Stuck in Freeze? The Thyroid Piece Nobody Checked  
Podcast: The Biology of Trauma® With Dr. Aimie

Description: You have been doing the work. You understand your patterns. And you are still waking up unable to face the day. When the body decides survival is the priority, it stops converting thyroid hormone into the form your cells can use. It produces an inactive version instead, called reverse T3, and that version blocks the active hormone at the cell door. The result is a body running low and slow. It is the same physiology I call chronic functional freeze. Dr. Amie Hornaman ranks reverse T3 as the single most important thyroid marker, ahead of free T3, and it is a marker almost nobody orders. She also holds that stress and trauma on their own can raise it. This is Part 1 of a two part conversation. ➡️ Full show notes, research and timestamps: https://www.biologyoftrauma.com/post/can-a-thyroid-problem-keep-me-in-chronic-freeze WHAT YOU'LL LEARN: Why a normal TSH does not settle the question of whether your thyroid is involved What reverse T3 is, and why Dr. Hornaman ranks it above free T3 How stress and trauma can shift thyroid function directly Why the hibernation state and chronic functional freeze are the same physiology What happens to the thyroid in the year after an injury or accident Why you cannot think your way out of a decision the body made below thought RESOURCES: Take the free 2-Minute Assessment for Stored Trauma: https://biologyoftrauma.com/quiz Stress or Trauma Guide The Biology of Trauma: https://www.biologyoftrauma.com/book The Thyroid Fix by Dr. Amie Hornaman Part 2 releases August 20, 2026.
