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.  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.

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.

Ask Me Anything Part 5

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.
