In this Season 14 review (Part 3) Andrea revisits key insights from Dr. Shane Creado on the critical link between sleep, concussions and performance. The episode explains how even mild or repeated head impacts and sleep deprivation damage the same brain regions that support learning, memory, decision-making and emotional regulation, and how one all‑nighter can reduce hippocampal learning capacity by around 40%.

Practical takeaways include treating sleep as neurological recovery (7–9 hours), protecting the brain after head jolts, avoiding late alcohol and screens, and prioritizing consistent sleep routines to restore learning, resilience and long‑term brain health for athletes, students and professionals.

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 neuroscience.

I’m Andrea Samadi, and seven years ago, launched this podcast with a question I had 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?

Most of us were never taught how to apply neuroscience to improve productivity, results, or 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.

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-emotional learning. We’ll break down complex ideas and turn them into practical strategies we can use every day for predictable, science-backed results.

As we are nearing the end of Season 14 here, it has been about reflection as we have looked back and reviewed past interviews. Our goal has not been about nostalgia, or remembering these interviews, the goal has been about integrating what we have learned.

Taking what we know, aligning it with how the brain actually functions, and applying it consistently enough to change outcomes.

And if there’s one thing this season has reinforced, it’s this:

Sustainable success isn’t built on intensity or focus alone—it’s built on alignment.

As we move into what’s next, (Season 15) the focus shifts from understanding this alignment to bringing this alignment into a tangible, physical form, or embodiment.

Not more information—but better execution.

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 have learned into our current life.

I knew the minute that I was sent a couple of video clips from our past episodes, that I had forgotten about, that while I thought I had implemented the ideas from our past guests, I had some work to go myself.

For this reason, we spent Season 14 and will resume with Season 15 next January, reviewing past episodes, with the goal of noticing what we have now aligned, that’s bringing us results in our daily life.

Core Reflection

When we started this podcast 7 years ago, the goal was simple:

bridge neuroscience research with practical strategies people could actually use.

What I didn’t fully appreciate then—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 we release each week:

    improving our sleep reducing our stress practicing emotional regulation with consistency that actually changes who we are at the core: our identity

Season 14 has been about connecting those dots.

Listening again to conversations with voices like Dr. John Medina, Dawson Church, Bob Proctor, Dr. John Ratey, Friederike Fabritius, 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.

We will 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 will be able to look back, and see where our changes all began.

This week, we move onto PART 3 of our review of EP 72[i] with Shane Creado, MD and his book Peak Sleep Performance for Athletes recorded back in July of 2020.

✔ In PART 1[ii], 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 2[iii] we continued with our review, diving a bit deeper into sleep deprivation and its impact of performance (whether you are an athlete, or just someone looking to improve productivity).

✔ PART 3, we will go a bit deeper into the impacts of concussions and brain injuries on our sleep and performance.

Let’s go back to 2020 and revisit what Dr. Creado had to say about sleep in this last episode of this season.

In the first clip of this episode, with Dr. Creado, he dives into the connection with concussions and sleep. He says,

“Most people who have had a concussion end up with sleep problems. It makes a lot of sense when you think about the brain and how it regulates sleep and wakeful cycles and then it gets jarred. 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 need to have any symptoms to have your brain injured in some way. And then the little injuries along the way add up over time. So the brain is as soft as butter and in a hard, bony skull. Anything that jars it, even whiplash can cause your brain to be injured. And it accumulates over time. What’s interesting is that the same regions of the brain that are most damaged in head injuries are also damaged in sleep deprivation and also alcohol use. The frontal lobes, the temporal lobes and the parietal lobes at the top of the brain.”

