Recalibrating Stress Resilience: Psilocybin Effects on the HPA Axis and Cortisol
Clinical studies show psilocybin recalibrates the Hypothalamic-Pituitary-Adrenal (HPA) axis, restoring normal diurnal cortisol rhythms in chronically stressed patients.
Chronic Stress and HPA Axis Dysregulation
Prolonged psychological stress causes blunted or hyperactive cortisol secretion, damaging vascular tissues and suppressing immune responsiveness.
Post-Treatment Cortisol Normalization
Following a guided psilocybin session, patients exhibit restored baseline salivary cortisol curves, reflecting a systemic recalibration of the stress response.
