Heart Rate Variability (HRV)
Heart rate variability (HRV) is the physiological phenomenon of variation in the time interval between heartbeats. It is measured by the variation in the beat-to-beat interval, a known indicator of central nervous system balance. The main inputs are the sympathetic and parasympathetic nervous system (PSNS) and humoral factors. A wide range of low to high blood pressure is high HRV and indicative of a flexible nervous system. And unresponsive heart-rate, low HRV, has been correlated to post-traumatic-stress-disorder (PTSD), cardiovascular ailments, diabetes and other conditions. HRV biofeedback training is best achieved with a personalized breathing pattern leading to physiological balancing and is associated with a large reduction in self-reported stress.
Sens.ai uses a very accurate PPG (photoplethysmography) sensor in the headset earpiece to measure HRV. The Sens.ai app guides you through resonance breathing exercises to train your HRV, and sync up your heart rate with harmonic frequencies in your brain. The goal of the HRV biofeedback training is to achieve coherence - a consistent rhythmic heart rate pattern associated with a high functioning PSNS. This relaxed state will help you relax and improve your brain’s responsiveness to neurofeedback. HRV Coherence is one of the data points tracked in the Sens.ai app.
By reading your brainwaves and your heart rate, Sens.ai programs can use the mind-body connection to personalize and accelerate your cognitive development.
