The truth is, early parenting choices, like sleep training and letting babies cry it out, can affect how their brain and body develop for years to come. Many well-meaning parents follow these popular methods, only to see their kids later struggle with anxiety, depression, or behavioral issues that seem to come out of nowhere. That’s because early attachment and nervous system development shape a child’s mental health in ways we don’t always see.

Everything that happens in the first years of life, from how you respond to your baby’s cries to how connected they feel, helps build their brain, nervous system, and their ability to feel safe and calm. Even common parenting habits can create hidden stress, making it harder for children to grow into resilient, emotionally healthy adults.

In this episode, Dr. Darcia Narvaez joins Dr. Aimie to talk about what babies really need for healthy brain development, emotional safety, and attachment. You’ll also learn how parents and practitioners can begin to repair early childhood trauma and help heal the nervous system, no matter the age.

You’ll hear about:

• How sleep training and crying it out disrupt a baby’s developing nervous system
• The link between early separations and anxiety, depression, and attachment issues later in life
• How your own childhood experiences influence your health, relationships, and parenting style
• Practical ways to rebuild connection and help your child’s nervous system heal
• Why the vagus nerve is essential for emotional regulation in children
• How common newborn medical procedures can cause lasting trauma
• Why children need love and connection, not constant performance for approval

Whether you’re a practitioner wanting to understand how early attachment trauma affects adult clients, or a parent looking for nervous system regulation techniques and coregulation strategies to support your child, this episode offers science-backed insights and practical tools you can use right away.

Dr. Darcia Narvaez is a Professor of Psychology Emerita at the University of Notre Dame. She is the co-founder of the public and professional educational outreach project the Evolved Nest Initiative whose nonprofit mission is to share her science research into developing appropriate baselines for lifelong human wellness and providing guidelines for fostering full human potential.

Do you feel like your body is always on high alert? Does emotional stress lead to a racing heart, skin breakouts, or stomach problems? If you're an empath or highly sensitive person (HSP), you might be experiencing mast cell activation, and it’s more common than you think.

In this episode, Dr. Aimie explores the hidden biology behind why sensitive people get sick from stress. Here’s what’s happening: Your body has special immune cells called mast cells. They act like security guards. But after trauma or chronic stress, these cells can become overreactive. They can treat everyday experiences like threats, even normal conversations or emotional triggers.

In this episode, you'll learn:

• Why your body treats emotional stress like a physical emergency
• How your immune system gets stuck in “danger mode” (and why it’s not your fault)
• How to naturally calm an overactive nervous system
• Supplements for mast cell activation
• Dr. Aimie’s favorite technique that resets your nervous system
• How blood sugar levels affect emotional reactivity
• Simple daily habits to support nervous system healing

Whether you're someone who feels emotionally or physically drained after social interactions, a practitioner absorbing clients' trauma, or someone who seems to absorb energy from others, this episode will give you practical tools to feel safer in your body and break the cycle of overwhelm.

🎧 Want more support? Listen to Episode 131: Why Empaths Get Stuck in Grief and How to Move Through It for deeper guidance on trauma and emotional regulation.

Highly sensitive people and empaths often feel like they're drowning in grief while others seem to handle loss with ease. They absorb emotions from everyone around them, feel overwhelmed by everyday environments, and find themselves reaching for things they know aren't good for them just to numb the pain. But what if that sensitivity is actually a person's greatest strength?

In this episode, Dr. Aimie reveals why highly sensitive people experience grief so differently and how understanding your nervous system's unique needs can transform your relationship with both sensitivity and loss. She shares her own vulnerable story of self-sabotage after her best day ever, showing how even those who understand trauma can still get hijacked by grief.

You'll find out about why being an empath isn't about becoming less sensitive, but learning to support your sensitive system so you can hold pain without being overwhelmed by it. Dr. Aimie explains how your sensitivities can either drain your energy or become your superpowers, and why energy management is actually the key to living your life's purpose.

• How to tell if you're a highly sensitive person
• Why empaths feel grief more deeply and get overwhelmed faster than others
• Simple ways to support your nervous system
• How to tell which sensitivities drain your energy and which ones are your strengths
• Why highly sensitive people numb emotional pain in self-sabotaging ways
• What to do when grief takes over and you feel out of control emotionally
• The biggest challenge for highly sensitive people and how to handle it
• Easy ways to support your nervous system before you get overwhelmed

Whether you’re someone navigating grief yourself or a practitioner supporting sensitive clients, this episode offers practical insights to help you understand and support sensitive systems through the grieving process, transforming sensitivity into a strength.

Your mind says you’re safe, but your body still feels tense, overwhelmed, and stuck in danger mode. Why does this happen?

