In space, there is no atmosphere to equalize pressure, so any air or gas inside an astronaut's body expands and causes the body to "blow up" or swell. This is known as decompression sickness or the "bends," and it can be dangerous or even fatal. Proper pressurized spacesuits are used to protect astronauts when in space to prevent this from happening.
