  In the unfortunate situation that you ended up in space without a spacesuit, you wouldn’t have very long at all until you ran out of breath. No one has ever tested this on humans, for good reason, so the answer isn’t really known!
  
  Chimps have been shown to survive conditions mimicking the vacuum of space for up to about 3 minutes without lasting problems – but we don’t know if this would be the same for humans or not.
