Wearables enhance personal health monitoring by providing real-time data about an individual's physiological metrics, such as heart rate, activity levels, and sleep patterns. These devices, including fitness trackers and smartwatches, enable users to track their health metrics continuously, fostering a proactive approach to well-being. This data can be synced with mobile apps, allowing users to set goals, receive feedback, and make informed lifestyle choices. Additionally, wearables can alert users to health issues and support remote monitoring by healthcare providers, thus improving patient outcomes and enhancing disease management.
