The document states that skin temperature tracking estimates the change from a personal baseline established over three nights of sleep, updated nightly, and discloses that sleep environment, sleep position, and device fit may affect measurement accuracy.

This provision describes the specific technical methodology used for skin temperature estimation, including the three-night baseline period, and identifies the environmental and positional conditions under which accuracy may be reduced. The disclosure that baseline establishment takes three nights has practical implications for users relying on the feature immediately after initial device setup.
Under this clause, skin temperature data reflects estimated change from a baseline that requires approximately three nights of sleep to establish, and readings during that initial period may not reflect the feature's standard operating accuracy. Users are informed that sleep position and environment may affect readings at any point.

Compare across platforms →"Certain Garmin smartwatches can provide an estimation of the change in the user's average skin temperature during their selected sleep window. The feature attempts to establish an initial average skin temperature baseline over 3 nights of sleep then provides the user an estimation of the nightly change in temperature from that baseline. This baseline is generally updated after each night of sleep. While every effort is made to ensure the accuracy of these estimations, there are inherent limitations with the technology that can cause inaccurate measurements. For example, the user's sleep environment, sleep position and fit of the device may impact the measurements.Excerpt from Garmin's Terms of Use
