Is Player Stun still based on Life?

There is no mention at all that Player Stun works like it did in PoE 1. All the help texts just refer to taking a hit and does not mention Life specifically. So, is Player getting stunned still based on Life? Has this ever been officially stated?

Ascesticism exists as a node, so that makes it seem like Life does indeed matter? Even as CI with Base Life just like in Poe 1?

I'm not talking about Stun on Monsters, that is pretty clear.
