I have resorted to hitting PCs while they are down to threaten/scare them.
Standard healing in 5e is easy mode, and the devs have said as much.
Ime the easiest way to make suffering hp damage more meaningful and involve proper opportunity cost is to (I) use the slow healing rules and (ii) either track -ve HP, or use the injuries table (or some variant).
You want to make dropping to zero hp scary and a real setback... rather than the silly healing bonus with whack-a-mole side effect that the standard death and dying rules promote.
