Nina Valdez

Your doctor tells you one thing, Google says another, and that health influencer you follow swears by something completely different. The result? You're more confused about your own health than when you started looking for answers.

That's where Brainwaves comes in. Nina Valdez spent fifteen years treating patients in emergency rooms, watching people make critical health decisions based on terrible information. Now she translates the latest medical research into the kind of straight talk you'd actually get from a doctor who has time to explain things properly.

Every episode breaks down new studies about how your brain and body actually work. You'll find out why that "miracle" supplement probably isn't, what the research really says about anxiety treatments, and which wellness trends have actual science behind them. Nina's seen enough heart attacks and panic attacks to know the difference between medical facts and marketing hype.

Each episode gives you the real story behind health headlines, complete with what the study actually found and what it means for your daily decisions. No medical jargon, no agenda, just the information you need to make smarter choices about your health.

    Why You're Losing Endurance Gains Every Single Week

    Here's why your Sunday long run isn't building the endurance you think it is. Most people train endurance completely backwards. They go hard when they should go easy, skip the boring stuff that actually works, and wonder why their progress stalls after a few weeks. Nina Valdez breaks down the three energy systems your body uses and why understanding them changes everything about how you should train. What you'll discover: • Why 80% of elite athletes train at intensities that feel "too easy" • The specific heart rate zone that increases your mitochondria by 20% in 8 weeks • How your lactate threshold determines whether you hit the wall or keep going • Why most people's "moderate" pace actually sabotages their endurance gains Your body runs on three distinct energy systems, and each one needs different training to improve. The phosphocreatine system powers those first explosive 10 seconds. The glycolytic system kicks in from 10 seconds to 2 minutes. And your aerobic system handles everything longer than that. Here's what most people get wrong: they train in that middle zone between easy and hard, which doesn't optimize any of these systems. Zone 2 training feels almost boringly easy, but it's building the cellular machinery that actually makes you faster over distance. Nina explains how elite endurance athletes structure their training and why your lactate threshold matters more than your max heart rate for real-world performance. Chapters: 00:00 Why most endurance training fails 02:30 Your body's three energy systems explained 05:15 The 80/20 rule elite athletes follow 08:00 Zone 2 training and mitochondrial adaptation 10:45 How to test and improve your lactate threshold If you want the real science behind getting stronger and faster, follow Brainwaves.

    What Jordan Peterson Gets Right About Life Choices (Most People Miss This)

    Most people think Jordan Peterson just tells you to clean your room and call it self-help. But there's actually hardcore psychology backing up his approach to life decisions.

You'll get the practical tools he developed as a clinical psychologist, plus the research that shows why they actually work. Chapters: 00:00 Peterson's clinical background and why it matters 02:30 The Future Authoring program results 04:45 How to identify your actual values vs. what you think you should want 07:00 The psychology behind "clean your room" 09:15 Writing techniques that change behavior 11:00 Creating a decision-making framework If you're tired of making choices based on what other people expect, this episode gives you a research-backed way to figure out your own path.
