HRV is a unique way of actually measuring the activity and tone of the nervous system as it relates to your level of stress. The brain and heart communicate and by measuring these signals we get a clear picture as to what your body thinks of your current lifestyle. You may say your not stressed but your body might argue otherwise. The parasympathetic nervous system is responsible for slowing the heart rate, increasing intestinal activity and digestion, and relaxes the muscles as well as the mind. Purposefully engaging and activating the parasympathetic nervous system is the end goal of HRV. This type of biofeedback is not a form of meditation, it is a tool for measuring the ststus of your current health.
