#93 - Sleeping Pills and their Alternatives with Dr. Ranji Varghese 1:00:13

23 hours ago1:00:13

1:00:13

Matt Walker welcomes Dr. Ranji Varghese back to the podcast today to complete the whole sleeping pill story by discussing newer sleeping pills, beyond benzos and Z-drugs. Together, they explore Melatonin receptor agonists (like Ramelteon) that signal sleep preparation, unlike sedating GABAergics. They also detail how DORAs inhibit the wakefulness-promoting orexin, how off-label options (ex. trazodone, low-dose doxepin) affect histamine, the risks and benefits of each. Dr. Varghese goes on to explain the mechanisms and side effect profile for each sleeping pill, including over the counter options. He stresses that all medications carry risk and require careful use, noting that sleeping pills are tools not cures, and that CBTI is preferred for chronic insomnia. Our duo finish up by reminding listeners that open communication with your doctor is vital for safe, short-term medication use.

Ask Me Anything Part 15: Beauty Sleep, Naps, 3 AM Wake-Ups & Axl Rose with Dr. Eti Ben Simon 1:09:31

22 days ago1:09:31

1:09:31

In their latest AMA episode, Matt and Eti address listener questions ranging from "beauty sleep" to 3 AM awakenings. They explore the scientific evidence supporting sleep's crucial role in skin health and perceived attractiveness, citing studies on the effects of sleep deprivation. The cognitive benefits of napping are discussed, highlighting its ability to enhance learning and memory consolidation. They also delve into the remarkable neural activity of deep non-REM sleep, including synchronized neuron firing and accelerated memory replay. The common concern of sleep debt is also a key topic. The discussion then turns to practical strategies for managing disruptive midnight awakenings. Our hosts debunk common myths and explain the physiological factors involved, such as body temperature fluctuations and adenosine clearance. They provide evidence-based techniques to quiet the mind and promote a return to sleep, including controlled breathing, non-sleep deep rest, and cognitive approaches. Finally, they touch on the concept of "hypnopedia" (in-sleep learning), largely refuted by research, and the more promising technique of targeted memory reactivation, which uses sleep cues to enhance memory.

#91 - Sleep, Ambien, Memory, and Alzheimer's 38:45

29 days ago38:45

38:45

This week, Matt Walker dives into the world of the widely used sleeping pill, Ambien (Zolpidem). He explains how Ambien, a non-benzodiazepine sedative-hypnotic, works by targeting the brain's GABA receptors, specifically the alpha-1 subunit, to induce sleep. However, this comes with consequences. Matt highlights research by Dr. Marcos Frank showing that Ambien significantly impairs memory consolidation, essentially unwiring the brain's learning processes during sleep by approximately 50%. Furthermore, the episode explores Ambien's impact on the glymphatic system, the brain's crucial waste removal process active during deep sleep. New research demonstrates that Ambien reduces the glymphatic system's cleaning capacity by about 32%, potentially hindering the removal of harmful proteins linked to Alzheimer's disease. While Ambien may offer a temporary solution for insomnia, these findings underscore the importance of natural, restorative sleep for long-term brain health. The discussion advocates for such alternative treatments as Cognitive Behavioral Therapy for Insomnia (CBTI) that address sleep issues without compromising essential neural functions. Please note that Matt is not a medical doctor, and none of the content in this podcast should be considered medical advice in any way, shape, or form, nor prescriptive in any way.

Join Matt and renowned sleep scientist Dr. Cheri Mah today as they delve into the crucial connection between sleep and athletic performance. Dr. Mah's groundbreaking research at Stanford, including her famous basketball player sleep extension study (which revealed a 9% improvement in free throws and three-pointers!), demonstrates how prioritizing sleep can significantly enhance athletic abilities. In this fascinating episode, she discusses with Matt how sleep impacts not only physical recovery and muscle repair, but also cognitive functions crucial for athletes, such as decision-making, reaction time, and mental resilience. Dr. Mah also shares insights into the specific sleep challenges athletes frequently encounter, including racing minds after competition, difficulty winding down, caffeine use, travel disruptions, and the often-overlooked impact of sleep disorders like sleep apnea. She goes on to offer practical strategies for overcoming these challenges and optimizing sleep for peak performance. Her discussion with Matt here today finishes up with a look at the importance of sleep extension, the Athlete Sleep Behavior Questionnaire for assessing sleep health, and actionable tips for creating a sleep-conducive environment and establishing a relaxing pre-sleep routine.

#89 - Does Catch-up Sleep Work? 30:02

8 weeks ago30:02

30:02

Welcome back to a new episode of the Matt Walker Podcast, where we revisit the often-discussed topic of catch-up sleep. We delve into the complexities of weekend catch-up sleep, exploring a recent study of 91,000 participants that suggests a potential link between compensatory weekend sleep and a reduced risk of heart disease. While this news offers a glimmer of hope, it's crucial to understand this benefit within the context of existing research. Studies like that of Dr. Ken Wright at the University of Colorado Boulder show weekend catch-up sleep only recovers a small percentage of sleep debt and doesn’t fully reverse the damage of weekday sleep deprivation on other critical bodily systems. We explore the impact of short sleep and weekend catch-up sleep on circadian rhythms, food consumption, blood sugar regulation, and deep sleep. This nuanced perspective emphasizes the importance of prioritizing consistent, sufficient sleep throughout the entire week for optimal health. Please note that Matt is not a medical doctor, and none of the content in this podcast should be considered medical advice in any way, shape, or form, nor prescriptive in any way.

#88 - Sleep & Sleeping Pills with Dr. Ranji Varghese 1:03:29

1:03:29

Matt Walker welcomes Dr. Ranji Varghese to the podcast this week for an in-depth conversation about sleep and prescription sleeping pills. A psychiatrist specializing in sleep medicine, Dr. Varghese begins by discussing his entry into the field which was sparked by a fascination with sleep and wake circadian rhythms. He goes on to highlight the Minnesota Regional Sleep Disorder Center's focus on parasomnias, particularly REM Sleep Behavior Disorder, emphasizing the intersection of neuroscience, physiology, and psychology in sleep medicine. As you will hear, sleeping pills, prescribed to initiate or maintain sleep, are typically used as a last resort for insomnia after other treatments fail. Dr. Varghese explains they work by modulating brain activity, often targeting neurotransmitters like GABA or melatonin receptors. He details two main classes: benzodiazepines (like Restoril and Ativan) and non-benzodiazepines (Z-drugs like Ambien and Lunesta), outlining their mechanisms, benefits, and risks. His powerful personal anecdote and the discussion of complex sleep-related behaviors underscore the critical need for careful consideration and informed decision-making when using these medications. Please note that Matt is not a medical doctor, and none of the content in this podcast should be considered medical advice in any way, shape, or form, nor prescriptive in any way. Long-time show sponsor LMNT is Matt Walker’s go-to for a sugar-free electrolyte mix.

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.
