Heart Rate Variability and its Importance

Heart rate variability (HRV) is a crucial metric that reflects the balance between the sympathetic and parasympathetic nervous systems. A healthy heart does not beat with metronome-like regularity; instead, there are tiny variations in the time between beats, influenced by the autonomic nervous system. The sympathetic nervous system, responsible for the fight-or-flight response, increases heart rate and readies the body for action, while the parasympathetic nervous system promotes rest and relaxation. HRV is a reflection of this balance, with a high HRV indicating adaptability and recovery capabilities. Alcohol consumption, late-night habits, irregular sleep patterns, and ignoring natural rhythms can lower HRV, impacting overall well-being. Increasing HRV can be achieved through consistent sleep patterns, slow frequency breathing, sauna use, and adequate hydration.
