Heart rate variability (HRV) measures the variation in time between consecutive heartbeats. Higher HRV indicates a well-regulated autonomic nervous system and better cardiovascular fitness.
HRV reflects the balance between sympathetic (fight-or-flight) and parasympathetic (rest-and-digest) nervous systems. Higher HRV means your body can transition smoothly between states — essential for both performance and recovery.
Regular aerobic exercise, quality sleep (7 to 9 hours), stress management, moderate alcohol consumption and consistent nutrition all improve HRV over time. Chronic stress, poor sleep and overtraining reduce it.
Ashwagandha in SodaPeak supports parasympathetic tone through cortisol reduction. CoQ10 supports cardiac efficiency. Both contribute to the physiological state that produces higher HRV.
