The Internet of Things (IoT) is moving healthcare from “reactive” to “proactive.” Wearable sensors—ranging from smartwatches to medical-grade patches—now monitor vital signs like heart rate, oxygen saturation, and even skin temperature in real-time.
These devices create a continuous stream of data that can alert a physician to a potential cardiac event or respiratory distress hours before the patient feels symptoms. For the elderly or those with chronic conditions, this “hospital-at-home” model provides a safety net that increases independence while decreasing the burden on emergency departments.
