I find that generally if it's not feasible to rest for 8 hours it's not feasible to rest for 1 hour either.
The way I see it, long rest in the wilderness is 8 times more dangerous than a short rest.
I offered my group the opportunity to adopt a house rule in our game that just started, wherein short rests would only be 10 minutes long, but long rests would take a full 24 hours - but while they considered it, they ultimately rejected it. While they knew resting for an hour could be dangerous, having to find a place to hole up for 24 hours or return to town in order to get a long rest was a lot more onerous and potentially dangerous than 8 hours.
