The advanced sensors and algorithms in wearables help translate raw data into actionable metrics, allowing for a deeper understanding of one’s health, fitness, or treatment efficacy. Commercial devices (like a smartwatch) track daily steps, calories burned, sleep quality, and heart rate variability. Specialized wearables from a doctor (like an insulin pump or neurostimulator) remotely monitor activity for a particular function. Regardless of their design, all wearables offer impressive utility that empowers users to lead healthier lives and better communicate with their healthcare provider.
