The primary focus of research for human hibernation is to reach a state of torpor , defined as a gradual physiological inhibition to reduce oxygen demand and obtain energy conservation by hypometabolic behaviors altering biochemical processes.

This involves lowering the body's temperature below 34 °C (93 °F), which is the current standard for therapeutic hypothermia . In June 2005, scientists at the University of Pittsburgh 's Safar Center for Resuscitation Research announced they had managed to place dogs in suspended animation and bring them back to life, most of them without brain damage , by draining

390-521: Is different from Wikidata All article disambiguation pages All disambiguation pages Suspended animation Suspended animation is the temporary (short- or long-term) slowing or stopping of biological function so that physiological capabilities are preserved. States of suspended animation are common in micro-organisms and some plant tissue, such as seeds. Many animals, including large ones, may undergo hibernation , and most plants have periods of dormancy . This article focuses primarily on
416-860: Is required. Suspended animation is understood as the pausing of life processes by external or internal means without terminating life itself. Breathing, heartbeat and other involuntary functions may still occur, but they can only be detected by artificial means. For this reason, this procedure has been associated with a lethargic state in nature when animals or plants appear, over a period, to be dead but then can wake up or prevail without suffering any harm. This has been termed in different contexts hibernation , dormancy or anabiosis (the latter in some aquatic invertebrates and plants in scarcity conditions). In July 2020, marine biologists reported that aerobic microorganisms (mainly), in "quasi-suspended animation", were found in organically-poor sediments , up to 101.5 million years old, 68.9 metres (226 feet) below
442-400: The blood out of the dogs' bodies and injecting a low temperature solution into their circulatory systems , which in turn keeps the bodies alive in stasis. After three hours of being clinically dead , the dogs' blood was returned to their circulatory systems, and the animals were revived by delivering an electric shock to their hearts. The heart started pumping the blood around the body, and
468-1006: The sea floor in the South Pacific Gyre (SPG) ("the deadest spot in the ocean"), and could be the longest-living life forms ever found. This condition of apparent death or interruption of vital signs in humans may be similar to a medical interpretation of suspended animation. It is only possible to recover signs of life if the brain and other vital organs suffer no cell deterioration, necrosis or molecular death principally caused by oxygen deprivation or excess temperature (especially high temperature). Some examples of people that have returned from this apparent interruption of life lasting over half an hour, two hours, eight hours or more while adhering to these specific conditions for oxygen and temperature have been reported and analysed in depth, but these cases are considered rare and unusual phenomena. The brain begins to die after five minutes without oxygen; nervous tissues die intermediately when
494-442: The 1970s, induced hypothermia has been performed for some open-heart surgeries as an alternative to heart-lung machines . Hypothermia, however, provides only a limited amount of time in which to operate and there is a risk of tissue and brain damage for prolonged periods. There are many research projects currently investigating how to achieve "induced hibernation " in humans. This ability to hibernate humans would be useful for
520-570: The dogs were brought back to life. On 20 January 2006, doctors from the Massachusetts General Hospital in Boston announced they had placed pigs in suspended animation with a similar technique. The pigs were anaesthetized and major blood loss was induced, along with simulated - via scalpel - severe injuries (e.g. a punctured aorta as might happen in a car accident or shooting). After the pigs lost about half their blood
546-518: The early human population whose remains have been retrieved at the Archaeological site of Atapuerca . In a paper published in the journal L'Anthropologie , researchers Juan-Luis Arsuaga and Antonis Bartsiokas point out that "primitive mammals and primates" like bush babies and lorises hibernate, which suggests that "the genetic basis and physiology for such a hypometabolism could be preserved in many mammalian species, including humans".

598-449: The minimum conditions in an environment extremely close to death and return to a normal living state. An example of such a case is Anna Bågenholm , a Swedish radiologist who allegedly survived 80 minutes under ice in a frozen lake in a state of cardiac arrest with no brain damage in 1999. Other cases of hypothermia where people survived without damage are: It has been suggested that bone lesions provide evidence of hibernation among
624-537: The potential of large animals, especially humans, to undergo suspended animation. In animals, suspended animation may be either hypometabolic or ametabolic in nature. It may be induced by either endogenous, natural or artificial biological, chemical or physical means. In its natural form, it may be spontaneously reversible as in the case of species demonstrating hypometabolic states of hibernation . When applied with therapeutic intent, as in deep hypothermic circulatory arrest (DHCA), usually technologically mediated revival
650-519: The remaining blood was replaced with a chilled saline solution. As the body temperature reached 10 °C (50 °F) the damaged blood vessels were repaired and the blood was returned. The method was tested 200 times with a 90% success rate. The laboratory of Mark Roth at the Fred Hutchinson Cancer Research Center and institutes such as Suspended Animation, Inc are trying to implement suspended animation as
676-612: Was demonstrated that physiological and biochemical events could inhibit endogenous thermoregulation before the onset of hypothermia in a challenging process known as "estivation". This is indispensable to survive harsh environmental conditions, as seen in some amphibians and reptiles. Lowering the temperature of a substance reduces its chemical activity by the Arrhenius equation . This includes life processes such as metabolism. Cryonics could eventually provide long-term suspended animation. Emergency Preservation and Resuscitation (EPR)
