temperature, awakenings and using wearable trends to test practical hypotheses Why mainstream trackers may be enough for most behavioral goals The importance of comfort, adherence and battery life FTC and FDA oversight of consumer health and wellness claims What seven-to-nine-hour recommendations actually mean Why trying too hard to sleep can become part of the problemAbout Jesse CookJesse Cook, PhD, is a sleep researcher and clinical psychologist at the University of Wisconsin–Madison. His work has examined sleep and mental health, hypersomnolence, athletes and the performance of wearable sleep technology. Cook previously joined The Snooze Button for a full episode devoted to the question of who validates the trackers themselves.About Dr. Cathy GoldsteinDr. Cathy Goldstein is a Clinical Professor of Neurology at the University of Michigan and a sleep physician whose work includes consumer and clinical sleep technology, circadian rhythm disorders and the use of wearable data. Her research has included efforts to improve and openly evaluate algorithms used to characterize sleep from wearable sensors.About Dr. Olivia WalchOlivia Walch, PhD, is a mathematician and circadian scientist whose research focuses on biological rhythms, sleep timing and mathematical models of the human circadian system. She is affiliated with the University of Michigan Center for Sleep Science and is CEO of Arcascope, which develops circadian-health technology.Archive update, 2026: At the time of this conversation, Walch’s book was still on the way. Sleep Groove: Why Your Body's Clock Is So Messed Up and What To Do About It was published January 28, 2025 by Andrews McMeel. The book uses comics and circadian science to explain why sleep timing goes wrong and what people can realistically do about it.MENTIONEDJesse Cook — University of Wisconsin–Madison Cathy Goldstein — University of Michigan Medical School University of Michigan Center for Sleep Science faculty Olivia Walch and Arcascope Sleep Groove: Why Your Body's Clock Is So Messed Up and What To Do About It Selecting a sleep tracker: EEG-based, multisensor and actigraphy-only devices 2025 validation of six commercial wrist-worn sleep trackers 2026 rapid review: real-world use of consumer sleep devices World Sleep Society recommendations for wearable consumer health trackers that monitor sleep National Sleep Foundation position statement on consumer sleep technology Screening for orthosomnia and sleep-related preoccupation U.S. survey of consumer sleep technology use, trust and sleep-related worry Which sleep health characteristics predict all-cause mortality in older men?

    Two Rock Stars Talk About Sleep
    2023/07/24
    In this episodeWhy Lawrence Gowan says he often sleeps better on a moving tour bus than almost anywhere else How sleep differs among members of Styx on the road Why trust in the tour-bus driver matters to Gowan's ability to switch off How touring fitness changes when musicians move through their 40s, 50s and beyond Gowan's transition from hockey to weights, yoga, walking and cycling Why performing more than 100 shows a year is physical work in its own right How Gowan thinks about protecting and developing his singing voice with age The deliberately classic progressive-rock sound of Crash of the Crown Queen, Genesis, Yes, Jethro Tull, The Who, vintage keyboards and analog gear Why Styx still isn't in the Rock & Roll Hall of Fame Gowan's practical sleep habits: schedule, less phone time and writing down late-night worries The autobiographical memory exercise he uses when awake at four in the morning Why musicians can obsess for hours over a mistake the audience never noticed Dr. Mark Boulos on restless legs syndrome, periodic limb movements and augmentation Why suddenly worsening RLS should trigger a review of iron, sleep, medications and other conditions Neil's experience of worsening movement symptoms after a mental-health medication change Why vortioxetine/Trintellix should not be described as an SNRI What current evidence does — and does not — say about antidepressants and RLS How current RLS treatment guidance has shifted away from routine dopamine agonists such as pramipexole Why bupropion as an antidepressant option is different from bupropion as an RLS treatment The danger of crowdsourced medication advice when nobody knows the full clinical pictureAbout Lawrence GowanLawrence Gowan is a Canadian singer, songwriter and keyboardist whose solo career produced hits including A Criminal Mind, Strange Animal and Moonlight Desires. He joined Styx in 1999 and remains the band's keyboardist and one of its principal vocalists and songwriters.
