Heart rate variability (HRV) provides the best available means of measuring the interaction of sympathetic and parasympathetic tone, that is, of brainstem regulatory integrity.” (van der Kolk, 2006)
• The social engagement system has a regulating, calming, and soothing effect reflected in rhythmic oscillations in heart rate variability.
• Inhales stimulate sympathetic nervous system
• Exhales stimulate parasympathetic nervous system.
• Low HRV is associated with anxiety and depression
• High HRV is associated with positive emotions and resistance to stress.
