Captain America’s Frozen State Explained: Hibernation

Marvel

Have you ever wondered  how Captain America (Steve Rogers) survived being frozen for a lengthy time in the Marvel Cinematic Universe? The superhero was frozen for 70 years and he lived on. There have been speculations about his survival being due to the Super Soldier Serum, but this is questionable because despite his superhuman qualities. It would be really unimaginable for someone to be frozen for that long without thawed out, and more over, return to normal.

We can stop speculating now, because marvel has provided a scientific explanation of how this could ever be possible. This explanation made itself known at the Avengers S.T.A.T.I.O.N in Las Vegas. A Reddit user posted a photo which provided a look at the explanation, and it points out to a biological phenomenon usually seen in animals. The photo stated:

“Physical examination of Capt. Rogers revealed that while thickened, his blood’s water was not frozen. Blood tests revealed that his blood contained excessive amounts of glucose as a result of his liver processing his glycogen stores, thus lowering the freezing temperature of blood-borne water and creating a ‘cryoprotectant’. This process is similar to that of Water-Bears (Tardigrades) and hibernating Wood Frogs who metabolize glycogen in their liver to circulate copious amounts through their body to reduce the osmotic shrinkage of cells and stop from freezing. This, however, has never been seen before in humans.”

This phenomenon can there be credited to the amount of glucose in the captain’s blood. He was just hibernating; even though human beings are incapable of doing so, the captain is not any ordinary human. Moreover, he had the Super Soldier Serum injected into him.

Even though it is impossible for this to happen in the world we live in, it is possible in the MCU. Perhaps that is what makes us love it so much.
