The popular YouTube personality Dalas Review has done it again. Just a year ago, he became a trending topic after publishing a post about his intentions to invest in a laboratory dedicated to studying methods to prevent aging. Now, a year later, he is back on Twitter, bringing up the topic of cryogenization once more. By doing so, he is encouraging people to talk more about it, increasing awareness and improving the processes involved in this system.

But, what exactly is cryogenization? Does it exist today or is it just a myth? The concept of cryogenization has often been portrayed in science fiction movies, especially those set in space, where astronauts have to induce a deep sleep that lasts for years in order to reach a distant location in the universe.

What is Cryogenization?

The term cryogenization comes from the Greek word “kryos,” meaning cold. Cryogenization is the process of freezing biological materials at extremely low temperatures with the aim of reviving them in the future. In simple terms, it involves freezing a human body under specific temperature conditions in order to reanimate it later, preserving it during that period.

This science, which currently seems more like fiction than reality, is based on the preservation of food through cold storage, a technique that has been used throughout history. However, it was the cryogenization of human embryos that served as a precedent for the cryogenization of whole bodies.

People describe near-death experiences in remarkably similar ways, which has convinced some researchers that there is life after death.

The process of cryogenization is quite complex. It must be initiated within a couple of minutes after a person’s death. The procedure can only be carried out once the patient’s heart has stopped beating but before brain death is declared.

Afterwards, the patient’s blood is extracted and replaced with a cryoprotective fluid. This substance aims to prevent the formation of ice crystals inside the body. Once this fluid is in circulation, the cooling process begins. Finally, the body is submerged in a cryogenic chamber at a temperature around 200 degrees below zero.

Can Someone Undergo this Process?

Currently, cryogenization is not reversible in animals or humans. In other words, there is no way for a person to survive once frozen. However, it is possible in some microscopic organisms, and they have even demonstrated memory persistence.

The first person to be frozen with the intention of being revived was James Bedford, a psychology professor who was rudimentarily cryopreserved in 1967 by the Cryonics Society of California (CSC). Over time, it was discovered that he was not the only attempt, as several bodies that had been thawed were found.

As strange as it may seem, this practice is still being carried out today, although it bears little resemblance to what has been depicted in movies. At present, it is nothing more than a utopia, but in many years, the required thawing phase might be possible, and some companies believe in its potential.

There are already companies, such as Alcor Life Extension Foundation, dedicated to cryonics. They have patients who hope to be cured using future medical technology. More and more people are convinced of this process, although not everyone can afford it, as it costs thousands of euros.
