Dr. William “Bill” Jagust, renowned expert in brain science and Alzheimer’s research - and one of the reasons Matt chose to move to UC Berkeley - joins our host today for an in-depth discussion on aging, cognitive decline, and the critical role of neuroimaging, with some sleep talk woven in as well. Dr. Jagust shares groundbreaking insights into how PET scans can detect amyloid and tau proteins in the brain—two key contributors to Alzheimer’s disease—years before symptoms emerge. Together with Matt he goes on to explore the connection between these proteins and brain aging, highlighting the power of biomarkers and advanced imaging in tracking the disease's progression. Our esteemed guest also emphasizes that early detection and intervention are crucial in slowing Alzheimer's progression, but warns that once neurons are damaged, the brain has minimal capacity to repair itself. He further discusses lifestyle choices such as exercise, diet, and sleep, which can lower the risk of cognitive decline, and dives into emerging research on genetic factors like the APOE4 gene. The episode concludes with a hopeful outlook on the future of Alzheimer’s research, offering insights into potential preventive treatments.

In this latest AMA episode, Matt and Eti are back to tackle listener questions about naps and sleepwalking this time around. They begin by delving into the intricacies of power naps and their impact on brain function and sleep health, and go on to discuss the optimal timing and duration for naps, emphasizing that a balance between benefits and drawbacks is crucial.
Shorter naps of 10-20 minutes are highlighted for their ability to boost alertness and focus with minimal sleep inertia. Conversely, longer naps offer more substantial cognitive benefits but come with the risk of grogginess upon waking, particularly due to the transition from deeper stages of non-REM sleep. The discussion also explores the origins of "power naps," touching on research by NASA and the FAA that underscores the value of napping in high-stakes environments like space missions and long-haul flights.
Addressing sleepwalking, a common sleep disorder in children, our hosts offer practical advice on managing it safely, reassuring parents that sleepwalking often decreases with age and that maintaining a regular sleep schedule can help mitigate episodes. They also provide on how to deal with a child while they are in the act of sleepwalking.
The episode concludes with a thoughtful reflection on the importance of sleep for overall health and well-being, reinforcing the critical role that sleep plays in our lives.

Dr. Wendy Troxel returns to the podcast today to discuss the significant impact of sleep on relationships and mental health with Matt. Offering actionable strategies for couples facing inevitable sleep disruptions, Dr. Troxel emphasizes the importance of communication, suggesting that couples anticipate sleep challenges, share responsibilities, and use tools like the "slangry" label to recognize and manage sleep-deprived behaviors. She also highlights the importance of timing conversations and creating positive shared experiences, even when sleep-deprived, to maintain relationship quality.
Dr. Troxel further debunks common myths about sleep and relationships, including the misconception that sleeping apart signifies a troubled relationship or that snoring is merely a nuisance. She stresses the need for couples to understand and respect their chronotypes—whether they are early birds or night owls—and to find harmonious solutions that accommodate their different sleep patterns. By prioritizing sleep and maintaining open communication, couples can enhance their relationship, reduce conflict, and improve overall well-being - sleep is not just a personal health issue but a critical factor in sustaining healthy, connected relationships.

This week, Matt shines his spotlight on the intriguing topic of melatonin use for individuals living with autism spectrum disorder (ASD). While melatonin has been discussed in previous episodes in relation to sleep enhancement and antioxidant properties, today's focus is on a recent meta-analysis that examines its effectiveness in treating sleep disorders specifically in those with ASD. This deep dive is prompted by new data and the pervasive sleep challenges faced by individuals with autism, making it a timely and important discussion.
Matt explores the nuanced mechanisms and varied sleep problems associated with ASD, emphasizing the importance of personalized treatment plans. The episode highlights how melatonin can potentially aid in increasing total sleep time and improving sleep onset latency, though it shows variable results in sleep efficiency. Listeners are reminded that while melatonin offers promising possibilities, it is not a one-size-fits-all solution and must be considered carefully, particularly in terms of dosage and individual conditions. Additionally, the discussion includes potential adverse effects and the importance of medical supervision when using melatonin as a treatment for children with ASD.

In yet another informative and entertaining AMA episode, Matt and Doctor Eti Ben-Simon delve into the variety of sleep-related questions uppermost in listeners’ minds . Matt begins by explaining that THC, the main psychoactive component in cannabis, can help individuals fall asleep initially but disrupts sleep patterns and circadian rhythms with chronic use. This can lead to increased brain temperature, tolerance, dependence, and decreased REM sleep, impacting emotional regulation and overall health. Emerging data on cannabis's potential benefits for sleep apnea are inconclusive.
Matt and Eti also discuss white noise's impact on sleep, particularly in noisy environments, as studies show it can help people fall asleep faster and improve sleep efficiency, though results vary. On melatonin supplementation, they offer a vast amount of information, including a caution against overuse due to dosage inconsistencies and potential long-term effects. Our duo goes on to address the concept of "enough sleep," noting the average person needs 7-8 hours, but optimal sleep varies. Excessive sleep often indicates poor quality and health issues, potentially increasing mortality risk. Wrapping up, this episode emphasizes understanding sleep aids, their effects on sleep quality, and achieving optimal sleep health.

