While these tools track physiological metrics, users often struggle to interpret the results. A recent study indicates 45% of people in Britain track health data, though few actually understand the metrics provided. This disconnect between data collection and user comprehension limits the clinical utility of consumer wearables in managing daily health and recovery.Why it mattersHeart rate variability serves as a proxy for autonomic nervous system f
