Dr Gregory Brammer
As an expert physician who has worked in emergency care for many years, Dr. Gregory Brammer knows a thing or two about resuscitation.
Most scientific sources agree that the colder it is, the higher the chances of reviving someone will be, even well after the cardiac arrest has occurred. There are various remarkable cases often involving people who fell into ice-cold water, only to be revived 30, 40 or even 80 minutes after the accident. The phenomenon is medically proven, and has everything to do with metabolism.
The body and its cells need oxygen to survive. It is an intricate system built on energy input and transformation at the cellular level. Normally, the cells need a certain amount of energy. However, when the body is immersed in cold water, it defends itself by significantly reducing its own metabolism, and therefore its energy needs. That is why these stories are possible.
Cryonics Doesn’t Work (So Far)
If low temperatures improve the chances of resuscitation, could cryonics actually work? The answer is sadly no, or at least not at this moment. Science does not have a method to reverse cell death yet, and there may not be one. They can freeze a recently deceased person in a very efficient way, one that does not involve the formation of ice crystals that would significantly damage human tissue, but the rest is a huge question mark at best. Medical science does not seem to be particularly close to the answer, if one even exists.
Dr. Gregory Brammer hopes that one day science will have more answers to these burning questions.
