A) Bears hibernate during winter, but aren't sleeping the whole time. Hibernation for bears simply means they don't need to eat or drink, and rarely urinate or defecate (or not at all). There is strong evolutionary pressure for bears to stay in their dens during winter, if there is little or no food available.
You may wonder, what happens if you wake up a hibernating bear? 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.
Similarly one may ask, how long do bears sleep in hibernation? Hibernation can last anywhere from 4-7 months, triggered by seasonal food shortages, cold temperatures and snow cover. When the going gets tough, the tough get… sleepy. Time spent hibernating depends on environmental conditions and the sex and reproductive status of a bear.
Besides above, do bears wake up while hibernating? Most animals that hibernate, like squirrels, wake up gradually. However, bears can wake up instantly from their deep sleep. Due to these differences, some people argue that bears do not truly hibernate. Instead, they use distinct terms for what bears do such as winter sleep, carnivoran lethargy, torpor, and dormancy.
Likewise, is it possible for a human to hibernate? 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 animal hibernates the longest?
What Animal Hibernates the Longest? It's harder than you'd think to award a prize for longest duration of hibernation. The obvious choice would be the edible dormice (Glis glis) Ruf works with—they can stay dormant for more than 11 months at a time in the wild.
What do black bears eat when they come out of hibernation?

Torpor involves physiological changes related especially to body temperature, metabolism, and water balance. Hibernation is when an organism spends the winter in a state of dormancy; it is long-term multiday torpor for survival of cold conditions.
Can animals wake up during hibernation?
