Fifty percent of Space Shuttle astronauts took sleeping pills and still got 2 hours less sleep each night in space than they did on the ground. NASA is researching two areas which may provide the keys to a better night's sleep, as improved sleep decreases fatigue and increases daytime productivity.
Sleeping in space requires that astronauts sleep in a crew cabin, a small room about the size of a shower stall. They lie in a sleeping bag which is strapped to the wall. [5] Astronauts have reported having nightmares and dreams, and snoring while sleeping in space. [6] Sleeping and crew accommodations need to be well-ventilated. [7]
During a camp-out, astronauts sleep overnight in the airlock prior to an EVA, lowering the air pressure to 10.2 psi (70 kPa), compared to the normal station pressure of 14.7 psi (101 kPa). [34] Spending a night at the lower air pressure helps flush nitrogen from the body, thereby preventing " the bends ".
If a tether breaks, the backpack will propel them back to the ISS. If that fails, saving an astronaut floating off into space might require several tethers hooked together, a SAFER, and, to be ...
Results indicate that, on average, performance with a blood alcohol level of 0.05% remained equivalent to performance after being awake for 16.9 to 18.6 hours. Performance with a blood alcohol level of 0.1% was equivalent to performance after being awake for 17.7 to 19.7 hours, or to restricted sleep of 4 to 5 hours per night for 1 week. [23]
A 2004 study found people who slept on their left side had more nightmares. The research found about 41 percent of left-side sleepers had nightmares, compared to 14.6 percent of right-side sleepers.
Christmas is less than a week away, and even the night sky is spreading some holiday cheer with what could be the largest Christmas tree in the universe. On Tuesday, NASA released an image of NGC ...
The Digital Astronaut was described as "an integrated, modular modeling and database system that will support space biomedical research and operations, enabling the identification and meaningful interpretation of the medical and physiological research required for human space exploration, and determining the effectiveness of specific individual ...