In this mini episode, Dr. Aimie goes into the biology behind why mental and emotional healing doesn’t always translate into physical healing. You’ll learn how trauma gets “stuck” in your nervous system, why your body can keep sending danger signals even when your mind feels better, and practical ways to help your body feel safe enough to recover.

Your nervous system works like a dashboard, constantly checking if you can handle what’s happening or need to shut down. When it stays stuck in survival mode, even after therapy, it can cause chronic pain, fatigue, and other symptoms. The good news is, you can help your body feel safe again and start to heal.

In this episode, you'll find out more about:

• The difference between stress vs. trauma (and why it’s not about the event itself!)
• Why your body creates a personal safety filter based on past experiences
• How inflammation, toxins, and hidden stressors send danger signals to your nervous system
• Why your body’s natural healing shuts down when you’re in survival mode
• Simple ways to track and shift your nervous system state every day

Whether you’re doing your own healing or supporting clients who still feel stuck physically despite mental progress, this episode reveals the missing piece of trauma recovery. You’ll gain a clearer understanding of the body’s signals and walk away with practical tools to help the body catch up with the mind.

🎧 For more on chronic pain and trauma biology, listen next to Episode 130: Why It’s Not Stress That Causes Chronic Pain and What Really Does.

Chronic pain affects millions of people who've been told their symptoms are just from stress. They've tried relaxation techniques, stress management, and lifestyle changes, but nothing really seems to work. They’re left feeling stuck, exhausted, and frustrated that their body just won’t heal.

But why does the body stay in pain even when the injury has healed?

In this episode, Dr. Aimie look at what most people believe about chronic pain. Instead of blaming stress, she shows how chronic pain actually comes from trauma stored in the body, and explores what's really going on and why this matters so much for healing.

Drawing from her own experience with chronic shoulder pain after a collarbone fracture, Dr. Aimie explains how her body was storing trauma, not just stress. Even after surgery and treatments, the pain wouldn't go away until she discovered what was really happening in her body.

You'll discover the difference between stress and trauma responses, why your body might be stuck in a chronic trauma response, and the hidden biochemical imbalances that make some people more likely to develop chronic pain.

You'll learn:

• [1:45] Why stress does NOT cause chronic pain (and what actually does!)
• [5:20] The critical line of overwhelm that turns stress into trauma
• [11:34] What happens in the nervous system when you feel trapped and powerless
• [16:33] Why unresolved trauma keeps your body stuck in a danger response
• [21:15] The role of biochemical imbalances and why they increase pain sensitivity
• [26:06] How oxidative stress and mitochondria contribute to functional freeze
• [30:12] The hidden link between copper excess, anxiety, and chronic pain
• [34:52] Practical steps to repair your biology and help your body feel safe again

Whether you're someone struggling with chronic pain or a practitioner seeking better tools to help clients, this episode reveals why understanding trauma biology, not just stress management, is the key to breaking free from chronic pain and reclaiming your life.

Have you or your clients ever felt exhausted, anxious, or even physically ill after a therapy session? Or wondered why emotional breakthroughs sometimes leave you feeling worse before you feel better?

In this mini episode, Dr. Aimie answers EDMR therapist Rebecca's question about why people sometimes get physical symptoms after making progress in therapy, and shares simple strategies to help prevent this from happening.

She goes into the biology behind how your nervous system is constantly deciding whether you're safe or in danger, and why digging into painful memories or feelings can make your body think it's under attack, even when you're actually healing.

You'll learn more about:

• Why your body thinks feeling emotions is dangerous
• How your "energy bank account" affects what you can handle in therapy
• Why you might feel sick AFTER therapy sessions
• How things like poor sleep and processed food make therapy harder on your body
• Why your nervous system is always checking if you're safe or in danger
• Two simple things you can do after therapy to feel better

Many people get stuck on their healing journey. They feel lost and confused. They've spent years in therapy, tried meditation, read all the books but still feel like they’re just surviving instead of truly living. This is way more common than we would like to believe, and quite discouraging for those dealing with stress, burnout, or old emotional wounds.

Even when you know you're safe, your body might still feel like it’s in danger. 

That’s because healing isn’t just about mindset, it’s about your nervous system. And most healing methods skip the steps your body actually needs to feel safe at the nervous system level.

In this episode, Dr. Aimie explains why one often gets stuck and what the nervous system really needs to move from overwhelm and a functional freeze into calm aliveness. You’ll learn how the body experiences a trauma, why it holds on even for years after, and the step-by-step roadmap to give it what it needs to engage its own healing mechanisms.

