What is HRV?

Heart rate variability (HRV) is a measure of how much your heart rate changes from beat to beat. It reflects the balance between your sympathetic and parasympathetic nervous systems, which regulate your stress and relaxation responses. A higher HRV means that your heart can adapt to different situations and challenges, while a lower HRV indicates that your heart is more rigid and less resilient.
