Wearable technologies monitor health metrics by using various sensors to track physiological data. Common metrics include heart rate, steps, sleep patterns, and caloric expenditure. Data collected is sent to a connected device, where it is analyzed, allowing users to monitor their health in real-time. By utilizing algorithms, wearable devices can provide insights on trends and potential health issues, ultimately promoting better lifestyle choices. The integration of mobile apps further enhances user interaction, making health data more accessible and understandable.
