Why Do Bears Hibernate?

Answer

Bears hibernate so as to bypass winter which results in the disappearance of their food supply. They usually have a hard time finding food during winter and therefore cuddle up in caves to stay safe from the dangers of this harsh weather.

Bears hibernate because they need to stay warm and healthy during the long winter months. Food is scarce for bears in the winter, so they stock up on their food supply before going into hibernation.
Bears will usually go into hibernation when their food sources are scarce due to the coldness of winter. They will eat and build up body fat so they can sleep through the worst parts of winter.
