Why do you need a spacesuit, and more important, how do you die in space?
To answer this, we must first know why we don't need a special suit for living on Earth. This is because of the atmosphere. The atmosphere controls temperature, causes tons of air pressure (which we need to survive), and protects us from the sun's radiation. So if we go away from the atmosphere, none of this will be there. But you won't die instantly. In fact, you can survive if you've only been outside for around a minute. You would be unprotected from the sun's radiation and because of the vacuum, you would swell up. You wouldn't explode, though. Also because of the vacuum, the boiling point of bodily fluids becomes less than 96.8 degrees Fahrenheit, so your blood would boil. All of this would take a while, but you know what wouldn't? Asphyxiation, or lack of oxygen. In fifteen seconds, you would be unconscious. After 90 seconds, you'd be dead. Holding your breath will actually make it worse, as it can rupture your lungs.
In a vacuum accident in 1965, a person survived similar things as this. He remained conscious for 14 seconds and his last memory before passing out was the spit on his tongue starting to boil.

Hope you learned something and always wear a spacesuit,
