Wrist Temperature is a metric that tracks the temperature of your skin at the wrist while you sleep. Monitoring this data helps you establish a personal baseline, making it easier to notice deviations that could signal changes in your body, such as the onset of a fever or shifts in your menstrual cycle.
Your wrist temperature is not the same as your core body temperature, which is typically measured with a thermometer. Instead, it reflects how your body regulates heat, especially during rest. The app tracks this temperature nightly to establish your normal range.
Tracking changes in your wrist temperature provides valuable insights into your overall wellness. A significant increase or decrease from your established baseline can be an early indicator of physiological changes. For example, a sustained rise in temperature could suggest your body is fighting off an illness. It is also a key metric for understanding and predicting phases of the menstrual cycle, as body temperature naturally fluctuates with hormonal changes.
Your wearable device uses integrated sensors to measure your skin temperature during the night. Over time, the app establishes your personal baseline and will highlight any night where the temperature deviates significantly from this normal range, helping you correlate these changes with how you feel.
This article explains how Wrist Temperature is measured during sleep to establish a personal health baseline. By tracking deviations from this norm, you can gain early insights into potential illness, hormonal shifts, and other changes in your body, empowering you to better understand your overall wellness.
