hrdayin provides a platform to measure the HRV

The best non-invasive measure of the Autonomic Nervous System

Heart Rate Variability (HRV) is the time interval between two heart beats. This time interval might change from one heartbeat to another. Lower the HRV means that the time interval remains the same always and a high HRV means that the time interval variation exists. HRV offers a non-invasive indicator of autonomic nervous system activity.

In general, low HRV means a sign of the stressed state. It indicates reduced parasympathetic cardiac control and high possibilities of being associated with disorders ranging from diabetes mellitus to sleep problems, as well as difficulty regulating emotions and typically, High HRV means sign of the relaxed state. This is sign of healthy condition and is associated with the sympathetic nervous system.

Sympathetic activities are such as intense physical exercise, as well as periods of mental stress – Increased heart Rate & decreased HRV. Parasympathetic activities (relaxing, doing yoga, meditating), in contrast - Decreased heart rate & increase heart rate variability. Creating balance between the two nervous systems (Sympathetic and Parasympathetic) is very much essential. A healthy individual has strong sympathetic and parasympathetic systems, which includes the ability to shift between them.
