Under l\u00e5nga rymduppdrag sker stora f\u00f6r\u00e4ndringar i m\u00e4nniskokroppen. Dessa omfattar gradvis f\u00f6rlust av muskelmassa och benmassa, rymdsjuka samt f\u00f6r\u00e4ndringar som r\u00f6r hj\u00e4rtat och lungorna.<\/p>\n<\/div>\n

S\u00e5dana f\u00f6r\u00e4ndringar kan p\u00e5verka astronauternas v\u00e4lbefinnande och prestationsf\u00f6rm\u00e5ga, b\u00e5de i omloppsbana och efter \u00e5terkomsten till jorden.<\/p>\n

M\u00e5nga studier har genomf\u00f6rts f\u00f6r att f\u00e5 mer kunskap om de gradvisa effekterna av tyngdl\u00f6shet. Ett av de enklaste och billigaste s\u00e4tten att g\u00f6ra detta p\u00e5 \u00e4r studier med s\u00e4ngl\u00e4ge.<\/p>\n

Under de senaste 40 \u00e5ren har ett stort antal studier om s\u00e4ngl\u00e4ge genomf\u00f6rts. Dessa har gett viktig information om hur m\u00e4nniskor hanterar l\u00e5nga perioder av inaktivitet.<\/p>\n

Frivilliga ligger i s\u00e4ngen i flera veckor, ofta med huvudet lutat ned\u00e5t. Eftersom de knappt anv\u00e4nder sina ben och muskler beter sig deras kroppar p\u00e5 ungef\u00e4r samma s\u00e4tt som de skulle g\u00f6ra i rymden.<\/p>\n

Forskare anv\u00e4nder dessa studier f\u00f6r att testa nya l\u00e4kemedel och andra metoder f\u00f6r att motverka effekterna av tyngdl\u00f6shet. M\u00e5nga instrument och behandlingar som utvecklats i samband med detta har tagits i bruk p\u00e5 kliniker och hj\u00e4lpt patienter.<\/p>\n

Framtida forskning p\u00e5 den internationella rymdstationen lovar \u00e4nnu fler h\u00e4lsof\u00f6rdelar. P\u00e5 sikt kommer denna forskning ocks\u00e5 att bana v\u00e4g f\u00f6r m\u00e4nniskor att resa bortom jordens omloppsbana och utforska andra v\u00e4rldar.<\/p>","protected":false},"excerpt":{"rendered":"
