They do not die from your touch, but the consequences of this can kill them.

Tigers get their food by hunting many animals.
I don't think food is the matter of them hibernating. You should just feed them regular hamster food. Make sure they are warm and not on water or swimming. You can try to hold him to make your hamster to feel warm.
