Summary
A single session of HRV biofeedback can protect asthma patients against stress-induced bronchoconstriction, improving lung function metrics compared to baseline.
Methods
Stress challenge with HRV biofeedback intervention in asthmatics
Key Findings
- HRV biofeedback prevented stress-induced airway constriction
- FEV1% and FVC% improved compared to baseline
- Single short session showed protective effects
- Psychological stress can trigger bronchoconstriction
- Autonomic regulation impacts airway function
Limitations
Single session study, long-term effects need study
What This Means for You
If stress triggers your asthma symptoms, HRV biofeedback may help. Even brief breathing exercises before stressful situations could protect against stress-induced airway constriction.
