JAKARTA, iNews.id – Will Astronaut requires perfect vision. Unfortunately, space effects can cause astronauts to return to Earth with limited visibility.
Now researchers at UT Southwestern Medical Center have developed a sleeping bag that could prevent or reduce the problem. The sleeping bag effectively sucks fluid out of the astronaut’s head.
More than the half NASA-Astronaut who flew to the International Space Station (ISS) for more than six months had visual problems of varying degrees. In one case, astronaut John Philips returned from a six-month stay on the ISS in 2005 with vision reduced from 20/20 to 20/100, the BBC reports.
For example, when traveling to Mars for several years, this could be a problem. According to lead researcher Dr. Benjamin Levine this would be a disaster if the astronauts were disturbed so much that they could not see what they were doing and disrupted the mission.
Fluid builds up in your head while you sleep. However, gravity pulls it back into your body when you wake up. However, more than half a gallon of fluid will collect in the head in a low-gravity room.
This, in turn, puts pressure on the eyeball, causing a flattening that can lead to impaired vision, a disorder known as spaceflight neuro-ocular syndrome, or SANS.
