Why You Can’t “Think” Your Way Out of Anxiety (It’s Your Nervous System) | Dr. Nicole LePera

What It Covers

Holistic psychologist Nicole Le joins Dr. Mark Hyman to examine why childhood trauma becomes encoded in the nervous system rather than just the mind. The conversation covers the ACEs score, attachment theory, somatic therapy, and Le's five-pillar reparenting model — explaining how nervous system dysregulation drives both mental and physical chronic disease across generations.

Key Questions Answered

• •Nervous System vs. Cognitive Insight: Understanding childhood patterns intellectually does not stop automatic physical stress responses. When the body detects a perceived threat — such as sending a refusal email — the nervous system triggers chest tightening and panic before conscious thought intervenes. Healing requires working directly with the body's stress response, not accumulating more self-awareness or talk therapy insights alone.
• •ACEs Score as Health Predictor: The Adverse Childhood Experiences questionnaire measures attachment disruption across roughly 12–15 questions covering abuse, neglect, parental separation, and emotional unavailability. Higher scores correlate directly with adult diagnoses including cancer, heart disease, diabetes, obesity, autoimmune conditions, anxiety, and depression. Anyone can take the free ACEs assessment online to identify their baseline trauma load and understand downstream health risks.
• •Three-Signal Body Check-In Practice: Heart rate, breath pattern, and muscle tension are the three primary physiological signals that shift during stress activation. Building a daily habit of scanning these three markers — noticing jaw clenching, raised shoulders, or held breath — creates the awareness needed to interrupt chronic sympathetic overdrive before it compounds. Most people are so habituated to baseline stress they no longer register it without deliberate prompting.
• •Completing the Nervous System Cycle: Somatic experiencing, developed by Peter Levine, targets the incomplete stress-response cycle that keeps the nervous system stuck in either sympathetic activation or dorsal vagal shutdown. For shutdown states, gradual movement and muscle softening — not abrupt cold plunges — safely discharge stored emotional energy. For hyperactivated states, slowing breath and movement pace allows the parasympathetic system to return the body to homeostasis naturally.
• •Epigenetic Transmission of Stress States: Trauma adaptations pass across generations through epigenetic changes, where offspring are biologically prepared for the environment their ancestors faced. Stress experienced in utero further calibrates the developing nervous system toward danger. This means an individual's chronic dysregulation may originate not only in their own childhood but in their parents' or grandparents' unresolved survival responses encoded before birth.
• •Relational Neuroplasticity as the Repair Mechanism: The brain was wired through early relationships and can be rewired through safe relationships at any age. Consistent daily practices — slowing movement, elongating exhales, body scanning — gradually shift the nervous system's default state. A secure relationship with a therapist, partner, or community provides the co-regulation template the nervous system originally lacked, making change measurable and cumulative rather than dependent on single breakthrough moments.
