They do not die from your touch, but the consequences of this can kill them. As with all hibernating animals, they do this mainly in order to preserve energy resources when there is little food around. If you wake up an hibernating animal, then it will most likely extend its energy on trying to find food and if it can not find food then it will most likely die.
Bats will usually sense when it is time for them to stop hibernating, and they will most likely go back to sleep.

I personally think that hibernating hedgehogs live in their very own nest, howvere I am not 100% sure with this !
