Imagine being in space, without a space suit.

YOU WOULD EXPLODE! - That's what most people say. But, nope. Wrong.

Space is a vacuum. That's why people assume you will explode in space without a suit. What would in actual fact happen is all of the air in your lungs would be pushed out. Breath back in you say? Can't. There isn't any air to breath in. You'd pass out rather quickly due to loss of oxygen. Not good! 

And believe it or not, another concern would be...sunburn. Yes, sunburn! Granted, space has no temperature. But the Sun, as you know, is very hot. Heat from the Sun travels through light. And due to lack of ozone layer protection, you'd be sunburned in seconds.

Moral of the story; don't go into outer space without a space suit!
