Welcome Back to season 14 of the Neuroscience Meets Social and Emotional Learning Podcast where we connect the science based evidence behind social and emotional learning and emotional intelligence training for improved well being, achievement, productivity and results using what I saw as the missing link since we weren't taught this when we were growing up in school. The Application of Practical Neurosc. I'm Andrea Samadhi and seven years ago launched this podcast with a question that I've never truly asked myself before. And that is if productivity and results matter to us, and they do now more than ever, how exactly are we using our brain to make them happen? And most of us were never taught how to apply neuroscience to improve productivity, our results or our well being. About a decade ago, I became fascinated by the Mind Brain Results connection and how science can be applied to our everyday lives. And that's why I've made it my mission to bring you the world's top experts so together we can explore the intersection of science and social and emotional learning. We'll break down complex ideas and turn them into practical strategies we can use for predictable science backed results. Now, as we're nearing the end of season 14, here it's been all about reflection. As we've looked back and reviewed our past interviews, our goal has not been about nostalgia or just remembering these interviews. The goal has been about integrating what we've actually learned, taking what we know, aligning it with how the brain actually functions, and then applying it consistently enough to see change in outcomes. And if there's one thing this season has reinforced, it's sustainable. Success is not built on intensity or just focus alone. It's built on alignment. And as we move into What's Next Season 15 In January, the focus shifts from just understanding this alignment to now bringing this alignment into a tangible physical form or actually embodying what we're learning. Not more information, but better execution. And after hundreds of conversations with neuroscientists, educators, peak performers and thought leaders, one truth keeps resurfacing. Lasting success is never about doing more. It's about alignment. Alignment between how the brain actually works, how emotions drive behavior, and how daily habits compound over time. Season 14 has been about stepping back. Not to reminisce, but to integrate what we've learned into our current life. I knew the minute that I was sent a couple of video clips from our past episodes and I'd actually forgotten about what the interview was about. And while I thought I had implemented the ideas from our past guests, I knew I had some work to do myself. So for this reason, we spent season 14 and will resume with season 15 next January January reviewing past episodes with the goal of noticing what we've now aligned that's bringing us results into our daily life. And just to think back when we started this podcast seven years ago, the goal was simple. To bridge neuroscience research with practical strategies that we could all actually use. What I didn't fully appreciate then was what only became clear through repetition, reflection and real life application is that information alone doesn't create change. Understanding the brain doesn't matter if we ignore what to do with the information that we release each week. You know those next steps to implement how to improve our sleep, reducing our stress, practicing emotional regulation with consistency. And this is what actually changes who we are at our core, our identity. So season 14 has been all about connecting those dots, listening again to conversations with voices like Dr. John Medina, Dawson Church, Bob Proctor, Dr. John Brady and Frederica Fabricius and so many others. One pattern became impossible to ignore. The brain thrives on simplicity, repetition and finding emotional safety to implement these concepts, not intensity or a quick fix. So we'll take the time with each interview review to offer ways for all of us to implement the lessons learned so that when we finish 2026, we'll be able to look back and and see where our changes all began. This week we move on to part three of our review of episode 72 with Dr. Shane Crieto and his book Peak Sleep Performance for Athletes that was recorded back in July of 2020. Just a reminder, in part one of this series, we covered how strategic napping, morning brain habits and even the Silva method all work together to reset your brain, boost performance and transform your health from the inside out. In part two, we continued with our review, diving a bit deeper into sleep deprivation and its impact on performance. Whether you're an athlete or just someone looking to improve productivity. In part three today we'll go a bit deeper into the impacts of concussions and brain injuries with our sleep and performance. So let's go back to 2020 and revisit what Dr. Creato had to say about sleep in this last episode featuring Dr. Shane Creato. And in this first clip of this episode with Dr. Creato, he dives into the connection with concussions and sleep. He says most people who've had a.

Concussion end up with sleep problems. It makes a lot of sense right when you think about the brain and how it regulates asleep and wakeful cycles and then it get jarred or hit. But what people don't realize is that even a Mild head injury can really damage your brain. Even if you're not officially diagnosed with a concussion, you don't have to lose consciousness to have a concussion. You don't even have to have any symptoms to have your brain injured in some way. And then little injuries along the way add up over time. So the brain is as soft as butter and it's in a hard, bony skull. Anything that jars it, even whiplash, can cause your brain to be injured. And it all accumulates over time. What's interesting, Andrea, is that the same regions of the brain that are most damaged in head injuries are also damaged in sleep deprivation and also damaged in alcohol use. The frontal lobes, the temporal lobes, the parietal lobes at the top of the brain.

