  • #56 - Treating Your Insomnia with Michael Grandner pt 2
    Matt and special guest, Dr. Michael Grandner, continue their dialogue regarding the multifaceted world of sleep, insomnia, and their intersections with various life aspects. Together, they unveil the gender-based variations in susceptibility to insomnia, attributing higher rates among women to their willingness to express challenges. Their conversation navigates through sleep difficulties during life transitions like menopause, exploring the impact of physical discomfort and emotional changes. The podcast then takes a cultural dive, examining how race and ethnicity shape sleep patterns, revealing concerning trends in sleep disparities over time. The episode also underscores cognitive behavioral therapy for insomnia as the go-to approach, surpassing medication due to its efficacy and lower risks. The role of melatonin is demystified, clarifying its function as a time-signaling molecule that influences sleep timing.

  • #55 - Targeting Insomnia (With Dr. Michael Grandner)
    In the podcast, sleep expert Dr. Michael Grandner engages in a conversation with Matt about insomnia. They delve into the subject by defining what insomnia is, examining its causes, understanding its implications, and discussing potential remedies. An important distinction is made between short-term insomnia and chronic insomnia. They highlight that chronic insomnia often evolves into a standalone problem.One of the major talking points is the significant impact of insomnia, which is believed to affect approximately one-third of the population. There is an emphasis on its connection to both physical and mental health. Some of the physical health problems linked to insomnia include diabetes, cardiovascular issues, and inflammation. However, it is in the realm of mental health that insomnia’s effect is most stark, especially in relation to depression and anxiety disorders. Alarmingly, it is noted that insomnia can triple the risk of suicide. It is clear that the treatment of insomnia is not just about increasing the amount of sleep but also enhancing the quality of sleep for overall health improvement.Dr. Grandner doesn’t stop there; he further probes the complexities of insomnia and the phenomenon of conditioned arousal. He makes an insightful comment on how putting more effort into falling asleep can, counterintuitively, only increase stress levels. Furthermore, the conversation takes an interesting turn as they talk about how different factors like race, ethnicity, and societal influences can create disparities in sleep patterns. Another aspect Dr. Grandner touches upon is the distinct sleep challenges that women face, particularly during pregnancy and perimenopause. He also discusses how sleep can be disrupted by various factors such as medication and its timing.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. The good people at InsideTracker are one of the sponsors of this week's episode, and they are generously offering a special 25% off any one of their programs for anyone who uses the above link during the time window of this episode.InsideTracker is a personalized biometric platform that analyzes your blood and your DNA to better understand what's happening inside of you and offers suggestions regarding things that you can do to better try and adjust some of those numbers, optimize them, and, as a result, optimize you.Another sponsor this week is the biochemical electrolyte drink company LMNT, and they are very kindly offering eight free sample packs when you purchase any one of their orders at drinklmnt.com/mattwalker.

  • #54 - The Art of Napping
    In today’s episode, Matt shines a spotlight on the science behind napping and explores the optimal nap duration for various cognitive benefits. He starts by introducing the concept of napping and its benefits for the brain and body, and then discusses sleep inertia, the groggy feeling upon awakening from a nap, and its potential impact on brain performance.Matt walks through the dose-response curve of naps, starting with ultra-short power naps of five minutes or less, which show no evidence of sleep inertia but offer minimal cognitive benefits. He then progresses to 10-minute naps, which demonstrate improvements in alertness and sustained attention. The benefits continue to increase with 15-minute and 20-minute naps, enhancing alertness, concentration, and problem-solving abilities. However, sleep inertia becomes more noticeable with longer naps, such as 30-minute to 60-minute durations, although the cognitive benefits are more significant and long-lasting.Lastly, Matt shares the origin of the term "power nap" and how it emerged from research conducted by Dr. David Dinges and Dr. Mark Rosekind for the Federal Aviation Authority (FAA) to combat sleep deprivation among pilots. They discovered the benefits of preemptive napping to build resilience against subsequent sleep deprivation during long-haul flights, leading to the adoption of the term "power nap" by the FAA.Listen in today to gain valuable insights into the art and skill of napping, emphasizing the importance of finding the right nap duration to balance cognitive benefits and sleep inertia. #TheNapPodcast #NapScience #PowerNapPlease 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. The good people at InsideTracker are one of the sponsors of this week's episode, and they are generously offering a special 25% off any one of their programs for anyone who uses the above link during the time window of this episode.

  • #53 - Sleep & Antioxidants
    In this second part of his series on sleep, free radicals, and antioxidants, Matt delves into the fascinating connection between sleep and oxidative stress. He begins by recapping the previous episode's discussion on free radicals and oxidative stress, highlighting the recent studies that have revealed one of the functions of sleep: to counteract the harmful effects of free radicals. Curiosity leads Matt to question why total sleep deprivation often leads to death in different species without a clear cause. The focus shifts to a groundbreaking study from Harvard, where researchers examined oxidative stress and free radical damage in fruit flies subjected to sleep deprivation. Surprisingly, the study revealed that the oxidative damage was concentrated in the gut rather than the brain or other major organ systems. Further analysis unveiled the detrimental consequences of the free radical accumulation in the gut, including DNA damage, cell death, and tissue necrosis. Additionally, the researchers discovered that certain antioxidants, notably melatonin, offered protection and prevented premature death caused by sleep deprivation. Matt emphasizes the importance of considering the findings with caution, as the experiments were conducted on flies and not yet explored in humans. Nonetheless, the study sheds light on the precise mechanisms linking sleep deprivation, oxidative stress, and the gut, providing valuable insights into the profound impact of sleep on overall 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. The good people at InsideTracker are one of the sponsors of this week's episode, and they are generously offering a special 25% off any one of their programs for anyone who uses the above link during the time window of this episode.
