Health data from wearable devices has grown exponentially, but abundance of metrics (heart rate, sleep scores, HRV, stress levels) can paradoxically harm wellbeing by driving obsessive self-measurement and anxiety rather than informed health planning. Dr. Thanee Thaneevan (EO LifeMED) warns that data should guide behaviour change through trend analysis and self-listening—not fuel perfectionism. Actionable insight: focus on trends over individual data points, compare only to your own baseline, and escalate only truly abnormal alerts (arrhythmias, low oxygen) to doctors; treat sleep/HRV/heart-rate metrics as supporting context, not verdicts.
