During hibernation, an animal's body temperature, heart rate, breathing, and other metabolic activities slow down significantly in order to conserve energy. While resources are scarce, hibernation allows animals like bears, chipmunks, and bats to use their stored energy much more slowly.

Why does hibernation happen?
Certain animals hibernate because food supplies become scarce during the winter months. ... Brown fat provides extra body heat as well as needed energy when the animal wakes up. Some animals also store food in their dens to consume during brief periods of wakefulness. Hibernation is nothing like a regular night's sleep.
Why does hibernation happen in winter?
What is hibernation? Hibernation, by definition, is when animals “sleep” through the winter season. During hibernation, the animal's body temperature, heart rate and breathing rate all drop to significantly lower levels. Animals do this to survive the winter because the weather is cold and food is scarce.
How does hibernation actually work?
How does hibernation work? During hibernation, the hibernating animal's metabolism, heart rate, and breath rate slow way down. ... Meanwhile, the hibernating animal becomes completely immobile, falling into a coma-like state. During hibernation, the animal's body doesn't need nearly as much energy to stay alive.
What is hibernation and why is it important?
Hibernation is an important adaptation to harsh climates, because when food is scarce, an animal may use up more energy maintaining its body temperature and in foraging for food than it would receive from consuming the food. ... Many animals sleep more often when food is scarce, but only a few truly hibernate.
Can humans hibernate?
They suggest these early humans found themselves “in metabolic states that helped them to survive for long periods of time in frigid conditions with limited supplies of food and enough stores of body fat”. They hibernated and this is recorded as disruptions in bone development.
Is hibernation just sleeping?
Despite what you may have heard, species that hibernate don't “sleep” during the winter. Hibernation is an extended form of torpor, a state where metabolism is depressed to less than five percent of normal.
Do animals poop when they hibernate?
Even those hibernators that don't eat or drink anything at all sometimes defecate and urinate during hibernation (metabolizing stores of fat does produce waste), but these animals expel only a tiny amount during hibernation. ... However, instead of urinating and defecating, hibernating bears recycle that waste.
Are bears awake during hibernation?
We have heard since childhood that bears “sleep” through the winter, but in fact they are awake and in a reduced metabolic state.
Do snakes hibernate?
Unlike mammals, snakes don't go into full hibernation. Instead, snakes enter a similar state called brumation.
Do bears give birth during hibernation?
Bears give birth in February, during hibernation, and the offspring nurse and grow until the momma bear wakes up. ... But researchers were able to observe that the mother didn't lower her body temperature at all until after the birth, suggesting that warmth is important for baby bear development.
How do you speak hibernation?
Break 'hibernation' down into sounds: [HY] + [BUH] + [NAY] + [SHUHN] - say it out loud and exaggerate the sounds until you can consistently produce them. Record yourself saying 'hibernation' in full sentences, then watch yourself and listen.
How do animals know when to hibernate?
Hibernators have an internal clock, a series of chemical reactions controlled by the hypothalamus of the animal's brain. External signals set the clock. ... The shorter days and cooling temperatures of autumn set its clock to time zero. The animal goes into hibernation, then wakes up about 180 days later.
Do animals actually hibernate?
Animals enter hibernation to conserve their energy during times of short food supply and inhospitable weather (5). Many different animals hibernate, including mammals (6), birds (7), and even fish (8). The hibernation process might surprise you, because it's different from what most people have been taught about it.
What happens if you wake up a bear during hibernation?
Their body temperature drops. Their breathing and heart rates slow. Their body also starts to burn calories slower. These changes allow the bear to survive longer on its own body fat.
Can hibernation stop aging?
Hibernation slows down the shortening of telomeres, and could explain why some rodents live longer than other animals, say researchers. ... But while this suggests hibernation slows the rate of ageing, the longer life span could be due to some other factor, says Turbill.
Are humans meant to sleep more in winter?
In fact, if you sleep too much, chances are you'll feel even more sluggish during the day. We do not actually need any more sleep in winter than we do in summer – aim for about 8 hours of shut-eye a night, and try to go to bed and get up at the same time every day.
How did early humans stay warm?
During medieval times, men, especially outlaws, would keep warm in the winter by wearing a linen shirt with underclothes, mittens made of wool or leather and woolen coats with a hood over a tight cap called a coif. Even if the men lived outside and it rained, they would wear their wet woolen clothing to stay cozy.
