To elaborate on this: by "Hell Effects", he's referring to a special gimmick in the Hells where every couple thousand (?) turns or so, you might randomly suddenly take massive damage, or a bunch of high-level demons will warp in all around you on the spot, or you might be teleported, or a multitude of other nasty occurrences. The Hells are the only place that do that; they're a crazy challenge because in addition to being filled with the most dangerous monsters in Crawl, you are also prohibited from resting to heal,
no matter what, on top of it, thanks to those random "Hell Effects" happening!
But yeah, in the dungeon it's totally okay. In fact, letting more monsters spawn could even be a good thing, 'cause that means there's more things for you to kill and level up on!
The only drawback is that certain deities have a very fast Piety decay rate, such as Makbeb or Vehumet, and they expect you to kill all the time to make up for it. If you overuse resting too much you could expect your Piety to drop a bit when you use those deities, which isn't the end of the world, but don't forget is all.
