• The Heart Rate (HR) is intimately tied to the bodily expression of emotions which correlates

   to the autonomic nervous system.

• Heart Rate Variability (HRV) is a measure of neuro cardiac function that reflects heart-brain        interactions and autonomic nervous system dynamics. [McCarty et al, 2009]

• HRV is an excellent measure of anxiety, depression, etc.        [Pignotti et al, 2000]

• HRV can be used as an indicator of asthma severity. [Norio et al, 1997]

Heart Rate Variability Biofeedback Breathing 


HRV Biofeedback breathing (HRVB) techniques enable users to actively improve their HRV by synchronizing their breathing with their heart rhythms.

iFeel Labs wearable pulse sensor (FDA/CE approved) tracks the pulse in real time while iFeel Labs games teach the user how to breath effectively using HRVB technique.