Now we've got five key takeaways from Dr. Creato's clip. First takeaway, concussions and sleep problems are tightly linked. Sleep disturbances are one of the most common long term consequences of concussions because the brain directly regulates sleep wake cycles. Now, my daughter had a concussion through her sports a few years ago and I did ask her if she felt like the concussion affected her sleep afterwards. And her response was reassuring to me. While it did impact her sleep at the time, once her brain had healed, she went right back to sleep as usual, showing that our brain can be injured and and heal, which shows its true resiliency. Takeaway 2. You don't need to lose consciousness to injure your brain. Mild head injuries, whiplash, or repeated small impacts can injure the brain. Even without a formal concussion diagnosis or obvious symptoms, you do have to think back to any time where you think you had an incident where your brain was jarred. Keeping in mind that the consistency of our brain is like butter and it's contained in a hard skull. So any sort of jarring will likely have an impact. Takeaway 3. Brain injuries are cumulative. Small, repeated micro injuries add up over time, quietly impairing cognitive performance, emotional regulation and recovery. And you'll know this once you've had one concussion because doctors will always ask you, is this your first concussion? For this very reason. Takeaway 4. The brain is physically vulnerable. Remember, the brain's soft tissue sits inside a rigid skull, so any jarring motion can cause damage, even outside of contact sports. And the first person I learned about traumatic brain injuries, TBIs was from Dr. Daniel Aman, who specialized in transforming mental and physical health with his work at Amen Clinics. And his website is full of tips for brain health, including his concussion rescue program that has helped NFL Players, Championship boxers and thousands of everyday people and his treatment is centered around his clinics that are in various locations in the U.S. they're in Chicago, Dallas, Fort Worth, Los Angeles metro area, Miami, Fort Lauderdale area, New York metro, Orange county, and there's even a new clinic in Phoenix, Scottsdale metro and then one in San Francisco Bay area. And the treatment plans at his clinics are targeted for each person's situation. They include things like hyperbaric oxygen therapy, neurofeedback, hormone evaluation and replacement and targeted nutraceuticals. Takeaway 5 Sleep deprivation damages the same brain regions as head injuries, so the frontal, temporal and parietal lobes that are critical for decision making, emotional regulation, memory, focus and awareness. They're all impaired by head injury, poor sleep and also alcohol use. Takeaway 6 Sleep is not passive, it's protective and reparative. Quality sleep is one of the primary tools the brain uses to heal, detoxify and restore neural function. So why does this matter beyond just athletes? Dr. Crieto's insights also applies to students so head injuries impact sleep loss. Educators and leaders under cognitive load and stress, professionals relying on those executive functions and emotional control and anyone who's experienced whiplash falls or repeated stress and poor sleep sleep loss silently weakens the same systems that we depend on for peak performance. Some practical tips to improve brain health and sleep. We've covered these, but first, treat sleep as neurological recovery, aiming for seven to nine hours consistently every night. Prioritize regular going to bed and wake times, even on weekends. Tip 2 Protect those frontal lobes. Avoid alcohol close to bedtime because it fragments REM and deep sleep and reduce late night decision making and screen time exposure. Tip 3 Respect those mild injuries anytime you've got a head jolt or whiplash. Reduce your cognitive load. Let your brain heal, avoid intense workouts temporarily and increase sleep duration to increase repair. Tip 4 Optimize your sleep environment. Dark, cool and quiet rooms. No screens 60 minutes before bedtime. Use wind down routines to cue your nervous system that you're preparing to go to sleep. Tip 5 Stack recovery habits. Light morning movement and daylight exposure, taking magnesium or glycine if appropriate. And I do take Qualia magnesium before sleep every night and it has improved the quality and duration of my sleep. Also breath work or parasympathetic activation before sleep helps. And finally, think about long term brain health. Sleep debt and micro injuries compound over years. Thinking about recovery today protects your cognition for tomorrow. Now moving into Dr. Credo's second video clip where he shares college students and.

High school students who are sleep deprived. Their GPAs plummet and they're twice as likely in some cases to drop glasses and quit. That's a big thing. We know that certain brain regions are affected when you're sleep deprived. For example, if you're sleep deprived, one all nighter can result in your hippocampus area in the temporal lobes. That helps with new learnings. It essentially shuts down. Its functioning drops by 40%. So imagine having a 40% decline in learning. How are you going to go through school? That's the difference between getting an A and flunking out. So it does affect your ability to concentrate. It affects your ability to process, retain information, manipulate information, and if you're irritable, frustrated, have a short tolerance for doing things. How are you going to attempt a math problem? I hated math. I was terrible at it in high school. And I realized looking back it was probably because one of the reasons was, besides the fact that I was bad at it, was sleep deprivation.

