Cryogenically Freezing Human Body

Credit score: The American Chemical Society

Will cryogenically freezing your self and coming again to life ever be actuality?

If you die, there are loads of issues you are able to do along with your lifeless physique—embalm it, cremate it, donate it to science (the record goes on…), however some folks will select to have their lifeless our bodies, or physique components, frozen till the know-how of the long run has (hopefully) superior sufficient to convey them again to life. This video breaks down the chemistry of cryogenic freezing and if it’s sensible to assume we may ever reanimate a frozen corpse.

Phrases

Cryonics is the low-temperature freezing (often at −196 °C or −320.8 °F or 77.1 Okay) and storage of a human corpse or severed head, with the speculative hope that resurrection could also be doable sooner or later.

Cryopreservation (cryo-preservation or cryo-conservation) is a course of the place organelles, cells, tissues, extracellular matrix, organs, or some other organic constructs prone to harm brought on by unregulated chemical kinetics are preserved by cooling to very low temperatures (sometimes −80 °C utilizing strong carbon dioxide or −196 °C utilizing liquid nitrogen). At low sufficient temperatures, any enzymatic or chemical exercise which could trigger harm to the organic materials in query is successfully stopped.

Cryoprotectants are substances used to defend organic tissue from freezing harm (i.e. that due to ice formation).
