Is it possible to freeze a human body?

(Inside Science) — Early in the 1960s, a group of enthusiasts advanced the concept of freezing humans as soon as they die, in hopes of reviving them after the arrival of medical advances able to cure the conditions that killed them. The idea went into practice for the first time 50 years ago.

How long does it take to cryogenically freeze someone?

Lots of paperwork must take place long before death if the cryogenic process is to take place. Clients must complete all the necessary documentation and make sure funding is in place well ahead of time. The freezing process must begin within 2-15 minutes after the person has been declared legally dead.

Is cryonics the same as freezing?

Although it’s true that the process of cryonics involves lowering your body’s temperature substantially, it’s not at all the same process as simply throwing something in the freezer. The chemicals placed in your cells (through a process called vitrification) actually protect tissue and organs from freezing.

How do cryopreservationists preserve frozen bodies?

To prevent ice crystals from damaging cell walls in the frozen state, cryopreservationists replace the body’s blood supply with mixtures of antifreeze compounds and organ preservatives — a technique developed to preserve frozen eggs for fertility treatments. Another emerging approach accounts for the separation of Ted Williams’ head and body.

Is it possible to be cryogenically frozen after death?

A teenager who tragically died of cancer recently has become the latest among a tiny but growing number of people to be cryogenically frozen after death. These individuals hoped that advances in science would one day allow them to be woken up and cured of the conditions that killed them.

Can we freeze the dead and revive them?

An experiment half a century ago created an industry that specializes in freezing the dead. Many scientists think the chance of reviving them is slim.

Can we freeze our brains for the future?

Based on studies of roundworms, promoters of cryonics argue that freezing can preserve the contents of individuals’ brains even if their bodies can’t be revived. That opens the possibility of downloading cryopreserved personalities into a robotic future body.
