Question

When and how can I use the skin temperature measurement during sleep?

Answer

[Countries that only support the Watch]

• To use the skin temperature measurement during sleep, a Watch5 or later model must be connected to a mobile device, and the Samsung health app must be updated to the latest version.
• Once you meet the requirements, go to settings within the Cycle Tracking feature and turn on the "Predict period with skin temp" option to receive your daily representative skin temperature measured automatically during sleep. For accurate measurements, we recommended wearing the watch for at least 4 hours while sleeping at night.

[Countries that support both the Watch and the Ring]

• To use the skin temperature measurement during sleep, a Watch5 or later model or a ring must be connected to a mobile device, and the Samsung health app must be updated to the latest version.
• Once you meet the requirements, go to settings within the Cycle Tracking feature and turn on the "Predict period with skin temp" option to receive your daily representative skin temperature measured automatically during sleep. For accurate measurements, we recommended wearing the watch or the ring for at least 4 hours while sleeping at night.

If both the watch and the ring are connected to your mobile device, skin temperature will be measured only by the wearable that you select to measure with. Therefore, please select the device in in the Cycle tracking - Settings - Predict period with skin temp.
