  2. 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

  3. 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.
