Abstract
Objective
This study aimed to evaluate the effects of slow-paced breathing (SPB) and humming breathing on heart rate variability (HRV) and affect.
Methods
The study included 16 healthy adults. HRV was measured for five min under three conditions: rest, SPB (5-second inhale, 5 s exhale; administered using the EliteHRV application), and humming breathing (Bhramari Pranayama). The Visual Analogue Scale (VAS) assessed anxiety, stress, relaxation, and confidence across baseline, rest, SPB, and humming breathing conditions.
Results
Both SPB and humming breathing significantly increased HRV, with higher Standard Deviation of all Normal-to-Normal intervals (SDNN), Total Power (TP), and Low Frequency (LF) values than those in the rest condition. The VAS scores indicated higher relaxation levels during rest, SPB, and humming breathing than at baseline. No significant differences were observed between SPB and humming breathing in HRV or VAS measures.
Conclusion
These findings suggest that humming breathing is a viable alternative to SPB for enhancing HRV and autonomic regulation, without requiring specialized equipment or feedback.
期刊介绍:
Physiology & Behavior is aimed at the causal physiological mechanisms of behavior and its modulation by environmental factors. The journal invites original reports in the broad area of behavioral and cognitive neuroscience, in which at least one variable is physiological and the primary emphasis and theoretical context are behavioral. The range of subjects includes behavioral neuroendocrinology, psychoneuroimmunology, learning and memory, ingestion, social behavior, and studies related to the mechanisms of psychopathology. Contemporary reviews and theoretical articles are welcomed and the Editors invite such proposals from interested authors.
