Many people today describe a pattern they cannot explain. Life feels manageable until something unexpected happens at work or home, then the body suddenly shuts down. The mind spins, energy collapses, irritability rises, and the only thing that feels safe is withdrawing into the couch, the phone, or Netflix. This is not laziness or burnout. This is functional freeze.
In this hol+ conversation, Dr. Taz sits down with environmental and root cause medicine expert Dr. Jessica Peatross (Dr. Jess) to reveal why so many people experience chronic fatigue, anxiety, weight gain, histamine reactions, food sensitivities and unexplained inflammation even when routine labs look normal.
Instead of chasing symptoms or isolated toxins, Dr. Jess explains how a dysregulated nervous system alters detox, hormones, digestion, immunity and gene expression. She breaks down how trauma, mold exposure, hidden infections, parasites and environmental chemicals overload the body when the vagus nerve is stuck in fight, flight or freeze. And she shows why healing is impossible when the body does not feel safe.
From childhood trauma and dorsal vagal shutdown to blocked drainage pathways, cytokine storms, reactivated viruses and misdiagnosed environmental illness, this episode reframes chronic symptoms through a lens of nervous system physiology, not personal weakness or aging.
You will learn what functional freeze looks like, why detox often makes people worse, how to identify nervous system dysregulation, and the steps Dr. Jess uses to help patients regulate, open pathways and finally begin to heal. Together, Dr. Taz and Dr. Jess outline a clear, compassionate roadmap for anyone who has ever felt dismissed, overwhelmed or stuck in a body that will not calm down.
Dr. Taz and Dr. Jess discuss:
• What functional freeze is and why it shows up in daily life
• How nervous system dysregulation drives fatigue, anxiety and chronic symptoms
• The role of mold, parasites, toxins and environmental chemicals in chronic illness
• Why detox fails when the body does not feel safe
• Vagus nerve physiology and dorsal vs ventral vagal states
• How trauma, stress and grief reshape hormones, immune function and methylation
• Medical dismissal and the reality of normal labs with real symptoms
• The drainage pathways that must open before detox
• Histamine issues, MCAS, POTS and their connection to the nervous system
• Tools that help regulate the system and support healing
• How to track progress through sleep, HRV, emotional stability and digestion
• Why healing is not linear and why support and community matter
