ResCalm: Neuroscience with Heart-rhythm Biofeedback
ResCalm is a free app for Android phones (like Samsung 5.2 and higher level) that can be used as a mobile heart rhythm biofeedback device jointly with a finger sensor. You can buy the fingersensor (hardware) in the webshop of this site. With this Heart Rate Variability biofeedback tool you can train in 8 weeks reaching positive results: more resilience and better selfregulation by balancing your Autonomic Nervous System (ANS).
When this can be relevant? The ANS is dysregulated in extreme stressfull situations, sleeping problems, posttraumatic stress, depression, panic disorder, but also with exam anxiety, peakperformance anxiety and ADHD.
With ResCalm you can choose between 6 different breathing rhythms. It is important to find your own personal breathing rhythm in which breath and heart rhythm are resonating. Resonance in breath-heart rhythm effects a signal to the brain (amygdala): now there is safety, in which you can have optimal contact with yourself and with other people. It effects better concentration, quietness, focus and resilience.
Neuroscience in Heart Rate Variability (HRV) with more than 20 years studies and more than 5000 scientific articles show that HRV is an excellent marker of the Autonomic Nervous System and Health, and HRVbiofeedback can bring a dysregulated stressfull mind and body in balance. Resonant breathing and longer exhalation than inhalation are the key for autonomic balance. Autonomic balance creates quietness, better concentration, better sleep and less anxiety.
