Pitkien avaruuslentojen aikana ihmiskehossa tapahtuu merkitt\u00e4vi\u00e4 muutoksia. N\u00e4it\u00e4 ovat muun muassa lihasten ja luuston asteittainen surkastuminen, avaruuspahoinvointi sek\u00e4 syd\u00e4meen ja keuhkoihin liittyv\u00e4t muutokset.<\/p>\n<\/div>\n

T\u00e4llaiset muutokset voivat vaikuttaa astronauttien hyvinvointiin ja suorituskykyyn sek\u00e4 kiertoradalla ett\u00e4 paluun j\u00e4lkeen Maahan.<\/p>\n

Painottomuuden hiljalleen ilmenevi\u00e4 vaikutuksia on tutkittu lukuisissa tutkimuksissa. Yksi helpoimmista ja edullisimmista tavoista tutkia asiaa on s\u00e4nkylepotutkimukset.<\/p>\n

Viimeisten 40 vuoden aikana on toteutettu lukuisia lepotutkimuksia. Ne ovat tarjonneet t\u00e4rke\u00e4\u00e4 tietoa siit\u00e4, miten ihmiset selvi\u00e4v\u00e4t pitkist\u00e4 liikkumattomuusjaksoista.<\/p>\n

Tutkijat hy\u00f6dynt\u00e4v\u00e4t n\u00e4it\u00e4 tutkimuksia uusien l\u00e4\u00e4kkeiden ja muiden keinojen testaamiseen, joilla pyrit\u00e4\u00e4n torjumaan painottomuuden vaikutuksia. Monet n\u00e4ist\u00e4 tutkimuksista kehittyneet laitteet ja hoitomenetelm\u00e4t ovat levinneet klinikoille ja auttaneet potilaita.<\/p>\n
