Summary

A day on the International Space Station involves a 24-hour cycle of work and rest, with 8 hours of sleep in a sleeping bag attached to a hook on the wall to prevent floating away. Astronauts sleep in front of a fan to avoid breathing in exhaled carbon dioxide. Washing and brushing teeth are challenging due to lack of gravity, with solutions including using wash cloths and suction or swallowing toothpaste. Water is recycled using a spinning distiller, and is also used to produce oxygen through electrolysis. The internal atmosphere is maintained at one atmosphere, with a mix of 78% nitrogen and 21% oxygen. Astronauts exercise for 2 hours a day to prevent muscle and bone loss, and may perform EVAs (extra-vehicular activities) in space suits with lower pressure and 100% oxygen. Decompression is necessary before EVAs to prevent the bends, and astronauts may "camp out" in the airlock overnight to breathe off nitrogen.
