    What Huberman Gets Right About Thyroid (That Your Doctor Misses)

    Your metabolism isn't broken. It's just confused by mixed signals from your thyroid and growth hormone. Andrew Huberman talks a lot about optimizing hormones, but here's what he gets right about thyroid function that most doctors completely skip over. Your thyroid doesn't just control your energy levels - it's running about 70% of your metabolic show. And when it's not working properly, no amount of intermittent fasting or cold plunges will fix your sluggish metabolism. What you'll discover: • Why your thyroid controls 60-70% of your resting metabolic rate and what that actually means for weight management • How growth hormone peaks during your first 3-4 hours of sleep and why this timing matters more than total sleep hours • The real science behind cold exposure increasing thyroid production by 15-20% (and why it's not just hype) • How chronic stress tanks thyroid function by up to 30% through cortisol interference Nina breaks down the actual research on thyroid optimization without the wellness industry nonsense. You'll learn which strategies have real science behind them and which ones are just expensive placebos. Chapters: 00:00 What Huberman gets right about thyroid 02:30 The metabolism connection doctors miss 04:45 Growth hormone and sleep timing 07:15 Cold exposure: hype vs reality 09:30 Stress and thyroid suppression 11:45 Practical takeaways This isn't about buying special supplements or following complicated protocols. It's about understanding how your hormones actually work so you can make smarter decisions about your health.

    Why Your Brain-Body Connection Is Sabotaging Your Workouts

    Your brain isn't talking to your body the way it should. And it's costing you every time you work out, try to sleep, or deal with stress. Most people think the brain-body connection is some wellness buzzword. But there's actual science showing how this communication breakdown messes with everything from your heart rate to your pain tolerance.

You'll learn why your workouts feel harder than they should and how to fix the disconnect that's sabotaging your results. Chapters: 00:00 The brain-body communication crisis 02:15 What interoceptive awareness actually means 04:30 Breathing techniques that work (and why) 06:45 Body scanning for faster recovery 08:20 Cold exposure and nervous system training 10:15 Daily practices that stick Nina's treated enough patients to know the difference between what sounds good and what actually works.

    The Relationship Pattern That's Costing You Real Love

    Most people think they're bad at dating. They're not. They're just picking the wrong people for predictable reasons. Therapist Lori Gottlieb breaks down why smart people keep making terrible romantic choices. Turns out about 70% of us have secure attachment styles, but these folks are practically invisible on dating apps. Meanwhile, we're drawn to people who recreate childhood patterns, even when those patterns hurt. What you'll discover: • Why your brain mistakes anxiety for attraction (and how to spot the difference) • The attachment style that makes up 70% of people but gets overlooked in dating • How childhood experiences predict who you'll swipe right on as an adult • The one question that reveals if someone's actually ready for a real relationship Nina Valdez walks through the research showing people spend more time picking a car than understanding their relationship patterns. The data on this is pretty wild: folks who do personal work before dating have way higher relationship satisfaction rates. Not shocking, but the numbers are bigger than you'd think. Chapters: 00:00 Why good people go unnoticed 02:30 The attachment style lottery 05:15 Your childhood blueprint for love 08:00 Red flags vs. green flags that actually matter 10:30 The readiness question This isn't about becoming a different person to find love. It's about understanding why you keep ending up in the same situations with different faces. If you're tired of dating advice that doesn't work, hit follow.

    Your Brain on Grief: Why Loss Rewires You (And How to Heal)

    Your body knows the difference between grief and sadness. When someone you love dies, your brain literally rewires itself, firing the same neural pathways as physical injury. That crushing feeling in your chest? It's not just a metaphor. Dr. Mary-Frances O'Connor has spent two decades studying what grief actually does to your brain. Her research reveals why you can't think straight after loss, why your body feels broken, and most importantly, how to work with your brain instead of against it during the hardest moments of your life. What you'll discover: • Why grief triggers physical pain in the same brain regions as a broken bone • How your reward system keeps searching for the person who's gone, creating neurological loops • Why 80% of grieving people can't sleep (and it's not what you think) • The specific brain changes that make simple decisions feel impossible Nina breaks down the neuroscience behind loss and shares practical strategies that actually align with how your grieving brain works. No platitudes, no timeline pressure. Just science-backed approaches that honor what your mind and body are going through. Chapters: 00:00 The neuroscience of heartbreak 02:15 Why your brain keeps looking for them 04:30 Sleep, memory, and the grieving mind 06:45 When your prefrontal cortex goes offline 08:20 Working with your brain's grief response 10:00 Building resilience through understanding This episode won't fix your grief, but it might help you understand why healing takes the time it takes. Your brain is doing exactly what it's supposed to do. New episodes of Brainwaves drop every day with medical research you can actually use.
