Psilocybin and the Nervous System - How Mushrooms Help Us Regulate and Heal
Your nervous system is the gateway to every experience you have - love, fear, joy, connection. When it’s dysregulated, life can feel like a constant cycle of anxiety, numbness, or overreaction.
Psilocybin, the active compound in magic mushrooms, doesn’t just expand consciousness - it helps restore balance to the body’s most intricate system of safety and connection.
The Nervous System as the Foundation of Healing
The nervous system is our internal compass. When it feels safe, we can rest, connect, and think clearly. When it feels threatened, it prepares for danger - tightening muscles, raising heart rate, and shutting down digestion and emotion.
Trauma, stress, or prolonged fear can trap the body in survival mode. Over time, this leads to exhaustion, anxiety, depression, or chronic pain.
Psilocybin helps interrupt that pattern by inviting the nervous system into a state of calm awareness. It doesn’t erase trauma - it helps the body remember what safety feels like.
How Psilocybin Regulates the Brain and Body
Scientific studies from Johns Hopkins and Imperial College London show that psilocybin temporarily quiets the default mode network - the brain region responsible for self-criticism and repetitive thinking (Carhart-Harris et al., 2016).
This shift allows communication between previously disconnected brain regions, promoting flexibility and emotional processing.
In simple terms: psilocybin helps the brain “breathe.” It creates space for new perspectives and patterns to emerge.
At the same time, psilocybin increases serotonin activity, which regulates mood and supports relaxation. Many people describe a deep sense of peace, release, or emotional clarity during or after a session.
The Body’s Experience of Safety
Regulation isn’t a mental concept - it’s a physical one.
During psilocybin journeys, clients often report waves of warmth, energy, or vibration as the body releases stored tension. Tears, trembling, or spontaneous movement are common signs of the nervous system discharging old stress responses.
When the body feels safe enough to release, it no longer needs to protect. That’s where healing begins.
Psilocybin and Polyvagal Theory
Through the lens of the polyvagal theory, psilocybin helps shift the body from sympathetic activation (fight-or-flight) or dorsal shutdown (freeze) into the ventral vagal state - calm, social engagement, and connection.
This is why after a psilocybin experience, people often describe feeling more open, connected, and emotionally resilient. Their system has tasted regulation — and now knows the way back.
Integration - Anchoring Regulation into Daily Life
The medicine shows what’s possible, but integration keeps it alive.
After a psilocybin journey, grounding rituals help stabilise the nervous system. Breathwork, movement, time in nature, and connection with safe people anchor the state of openness into everyday life.
This is why in my Transform Arc, integration is never an afterthought - it’s where the real rewiring happens.
Through coaching and somatic practices, clients learn how to regulate without needing the medicine. That’s where freedom truly begins.
Find Trust
Psilocybin doesn’t just expand your mind - it restores your body’s trust in itself.
By calming the nervous system and reconnecting mind and heart, it helps you meet life with more presence, less fear, and greater capacity for love.
