\t\tJe v\u0161ak mo\u017en\u00e9 \u010dosi podobn\u00e9, \u010do za\u017eila Kochov\u00e1, navodi\u0165 \u010dloveku v\u00a0pozemsk\u00fdch podmienkach?<\/p>\n

Odpove\u010f je jednoduch\u00e1: \u00c1no, ale asi by ste sa unudili k\u00a0smrti.<\/p>\n

1.\u00a0Such\u00e1 imerzia Vedci v\u00a0Rusku a v\u00a0ESA (Eur\u00f3pska vesm\u00edrna agent\u00fara) pou\u017e\u00edvaj\u00fa Dry Immersion.<\/p>\n

\t\t\tAko to funguje: Dobrovo\u013en\u00edk si \u013eahne do vane s\u00a0vodou, ktor\u00e1 je pokryt\u00e1 \u0161peci\u00e1lnou nepremokavou tkaninou (ako ve\u013emi vo\u013en\u00fd igelit). \u010clovek je teda \u201eponoren\u00fd\u201c, ale ost\u00e1va\u00a0such\u00fd.
\n\t\t\t\u010co sa deje: Voda rovnomerne tla\u010d\u00ed na cel\u00e9 telo, \u010d\u00edm simuluje stav beztia\u017ee. Mozog prestane dost\u00e1va\u0165 sign\u00e1ly o\u00a0tlaku na chodidl\u00e1 alebo chrb\u00e1t.
\n\t\t\tV\u00fdsledok: U\u017e po 3\u00a0d\u0148och v\u00a0takejto vani maj\u00fa \u013eudia probl\u00e9m udr\u017ea\u0165 rovnov\u00e1hu. Po 10\u00a0d\u0148och by si na tom bol podobne ako Christina Kochov\u00e1\u00a0\u2013 tvoj nervov\u00fd syst\u00e9m by bol \u201erozladen\u00fd\u201c a pri pokuse postavi\u0165 sa by si mal pocit, \u017ee podlaha pod tebou\u00a0pl\u00e1va.<\/p>\n

2.\u00a0Bed Rest Studies (inak povedan\u00e9 extr\u00e9mny Netflix marat\u00f3n) NASA pravidelne plat\u00ed dobrovo\u013en\u00edkom tis\u00edce eur za to, aby str\u00e1vili napr\u00edklad 60\u00a0dn\u00ed v\u00a0posteli.<\/p>\n

\t\t\tM\u00e1 to v\u0161ak h\u00e1\u010dik: poste\u013e je naklonen\u00e1 o\u00a0m\u00ednus \u0161es\u0165 stup\u0148ov (hlava je tak ni\u017e\u0161ie ako nohy).Pre\u010do ten sklon? Aby sa simuloval presun telesn\u00fdch tekut\u00edn do hornej \u010dasti tela, presne tak, ako sa to deje v\u00a0kozme (preto maj\u00fa astronauti vo vesm\u00edre \u201eopuchnut\u00e9\u201c tv\u00e1re a tenk\u00e9\u00a0nohy).
\n\t\t\t\u010co sa stane: Svaly na noh\u00e1ch a chrbte, ktor\u00e9 n\u00e1s dr\u017eia vzpriamene (tzv. antigravita\u010dn\u00e9 svaly), za\u010dn\u00fa v\u00a0priebehu dn\u00ed ochabova\u0165.
\n\t\t\tN\u00e1vrat do reality: Ke\u010f sa t\u00edto \u013eudia po mesiaci \u010di dvoch prv\u00fdkr\u00e1t postavia, \u010dasto omdlievaj\u00fa (krv im ste\u010die do n\u00f4h a mozog ostane na suchu) a ich ch\u00f4dza pripom\u00edna niekoho po ve\u013emi divokom ve\u010dierku.<\/p>\n

3.\u00a0Dlhodob\u00e1 sadra alebo choroba. Mo\u017eno si to za\u017eil ty alebo niekto v\u00a0tvojom\u00a0okol\u00ed.<\/p>\n

\t\t\tAk m\u00e1\u0161 nohu v\u00a0sadre 6\u00a0t\u00fd\u017ed\u0148ov a nepou\u017e\u00edva\u0161 ju, po jej odstr\u00e1nen\u00ed sa deje toto:Svalov\u00e1 atrofia: Sval je vidite\u013ene\u00a0ten\u0161\u00ed.
\n\t\t\tSenzomotorick\u00fd v\u00fdpadok: Tvoj mozog na chv\u00ed\u013eu \u201ezabudol\u201c, ako t\u00fa nohu presne ovl\u00e1da\u0165. C\u00edti\u0161 sa, akoby si mal namiesto nohy dreven\u00fd\u00a0k\u00f4l.
\n\t\t\tPre\u010do je to u\u00a0astronautov in\u00e9? Hlavn\u00fd rozdiel je v\u00a0tom vn\u00fatornom uchu (vestibul\u00e1rnom apar\u00e1te). Na Zemi, aj ke\u010f le\u017e\u00ed\u0161 10\u00a0dn\u00ed v\u00a0posteli, gravit\u00e1cia st\u00e1le \u0165ah\u00e1 tvoje \u201eu\u0161n\u00e9 kamienky\u201c (otolity) smerom dole.
