Sleep and Relaxation
BY BEN, DYLAN AND SIDNEY!
Do astronauts require more or less sleep than normal when they are in space?
Studies show astronauts sleep 0.5 to 2.5 less in space than on Earth, despite NASA’s recommendation of 8 hours
Believed to be result of the body feeling less fatigued as a result of being in microgravity
Although astronauts report to feel fully rested after 6 hours, sleeplessness can cause irritability, forgetfulness and fatigue, an irritation to them while working
How many hours of sleep do astronauts
usually get each night? Each astronaut is different
Some astronauts take sleeping pills
Sleep is affected by day night cycles, work loads and noises
They get between two and eight hours of sleep per 24 hours.
How do astronauts relax in space?
Communicate with family via email, internet phone and Hand radio
Put together an electronic collection of family photos, messages, video clips and reading materials to watch/read
During their mission, crew receive packages with CD’s, books, magazines, photos and letters
In addition, ISS has two generic library lockers that contain music, books and videos
Many say the most relaxing thing is looking out the window and staring at the Earth and surrounding universe
Do astronauts sleep in a bed? If they do not ,how do they sleep?
They sleep in many different way
They can sleep in a sleeping bag or in their only little closet room or bunk beds
During the day they can fold the bunk beds up out of the way
In space they can sleep horizontally or vertically it wont matter as they are connected to bars because there's no gravity
By the time the STS-9 took off they had bunk beds equipped with an individual light, communication station, a fan, sound suppression blanket and sheets with micro gravity restrains
Interesting facts Use Greenwich Mean Time (GMT) for
schedule Often shuttle and ISS crew sleep and wake
at different times Extremely demanding schedule Whole day is strictly planned Internet is available for web browsing
