I don't think we know enough about it, other than to say, "sleep is important and disrupting it should be minimized." There's a medication called trazodone which is used off-label for people with issues falling or staying asleep. It increases the total percentage of time spent in slow-wave sleep (stage 3). Even though this comes at the expense of REM, in elderly people with cognitive or neurodegenerative issues, this appears to confer a protective benefit (the rate of deterioration is slowed comparatively). That said, it would probably be ideal if they slept well without medication and altered sleep architectures.
