In a randomized trial of 20 healthy adults, researchers recorded EKGs during a 3-minute baseline, a 15-minute massage, and a 3-minute postmassage period. Moderate pressure massage raised the high-frequency (HF) heart-rate variability measure and lowered the LF/HF ratio, which the authors say indicates increased parasympathetic (vagal) activity peaking in the…
