Heart Rate Variability (HRV) is an important indicator of autonomic nervous system function and overall health. This submission explores the relationship between HRV and well-being, highlighting how HRV can be used to monitor and improve physical and mental health. Practical interventions to enhance HRV and their implications for health and wellness are also included. Heart Rate Variability (HRV) measures the variation in time between consecutive heartbeats. It reflects the balance between the sympathetic and parasympathetic branches of the autonomic nervous system. Understanding HRV’s impact on well-being can provide valuable insights into an individual’s health parameters and stress resilience.
