What happens after an animal starts hibernating?

The animal goes into hibernation, then wakes up about 180 days later. When its central nervous system sounds the alarm, a hibernator starts to shiver. This uses energy and generates heat. When animals hibernate, their metabolic rate slows way down to conserve energy.

What do animals do when they wake up from hibernation?

Torpor — the state of reduced bodily activity that occurs during hibernation — is not restful. By the time they emerge, hibernating animals are often sleep-deprived: Most expend huge bursts of energy to arouse themselves occasionally in the winter so their body temperatures don't dip too low.

Is hibernation just sleeping?
