They hibernate because there is not enough food for them in the winter.
Why Do Animals Hibernate?
The word hibernate came from the Latin word which meant "winter sleep". The sleep of a true hibernator is almost like death and it quite unlike ordinary sleep. While an animal is hibernating, all of its life activities nearly stop. The temperature of its body decreases until it's only a little warmer than the air of its den.
Because of this, the animals burn the food stored in their bodies very, very slowly. Since they burn less fuel, they need less oxygen and as a result their breathing is slower and their hearts beat only faintly. If the temperature in the den becomes very low, the hibernating animal wake up, digs itself a little deeper and back to sleep once more.
After the spring comes, the animals are awakened by the change in temperature, moisture and clearly by hunger. Some cold-blooded animals also hibernated. One of them is snake. Snakes crawl into cracks in the rocks or in the mud at the bottom of ponds.
