Does Cryonics Work?
Currently, there hasn’t been any case of an individual who has been successfully revived from cryonics. Though some body tissues can be preserved successfully, it is basically believed that this procedure might be too complicated to succeed. The rates of freezing should be carefully controlled to minimize the decay and death of cells. The problem is that ice crystals would form, which eventually damages these cells. A mixture is injected to prevent ice crystals from being formed, but it is still not clear whether it would quickly reach all cells enough.
To revive a cryopreserved body, it means we need to repair all tissues damaged by the lack of oxygen, the toxicity of cryoprotectants, and ice crystals. Also, it is necessary to treat the underlying conditions that result in death. Currently, these challenges seem impossible. Whether technological advances in the future might help resolve these problems is still unknown. And even when cryonics is technologically feasible, there are also many other problems, such as cultural, legal, and psychological. [4]
