Potential beneficial effects of foot bathing on cardiac rhythm

Purpose: Foot bathing therapy is a simple technique that induces sensations of comfort and relaxation. The aim of this study was to examine the effect of foot bathing therapy on heart rate variability (HRV) parameters in a healthy population. Methods: Participants were twenty healthy female subjects (median age=20.67 years, SD=1.04). The recording ECG was applied for 5 minutes before and for 5 minutes after foot bathing therapy of 10 minutes. Subjects rested for 10 minutes without recording ECG in order to stabilize autonomic parameters. The digital signals were then transferred to a laptop and analyzed using LabChart® software (MLS310/7 HRV Module). Results: Almost all HRV parameters increased and heart (pulse) rate and LF/HF ratio decreased after foot bathing therapy compared with before foot bathing therapy. Conclusions: These results indicate for the first time in humans that foot bathing might induce a state of balance between sympathetic and parasympathetic systems and might be helpful to prevent possible cardiac arrhythmias.
