What it means
Total sleep combines classified overnight sleep and daytime naps. Awake periods are inferred from gaps between recorded sleeps; they are not sensor measurements. Qualifying awake gaps are at least five minutes.
Good to know
Unlogged sleep can make a recorded awake gap look longer. Awake gaps never add to actual sleep duration.
