How long can an astronaut survive in space without a suit?

Although science is constantly providing new discoveries about space, it remains a place full of unsolved mysteries. And for the same reason, there is always some risk for those who dedicate their lives to space expeditions.

Considering this, the Spacesuits They become a key element for the astronauts succeed in surviving in hostile conditions. They provide them with oxygen, optimal temperatures and protection from the sun’s rays, so they can travel small distances safely in space.

But have you ever wondered how long an astronaut could survive without this crucial piece of clothing?

In a recent interview he gave to the portal Live Science Stefaan de Mey, senior officer at the European Space Agency (ESA) who coordinates the field of human and robotic exploration, said that The human body can resist very little if it is in space without any kind of protection.

“In a very short time, between 10 and 15 seconds, you will lose consciousness from lack of oxygen,” explained the expert.

Even holding your breath would not be a good idea, because in these conditions the oxygen can expand and a tear occurs in the lungs. “This would cause boiling and bubbling in the blood, which would immediately cause an embolism and have a fatal impact on the body,” de Mey added.

The ESA professional points out that a lack of pressure would lead to other serious problems, such as boiling of bodily fluids – urine, saliva or tears.

Radiation, dust particles and even debris lying around outside also pose a great danger to human life. “This is why spacesuits are designed to provide physical protection to astronauts in space,” emphasizes the expert.

As soon as the oxygen in the blood runs out, fainting and subsequently brain death are the impending doom. All this happens in seconds. The only hope would be that the person concerned would be rescued and returned to the spaceship where optimal conditions would be met for resuscitation, but this is not entirely certain.
