Wearables can collect a wide range of data, including:
1. Physical Activity: Steps taken, distance traveled, and activity intensity. 2. Heart Rate: Continuous monitoring of heart rate variability. 3. Sleep Patterns: Duration and quality of sleep, including REM cycles. 4. Respiratory Rate: Number of breaths per minute. 5. Blood Oxygen Levels: Monitoring oxygen saturation levels. 6. Electrocardiogram (ECG): Some advanced wearables can track electrical activity of the heart.
