During "true hibernation," the animal's body temperature drops, and its rate of breathing slows down. These hibernating animals are very difficult to awaken. ... In older scientific literature, hibernation used to refer only to low-body-temperature winter dormancy, but now that much more is known about this dormancy phase,

Hibernation is a state of inactivity and metabolic depression in animals, characterized by lower body temperature, slower breathing, and lower metabolic rate, to conserve energy, especially during winter. Hibernation may last several days or weeks depending on species, ambient temperature, and time of year.

Popular article, based on PBS series, about hibernation biology of Ursus americanus. ... By December, when the bear was deep in hibernation, its sleeping heart rate had slowed to as few as eight beats a minute. Black bears keep their heads and torsos warm enough that they can wake if disturbed, though some may take awhile to do so.

Hibernation is different from sleep. With normal sleep, the animal moves a little, has an active brain, and can wake up very quickly. ... There are different kinds of hibernation. A "True" hibernator appears to be dead because the animal's heart rate slows down and the body temperature drops to almost the same temperature...

Hibernation is a dormant sleep-like state. By going into hibernation the bears bypass winter when their food supply, nuts and berries, disappears. Animals like the bear would find it extremely difficult to find enough food during winter, and therefore go into hibernation.
