A wearable device may include one or more sensors, which it may use to periodically take sensor measurements of physiological parameters (e.g., heart rate) of a user of the wearable device according to a base measurement rate (e.g., every 10 minutes). Each sensor measurement is compared to a pre-determined threshold level (e.g., predetermined at the wearable device or at a network). If a measurement exceeds the predetermined threshold level, the wearable device generates an alert at the wearable device and begins to periodically take sensor measurements at a faster threshold measurement rate (e.g., every 10 seconds) using the sensor whose measurement exceeded the threshold limit. If a new measurement falls below the threshold limit, the wearable device can return to using the base measurement rate. Thus, the wearable device's sensor-used battery power is conserved unless a sensor measurement indicates that they are needed due to a potential health risk. |
