Human Body Not Designed for Space Researchers Say

Dream of travelling to the moon? You may want to think otherwise because the human body is not designed for space travel, researchers say. Researchers are looking into growing concerns over the long-term health effects space can have on astronauts. According to research, astronauts have returned from space with poorer eyesight, bone and muscle loss, and may be at a greater risk for cancer due to radiation exposure.

Since the first American was launched into space in 1961, there are still many unknowns when it comes to how space affects health, and some problems have only recently been discovered per BUSTLE. With the human body containing about 60 percent water, this can be affected when in space as your fluids float into your chest and head, causing increased pressure and swelling.

Some astronauts have even reported trouble sleeping and eating. In 2009, NASA astronaut and physician Dr. Michael R. Barratt reported having difficulty seeing objects close up while he was on the International Space Station. Another doctor and crew member on board performed an eye exam on Barratt and found his vision shifted towards farsightedness. His eye had become squeezed, with abnormal bends in the optical nerves and blemishes on the retina.

Retired NASA astronaut Mark Kelly, will aid in a study that monitors the health of his brother and fellow astronaut Scott Kelly when he spends a year on the space station while doctors monitor Mark Kelly’s conditions, who will remain on Earth.

Weightlessness has also been an issue. The body does not need to support weight in zero-gravity, resulting in weaker bones. NASA has given astronauts osteoporosis drugs and encouraged them to use a treadmill, which has remedied the problem. Scientists are continuing to evaluate these issues as they prepare for the possibility of sending astronauts to Mars in the future, where health concerns could be catastrophic since astronauts will need to be more self-sufficient.

    This article’s title is one of the most “Thank you, Captain Obvious” titles I think I’ve ever seen.

    What’s next? “Research suggests water is wet” ?

      Scientist prove humans are not designed to breath water?

    In other breaking news, water discovered to be wet.

      but, water isn’t wet to hydrophobic surfaces… wetness is relative, not an absolute. (dives for cover)

  • Jon Gibson

    No shit?!?! WOW!

      Thank you Captain Obvious!

    Funny how things finally come back to the fact that man was made from the dust of the earth! Man was created to have dominion over the earth and all the creatures.
    The Heavens belong to the Lord and the natural man cannot enter this realm and thrive.

      If deep space is your idea of heaven I’d rather go to hell

      • Marietta Alexander

        There are celestial bodies and bodies terrestrial; but the glory of the celestial is one, and the glory of the terrestrial is another. Flesh and blood cannot inherit the kingdom of God; For this corruptible must put on incorruption and this mortal must put on immortality! You must be given a new body to live in God’s realm; repent of your sin and come to Jesus to be born again; then you will inherit eternal life.

    Who would have thought this to be true??? I suppose the next thing these “researchers” will discover is that humans can’t breath water.
