The 21-Day Nervous System Tune-Up (NSTU) is a short, self-paced online course created by nervous system specialist Irene Lyon. It introduces the foundations of somatic and nervous system regulation, helping participants understand how stress and trauma affect their health, and teaching simple, daily practices to build resilience, calm, and vitality.
-
Video lessons introduce key concepts in nervous system science and trauma healing.
Guided audio and movement practices teach participants how to notice and shift survival states like fight, flight, or freeze.
Daily exercises build awareness, regulation skills, and capacity over three weeks.
The course can be repeated as often as needed to deepen integration.
-
NSTU is designed as an accessible entry point into Irene Lyon’s broader programmes, including SmartBody SmartMind™ (SBSM).
It draws on Somatic Experiencing, Feldenkrais, and neuroplasticity principles, blending education with experiential practice.
Once purchased, participants have ongoing access and can revisit the course at their own pace.
