Discussion

Multimodal biofeedback shows improved executive functions in healthy adults using breath modulation, indicating benefits for cognitive health.

Volitional breathing significantly enhanced executive functions, particularly through Right-Nostril Yogic Breathing.
Participants showed varying effects on cardiac vagal tone; Bhastrika decreased heart interval while RNYB increased it.
Analysis utilized fNIRS and ECG, revealing important correlations between PFC activation and heart rate variability (HRV).
These findings could inform future noninvasive interventions for cognitive aging and neuropsychiatric disorders.

Shah et al. (2025) studied this question.