You’ll learn more on:

• [1:46] Why many people avoid connecting with their body and stay “in their head”
• [4:05] How to tell if you’re disconnected from your body
• [5:48] What happens in your body during a trauma response (and how it can get stuck)
• [8:48] Why just telling yourself “you’re safe” doesn’t make your body believe it
• [12:49] The hidden equation your nervous system uses to decide if you’re still in danger
• [15:49] The surprising trait that can block healing  
• [18:16] Common signs you’re in shutdown mode
• [21:51] The 3 major roadblocks that can slow down healing
• [22:52] Why you need cycles of stress and rest to heal
• [27:36] The 3-phase healing roadmap
• [29:32] How emotional healing works just like physical healing—and why skipping steps keeps you stuck

Whether you're working on your own healing or helping others, this episode gives you the missing piece to understand what’s really going on in the body and how to finally move forward.

What if the autoimmune condition you're dealing with today was actually programmed into your immune system decades ago during childhood?

In this mini episode, Dr. Aimie answers a listener’s question about the biological mechanisms connecting early attachment trauma to autoimmunity, and most importantly, what to do about it.

She goes into the biology behind how childhood fear literally programs your immune system at the cellular level, creating a biological foundation for autoimmune conditions that can emerge years or decades later, often triggered by additional stressors like accidents, infections, or major life events.

You’ll learn more about: 

• Why fear causes inflammation
• How early fear creates overactive brain immune cells (microglia) that cause symptoms like brain fog and decision fatigue 
• The three key immune system pathways that determine whether your body stays in "inflammation mode" or switches to "repair mode"
• Practical actions you can take to rebalance your immune system

Whether you're a practitioner working with autoimmune clients or someone with your own autoimmune journey, this episode reveals the hidden biological connections between early life experiences and immune dysfunction and offers hope through practical interventions that work at the cellular level.

Listen to Episode 128: How Attachment Drives Anxiety, Autoimmunity and Chronic Illness to explore the six core attachment pains and their biological impacts.

Don't forget to pre-order my new book, Biology of Trauma! 

Many people push others away while desperately craving connection. Others battle chronic pain, digestive issues, or autoimmune conditions that seem to have no clear cause. But why is this?

The answer often lies in unresolved childhood attachment trauma, specifically the experiences we had before we had words to make sense of them.

This is why someone can have what looks like a good childhood but still struggle with anxiety, digestive problems, chronic pain, or autoimmune issues as an adult. The body remembers what the mind has forgotten.

In this episode, Dr. Aimie breaks down the biology of early emotional pain and how it becomes stored in the body as chronic symptoms later in life. You’ll discover the six core attachment wounds, why the body learns to stay in survival mode, how unresolved early trauma shapes your nervous system, immune system, and relationships in adulthood,  and most importantly, how to become your own safe person. You'll learn:

• [2:08] Why babies need to be held to survive and what happens when they're not
• [8:45] How to recognize if "it's not safe to relax" is your core attachment pattern
• [11:35] The health impacts of early attachment trauma
• [15:20]How fear becomes stored in the body as inflammation and chronic illness
• [20:49] The six core attachment wounds that shape our nervous system and relationships
• [25:30] How childhood wounds create the belief "I'm not capable" and lead to chronic overwhelm
• [30:08] The surprising link between people-pleasing and chronic pain
• [32:45] How brain fog, histamine intolerance, and depression can stem from attachment wounds
• [37:50] The three-phase roadmap to safely heal stored trauma in the body

Whether you're someone living with unexplained chronic health issues or a practitioner supporting clients who seem stuck, this episode will help you understand the deep connection between childhood trauma, nervous system dysregulation, and adult symptoms and what it really takes to heal.

Your nervous system’s main job isn’t to make you happy. It’s to keep you safe. That’s why, even after the danger is over, your body can still act like it’s under threat. In this mini episode, Dr. Aimie goes into the biology behind how trauma gets stuck in the body and why it’s so hard to “just move on.”

You’ll learn how something called the body trauma loop keeps your system in survival mode, and how the brain’s ability to learn (neuroplasticity) can actually lock in trauma patterns over time.

In this episode, you’ll hear about:

• The 3 trauma survival responses: shutdown, disconnection, and freeze
• Why your body keeps flipping between stress and shut down
• How your brain and body learn to repeat trauma patterns automatically
• How things like inflammation and oxidative stress keep your nervous system stuck
• Why just saying “you’re safe” isn’t enough
• A step-by-step process to help your body shift out of survival and into safety
• Simple, body-based tools (somatic practices) you can use daily to calm your nervous system

Whether you're a practitioner or someone who's tired of feeling anxious, frozen, or burned out, this episode will help you understand what’s happening in your body and how to start changing it.
