Wearable devices don't actually measure psychological excitement. They measure physiological arousal through signals like HRV and EDA, which rise during exercise, anxiety, excitement, caffeine intake, and countless other situations. Without context, sensors can't distinguish why your body is activated. The future of stress tracking lies in combining biometrics with movement, behavior, and user-provided context instead of relying on physiological signals alone.
