Heartrate variability (HRV)
When you breathe in and out your heart rate changes which is called 'heart rate variability' (HRV) or more specifically 'respiratory sinus arrhythmia' (RSA). However, stress & anxiety reduces the heart variability.
Vasso shows you how to de-stress with the help of breathing exercises which in turn should increase the heart rate variability.

HRV can only be measured with precise heartrate detection and degrades with noisy ECGs: Bernd Porr, Peter W. Macfarlane (2024) A new QRS detector stress test combining temporal jitter and F-score (JF) reveals significant performance differences amongst popular detectors. Plos One.
