Wearables in healthcare are redefining how individuals monitor health, turning everyday signals—steps, heart rate, sleep quality, respiration, and activity—into actionable, clinician-sharable data that informs daily decisions, supports proactive management of chronic conditions, and creates a continuous feedback loop between home monitoring and professional guidance, as patients become active partners in care and data literacy grows while the boundary between inside-clinic care and daily life blurs, with devices ranging from smartwatches and patches to more advanced implants feeding real-time streams to clinicians, researchers, and care teams, enabling coordinated prevention and timely interventions.These devices connect to apps, cloud platforms, and provider systems, translating raw measurements into intuitive dashboards, trend analyses, and personalized alerts that align with patients’ routines, privacy preferences, values, and cultural contexts, enabling earlier conversations, stronger adherence, and a more patient-centered cadence of care across primary, specialty, and urgent care settings, including accommodations for mobility constraints, caregiver involvement, and cross-setting data flows.
