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.

    The Glucose Fix for Anxiety and Depression That Science Ignored

    What if your depression and anxiety aren't actually mental health problems, but metabolic ones your brain can't solve? Dr. Chris Palmer just dropped research that changes everything we thought we knew about treating mental illness. Turns out your brain might be starving for the right fuel, and antidepressants can't fix a metabolism problem. What you'll discover: • Why people with mental illness die 15-20 years earlier (and it's not suicide) • How ketogenic diets showed 70% improvement in bipolar patients • The insulin resistance crisis affecting 88% of Americans that doctors miss • Why your brain burns through 20% of your body's energy despite being tiny Nina breaks down the studies pharmaceutical companies don't want you reading. She's seen too many ER patients whose "psychiatric" symptoms disappeared once their blood sugar stabilized to ignore this connection anymore. This isn't about blaming diet culture or shaming anyone. It's about understanding that your brain is an organ that needs proper fuel to make neurotransmitters, and most of us are running on metabolic fumes. Chapters: 00:00 The hidden metabolic crisis 02:30 Why psychiatric medications aren't enough 05:15 Brain energy and mitochondrial dysfunction 07:45 Ketogenic protocols for mental health 10:20 Starting your own metabolic reset The research is clear, but your doctor probably hasn't read these studies yet. Nina has, and she's translating the science into steps you can actually take. If you want straight medical talk without the wellness industry nonsense, hit follow. Brainwaves drops new episodes every day, and tomorrow Nina's covering why that "healthy" breakfast might be sabotaging your mood all morning.

    Huberman Reveals Why You Can't Trust Your Instincts

    Your body is constantly receiving chemical messages that bypass your conscious mind completely. That whiff of your ex's cologne that makes your heart race? The way you instantly relax when you smell fresh bread? It's not coincidence - it's your olfactory system running the show behind the scenes. Nina Valdez breaks down why your nose might be your most underestimated sense organ. Turns out, those smell molecules hit your brain faster than you can register pain, and they're making decisions about attraction, fear, and memory before you even know what hit you. What you'll discover: • Why your olfactory neurons are the only brain cells directly exposed to the outside world • How smell signals reach your brain in just 150 milliseconds - faster than pain • Why women's smell sensitivity can increase 1000x during certain cycle phases • The science behind literally smelling fear and stress on other people Chapters: 00:00 Your nose as a direct brain connection 02:30 The 150-millisecond smell highway 05:45 How hormones supercharge smell sensitivity 08:15 The chemistry of fear detection 10:30 Why smell memories stick so hard This isn't just about having a good nose - it's about understanding how chemical signals influence your daily interactions, relationships, and gut reactions in ways you never realized. Nina connects the latest neuroscience research to explain why that "something feels off" sensation might actually be your olfactory system picking up on real chemical cues. Your instincts aren't as mysterious as you think. They're just faster than your conscious awareness. If you're ready to understand how your body actually processes the world around you, hit follow.

    The Hidden War Inside Your Mind That's Destroying Your Peace

    That critical inner voice telling you you're not good enough? It's actually trying to protect you. Dr. Richard Schwartz discovered something remarkable while treating eating disorder patients in the 1980s: we all have different "parts" inside our minds, each with its own job. That harsh critic isn't your enemy. It's a protector that learned early on to keep you safe by pointing out potential failures before others could. Nina breaks down how Internal Family Systems therapy works and why research shows it's so effective for trauma, depression, and anxiety. Turns out your mind isn't one unified thing - it's more like a family with different members who sometimes fight. What you'll discover: • How trauma creates protective "parts" that can become problematic later • The 8 core qualities of your authentic Self (hint: curiosity and compassion are built-in) • Why that perfectionist voice developed and how to work with it instead of against it • Simple techniques to access the calm, confident part of you that's always been there Chapters: 00:00 What are "parts" and how do they form? 02:30 The protector that became your inner critic 04:45 Your authentic Self and its 8 qualities 07:15 How IFS heals trauma at the root 09:30 Practical steps to befriend your parts The research backing IFS is solid, with studies showing significant improvements in PTSD, depression, and relationship satisfaction. But more than that, it just makes sense when Nina explains it. Your mind isn't broken. It's actually working exactly as designed - you just need the user manual.

    The Pet Mistake Every Owner Makes (And How To Fix It)

    Your dog isn't being "stubborn" when they ignore you—they're probably just bored out of their mind.

You'll learn why that "dominance" training approach is based on debunked science, how to tell if your pet is genuinely stressed versus just being dramatic, and simple changes that can fix most behavioral problems without expensive trainers.

    Why Doctors Don't Tell You About Your Brain's Built-In Painkiller

    Your brain manufactures morphine. Literally. It produces natural opioids more powerful than prescription painkillers, but most people never learn how to activate this built-in pharmacy. Nina breaks down the fascinating neuroscience behind your brain's pain control system and reveals the specific techniques that can reduce suffering by up to 30% without any medication.

    The $3,400 Sleep Mistake 87% of Americans Make Every Night

    Night shift nurses figured out something most of us completely missed: how to manipulate our body's internal clock like a light switch. While 87% of Americans toss $3,400 annually at mattresses, sleep apps, and supplements that barely work, people who work rotating schedules have cracked the code on controlling when they feel awake or exhausted. The secret isn't what you sleep on. It's understanding your circadian rhythm works like a 24-hour timer you can actually reset. What you'll discover: • Why 30 minutes of bright light (10,000 lux) can shift your sleep schedule by 3 hours • The 2-degree temperature drop that signals your brain it's bedtime • How eating dinner at the wrong time messes up your sleep more than caffeine • Why red light doesn't destroy your sleep but blue light delays melatonin for 3 hours Your liver, kidneys, and digestive system all have their own internal clocks that respond to light, food, and temperature. When these get out of sync, you end up exhausted during the day and wired at night. But when you know which buttons to push, you can literally program when you want to feel sleepy or alert. Nina breaks down the actual research on circadian biology that pharmaceutical companies and mattress companies don't want you knowing about. Turns out the solution isn't expensive. It's just specific. Chapters: 00:00 The $3,400 sleep industry lie 02:30 How night shift workers hack their circadian rhythm 05:15 The light therapy protocol that works 08:00 Temperature tricks for deeper sleep 10:45 Meal timing that resets your internal clock This changes everything about how you approach sleep problems.
