What are the repercussions of being able to finish a short rest in only 10 minutes instead of taking 1 hour?

Currently we are playing a horror adventure in D&D 5e. Due to circumstances (beings locked in a haunted house, rooms changing just when we close the doors, etc.), a 1-hour rest is hardly possible.

Our DM ruled that short rests can be as short as 10 minutes. The obvious result is that we can take it. What are other changes that we, both players and DM, should be aware of?

If it matters, party consists of Lore Bard, Vengeance Paladin, Chaos Sorcerer and Divination Wizard, all level 3.
