Wearable devices improve health monitoring by providing real-time tracking of vital signs and physical activity. Equipped with sensors, these devices can continuously measure metrics such as heart rate, step count, and sleep patterns. Data collected is often synced with mobile applications for easy access, allowing users to gain insights into their health and activity levels. Additionally, many wearable devices can alert users to potential health issues, such as irregular heartbeats, which can prompt timely medical intervention. This ongoing monitoring empowers individuals to take proactive steps towards better health management.
