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.

    The $2.3 Million Cost of Your Inner Critic (Dr. Ethan Kross Study)

    Your inner voice costs you $2.3 million over your lifetime. That's what University of Michigan researcher Dr. Ethan Kross calculated when he looked at how negative self-talk impacts earning potential, health outcomes, and life decisions. Most people think that critical voice in their head is just part of being human. Turns out it's more like having a toxic roommate you can actually evict. What you'll discover: • Why 80% of your 60,000 daily thoughts work against you (and the simple name trick that flips the script) • The specific brain regions that light up when you practice "self-distancing" - and why it drops cortisol by 23% • How people using Kross's techniques before public speaking had lower heart rates than those who didn't • The two-word phrase that stops anxiety spirals faster than any breathing exercise Nina breaks down the actual neuroscience here. This isn't positive thinking fluff. Kross mapped exactly what happens in your brain when you shift from "I'm stressed" to "Nina's stressed" - and the results are measurable. The research is solid, the techniques are simple, and the payoff is huge. Your inner critic has been running the show long enough.

    Why Your Brain Keeps Choosing Addiction (And How to Stop)

    Your brain starts rewiring itself after just 10 days of repeated substance use. That's not willpower failing, that's neuroscience. Ryan Soave breaks down the actual mechanisms behind addiction and the tools that work to break free. Nina digs into why some treatments have 60-70% success rates while others barely move the needle. What you'll discover: • How dopamine pathways change within days, not years • Why behavioral addictions hit the same brain circuits as drugs • The specific therapy combinations with proven track records • How social connections literally rewire your recovery odds This isn't about moral failures or finding more motivation. It's about understanding what's happening in your brain and using that knowledge strategically. Nina walks through the research on everything from medication-assisted treatment to why certain environments make relapse almost inevitable. You'll learn why some people seem to quit easily while others struggle for decades, and what the data actually shows about long-term recovery success rates. Chapters: 00:00 Why your brain picks addiction 02:30 The 10-day rewiring process 05:15 CBT success rates breakdown 07:45 Social support multiplies recovery odds 10:20 Behavioral vs substance addictions If you've been frustrated by oversimplified addiction advice, this episode gives you the real mechanisms.

    Dr. Santos: Why 90% of Happiness Research Is Wrong (And What Actually Works)
