Do bears hibernate?

There are many kinds of bears. Bears that grow in cold areas in the north hibernate, while bears that grow in subtropical areas do not hibernate. Bears are not really hibernating animals. Even when they hibernate, their body temperature only drops by a few degrees. Bears have a long hibernation period, which lasts about 4-5 months. However, if there is any movement during hibernation, they will wake up immediately and be very alert.

Some animals hibernate because of cold weather and lack of food. Animals that need to hibernate will eat a lot of food to provide energy for hibernation before winter comes. When the temperature drops, they will find a warm place, and most animals will choose to hibernate in underground caves. Once hibernating, the basal metabolic rate of animals will become very low, and they can spend the cold winter without extra food intake.
