Is Circadian Rhythm The Ultimate Biohack? (Yes: Especially For Post-Menopausal Females!)

Episode Description from the Publisher

Could optimizing your circadian rhythm be the most important health intervention of all? In this show, I take a trip around the 24-hour clock, exploring fascinating ideas about light, leptin, metabolism, sleep, and circadian biology. We&rsquo;ll look at why direct outdoor light in the morning matters, why eating after dark can cause more fat storage than eating the same number of calories at a different time, and how our modern use of artificial light may be extending &ldquo;summer&rdquo; throughout the year. I also explain why the hours from midnight to 3:00 AM are so important for darkness, leptin, human growth hormone, and the body&rsquo;s overnight repair processes&mdash;and why these issues may be especially relevant for post-menopausal women. I wrap it all up with four simple ways to get your circadian rhythm working in your favor: mellow evenings, a dark and cool sleeping environment, energetic mornings, and napping when you need it. I explain why caffeine can override the sleepiness signal your body is trying to send you, and why insufficient sleep can make you 20% slower at everything you do&mdash;while making you less aware of it. &nbsp;I&rsquo;ll also share emerging research on sunlight and immune regulation, including the fascinating field of photoimmunology, plus the sleep-cooling technology I&rsquo;m currently enjoying with the Somnus Sleep System. The big takeaway? Before you chase complicated health protocols, make sure you&rsquo;re respecting the biological rhythms that have governed human health for far longer than artificial light, smartphones, and Netflix queues. &nbsp; LINKS: Brad Kearns.com BradNutrition.com B.rad Whey Protein Superfuel - The Best Protein on The Planet!
