Skin Temperature

The module on the Index™ Sleep Monitor sleep band has a sensor designed to track variations in your skin temperature overnight. Your skin temperature changes over time, which can be related to your recent activity and sleep environment. Skin temperature can also be a sign of changes in your overall body temperature, potentially providing an early indication of illness. Watch the trends for clues to improve your sleep and health.

TIP: For women, you can also use skin temperature variations to better track your menstrual or ovulation cycle. For more information, go to www.garmin.com/garmin-technology/health-science/womens-health/.

You must wear your sleep band for three nights to establish your skin temperature baseline.