🧠 5 KEY TAKEAWAYS FROM DR. CREADO’S CLIP
    Concussions and sleep problems are tightly linked Sleep disturbances are one of the most common long-term consequences of concussion—because the brain directly regulates sleep-wake cycles. 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. While it did impact her sleep at the time, once her brain had healed, she went back to sleep as usual, showing that our brain can be injured, and heal, which shows its true resiliency. 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 you brain was jarred, keeping in mind, that the consistency of our brain is like butter, in a hard skull, so any sort of jarring will likely have an impact. Brain injuries are cumulative Small, repeated “micro-injuries” add up over time, quietly impairing cognitive performance, emotional regulation, and recovery. You will know this once you have had one concussion, because doctors will always ask you “Is this your first concussion?” for this reason. The brain is physically vulnerable The brain’s soft tissue sits inside a rigid skull—any jarring motion can cause damage, even outside of contact sports. The first person I learned about Traumatic Brain Injuries (TBIs) was from Dr. Daniel Amen, who specializes in transforming mental and physical health with his work at Amen Clinics. His website is full of tips for brain health, including his Concussion Rescue Program[iv] that has helped NFL Players, Championship Boxers, and Thousands of Every Day People. His treatment is centered around his clinics that are in various locations in the USA, (Chicago, Dallas Fort Worth, Los Angeles Metro Area, Miami/Ft. Lauderdale, New York Metro Area, Orange County, a NEW clinic now in Phoenix/Scottsdale Metro, and San Francisco Bay Area.  The treatment plans are targeted for each person’s situation, and include Hyberbaric Oxygen Therapy (HBOT), Neurofeedback, Hormone Evaluation and Replacement and Targeted Neutroceuticals. Sleep deprivation damages the same brain regions as head injury The frontal, temporal, and parietal lobes—critical for:
      Decision-making Emotional regulation Memory Focus and awareness

—are impaired by head injury, poor sleep, and alcohol use.

    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.

🔑 WHY THIS MATTERS (BEYOND ATHLETES)

Dr. Creado’s insight applies to:

    Students with repeated minor head injuries impacting sleep loss Educators & leaders under cognitive load and stress Professionals relying on executive function and emotional control Anyone who has experienced whiplash, falls, or repeated stress + poor sleep

Sleep loss silently weakens the same systems we depend on for peak performance.

🛠 PRACTICAL TIPS TO IMPROVE BRAIN HEALTH & SLEEP

💤 1. Treat sleep as neurological recovery

    Aim for 7–9 hours consistently Prioritize regular going to bed and wake times—even on weekends

🧠 2. Protect the frontal lobes

    Avoid alcohol close to bedtime (it fragments REM & deep sleep) Reduce late-night decision-making and screen exposure

🚦 3. Respect “mild” injuries

    After any head jolt or whiplash:
      Reduce cognitive load Avoid intense workouts temporarily Increase sleep duration to increase repair

🌙 4. Optimize the sleep environment

    Dark, cool, quiet room No screens 60 minutes before bed Use wind-down routines to cue the nervous system that you are preparing to go to sleep.

🔁 5. Stack recovery habits

    Light morning movement + daylight exposure Magnesium or glycine (if appropriate) ( I do take Qualia Magnesium[v] before sleep every night and it improves the quality and duration of my sleep). Breathwork or parasympathetic activation before sleep

🧩 6. Think long-term brain health

    Sleep debt + micro-injuries compound over years Recovery today protects cognition tomorrow

In the second video clip from Dr. Creado on this episode, he shares that “When College students and high school students are sleep deprived, their GPA plummets and they’re twice as likely in some cases to drop classes and quit. That’s a big thing. We know that certain brain regions are affected when you’re sleep deprived. For example, if you are sleep deprived, one all nighter can result in your hippocampus area in the temporal lobe (that helps with new learning), it essentially shuts down its functions, dropping 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 process, retain information, manipulate information, and if you’re irritable, frustrated, have short tolerance for doing things, how are you going to attempt a math problem? I hated maths (he says) I was terrible at it in high school and I realize looking back, besides the fact I was bad at it. It was sleep deprivation.”

🧠 KEY TAKEAWAYS FROM DR. CREADO’S SECOND CLIP
    Sleep deprivation directly lowers academic performance When high school and college students are sleep deprived:
      GPA drops significantly Drop-out and course-withdrawal rates increase Sleep loss isn’t just a “tired” problem—it’s an academic risk factor.
    One all-nighter can reduce learning capacity by ~40% A single night without sleep can reduce activity in the hippocampus (in the temporal lobe)—the brain’s center for new learning and memory formation—by up to 40%. This is the difference between excelling and failing Creado puts it plainly:

That’s the difference between getting an A and flunking out.

    Sleep loss blocks every step of learning When sleep deprived, students struggle to:
      Process new information Retain what they learn Manipulate and apply knowledge (problem-solving, math, reasoning)
    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. Many “learning struggles” are actually sleep struggles Creado’s reflection is powerful: What he once thought was being “bad at math” was largely chronic sleep deprivation impairing his brain’s ability to learn.
🎓 WHY THIS MATTERS FOR STUDENTS & EDUCATORS

Sleep deprivation:

    Mimics learning disabilities Undermines motivation and confidence Disproportionately affects adolescents whose brains biologically need more sleep

This reframes sleep as an academic intervention, not a lifestyle choice.

