During hibernation, an animal's body temperature, heart rate, breathing, and other metabolic activities slow down significantly in order to conserve energy . While resources are scarce, hibernation allows animals like bears, chipmunks, and bats to use their stored energy much more slowly.
What do animals need to hibernate?
In order to hibernate successfully, animals need to gorge themselves on food as much as possible . By eating more than usual, the animal builds up extra layers of fat. During hibernation, the animal's body will feed on this fat to keep itself alive. Extra fat also helps the animal stay warm when they're immobile.

Why can't humans hibernate?
Humans are not adapted to hibernation . Hibernation requires many specific adaptions – the ability to slow heart rate, the ability to lower metabolism but also the need to hibernate. We have no need – we did not evolve in climates that required us to hibernate.
Why do animals come back after going to warm places in winter?
I learned that animals hibernate to especially get food or reproduct themselves, for this to happen they need to do a subprocess called the migration where they move from where they are to the south to be warm and avoid the winter.
