Is it possible for your blood to freeze?
Storing blood is vital but actually quite tricky It would be much easier if we could freeze blood and keep it on ice indefinitely Unfortunately blood doesn’t respond well to being frozen It’s not the actual freezing that’s the problem, it’s the thawing afterwards
Does blood freeze in cold weather?
The body responds to cold temperatures by narrowing the blood vessels As the blood is redirected away from the extremities, these parts of the body get colder, and fluid in the tissue can freeze into ice crystals The ice crystals can cause severe cell and tissue damage in the affected area

What is the lowest temperature a human can breathe?
As for cooler temperatures, people on Earth have breathed air as low as -100 degrees F in Antarctica This is possible because some air stays in your lungs each breath and is heated gradually by your blood, so the air in your lungs may still be above freezing even in very cold air
