Gulu la ofufuza kuchokera ku yunivesite ya Lund linayamba kuphunzira momwe kumwa mowa kumakhudzira thanzi labwino. Asayansi akhala akuyesera kupeza chomwe chiri kusiyana pakati pa zamankhwala a iwo omwe amamwa mowa tsiku lililonse mu dose yaying'ono, ndi omwe sakugwiritsa ntchito konse. Kuwonjezera pa kufufuza kwawo, iwo adagwiritsa ntchito deta kuchokera mu polojekiti ya 2002. Ntchitoyi inali cholinga chofuna kudziwa zambiri zokhudza kuwonongeka kwa mowa kumene Sweden imabala chaka chilichonse.
Zotsatira za ntchito ya asayansi zasonyeza kuti ndalama zamankhwala za anthu osamwa ndizochepa kuposa omwe amadya mowa pang'ono tsiku ndi tsiku. Kotero, izo zimakhala zokayikira kwambiri maganizo omwe alipo kuti mowa mwazing'ono ndi zabwino kwa thanzi.
Pakati pa maphunziro apitalo, mgwirizano unapezedwa pakati pa mowa ndi mlingo wa malipiro. Asayansi atsimikiza kuti malipiro a anthu omwe amamwa mowa nthawi ndi nthawi amaposa omwe samamwa. Ndiye asayansi anafotokoza izi chifukwa chakuti mowa uli ndi phindu la thanzi ndipo anthu omwe amagwiritsa ntchito amathera nthawi yochepera pa mndandanda wa odwala. Komabe, deta yatsopano yomwe imapezeka ndi asayansi kuchokera ku Lund University, imatsutsa mfundoyi. Asayansi akuganiza kuti aganizire kuwerengera kwa matendawa, momwe kumwa mowa, ngakhale pangТono ting'onoting'ono, kungawononge kwambiri thanzi. Njirayi idasintha chithunzichi ndikuwonetsa kuti mowa umasokoneza thanzi. Choncho, kugwirizana kwapakati pa ndalama zapamwamba ndi zakumwa zoledzeretsa ndizokayikitsa kwambiri. Mwina, nthawi zina, kugwirizana pakati pa zizindikiro ziwirizi kulipo, koma zizindikiro zomwe zimakhudza zizindikirozi ndi zazikulu kwambiri kuposa zomwe zikufotokozedwa mu njira yosavuta yochezera mowa.
Asayansi a ku France pambuyo pa kafukufuku wadzaonanso awonetsa chokhumudwitsa: zothandiza zedi za mowa - nthano. Choncho asayansi ochokera ku France anapeza kuti pali kugwirizana pakati pa ziŵeto za khansa ndi kumwa moŵa nthaŵi zonse. Mwachitsanzo, tawonani kuti kapu ya vinyo yoledzera tsiku lililonse imakula 168% pangozi ya khansa ya pakamwa kapena pakhosi. Ndipo zinatsimikiziridwa kuti kugwiritsa ntchito tsiku ndi tsiku mowa pang'ono kumakhala koopsa kwambiri kusiyana ndi kumwa mowa kwambiri nthawi ndi nthawi.
Asayansi a ku America atulukira momwe kumwa mowa nthawi zonse kumakhudzira ubongo. Maphunziro anachitidwa pakati pa anthu oposa zaka 55, onse, pafupifupi 2800 anthu omwe adagwira nawo ntchito. Ophunzira adayesedwa bwino, komanso fodya ndi mowa omwe ankadya. Chifukwa cha ntchito yawo, asayansi apeza kuti ngakhale kumwa mowa pang'ono kumabweretsa ubongo wambiri.
Asayansi a ku Canada asankha kuti chiopsezo chakumwa kwa anthu omwe amadya ngakhale mowa pang'ono kwambiri ndi mowa kwambiri. Chikoka chotere chakumwa mowa nthawi zonse kumabweretsa amuna, komanso kwa amayi, kuyambira msinkhu sichidalira.
Kuti mudziwe molondola kuchuluka kwa mowa wochuluka, ochita kafukufuku anayambitsa chiyero chapadera, chomwe amachitcha kuti chakumwa. Chakumwa 1 chinayesedwa ndi ma ounces 5 (~ 142 g.) Vinyo, 1.5 ounces (~ 42 g.) Wa mowa, ma olasi (~ 340 g) Wa mowa ndi ma ola atatu (~ 85 g). Motero, anthu a ku Canada amapeza kuti omwe amamwa mowa, kawirikawiri samamwa madzi oposa awiri pa nthawi imodzi.
Chimene chimayambitsa kumwa mowa anthu a ku Canada amachititsa chidwi chofuna kusangalala. Choopsa chachikulu cha kusintha kwa tsiku ndi tsiku ndikumwa mowa, kumatanthauza kuti kumwa mowa, munthu amafunika kumwa mowa nthawi zonse. Pang'onopang'ono, kuchuluka kwa mowa kumadzera zakumwa 4-5 pa nthawi, zomwe zimapweteka thanzi. Momwemo, zingakhale zotsimikizirika kuti zimakhala zovulaza kuti munthu azitha kumwa mowa ngakhale panthawi yovuta kwambiri.
Malinga ndi kafukufuku wapadziko lonse, mlingo wa zakumwa zina zimayipitsa thupi la mkazi. Kuchuluka kwa mowa kumakhudza kwambiri thupi, ngakhale litamwetsedwa kamodzi kokha.
Komanso sitingathe koma kunena za zopusitsa zomwe kawirikawiri zimamvekedwa m'maganizo athu. Makolo ambiri amakhulupirira kuti chiwerengero chochepa cha mowa kwambiri sichivulaza, ndipo chingathandize ana, makamaka ngati mwanayo akufuna. Pali lingaliro lakuti ana amadziwa bwino zomwe thupi lawo limafuna ndipo ngati amakopeka ndi mugulu wa mowa, ndiye, m'thupi lawo, palibe zinthu zokwanira zomwe zili mu zakumwa izi. Komanso, ambiri amakhulupirira kuti pakuyesera chakumwa chosavuta, mwanayo safuna kumwa.
Komabe, kafukufuku wopangidwa pakati pa mabanja 6000 anasonyeza kuti mtsogolomu chiwerengero cha uchidakwa pakati pa ana omwe amadya ngakhale mowa pang'ono ndi makolo awo ndipo chilolezo chawo ndi chachikulu kwambiri kuposa awo omwe analetsedwa kumwa mowa ndi makolo. Malingana ndi chiwerengero, ana omwe adamwa mowa pamaso pa makolo ndi osakwanitsa zaka 15 amakhala ovutika ndi uchidakwa.
Motero, chigamulocho n'chokhumudwitsa. Kodi nthawi zambiri mumamwa mowa mwauchidakwa? Ponena za mowa, asayansi padziko lonse lapansi akuwonetsa chisamaliro chodabwitsa: mowa ndi wowopsa ngakhale pang'onozing'ono.
