Bears do crawl into a cave and essentially sleep away the winter months, but what they're doing is not hibernating, at least not in the true sense. Hibernation is the sleep-like process that involves a depression of metabolic rate, body temperature and breathing rate that many animals enter during the coldest months.
You may wonder, can bears wake up during hibernation? While many people think of hibernation as a deep sleep, that's not exactly correct. In fact, bears can wake up and move around their dens during this time. That's especially true if they sense danger. Bears have been known to even leave their dens if they become damaged.
Similarly one may ask, how long do bears sleep while hibernating? Bears can sleep more than 100 days without eating, drinking, or passing waste! Bears can actually turn their pee into protein.
Besides above, what happens if a bear wakes up in the middle of hibernation? For hibernating animals, an early wake-up call isn't just an inconvenience—it can be downright lethal. Waking up from hibernation requires a lot of energy, depleting reserves that are key to surviving the winter. It's not just bears that are in danger if they wake up from hibernation at the wrong time.
Likewise, can a human go into hibernation? Human hibernation doesn't exist for many reasons, but the reason why is not quite as immediately obvious as you might think. Hibernation is a response to cold weather and reduced food availability.
What do black bears eat when they come out of hibernation?

What is the difference between hibernation and torpor?

What happens to bears when they hibernate?
Hibernating bears enter a shallow torpor with a decrease in body temperature of only 10 degrees. It's metabolism and hear rate slows down. But it doesn't need to eat, drink or pass waste. In order to survive, fat in the bear's body breaks down into water and calories for the body to use.
