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.
