• Ask Me Anything Part 19: The Sleep Science of Her

  Dr. Eti Ben Simon returns for yet another AMA episode, this time specifically focussing on sleep and women. Together, they delve into the nuanced differences in sleep patterns between men and women, exploring aspects like sleep duration, quality, and architecture, including variations in deep sleep and REM sleep. They discuss how females generally sleep slightly longer, experience fewer awakenings, and have more deep sleep early in the night, alongside a quicker onset of REM sleep. The conversation also touches upon the potential health risks associated with shift work, particularly night shifts, highlighting an observed associational link with increased risks for certain cancers, such as breast and skin cancer, though emphasizing this is not necessarily causal.The discussion then transitions to the profound impact of hormonal changes on female sleep throughout different life stages. Matt and Eti examine the common sleep disturbances during pregnancy, detailing the reasons such as physical discomfort, hormonal shifts, and frequent urination, and the consequences like mood disorders and increased risk of gestational diabetes. They further explore how sleep is affected by the menstrual cycle, with changes in REM and deep sleep across follicular and luteal phases, and then tackle the significant sleep challenges during menopause, including insomnia, sleep apnea, and restless legs syndrome, discussing management strategies like HRT and CBT-I.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.Tired of untrustworthy protein shakes?

• #99 - Insomnia in 7 Days with Dr. Aric Prather

  Sleep expert Dr. Aric Prather joins Matt today for a fascinating discussion about insomnia's frustrating reality: trying to force sleep backfires; sleep arrives naturally. Dr. Prather highlights a surprising starting point: forget focusing on bedtime, prioritize a consistent wake-up time, even weekends. Noting that this anchors your internal clock and builds essential sleep pressure (the 'balloon'), he also cautions that sleeping in after a bad night disrupts this cycle. After touching on societal factors impacting sleep, the conversation shifts to managing the mental side—the stress and anxiety creating that 'tired but wired' state. Dr. Prather shares practical techniques: daytime micro-breaks, breathing exercises, and scheduling worry time to keep thoughts from hijacking the night. Listeners learn how the bedroom can become a trigger for wakefulness and how stimulus control (getting out of bed when not sleeping) breaks that association. Finally, they cover Time-in-Bed Restriction: deliberately spending less time in bed can paradoxically consolidate sleep by intensifying sleep drive, building confidence. This episode offers tools not for nightly success, but for improving sleep on average and reducing panic over occasional bad nights.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.One of our sponsors 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.

• #98 - Weighted Blankets

  Matt delves into the science of weighted blankets for sleep improvement in this week’s episode. These heavy covers (10-40 lbs) utilize Deep Pressure Stimulation (DPS), a concept originating from Dr. Temple Grandin's 1960s work. DPS is theorized to shift the nervous system from "fight-or-flight" to a calmer parasympathetic state by potentially increasing serotonin and activating brain regions involved in emotional regulation, like the insular cortex, thereby fostering a state conducive to sleep.Matt describes research whose highlights include a 2020 study where 42% of insomnia patients achieved remission with weighted blankets, and a 2021 study that showed healthy adults experienced increased deep sleep and less restlessness. Benefits are also noted for children with ADHD. Proposed mechanisms extend to reduced awakenings and anxiety. While studies show promise for specific groups, larger, objective trials are still needed. Weighted blankets (around 10% body weight) are best viewed as a potential aid alongside good sleep hygiene.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.One of our sponsors 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.

• Ask Me Anything Part 18: From Phone Radiation & Paralysis to Full Moons & Earworms

  Matt and Dr. Eti Ben Simone are back again today to answer even more of your brilliant sleep questions! They begin by discussing smartphones, noting that the direct EMF impact on brainwaves is debatable, but that psychological activation and blue light are known disruptors. Moving onto naps, Matt explains longer ones can cause "sleep inertia," while short naps (20 mins) can be beneficial, unless insomnia is present.They then examine the full moon's debated effect on sleep, and how it is possibly obscured by modern lighting. Sleep paralysis is then explained as consciousness returning before REM sleep's muscle atonia ends, while "hypnic jerks" (jolts while falling asleep) are described as the brain misinterpreting muscle relaxation as falling. Finally, they explain that waking with an "earworm" is linked to memory consolidation and active music-processing brain areas during REM sleep.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.Tired of untrustworthy protein shakes?
