Uninzi lwethu lulala ngokwaneleyo, iSayensi ithi
Umxholo
Usenokuba uvile: Kukho ingxaki yokulala kweli lizwe. Phakathi kweentsuku ezinde zomsebenzi, iintsuku ezimbalwa zeeholide, nobusuku obukhangeleka njengeentsuku (enkosi kubuninzi bethu bezibane ezenziweyo), asibambi nje umgangatho owaneleyo we-z. Isihloko esinye samva nje sithi "Ingxaki yokulala yaseMelika isenza sigule, sityebe kwaye sisidenge." Ingxaki kuphela kweli bali elibi? Akuyonyani, ubuncinci kuhlalutyo olutsha ku UkuPhononongwa kweyeza efumanise uninzi lwethu silele ngokwaneleyo isixa esisempilweni.
Abaphandi kwiYunivesithi yaseArizona State bavavanya idatha kwizifundo ezibuyela umva kwiminyaka engama-50 kwaye bafumanisa ukuba kwisiqingatha senkulungwane esidlulileyo, umntu omdala oqhelekileyo uhlala efumana-kwaye usaqhubeka-ejikeleze iiyure ezisixhenxe kunye nemizuzu engama-20 yokuvalwa kwamehlo ubusuku ngabunye. Yiyo loo nto kuluhlu lweeyure ezisixhenxe ukuya kwezisibhozo iingcali ezithi kufuneka sibe kulo. (Ukuba awunguye omnye waba bantu baphakathi, zama ezinye zezi Mveliso eziZifikelelekayo zokuLala ngoBusuku obungcono.)
Ke kutheni le nto yonke i-hype malunga namaMerika angalaliyo akhubeka ebomini njenge zombies ngekomityi yekofu esandleni esinye kunye nebhotile ye-Ambien kwelinye? Ewe, ukuqala, uphando lwamva nje oludibanisa i-shuteye encinci kunye nomngcipheko ophezulu woxinzelelo, ukutyeba kakhulu, isifo seswekile, isifo sentliziyo, kunye nomhlaza sisemthethweni. Yimbono nje yokuba uninzi lwethu alulali ngokwaneleyo oko kuyintsomi, utsho umbhali okhokelayo uShawn Youngstedt, Ph.D.
"Enye yeengongoma eziphambili esizamile ukugxininisa kweli phepha kukuba iziphumo zethu ziyahambelana nokuphononongwa okuninzi kwedatha exeliweyo ekwabonisa ukuba ixesha lokulala alitshintshanga kwesiqingatha senkulungwane esidlulileyo, kwaye nepesenti yabantu ndilale ngaphantsi kweeyure ezintandathu ngobusuku, utshilo. "Asizizo zonke izifundo ezibonise oku, kodwa uninzi luye lwabona."
Ewe, uvoto ukusukela ngo-1975 luhlala lubonisa phantse i-60 pesenti yabantu baseMelika ingxelo yokufumana ngaphezulu kweeyure ezintandathu zokuvala amehlo ngobusuku. (Ngaba Kungcono Ukulala okanye Ukusebenza?)
U-Youngstedt uthi le ngcamango iphosakeleyo ivela ekudidekeni malunga nokuba yintoni eyona nto ilalayo. “Kanye njengokuba umntu enokufumana amanzi amaninzi, ukukhanya kwelanga, iivithamini, okanye ukutya, kukho izifundo ezininzi ezibonisa ukuba umntu unokulala kakhulu,” uyachaza. "Iiyure ezisibhozo zokulala ebusuku ngokwesiko bekucingelwa ukuba lelona lixabiso elifanelekileyo kwezempilo. Nangona kunjalo, iiyure ezisibhozo okanye nangaphezulu kuye kwaboniswa ukuba kunxulunyaniswa nokufa kunye nezinye iingozi zempilo. Ke, ngokwembono yempilo yoluntu, ukulala ixesha elide kunokuba yinto inkxalabo enkulu. " (Kwaye zikho ezi ndlela zilishumi elinanye onokuthi uzigulise kusasa.)
Okubi nangakumbi kukuba, wongeza ukuba lonke eli xesha lokulala brouhaha eneneni lenza ukuba abantu bafumane amanqaku okulala okungaphantsi ngokubanika enye into yokuphosa kunye nokujika iindaba ezimbi malunga nokucinga ukuba amaxhala anokubangela uxinzelelo kunye nokulala. Kwaye nezo pilisi zokulala azikwenzeli nto. "Kuphephe iipilisi zokulala; ukusebenzisa ipilisi yokulala ebusuku kuyingozi njengokutshaya ubuncinane ipakethe yecuba ngosuku," utsho.
Endaweni yoko, ucinga ukuba sonke kufuneka siphole (ewe, yiPh.D esemthethweni leyo sithethe) malunga nokulala kwethu kwaye sinikele ingqalelo ngakumbi koko imizimba yethu isixelela kona.
Elona nani lifanelekileyo? Eyona mingcipheko imbalwa yezempilo iye yanxulunyaniswa neeyure ezisixhenxe zokusnuza, utshilo u-Youngstedt. Kodwa ukuba uziva ulungile ulele kancinci okanye kancinci kancinci ke musa ukubila. Isitshixo kukufumana kuphela ukuvala iliso njengoko ufuna ukuziva wonwabile, uphaphile kwaye uphumle ngokwaneleyo. Uthi: "Ukuzama [ukuzinyanzela] ukuba ulale ngakumbi kunoxanduva lokubangela ukuba ulale kakubi kwaye kunokuba yingozi empilweni, utshilo. (Ngaphandle? La maxesha mane ufuna ukulala ngakumbi.)
Nye Ngaphantsi Yintoni ekufuneka ukhathazeke ngayo xa isiza empilweni yethu? Siyasithanda isandi soko!
