How to check drowzing?

hi. how can i check drowzing on galaxy watch?

You posted this on Galaxy Watch for Tizen which is Galaxy Watch3 and older watches.

Are you asking this as a user or a developer? If as a user you should ask this on the Samsung Members community.

As a Tizen developer you would do this in Tizen Studio and there probably is a way to do it checking for motion, respiration and maybe heart beat.

If you have Galaxy Watch4 or newer then you would do this with Android Studio.
