First cnsider smething as simple as sleep. Its psitin presents its wn challenges. The main questin is whether yu want yur arms inside r utside the sleeping bag.If yu leave yur arms ut，they flat free in zer gravity, ften giving a sleeping astrnaut the lk f a funny ballet(芭蕾)dancer. “I'm an inside guy，”Mike Hpkins says，wh returned frm a six­mnth tur n the Internatinal Space Statin.“I like t be wrapped up.”
On the statin, the rdinary becmes strange.The exercise bike fr the American astrnauts has n handlebars. It als has n seat. With n gravity，it's just as easy t pedal vilently. Yu can watch a mvie while yu pedal by flating a micrcmputer anywhere yu want. But statin residents have t be careful abut staying in ne place t lng.Withut gravity t help circulate air, the carbn dixide yu exhale(呼气)has a tendency t frm an invisible(隐形的) clud arund yur head.Yu can end up with what astrnauts call a carbn­dixide headache.
Lery Chia, 54, an American retired astrnaut after fur flights, describes what happens even befre yu flat ut f yur seat. “Yur inner ear thinks yu're falling.Meanwhile yur eyes are telling yu yu're standing straight. That can be annying—that's why sme peple feel sick.”Within a cuple f days—truly terrible days fr sme astrnauts' brains learn t ignre the panicky signals frm the inner ear, and space sickness disappears.
