A hibernation chamber is a device that can shut down the life processes of a living being and put it into a state of suspended animation. In this condition, the subject does not age, deteriorate, or require food, air or any other type of sustenance.
After a subject is placed in the hibernation chamber, it is filled with a liquid that contains nanomachines and preservative biochemicals. While the biochemicals sustain the subject’s body at a macro level, the nanomachines work a the cellular level, essentially building ‘protective scaffolding’ around each individual cell.
It takes five hours to put a subject in stasis and eight hours to awaken one, both procedures that should be supervised by a physician. Upon being awakened, most subjects will experience some degree of confusion and sometimes amnesia for a period of several hours to several days.
Hibernation is a very safe process, and a subject can theoretically be kept in stasis almost indefinitely. However, a few subjects that have been awakened after very long periods (ten years or more) of stasis have shown signs of serious psychological conditions. It is not known whether such trauma is a result of the stasis period itself, or rather of the stress resulting from either the fact of ‘losing’ a significant number of years or perhaps the events that made the hibernation necessary in the first place (e.g. a deep-space disaster).
