The negative effect of entering outer space without a space suit on the human body

what would happen to a human in a vacuum chamber

The body would freeze eventually because heat leaves the body slower than oxygen, therefore a person would die before actually freezing. What does this mean for future space missions?

How long would it take to freeze in space

Although fluids return to a somewhat normal distribution within 12 hours, astronauts often complain of nasal stuffiness and eye abnormalities after extended stays in space [6], which are likely symptoms of the increased intracranial pressure, or pressure within the skull. How long do you have to find a source of both air and air pressure? This could lead to many other risks and problems that are mentioned below. Leblanc states that the saliva on his tongue boiled and then after fourteen seconds LeBlanc became unconscious. Multiple tests have not identified the cause, [92] and several theories have been suggested, including food degradation, and psychological changes such as boredom. Without air in your lungs, blood will stop sending oxygen to your brain. Culture What happens to the unprotected human body in space?

Illustration by Mark Springel, edited by Hannah Somhegyi On Earth, the cardiovascular system works against gravity to prevent blood from pooling in the legs, thus microgravity results in a dramatic redistribution of fluids from the legs to the upper body within only a few moments of weightlessness [5].

In thermodynamic terms, temperature is a function of heat energy in a given amount of matter, and space by definition has no mass.

Oxygen in the rest of your body will also expand. Gut bacteria will start to eat you from the inside out, but not for long, so you will decompose very slowly. The process of natural forms of mummification is explained by Kathryn Meyers Emery here.

The first thing to do if you ever find yourself suddenly expelled into the vacuum of space is exhale.

However, in a microgravity environment there is very little mechanical stress. Your skin is elastic enough to hold you together. LeBlanc's suit sprung a leak, and he remained conscious for about 14 seconds; his last sensation was bubbling on his tongue he was safely revived, as the researchers began repressurising the chamber almost immediately -- after about 15 seconds. Space is such a powerful, uncontrollable, and unexplainable place. You could be floating in space, unchanged, for millions of years. Meanwhile, many of these same films conveniently ignore the slightly more subtle, yet highly relevant hazards of prolonged spaceflight even in an enclosed vessel at normal atmospheric pressure. So the surfaces of your tongue and eyes will boil. Each one sounding more and more painful and torturous than the last.

I'm no biologist, but I'm pretty sure that the valves and tubes that make up your throat were not meant to hold a lungful of atmospheric-pressure air against a pure vacuum. A weakened heart results in low blood pressure and can produce a problem with "orthostatic tolerance", or the body's ability to send enough oxygen to the brain without the astronaut's fainting or becoming dizzy.
