100 Mind-Blowing Eardrums Facts
You could survive for a couple of minutes in a leaky spacesuit. Although films such as Total Recall show instant explosions and rapidly puffed-up spacesuits, the effects of being exposed to space are slightly less dramatic. Although it would be unpleasant, you could survive for a couple of minutes. After around 10 seconds, you would lose consciousness. The lower pressure of the vacuum would cause your blood to boil, along with other body fluids (the moisture on your tongue, for example) – but this boiling alone would not be fatal due to the pressure maintained by our blood vessels themselves. Gas bubbles would form in your bodily fluids, causing your body to swell up and bloat. The low humidity of space would cause you to cool down rapidly, and your eyes may freeze over. Within one to two minutes, the lack of oxygen would be deadly. The stress of the situation may make these symptoms worse – you would become oxygen-deprived more quickly. A rapid decompression would cause damage to your lungs, eardrums and sinuses, along with bruising and bleeding from soft tissues.
