  • #99 - Insomnia in 7 Days with Dr. Aric Prather
    Jun 2 2025

    Sleep expert Dr. Aric Prather joins Matt today for a fascinating discussion about insomnia's frustrating reality: trying to force sleep backfires; sleep arrives naturally. Dr. Prather highlights a surprising starting point: forget focusing on bedtime, prioritize a consistent wake-up time, even weekends. Noting that this anchors your internal clock and builds essential sleep pressure (the 'balloon'), he also cautions that sleeping in after a bad night disrupts this cycle.

    After touching on societal factors impacting sleep, the conversation shifts to managing the mental side—the stress and anxiety creating that 'tired but wired' state. Dr. Prather shares practical techniques: daytime micro-breaks, breathing exercises, and scheduling worry time to keep thoughts from hijacking the night. Listeners learn how the bedroom can become a trigger for wakefulness and how stimulus control (getting out of bed when not sleeping) breaks that association. Finally, they cover Time-in-Bed Restriction: deliberately spending less time in bed can paradoxically consolidate sleep by intensifying sleep drive, building confidence. This episode offers tools not for nightly success, but for improving sleep on average and reducing panic over occasional bad nights.

  • #98 - Weighted Blankets
    May 19 2025

    Matt delves into the science of weighted blankets for sleep improvement in this week’s episode. These heavy covers (10-40 lbs) utilize Deep Pressure Stimulation (DPS), a concept originating from Dr. Temple Grandin's 1960s work. DPS is theorized to shift the nervous system from "fight-or-flight" to a calmer parasympathetic state by potentially increasing serotonin and activating brain regions involved in emotional regulation, like the insular cortex, thereby fostering a state conducive to sleep.

    Matt describes research whose highlights include a 2020 study where 42% of insomnia patients achieved remission with weighted blankets, and a 2021 study that showed healthy adults experienced increased deep sleep and less restlessness. Benefits are also noted for children with ADHD. Proposed mechanisms extend to reduced awakenings and anxiety. While studies show promise for specific groups, larger, objective trials are still needed. Weighted blankets (around 10% body weight) are best viewed as a potential aid alongside good sleep hygiene.

I am very much enjoying learning more about sleep, and the many ways it can affect us! Thank you for this informative and enjoyable podcast!

Fascinating and well-delivered information!

As I write this review, there are 26 podcasts in the series and they have all been enjoyable, 10-20 minutes in length, science-based, free from profanity, and delivered in a calm, easily understandable manner. Laypersons and scientists alike will enjoy the useful information, and Dr. Walker's passion for communicating it is contagious. He is a gifted educator. Each podcast leaves one feeling empowered with the knowledge of how to support one's own sleep, eager for more episodes, and in a happier mood from his sheer exuberance about the topic. 5 stars!

Updated review: 45 podcasts in and still well worth tuning in. I look forward to each episode (released every 2 weeks), and I hope Dr. Walker continues to share his knowledge and enthusiasm about sleep for a long time coming :) 5 stars!

Congratulations to Dr. Walker on reaching the 50-podcasts milestone--particularly as they remain relevant, educational, and entertaining. I particularly enjoy the new format, called "Hot Off the Press", in which current research findings on a topic are discussed in a manner we all can understand and enjoy. I can honestly say that I look forward to each new episode, even after 2 years of listening :)

Updated review: 67 podcasts along and I still look forward to each new one to learn more about sleep. I enjoy the single-topic ones and the guest/Ask-Me-Anything ones. It remains positive and science-based format, which is a refreshing change from much of what is out on the Internet and airwaves nowadays. I look forward to learning more in the coming episodes, and I appreciate all the hard work going into them.

Refreshingly positive and science-based