The Science of Shared Sleep: Dr. Wendy Troxel on Bedtime and Relationships
This week, Matt is joined by Dr. Wendy Troxel the celebrated sleep and behavioral scientist whose book, Sharing the Covers: Every Couple's Guide to Better Sleep, highlights the significant impact of sleep on relationships. Revealing that 61% of adults sleep with a partner, Dr. Troxel emphasizes the often-overlooked social aspect of sleep and its implications for couple dynamics. As she notes, sleep arrangements have historically varied widely, from communal sleeping in the Middle Ages to separate beds in the Victorian era for hygiene and status reasons. These changing practices reflect evolving societal norms and beliefs about intimacy and health.
Troxel also explores how modern sleep disruptions, such as snoring, differing sleep preferences, and work schedules, can affect relationships. She stresses the importance of open communication and mutual understanding of chronotypes—whether one is a morning lark or a night owl—in managing sleep compatibility. Recognizing and addressing these issues can lead to better sleep quality and, consequently, a healthier relationship. As you will hear, Dr. Troxel's research underscores that there's no one-size-fits-all solution, and advocates for personalized strategies to improve both sleep and relationship health.

Matt continues his series on the impact of cannabis, THC, and CBD upon sleep this week with an examination into the intricacies of cannabidiol (CBD), which, unlike its psychoactive counterpart THC, does not induce a high but is recognized for its potential therapeutic effects. While studies suggest that CBD may aid in alleviating anxiety, movement disorders, pain, and addiction, in this episode, our host focuses on exploring CBD's potential influence on sleep quality while examining its biochemistry and neurobiology.
Matt explains that CBD modulates the body's endocannabinoid system without directly binding to cannabinoid receptors like CB1 and CB2, which THC targets. Instead, CBD enhances the activity of natural endocannabinoids, extending their effectiveness. This modulation can promote sleep by increasing deep non-REM sleep, as demonstrated in both animal and human studies. Despite these promising results, Matt emphasizes that the effects of CBD on sleep are complex and dose-dependent, with higher doses showing potential benefits.

In this week’s intriguing episode, Matt delves into the topic of precognitive dreams, exploring the idea that some people can predict future events through their dreams. He explains that while this concept might seem appealing, it is actually a result of statistical chance. With around 8 billion people in the world each having multiple dreams per night, the sheer number of dreams increases the likelihood of coincidental matches between dreams and real-life events.
Matt also discusses a groundbreaking study published in the highly respected journal, Nature, which reveals a logical and scientific aspect of future prediction in dreams. The study found that during REM sleep, neurons in the hippocampus not only replay past memories but also simulate and predict future events. This prediction process occurs through sharp wave ripple events, suggesting that our brains use sleep to enhance cognitive function and prepare for future scenarios. This understanding of how sleep aids in memory and future planning highlights the remarkable and scientifically fascinating capabilities of the brain during sleep. Join Matt here today and discover the profound, scientifically grounded ways our brains use sleep to prepare us for the future.

In this 7th installment of their AMA series, Matt Walker and Dr. Eti Ben Simon dive into strategies for improving deep non-REM sleep. They highlight the benefits of vigorous exercise, citing a study by Kaspar Vogt that shows how exercise enhances the quality and stability of deep sleep. Additionally, they discuss how temperature manipulations, like using high heat capacity mattresses, can also improve sleep quality. Interesting insights include findings that intense exercise can improve deep sleep across various age groups, with significant benefits noted in older adults and children.
The episode also touches on the impact of alcohol, noting that it can be extremely disruptive to sleep. They also go on to explain how stress and anxiety can affect deep sleep by activating the fight-or-flight system and increasing cortisol levels. Our duo discusses various techniques for managing anxiety, such as cognitive behavioral therapy (CBT), mindfulness meditation, exercise, deep breathing, and progressive muscle relaxation, all of which can significantly reduce anxiety levels and improve sleep quality. Their conversation finishes up by addressing the potential benefits of saunas and hot springs in enhancing sleep, and underscoring the importance of a consistent bedtime routine.

