For example, when dwarf lemurs hibernate, they reduce their heart rates from over beats per minute to fewer than six, says Blanco. And instead of breathing about every second, they can go up to 10 minutes without taking a breath. This is very different from sleep, which is gentle resting state where unconscious functions are still performed.

Read more about how certain animals cope with cold. There are tropical hibernators that may do so to beat the heat. For example, echidnas in Australia will hibernate after fires , waiting until food resources rebound to resume normal activities. Recent studies have even suggested a third reason: protection. His work has shown that small mammals are five times more likely to die each month when active than when hibernating.

The Arctic ground squirrels Spermophilus parryii Drew works on can take this much further, supercooling to subfreezing temperatures. Not only does adenosine ramp up in winter in ground squirrels, the receptors for the molecule become more sensitive to it.

About 80 percent of their energy is spent intermittently waking and warming up. Read about how groundhogs do this, going into the cycle times during hibernation season.

Some think they need to turn back on their immune systems to fight disease, while others think they may simply awaken so they can sleep. Unfortunately, these arousals may drive hibernating species to extinction as our climate changes; scientists have found that animals stay active longer during arousal periods as ambient temperatures rise, depleting more of the energy they are trying to conserve. One bird and a variety of amphibians, reptiles, and insects also exhibit hibernation-like states.

Most mammalian hibernators are on the smaller side. What Animal Hibernates the Longest? 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. To pull that off, they have to double or even triple their body weight while active.

Also called normothermia or euthermia.

But hibernation isn't the only type of dormancy an animal can experience, and winter isn't the only time of year animals might go to sleep or reduce their activity to survive. Animals might go through hibernation, brumation or estivation aestivation. These terms can be confusing because there are similarities between them all, but there are distinct details that make each process different.

Most people are familiar with the term hibernation, a state of dormancy that endotherms, or warm-blooded animals, do.

The body temperature, heart rate, breathing rate and metabolic rate of the animal slows down during the winter months.

This occurs so the animal can conserve energy and survive during the cold months.
