What would happen to an astronaut into space without a space suit?

In essence, a spacesuit Hatching the human body and recreates a land as environment so that astronauts can work in a environment relatively normal when in space.

Provides such things as a pressurized environment very similar to an airplane, and this keeps all the various fluids in your body into a liquid state. Without that actually would boil the fluids of the body-space is a rather hostile to humans!

It is essential that the spacesuits provide pure oxygen to breathe, just like when you could undergo a procedure at the hospital. Should match exactly what breath oxygen on Earth in a space suit would cause low levels of oxygen in the lungs and blood because the pressure in spacesuits is so low.

Temperate inside the suit is regulated in order to cope with the huge fluctuations experienced by astronauts in space. The clothes are heavily insulated with various fabrics such as Neoprene and Dacron. There is also an outer layer that is designed to reflect sunlight.

Due to spacesuits are designed with multiple layers of fabric, is protected by another space danger know as micrometeorites that can tear and damage suit.

So what would happen to your body without a spacesuit in space?

It would become unconscious within 15 seconds due to there is oxygen. All fluids in your body would boil and due to the fact that there is no air pressure would freeze shortly after. Therefore boiling fluids would expand all your major organs such as hearts and lungs. Finally they also experience dangerous levels of radiation and the solar wind.
