Hibernation is a state of minimal activity and metabolic depression undergone by some animal species. Hibernation 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.
Humans still don’t need to hibernate, Weiss said, nor can we afford to due to our social and occupational obligations. “But we can make adjustments to perform in a better way, to rest in a ...
A new study analyzes the blood cells of bats (of both the hibernating and non-hibernating varieties) and humans to understand the role these cells play in keeping mammals alive during prolonged ...
Hibernation is a mechanism used by many mammals to reduce energy expenditure and survive food shortages over the winter. Hibernation may be predictive or consequential. An animal prepares for hibernation by building up a thick layer of body fat during late summer and autumn that will provide it with energy during the dormant period.
During the first year, the squirrels began hibernation in late October. They started hibernating in mid August and early April respectively for the following two years, displaying a circannual rhythm with a period of about 10 months. [5] An annual rhythm has been observed in humans diagnosed with obsessive compulsive tic disorder (OCTD).
At least six major areas of cryobiology can be identified: 1) study of cold-adaptation of microorganisms, plants (cold hardiness), and animals, both invertebrates and vertebrates (including hibernation), 2) cryopreservation of cells, tissues, gametes, and embryos of animal and human origin for (medical) purposes of long-term storage by cooling to temperatures below the freezing point of water.
Heterothermy or heterothermia (from Greek ἕτερος heteros "other" and θέρμη thermē "heat") is a physiological term for animals that vary between self-regulating their body temperature, and allowing the surrounding environment to affect it.
Hibernation is voluntary, whereas torpor is involuntary, like breathing. There are many animals that do go into full hibernation. True hibernators include squirrels , mice, bats, and turtles .
