Flow is not 'just in your head' — it produces measurable physical symptoms through well-understood neurobiological pathways.
Why Flow Causes Physical Symptoms
The brain and body are not separate systems. Flow activates:
- The HPA axis: releasing cortisol that affects virtually every body system
- The autonomic nervous system: creating the physical experience of threat
- Inflammatory pathways: affecting immune function and tissue health
- The enteric nervous system (gut-brain axis): digestive symptoms common in flow
Common Physical Symptoms of Flow
- Muscle tension, headaches, and chronic pain patterns
- Digestive symptoms: IBS, nausea, appetite changes
- Sleep disruption and fatigue
- Cardiovascular: heart palpitations, elevated blood pressure over time
- Immune effects: increased susceptibility to illness
When Physical Symptoms Are Primarily Flow
Physical symptoms from flow are real, not imaginary. But they're best treated by addressing flow directly, alongside symptomatic relief when needed.
