Cryonics is about freezing a deceased person when she dies, with the idea of reviving the patient when the cure to that disease shows up, and the procedure is the one that follows:
- The body is cooled in an ice bath, lowering its temperature bit by bit. The head is the first part of the body that has to be submerged in ice water.
- The patient's blood has to be removed and replaced with antifreeze fluid, to stop harmful ice crystals forming in the body.
- Last, but not least, the body is then stored in a cooling unit. The appropriate program is selected to steadily cool the patient to liquid nitrogen temperature, that’s about - 196°C. Did you know that it could take five and a half days to completely cool the entire body?
Luckily, someone thought about this! The company KrioRus, in Russia, are raising funds to open a plant in Switzerland, one of the few countries that euthanasia is legal. The idea is that the body will be alive when de-frozening begins, which could make it easier than bringing back bodies from the dead, so hope they can make it.
