Bookmark or Share- How Hibernation Works - HowStuffWorksHibernation is a state where animals significantly reduce their metabolic rate, body temperature, heart rate and breathing to conserve energy during periods when food is scarce. Unlike sleep, which is primarily a mental change, hibernation involves drastic physiological changes, and waking a hibernating animal can be fatal due to the high ...
- What is hibernation, how does it work, and which animals do it?Hibernation is a way for many creatures – from butterflies to bats – to survive cold, dark winters without having to forage for food or migrate to somewhere warmer.

- Hibernation: Current Biology - Cell PressHibernation (multiday torpor) and daily torpor in heterothermic mammals and birds are characterized by pronounced temporal reductions in body temperature, energy expenditure, water loss, and other physiological functions and are the most effective means for energy conservation available to endotherms.
- Hibernation - WikipediaHibernation is a seasonal heterothermy characterized by low body-temperature, slow breathing and heart-rate, and low metabolic rate. It is most commonly used to pass through winter months – called overwintering.
