Wearables are electronic devices that can be worn on the body, often in the form of accessories like watches, bands, or clothing. They typically track health and fitness metrics, such as heart rate, steps taken, and sleep patterns. Popular examples include smartwatches and fitness trackers, which connect to smartphones for data analysis and notifications. These devices use sensors to collect information and often feature wireless connectivity, allowing users to sync data with apps. Wearables can enhance daily life by promoting physical activity and providing insights into personal health, making them valuable tools for fitness enthusiasts and health-conscious individuals alike.
