hrv is a measurement of stress. it has been established that persons suffering with mental and physical illnesses such as ptsd have chronically lower hrv values compared to the rest of the population (normalised based on biological sex and age).

prana implements hrv biofeedback, an evidence-based way to improve hrv. additionally, hrv is simplified to health points (hp), to easily show the effects of lifestyle choices, helping users to make better choices in diet, sleep and self-care practices.

anxious persons breathe shallowly and rapidly. by consciously altering the breath in a certain way, heart rate variability is improved, stress is relieved, and overall health is improved.

prana implements this evidence-based breathing protocol to aid relaxation and sleep.

our brains are full of electromagnetic activity. these electromagnetic (or brain) waves have certain frequencies specific to certain mental and physical states (relaxed, focus, anxious, sleep, meditation).

prana implements brainwave entrainment, an evidence-based method of entraining desired states.
