In a recent study conducted at the University of Pittsburgh and published in the October volume of Psychosomatic Medicine, researchers found that high-frequency heart rate variability, an indirect measure of parasympathetic (vagal) control over variations in heart rate, was associated with lower production of proinflammatory cytokines.
This study of 183 healthy adults, provides initial evidence that vagal activity may represent a pathway linking psychosocial factors to risk for inflammatory disease.
Heart rate variability can be regulated through slow, steady breathing. Biofeedback is a wonderful tool for teaching improved heart rate variability.
