Hibernating in a den helps bears survive the hungry winter season.

When a bear hibernates, it barely moves. At the same time, its body temperature drops to 30° C and the functioning of the heart and lungs slows down. Such a state of the body contributes to the economical use of the fat accumulated before hibernation.

The bear does not suck its paw because it wants to eat. It does this to moisten its dry feet and to chew off keratinized and coarsened skin.
