Wearables track personal health metrics through integrated sensors and software that monitor vital statistics. Devices such as smartwatches and fitness trackers record data like heart rate, steps taken, calories burned, and sleep patterns. By utilizing Bluetooth or Wi-Fi, they synchronize data with mobile applications for analysis and long-term tracking. This real-time feedback empowers users to manage their health proactively, set fitness goals, and gain insights into their overall well-being, contributing to informed lifestyle choices.
