October 11 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. Nina drops new Brainwaves episodes every day, mixing real medical research with the kind of straight talk you'd get from a doctor who actually has time to explain things.

October 11 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.

October 11 The $2.3 Trillion Brain Mistake 90% of People Make Every Day
Most people think exercise is just for their body. They're missing a $2.3 trillion opportunity happening inside their skull every time they break a sweat.
Nina breaks down the latest neuroscience showing how a simple 20-minute workout literally grows new brain cells and boosts your memory for hours afterward. Turns out your brain craves movement more than your muscles do.
What you'll discover:
• Why 150 minutes of weekly exercise increases your hippocampus by 2-3% (that's your memory center getting bigger)
• How high-intensity intervals spike brain-building proteins by 300% in just 30 minutes
• The exact workout timing that improves focus for up to 4 hours afterward
• Why people who exercise regularly cut their dementia risk by 40%
This isn't about becoming a gym rat. It's about understanding what actually happens in your brain when you move your body, and how to use that knowledge to think clearer, remember better, and stay sharp as you age.
Nina's treated enough patients to know the difference between what sounds good and what actually works. She walks through the research that's changing how doctors think about exercise prescriptions and brain health.
Chapters:
00:00 The brain growth discovery doctors missed
02:30 Why your hippocampus needs you to sweat
05:15 The 20-minute memory boost protocol
07:45 High-intensity intervals vs steady cardio for brain power
10:30 Building your personal brain fitness plan

October 11 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.

October 11 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

October 10 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:

• 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
