It's all dependent on how restrictive the armor is.*
I've napped in Roman style Lorica Segmentata, a (clamshell) Breastplate, Hard Boiled Leather, Chain Hauberk, and Scale Hauberk.
The worst was the Breastplate (followed by the Hard Leather), very hard to get comfy in, ended up slept sitting up - so if you can do that you're fine-ish. I was a bit knackered, but not really slowed down. I imagine having to sleep that way for multiple days would be rough.
The other armors were okayish, once I removed the gorget (neck armor) and nut cup. Something I could get used to, but I really wouldn't want to.
* Based on my personal experience, if you're already making sleeping in "the rough" difficult (ie making Endurance checks to sleep well), then Celebrim's system seems fair. As for armor "sucking the heat from you", not so. Most heavy metal armors have a thick padded cloth worn under it, otherwise the spots it rubs on your body would get raw fast. This thick padded Arming Coat is pretty damn good at keeping the heat in.
Some armors skip the Arming Coat (Lorica Segmentata) because it's banded armor over thick leather. So it too is a bit warm (though the open and breezy leather skirt helps keep you cooler).
This was all in Florida, both in Summer (high 90's fall over dead from heat stroke) and mid-Winter (dropped to below freezing) weathers. In the Winter I'd favor heavier armor, it keeps you warmer. In Summer I'd favor "Barbarian" style semi-nude combat. With our humidity and heat... any armor will kill you faster than the enemy.
So no. I wouldn't bother making my PCs take off their armor. If I wanted to be "semi-realistic" I'd adopt something similar to Celebrim's Endurance checks. Which in 5e most Fighter type will be making easily.