🛠 PRACTICAL TIPS TO IMPROVE LEARNING & SLEEP 💤 1. Protect sleep before learning
    Aim for 8–10 hours for teens, 7–9 hours for college students Avoid all-nighters—they sabotage the hippocampus
🧠 2. Study smarter, not later
    Front-load studying earlier in the evening Use sleep to consolidate memory, not replace it
🌙 3. Reduce cognitive overload at night
    No screens 60–90 minutes before bed Dim lights to support melatonin release
⏰ 4. Keep a consistent sleep schedule
    Same bed/wake times—even on weekends Irregular schedules disrupt memory formation
☀️ 5. Anchor mornings with light
    Morning sunlight resets circadian rhythm Improves alertness and learning readiness
😤 6. Address irritability as a sleep signal
    Short fuse = brain running on empty Emotional dysregulation often precedes academic decline
🧠 REVIEW AND CONCLUSION: WHAT BOTH CLIPS REVEAL TOGETHER

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 Alcohol use

All impair the frontal, temporal, and parietal lobes—the brain regions 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. Creado highlights a striking finding:

    One all-nighter can reduce hippocampal function by ~40%

The hippocampus is essential for:

    New learning Memory encoding Academic performance

A 40% drop in learning capacity is not subtle—it’s the difference between:

    Understanding vs. confusion Confidence vs. frustration Progress vs. withdrawal or quitting
3. Academic struggles are often neurological, not motivational

Across both clips, we see that sleep deprivation:

    Lowers GPA Increases course dropouts Increases irritability and frustration Reduces tolerance for effortful tasks (like math or complex thinking)

Many students labeled as:

    “Unmotivated” “Bad at math” “Not academic”

are actually sleep deprived brains trying to function at a deficit.

4. 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 this:

👉 Sleep is the brain’s primary repair mechanism

Quality, consistent sleep:

    Restores learning circuits Supports emotional regulation Protects long-term brain health Improves performance across academics, sports, and life
🎯 CONCLUSION: THE BIG IDEA REVIEW & CONCLUSION – EPISODE 380

Peak Sleep Performance: Sleep as Protection, Performance, and Prevention (Part 3 of our review of EP 72 with Dr. Shane Creado, MD)

You cannot separate sleep from performance, learning, or brain health.

Dr. Creado’s work reframes sleep as:

    A neurological necessity An academic intervention A protective factor against brain injury A competitive advantage for athletes and students alike

Whether we’re talking about:

    A student pulling all-nighters An athlete with repeated minor head impacts A professional operating on chronic sleep loss

The message is the same:

Sleep is not optional. It is foundational.

Protect sleep—and you protect:

    Learning Emotional resilience Decision-making Long-term success

Just to remind us of the 6 Health Staples we are covering:

1 Sleep The foundation of brain health, learning, emotional regulation, recovery, and performance.

2 Exercise Strengthens the brain and body, improves mood, focus, and resilience—when paired with adequate sleep.

3 Nutrition Provides the fuel and building blocks for cognition, memory, and sustained energy.

4 Stress Management Supports emotional regulation, impulse control, and the brain’s ability to adapt under pressure.

5 Recovery & Downtime Allows the brain to repair, integrate learning, and heal from physical and cognitive load.

6 Environment & Daily Routines The structure that makes healthy behaviors repeatable—sleep timing, light exposure, screen habits, and consistency.

When one health staple breaks down—especially sleep—the others lose their power.

And with that thought, we are coming 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 live them.

Season 15 will begin in January, where we’ll continue reviewing past episodes with a renewed focus—shifting insight into tangible, visible, daily results 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 I’ve been working on for quite some time—one I’ve wanted to explore for several years now. This upcoming series, Think and Grow Rich for Sales, offers a fresh and practical lens on a timeless classic.

And even if you’re not in the sales profession, I strongly encourage you to listen. The truth is—we are all selling every day. We sell ideas, influence, solutions, and ourselves. When you understand the science behind a successful sale, you’ll begin to see powerful shifts in your relationships, confidence, and productivity.

We’ll see you soon—sometime over the holiday season—with this new series. Until then, we hope you’re enjoying a season of rest, reflection, and connection.

Thank you, as always, for being part of this journey.
