The charitable reading of "better sleep" is "sleep habits that allow for a healthy amount of sleep". A lot of people have habits that give them insufficient sleep.

Yeah, "get better sleep" is usually followed with "by buying this thing". No one makes any money if you go to sleep earlier.

My experience is being surrounded by people who sleep eight hours a night and then check their ring data or whatever nonsense to convince themselves that they could do better.
