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 fitness trackers and smartwatches, which connect to smartphones for added functionality. These devices often use sensors to collect data and provide insights to users. Many wearables also offer features like notifications, GPS tracking, and music control. As technology advances, wearables are becoming more integrated into daily life, promoting health awareness and convenience for users.
