Experimenters from the University of Texas have designed a new vacuum- equipped resting bag that can pull down body fluids that naturally flowed into our heads while sleeping in a supine position. When in space, astronauts can suffer from problems in vision as these fluids push and reshape the reverse of the eyeball.
The new study published last week in JAMA Ophthalmology plant that three days of lying flat in a simulated microgravity terrain convinced enough pressure to slightly alter the shape of the eyeball but no similar change was seen when the new suction technology was used We do n’t know how bad the goods might be on a longer flight, like a two- time Mars operation,” said one of the authors Benjamin Levine in a release. He’s a cardiologist who’s helping NASA address the health pitfalls of brain pressure and abnormal blood inflow in space.
“ It would be a disaster if astronauts had similar severe impairments that they could n’t see what they ’re doing and it compromised the charge Last Time NASA said that astronaut Michael Barratt who flew a six-month charge aboard the International Space Station suffered from Space-Associated Neuro-Ocular Pattern (SANS). The symptoms include swelling in the optical slice, which is where the optical whim-whams enters the retina, and leveling of the eye shape.
Steve Laurie, a scientist with NASA’s Human Health and Performance Directorate said that signs of SANS appear in roughly 70 per cent of crew members The resting bag has a solid frame, shaped like a space capsule, and fits over a person from the midriff down. The study included ten levies including one of the authors Dr James Leidner. He’s an internal drug hospitalist in San Antonio.
The levies spent three days sleeping eight hours in a exploration room and three days in sleeping bags for eight hours. The platoon also compared the changes in the brain after each stint The experimenters add that several questions need to be answered before NASA brings this technology to the space station, including the optimal quantum of time astronauts should spend in the resting bag each day.
