Hamsters in cold weather

I live in a place that has no heat during winter. The temperature would go down to about 7-8 degrees at the lowest. Would hamsters sleep a lot in this weather? Would they play less on the wheel and mostly sleep during the night? I just want to get prepared...Thanks.

hamsters need heat or else they will go into hiberbnation. and when they go into hibernation they will appear as if they are dead so ya just to let you know. but you should have heat for your hamster because it is wrong not to have heat for them.

hibernation is not good for hamsters because during this time they don't eat they don't drink so they can basically starve to death and become badly dehydrated during this time. and i have looked every where for the temp that they go into hibernation but all the sites i visited said that when the temperature drops below normal they can go into hibernation. now if i were you i would try and keep the room that the hamster is in warm for him. just a question but if your house has no heat or anything to keep him warm how do you stay warm yourself? i think maybe you should look into getting some kind of heat. i hope i gave u the info you needed and i hope your hamsters does not go into hibernation.