Matt continues his exploration into the intricate link between cannabis and sleep, focusing on THC in this second installment, beginning with a reminder to listeners of the historical insights from doctors like O'Shaughnessy and Clendinning in the 1800s regarding cannabis's sleep-inducing effects. He shifts to how THC affects sleep today, noting that while it initially reduces sleep onset time and early night awakenings, chronic use worsens sleep quality, leading to frequent disruptions, especially in the second half of the night due to lower "sleep pressure."
Matt then dives into THC's impact on REM sleep, crucial for memory and emotional regulation. He details how THC reduces REM sleep quantity and quality, affecting cognitive and emotional stability the next day. He also touches on broader health risks associated with reduced REM sleep, including increased mortality risks, as well as the sleep issues associated with quitting THC. Acknowledging full well that he has “no business telling anyone what to do with their life or how to live their life,” Matt's discussion here today simply provides the scientific data behind the pros and cons involved in the THC-sleep space, laying a solid foundation upon which listeners can make their own choices.

Matt introduces his series examining the complex relationship between sleep and cannabis, exploring both the historical context and contemporary scientific perspectives. The narrative begins with Dr. W.B. O'Shaughnessy's canine experiments in 1849, tracing the evolution to the foundational work on cannabis for sleep conducted by Drs. Clendinning and Bradbury. Despite anecdotal reports suggesting cannabis enhances sleep, the scenario is complicated by factors such as regulatory constraints, variable product quality, and the potential long-term health implications of cannabis usage.
In discussing the impact of cannabis on sleep, Matt elucidates the interactions among THC, CBD, and the endocannabinoid system. Initial benefits may include improved sleep onset and efficiency, but chronic use is often associated with negative outcomes such as increased nocturnal awakenings and reduced sleep quality in the latter half of the night. Additionally, Matt explores the challenges associated with discontinuing cannabis use, including the risk of THC dependency for sleep induction, highlighting the necessity for evidence-based approaches and individualized decision-making in using cannabis as a sleep aid.
Matt's analysis extends to the global context of cannabis consumption, advocating for well-informed choices amidst its growing popularity and the dynamic landscape of scientific research.

This week, Matt dives deep into the complexities of REM Sleep Behavior Disorder (RBD), a condition where individuals physically act out their dreams due to the absence of normal muscle paralysis during REM sleep. He meticulously breaks down the mechanisms of normal REM sleep, where the brainstem induces muscle atonia to prevent dream enactment, contrasting it with the failure of this system in RBD cases.
Further expanding on the topic, Matt explores the etiology, diagnosis, treatment options, and prognosis of REM Sleep Behavior Disorder. He outlines the primary, drug-induced, and secondary types of RBD, with a focus on the idiopathic category, linking its occurrence to neurodegeneration and the accumulation of alpha-synuclein protein in the brainstem. Treatment strategies include lifestyle adjustments and pharmacological interventions like melatonin and clonazepam, aiming to reduce injury risks.

Eti is back for another AMA episode with Matt to answer questions that have been submitted over the last little while. Today’s installment dives into a number of topics including the intricate relationship between sleep and pregnancy, exploring how sleep disturbances impact pregnant women and the postnatal period. Additionally, the hormone prolactin, essential for milk production, is highlighted for its sleep-promoting benefits during the postnatal phase, illustrating nature's intricate balance between nurturing new life and ensuring the mother's rest.
Their discussion also touches on whether pregnancy sleep disturbances are all part of preparing mom for baby’s arrival which, of course, can further disrupt schedules, citing the very few biological exceptions where sleep is actually sacrificed for survival. Our experts also undertake a light-hearted exploration of "eye gunk" (rheum), demystifying its composition and reassurance that its presence is a normal part of sleep hygiene rather than an indicator of sleep quality. They finish up by responding to a question regarding the connection between sex, masturbation, and sleep, which you absolutely do not want to miss.
Tune in today, and don’t forget to send in any sleep questions you may have - Matt and Eti might just answer them in a future episode!

In today's podcast episode, Matt welcomes back Dr. Michael Gradisar to delve into the evolving understanding of screens and sleep. Initially holding the belief in the detrimental effect of screen light on sleep, Matt finds this notion challenged by Dr. Gradisar's research, which emphasizes a more nuanced perspective. Their discussion highlights the shift from simplistic concerns about screen use to acknowledging the multifaceted influences on sleep, including content and individual differences.
Dr. Gradisar's experiments, such as exposure to violent video games and bedtime displacement monitoring, emphasize the complexity of the relationship between technology use and sleep, stressing the need for personalized approaches to addressing sleep issues. His dialogue with Matt underscores the importance of scientific inquiry in challenging and refining commonly held beliefs about technology and sleep, advocating for a nuanced understanding that considers individual behaviors and differences. Furthermore, both speakers encourage researchers to engage with industry and the public, translating findings into practical advice for improving sleep hygiene and promoting healthier sleep practices.
