Pfupisa nyaya yacho:  Kana mumwe wako achiridza mhere zvikuru pamubhedha, ungava nomuedzo wokumurova mumbabvu ndokudzokera kunorara. Asi masayendisiti akanyevera kuti chiratidzo chokutanga chokusaziva chinogona kuva chokutsamwa ikoko kunotsamwisa usiku. Vanzveri vakawana kuti vanhu vane zvinetso zvokufema pavanenge vakarara vane bviro huru yokuva nokuderera kwokutanga kweyeuko nemimwe mibato yehuropi. Mune kumwe kuongorora kunonetsa, vakawana kuti vanhu vane chirwere chokurara vachirutsa mweya (sleep apnea) - chirwere chinowanzoratidzwa nokuridza mhere zvakanyanya - vakatanga kuderera pfungwa makore anopfuura gumi zvisati zvaitika, paavhareji, kupfuura vaya vasina dambudziko rokurara. Vanhu vane zvinetso zvokufema pavanenge vakarara vane mikana yakawanda yokutanga kuderera mundangariro nemimwe mibato yehuropi. Zvakawanikwa nevatsvakurudzi vokuUnited States zvakaratidzawo kuti chirwere cheAlzheimer chinogona kukurumidza kutanga kuvanhu vane matambudziko okurara. Vanenge hafu yemiriyoni yevanhu vokuBritain vane chirwere chokurara vasingafemi, icho chinowanzowanika muvarume vane uremu hwakanyanyisa vane makore ari pakati nepakati. Mamiriro acho ezvinhu anoita kuti tsandanyama dziri mumigwagwa yokufema dzibatane mukati mokurara, izvo zvinodimbura kuwanwa kwemhepo, kazhinji kazhinji zvichiguma nokuhwinya kukuru. Kunokonzera kukanganiswa kwokurara uye kuneta masikati, kuchisimudzira BP. Munyori wetsvakurudzo Dr. Ricardo Osorio, weNew York University, akati: <unk>Mafungiro asiri omuzvarirwo okufema panguva yokurara akadai sokuridza zvikuru uye kupumha kwemhepo muhope zvakajairika muvakweguru.<unk> Chikwata chokutsvakurudza chakadzidza nhau dzokurwara dzavanhu 2470, vane makore 55 kusvika ku90. Ongororo yavo, yakabudiswa mumagazini inonzi Neurology, yakawana kuti vanhu vane zvinetso zvokufema pavanenge vakarara vakaonekwa kuti vane chirwere chisina kunyanya kuipa chokufunga pazera remakore 77 avhareji. Vaya vakanga vasina zvinetso zvokufema, mukuenzanisa, kazhinji kazhinji havana kuona kuderera kusvikira pazera ramakore 90 - makore anopfuura gumi gare gare. Muboka iroro, vaya vaiva nezvinetso zvokufema panguva yokurara vakavawo nechirwere cheAlzheimer makore mashanu vasati varwara kupfuura vaya vakanga vasina zvinetso zvokufema panguva yokurara, paavhareji yezera remakore 83 zvichienzaniswa ne88.
