Wearable devices track health metrics through various sensors and technology, providing users with real-time feedback on their wellness. For instance, fitness trackers and smartwatches utilize accelerometers and heart rate monitors to measure physical activity, heart rate, and sleep patterns. These devices sync data with mobile apps, enabling users to analyze their fitness trends and set health goals. Furthermore, advanced wearables can monitor additional metrics such as blood oxygen levels and stress-related biometrics. By providing insights into daily activity and overall health, wearables encourage individuals to make healthier lifestyle choices and promote awareness of their well-being.
