They need to exercise with regularity because the muscles begin to atrophy and bones begin to lose density . This present shuttle mission to the International Space Station brought the C.O.L.B.E.R.T. ( named after the comedian) which is an acronym for Combined Operational Load Bearing External Resistance Treadmill ; see related links .
If the space station is pressurized, I don't think astronauts need to where space suits.
No, astronauts actually don't do laundry in space. They have to throw away there clothes after they get dirty, because their is no way to wash them.
The reason it is so cold in space and astronauts need warm clothing is because thair is NO element in space for warm energy conduction, an element is any natral mass.
No, because most astronauts just make it into space but don't walk on the moon and their still considered astronauts.
omg they go in a sleeping bag and they freakin tape their selves to the wall in a space ship do you peeps understand. for exercising they use only one tool the ergeometer witch they need to do for two hours.
their suits are very heavy.
There's no gravity in space - this affects their muscles. Exercising keep the muscles toned.
Astronauts have work out machines to keep their muscles strong. They exercise every day.
no because they don't need that much energy <33
In a zero gee environment (weightlessness), the Human Body almost immediately begins losing muscle and bone mass. If they did not exercise, Astronauts returning from Space after a long stay on the Space Station would be unable to walk, and would have to be in a wheelchair for weeks before they could learn to walk again.
They need to take it with them. There is no oxygen in space

Astronauts require less sleep than normal; Theoretically because the astronauts always have to be alert in a dangerous setting like space.

I am not sure, ask NASA
