How Space Kills People With Zero Gravity

Find out what it feels like to work in zero gravity. You will be shocked to see how extremely harmful being in space is for the human body.
Even after the astronauts returned to Earth, it took their immune systems a pretty long time to get back to normal function. Astronauts complain that their skin had become dry and itchy. If people remain in a weightless state for longer periods of time, their eyesight doesn't recover on its own, and they require medical attention. Whether you want it or not, your height will increase because the spine will stretch and become more than 2 inches longer. Astronauts reported feeling panicked at night when they woke up and couldn’t feel their arms and legs. They say it feels like your limbs don’t even exist! You’ll most likely end up having thin “bird” legs and a puffy face. Six months in zero gravity means a 6% loss in bone mass. If you remain in zero gravity for some time, the volume of your blood decreases. Astronauts feel like if they bent over, they’d fall flat on their face.
All of these issues are pretty troubling as far as the future of space exploration goes, especially if we’re talking about sending a manned expedition to Mars. That's why nowadays many scientists all over the world are hard at work finding ways to allow humans to not only survive but also thrive in space.

SUMMARY
-Scientists found that the immune systems of those who had been in zero gravity for about half a year actually became weaker.
-Astronauts who spend even a short time in zero gravity notice that their eyesight worsens, and they can't see objects up close.
-Whether you want it or not, your height will increase because the spine will stretch and become more than 2 inches longer.
-When you experience weightlessness for the first time it feels as if you’ve been hanging from a roof and then let go.
-All the liquid in your body moves from the lower to the upper part of your body.
-Your disorientation messes up your sense of balance, which can leave you feeling sick and queasy.
-With each month in space, your bones lose about 1% of their density and important minerals.
-If you remain in zero gravity for some time, the volume of your blood decreases.
-It becomes really hard to even carry your own weight back on Earth.
