Not really. Each hedgehog is different. I've had ones that would attempt it even at 77 or 78F yet others were fine at 70F. I've had a couple of girls that needed a heating pad even with a 78F room.
Over the years, most people have found 75F to be the temperature that most hedgehogs are seem to do best. Sometimes even if they don't attempt hibernation or don't feel cool at a lower temp, they are much more active and happy when it's warmer.
