Marvel Reveals The Scientific Explanation of How Captain America Survived in The Ice all Those Years in the MCU

A lot of fans have wondered how exactly Steve Rogers a.k.a. Captain America survived being frozen in ice for nearly 70 years in the MCU. Some fans assumed that it's an effect of the Super Soldier Serum, but it's hard for others to believe that a man could survive in a frozen state for all those years only to be thawed out and return to normal regardless of the superhuman enhancements. 

Well, Marvel has provided a scientific explanation of how it is possible and it popped up at the Avengers S.T.A.T.I.O.N. in Las Vegas of all places. A photo was posted on Reddit that provided a look at the explanation, and as you'll see, it points to a biological phenomenon that's usually only seen in animals. Here's what it says:

"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."

So thanks to the crazy high amount of glucose in Cap's blood it wouldn't freeze. It's a form of hibernation and while this has never been seen in human before, this is obviously a result of the Super Soldier Serum that was injected into Cap. 

Then, of course, these are comic book movies and a lot of the things that we see in these films are completely impossible, which is what makes them so fun to watch! But it's kind of cool to get a little nugget of information like this every once in a while.
