Smartwatches Evolve with Digital Biomarkers, Challenge U.S. Healthcare Integration
Smartwatches have advanced significantly, now capable of monitoring a wide range of health metrics such as heart rate, stress, and physical activity. Researchers are developing digital biomarkers, which combine these metrics into clinically meaningful insights. This innovation aims to shift healthcare from reactive to preventive care. However, the U.S. healthcare system, which is primarily designed for episodic care, faces challenges in integrating this continuous data. Privacy concerns also arise, as wearable data is not always protected under federal health privacy laws unless included in medical records.