Some key takeaways from Dr. Credo's second clip 1. Sleep deprivation directly lowers academic performance. So when high school and college students are sleep deprived, their GPA drops significantly. Dropout and course withdrawal rates increase. And sleep loss isn't just a tired problem. It's an academic risk factor. And our second takeaway one all nighter can reduce learning capacity by up to 40%. So one single night without sleep can reduce activity in the hippocampus, in the temporal lobe, the brain's center for new learning and memory function. And this is the difference between excelling and failing. Dr. Creato puts it plainly. That's the difference between getting an A and flunking out. Who knew how important our sleep was? Takeaway 4 Sleep loss blocks every step of learning. When we're sleep deprived, students struggle to process new information, retain what they're learning, and manipulate and apply knowledge. So problem solving, math and reasoning. Takeaway 5. Emotional regulation collapses with sleep loss. Irritability, frustration and low tolerance rise sharply, making it far harder to persist through challenging tasks like math or complex thinking. Takeaway 6. Finally, many learning struggles are actually sleep struggles. Dr. Credos Reflection is powerful. What he once thought about himself being bad at math, he now knows was largely chronic sleep deprivation, impairing his brain's ability to learn. So why does this matter for students and educators, and all of us for that matter, sleep deprivation mimics learning disabilities. It undermines motivation and confidence, and it disproportionately affects adolescents whose brains biologically need more sleep. And this reframes sleep as an academic intervention, not just a lifestyle choice. Some practical tips to improve learning and sleep for our students Protect sleep before learning aim for 8 to 10 hours for teens, 7 to 9 hours for college students. Avoid those all nighters they sabotage the hippocampus. Tip 2 Study smarter, not later. Front load studying. Make it earlier in the evening and use sleep to consolidate memory, not replace it. Tip 3 Reduce cognitive overload at night. No screen 60 to 90 minutes before bed and dim those lights to support melatonin release. Tip 4 Keep a consistent sleep schedule. Same bed and wake times, even on weekends. Tip 5 anchor mornings with light. Get outside that morning sunlight that resets circadian rhythm. It improves alertness and learning readiness. And finally, address irritability as a sleep signal. If you've got a short fuse with a student or your child, that means they're pretty much running on empty. And also emotional dysregulation often precedes academic decline. So to review and conclude this week's episode 380 when you place these two clips side by side, a clear neuroscience story emerges. 1. Sleep loss and brain injury affect the same systems. Head injuries, including mild cumulative ones, sleep deprivation and alcohol use all impair the frontal, temporal and parietal lobes, the brain's regions that are responsible for focus and decision making, emotional regulation, memory and learning, problem solving and persistence. This means sleep deprivation isn't just being tired, it's functionally similar to brain injury. 2. Learning collapses without sleep Dr. Credo highlights a striking find finding 1. All nighter can reduce hippocampal function by around 40%. And the hippocampus is essential for new learning, memory encoding and academic performance. So a 40% drop in learning capacity is not subtle. It's the difference between understanding versus confusion, confidence versus frustration, and progress versus withdrawal or quitting. 3. Academic struggles are often neurological, not motivational. Across both clips, we see that sleep deprivation lowers grade point average, increases course dropouts, increases irritability and frustration, and reduces tolerance for effortful tasks like math or complex thinking. Many students who are labeled as unmotivated, bad at math, or not academically inclined are actually sleep deprived. The damage is cumulative, but so is recovery. Just as micro injuries add up over time, so does sleep debt. But the hopeful message across both clips is sleep is the brain's primary repair mechanism. Quality consistent sleep restores learning circuits, supports emotional regulation, protects long term brain health, and improves performance across academics, sports and life. Our final thoughts to review and conclude episode 380 with Dr. Shane cannot separate sleep from performance, learning or brain health. Dr. Credo's work reframes sleep as a neurological necessity, an academic intervention, a protective factor against brain injury, and a competitive advantage for athletes and students alike. Whether we're talking about a student pulling an all nighter, an athlete with repeated minor head impacts, or a professional operating on chronic sleep loss, the message is the same. Sleep is not optional, it's foundational. Protect sleep and you protect learning, emotional resilience, decision making, and long term success. And at this point, it just reminds me of the six health staples that we're covering. Sleep is at the top, and so is exercise and nutrition. When one health staple breaks down, especially sleep, the others lose their power. And with that thought, we're coming to a close to completing season 14, a season rooted in reflection. Our goal this year was to look back at past episodes and intentionally integrate these neuroscience and SEL concepts into our daily lives. Not just understand them, but now live them. Season 15 will begin in January while we'll continue reviewing past episodes with a renewed focus, shifting insights into tangible, visible daily results that you can apply in real time. But before the calendar turns, we have something special planned. Over the holiday season, we'll be releasing a book based series that I've been working on for quite some time now. I've wanted to to explore this for several years now. The upcoming series will be think and grow Rich for Sales and it offers a fresh and practical lens on this timeless classic. Even if you're not in the sales profession, I strongly encourage you to listen. The truth is, we all have to sell every single day. We sell ideas, influence, solutions and we sell ourselves. When you understand the skill science behind a successful sale, you'll begin to see powerful shifts in your relationships, your confidence and your productivity. So we'll see you soon, sometime over the holiday season with this new series, and until then, we do hope you're enjoying a season of rest, reflection and connection. Thank you as always for being a part of our journey.
