Heart Rate Variability
Heart rate variability (HRV) is an important measure of the autonomic nervous system's capacity to regulate and adapt to stress. It is a measure of the fluctuations in intervals between heartbeats and reflects the balance between the sympathetic and parasympathetic nervous systems. HRV is often used to assess the risk of cardiovascular disease and to monitor the response of the autonomic nervous system to various medical treatments, interventions, and lifestyle changes. Studies also suggest that HRV can be used to indicate one's overall physical fitness level and health status. By monitoring HRV, individuals can take proactive steps to improve their health and well-being.
