Skin Temperature
Fitbit Sense and Fitbit Sense 2 use a dedicated sensor to estimate your skin temperature variation during sleep sessions. Fitbit Charge 4, Fitbit Charge 5, Fitbit Charge 6, Google Pixel Watch 2, Google Pixel Watch 3, Fitbit Inspire 2, Fitbit Inspire 3, Fitbit Luxe, and Fitbit Versa series surface your sleep-measured skin temperature variation through existing sensors.
Everyone has a different temperature baseline. When you wear a compatible Fitbit device to sleep, it checks your skin temperature every minute. When the Fitbit app has tracked your sleep skin temperature data for at least 3 days, it estimates your baseline temperature. As you continue to wear your Fitbit device to sleep, the Fitbit app uses up to 30 days of data to adjust your baseline temperature.
- Wear your device for at least 3 days, including to sleep.
- Upon waking, open the Fitbit app and tap the Skin temp variation tile.
You'll get a history of your sleeping skin temperature variations, along with any core temperature readings you manually recorded. - Tap the tile to check a history of your sleeping skin temperature variations, along with any core temperature readings you manually recorded.
- Tap a log to check a minute-by-minute record of your skin temperature variation throughout the most recent sleep session.
You may notice more variation when you check on your minute-by-minute data, as compared with your overall skin temperature variation for a sleep session. Your skin temperature changes throughout your sleep period as you move around and your body regulates itself. Your overall variation is based on your average skin temperature during a sleep session
- Wear your device for at least 3 nights, especially to sleep.
- In the morning, open the Fitbit app and tap the Health metrics tile
.
- Tap the Skin temp variation tile to get more details, including your historical data.
.- Wear your device for at least 3 days, when you go to sleep.
- When you wake up, open the Fitbit app and select the Skin temp variation tile.
- Tap a sleep record to get more details.
Skin temperature typically varies over the course of a sleep session. Factors that may cause skin temperature to vary include changes in room temperature, bedding, circadian rhythm, menstrual cycle, or the onset of an illness. Note that significant changes in ambient temperature may negatively impact skin temperature tracking.
