I regularly use my Apple Watch Series 7 with the Sleep app to track my sleep. I am not sure why the app shows stages “awake”, “REM”, “Core” and “Deep”, while in scientific literature, stages N1, N2, N3, REM and Awake are typically described in PubMed.

Apple engineers and support people are not here. In fact, everyone here is a fellow user, just like you. My guess would be that the Watch and the sensors and algorithms can’t currently detect the other phases.
Hey! I’m a medical student and I made a scientific article about sleep. Why in the app “Sleep” do we have only four phases? Because we know about two phases and five stages.
