Astronauts in deep space: 5 problems for your health

The space trips or the stays in the space labs that orbit the Earth are not without danger .Surely we all remember the explosion of the Challenger space shuttle in 1986, However, there are other risks that scientists have been evaluating for a future trip to Mars for years. Deep space astronauts: 5 problems for your health.

5 astronaut health problems

1.Cardiac problems

NASA in 2014 concluded, in a study on the heart of astronauts submitted to the microgravity or weightlessness in space, that your heart had become 9.4% more spherical. They think this is due to a loss of muscle mass .This problem is reverts when they return to Earth, but they don't know what would happen on a trip to Mars that is thought to last more than a year.

Astronauts in deep space: 5 problems for your health

The concern of scientists lies in the possibility that this In fact, it can cause cardiac problems to the crew of a ship that travels to deep space and they are studying how to counteract that process.

2.Immune system alterations

Stress, lack of sleep or poor nutrition alter the immune system .In the case of astronauts, according to a NASA study, your immune system is temporarily altered when they are in space.This is especially worrisome when thinking about trips or long-term stays in deep space, since any small infection can become very serious.

3.Renal problems

The bones in space are demineralized and turn into the bloodstream salts such as calcium phosphate .These salts can easily form kidney stones that cause kidney problems in addition to excruciating pain.The formation and expulsion of the stones is aggravated by the fact that astronauts do not drink the recommended two liters of water.

Scientists are currently working on a small ultrasonic machine that would help the expulsion of the stones in the astronaut's kidney.

4.Vision problems

29% of astronauts who spent approximately two weeks in space developed vision problems and among those who spent several months at the International Space Station the figure rose to 60%.Apparently this phenomenon is due to the microgavity to which they are subjected.enden to rise and having a greater amount of cerebrospinal fluid, this expanding expands flattening the eyeballs.The studies focus on finding out what will happen in trips to deep space that last more than 6 months.

5.Learning loss

When astronauts perform any mission in space, however small, they suffer a temporary decrease in hearing and in many cases a small permanent loss.The noise in the cabin was at first so loud that the crew had to wear earplugs in their ears.Although they have been greatly reduced, this can affect hearing, as the increase in intracranial fluid pressure also seems to contribute to that loss.and a greater amount of carbon dioxide or air pollutants.
