What Happens To A Human Body in Space?

What Happens To A Human Body in Space?

March 3, 2021

A lack of gravity is termed as the state of Microgravity. It is this key aspect that differentiates Earth from outer space.

Suitable life conditions on earth facilitate life. The omission of the most basic elements like air or water in the outer space makes living conditions unsuitable for facilitating human life.  It is true that humans cannot exist in a realm with no air and almost zero pressure without some or the other form of protection.

If a human body is exposed to space, in 15 seconds you will start to lose consciousness.

Chronology of what would have if human body is exposed to space?

According to research, the first thing you would notice is the lack of air. This won’t lead to losing consciousness right away; it may take up to 15 seconds. In these 15 seconds, the human body uses up the remaining oxygen reserves from your bloodstream. human body in space

Now, all exposed liquid on your body will begin to vaporise. As a result of which, the surfaces of your tongue and eyes will boil. Without oxygen in your lungs, blood will stop sending it to your brain, and we all know how that ends.

Space makes your body have an Ebullism

When an individual is launched into outer space, he leaves the innate biological surroundings that nurture his biological and geographical needs. The vacuum of space poses the problem of not having a normal atmosphere.

Upon sudden exposure to vacuum, expansion of air in a person’s lungs is likely to cause lung rupture and death. This will be the likely fate unless that air is immediately exhaled.  human body in space

So, if a person is unprotected, then he or she might just explode like a bomb? The reality in this situation is a little less dramatic than that. However, they won’t explode, but it isn’t as if they won’t inflate. The nitrogen near the surface of the skin or in the bloodstream will form bubbles. These bubbles increase in size, puff humans out to twice their size, beginning at hands, feet and moving it further. This is called an ebullism.

What ultimately dooms a human in space is their own traitorous circulatory system. Low on oxygen, the think-box goes into shutdown mode to conserve energy. A human will lose consciousness in about 15 seconds after leaving the safety of the airlock. However, they are not a corpse yet. If some good (space) Samaritan pulls the exposed human back to safety within a minute or two, it shall be all right. 

So, there’s the ebullism, flash-frozen skin and a bonus nasty sunburn from all that raw, unfiltered UV radiation. But that’s workable, albeit a bit uncomfortable. human body in space

Can a body perish in Space?

If you die in space wearing spacesuit, your body will decompose as it contains oxygen.

The cardiovascular system is massively influenced by gravity. In space, the heart becomes much smaller, and the blood volume decreases; the longer the space flight, the more problematic the changes. human body in space

80% of astronauts experience low blood pressure once they return. As a result, they are prohibited from driving three weeks after landing.

If a human body was sealed in a spacesuit, it would decompose as long as it has an oxygen supply. The body would last for a considerably long time without air since there is nothing to catalyse degradation and weathering. If you die in space, your body will not decompose since there is no oxygen.

Your corpse could float in space for millions of years, and it’s not bad totally; astronauts get taller in space due to the spine not being compressed by Earth’s gravity. Nevertheless, the lack of air and pressure will kill you slowly, just like sweet poison. So, if you’re smart, you won’t expose your pristine body to the cosmic mysteries!
