WHAT'S BIOFEEDBACK?
Heart Rate Variability (HRV) Biofeedback is a technique that can directly affect physiological and psychological factors through deep breathing exercises and is an ideal strategy to help us self-regulate and better cope with stressful situations
Practically speaking, HRV Biofeedback consists of providing an individual with real-time feedback on instantaneous heart rate and respiration changes while being instructed to breathe at low frequencies
You can learn more about the psychological and physiological benefits of deep breathing and HRV Biofeedback, at HRV4Biofeedback.com
HOW CAN I BENEFIT FROM BIOFEEDBACK?
Life can be demanding, from both a physical and psychological point of view
Our health and performance can be affected by how we are able to effectively cope with stressful situations and deal with anxiety, or in broader terms, our ability to emotionally self-regulate is key
The goal of HRV Biofeedback is to improve self-regulation, therefore impacting positively our health and performance
