Join Matt today as he explores the fascinating intersection of sleep, metabolism, and weight management, delving into the science of dual orexin receptor antagonists (DORAs). This episode dissects a groundbreaking study on suvorexant (Belsomra), an FDA-approved insomnia medication, and its potential to enhance fat burning during sleep. Matt unpacks the role of orexin, a neuropeptide crucial for wakefulness, and explains how DORAs work by targeting orexin receptors to promote natural sleep.
This preliminary research, conducted on healthy young men, reveals suvorexant's intriguing ability to not only improve sleep quality, but also increase fat oxidation while preserving muscle mass. While these initial findings are promising, Matt emphasizes the importance of cautious optimism and the need for further research in more diverse groups. He explores the implications for weight management and metabolic health, highlighting the potential of suvorexant as a novel approach to weight loss. However, Matt underscores that a holistic approach, including diet, exercise, and good sleep hygiene, remains essential for long-term success. Tune in today to gain valuable insights into the complex relationship between sleep and metabolism, and how scientific advancements may pave the way for innovative solutions in weight management.

Matt dives deep into the science of memory with renowned neuroscientist Dr. Charan Ranganath, author of Why We Remember: Unlocking Memory's Power to Hold On to What Matters in today’s episode. Together, they explore the complex relationship between memory and the brain, touching on the roles of emotional significance, context, and even neuromodulators like dopamine in helping our brains decide which memories to retain and which to discard.
Dr. Ranganath shares his unique journey into memory research and insights from his pioneering work at the Dynamic Memory Lab at UC Davis, where his studies have reshaped our understanding of human memory. He also explains the diversity within memory types—such as episodic, semantic, and procedural memories—and why they’re all processed differently. Delving into extraordinary memory phenomena, he discusses hyperthymesia, false memories, and cases of severely deficient autobiographical memory, illustrating the varied ways people experience memory. This episode is a rich journey into the science and experience of memory, concluding with a refreshing reminder: sometimes, forgetting can be just as beneficial as remembering, offering us a balanced perspective on our memory's true role in daily life.

Matt returns this week to unpack the complexities of narcolepsy, a neurological sleep disorder often misunderstood and misdiagnosed. He starts by defining narcolepsy, explaining its profound impact on brain and body functioning and its chronic nature, which often diminishes patients' quality of life. Narcolepsy affects about 1 in every 2,000 people, yet most go undiagnosed due to limited awareness and medical training on sleep disorders. With a closer look at the causes, Matt explores how the brain's sleep-wake regulator, orexin, malfunctions in those with narcolepsy, disrupting their sleep cycles and resulting in excessive daytime sleepiness and sleep "attacks."
Delving into symptoms, Matt highlights narcolepsy’s hallmark indicators, such as cataplexy—a sudden loss of muscle tone triggered by strong emotions—and frequent REM sleep disruptions that can lead to vivid hallucinations upon sleep onset. The episode covers diagnostic tools, from sleep studies to brain chemical tests, which help identify the condition. While there is currently no cure, Matt discusses various treatment options, from alertness-enhancing medications to emerging research and therapies. This episode calls for greater compassion and support for those with narcolepsy, emphasizing the importance of awareness and education in managing this life-altering disorder.

Matt revisits the concept of "sleep divorce," or "sleep separation" in this latest episode, examining its effects on relationships and well-being. He cites studies showing that up to one in four couples in the U.S. and U.K. sleep in separate rooms, a statistic often underestimated due to stigma. While many fear that sleeping apart harms intimacy, Matt presents data indicating that it can actually enhance sleep quality and intimacy by promoting better-rested bodies and increasing hormones like testosterone and estrogen.
He also discusses new research on the psychology of co-sleeping, revealing that despite poorer sleep quality, many couples feel more satisfied when sharing a bed, driven by a deep-rooted need for social connection, known as "somato longing." This episode encourages listeners to reflect on their own sleep habits and offers advice on discussing sleep separation with partners, emphasizing that the choice to sleep together or apart should prioritize open communication and individual health.

Matt and Eti return today for another AMA session where they dive into even more fascinating and often quirky sleep questions that have been submitted by listeners. In this installment, our duo explores the evolutionary puzzle of why we sleep, despite the apparent risks it poses for survival. They also share insights into how early organisms, like earthworms, exhibit sleep-like states, which raises the question: did wakefulness evolve from sleep?
As the episode continues, the pair tackle practical questions from listeners on how to fall asleep faster and stay asleep. Relaxation techniques like deep breathing, mindfulness, and avoiding clock-watching are highlighted as effective tools to combat sleep struggles. They also emphasize the importance of maintaining regular sleep schedules, avoiding heavy meals, and reducing caffeine intake. Matt goes on to suggest that minimizing noise pollution can make a big difference, and earplugs might be the solution for many. Eti notes that she swears by silicone ones, and, while she and Matt have no financial relationship to, or sponsorship from, the company, you can check out the earplugs Eti loves here.

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.

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 and Dr. Eti Ben Simon are back today to answer more of your excellent questions with their latest AMA installment - #8!
They begin by delving into the intriguing world of lucid dreaming, explaining how it enables dreamers to become aware and even control their dreams, and move on to discussing the scientific methods used to study lucid dreaming, such as using eye movements as a form of Morse code to communicate with researchers. Through studies involving MRI scans, scientists have validated that the brain areas associated with movements become active during lucid dreams.
Matt and Eti also provide valuable insights into sleep hygiene, emphasizing the importance of maintaining a regular sleep schedule and creating an optimal sleep environment. Additionally, our duo highlight unconventional tips such as avoiding naps if you struggle with sleep and taking a mental walk instead of counting sheep to help fall asleep.

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.
