Human hibernation

There are many research projects currently investigating how to achieve "induced hibernation" in humans. The ability for humans to hibernate would be useful for a number of reasons, such as saving the lives of seriously ill or injured people by temporarily putting them in a state of hibernation until treatment can be given (compare induced coma). NASA is also interested in possibly putting astronauts in hibernation when going on very long space journeys, making it possible one day to visit far away stars.

Erika Nordby, a toddler of 13 months in Edmonton, Alberta, wandered outside her family home on February 23, 2001. The outside temperature was -24C (-11F). When she was found, her heart had stopped beating for two hours and her internal body temperature had fallen to 16C (61F). Other sources say there was a slow pulse of 30 beats per minute but no blood circulation when paramedics arrived. In either event she was clinically dead. She suffered severe frostbite, yet required no amputation and made a full recovery.

In October 2006, a Japanese man, Mitsutaka Uchikoshi, was believed to have been in a "denning"-like state for three weeks. He had fallen asleep on a snowy mountain and claimed he had only woken up after being discovered 23 days later; doctors who treated him believed his internal body temperature had fallen to 22C (71F) during that period.
