Alala kangakanani amakati: konke mayelana nemodi yezilwane ezifuywayo

Ingabe amakati ayizilwane zasebusuku ngempela? Abaningi babo bazulazula emakamelweni amnyama endlu yokulala phakathi kwehora lesithathu nelesine ekuseni futhi bangadinga okungenani ukudla okulula okukodwa kwakamuva.

Naphezu kokungahloniphi okusobala kwamakati endleleni yokulala yomuntu, empeleni akuzona izilwane zasebusuku, kodwa izilwane zakusihlwa. Lesi sigaba sezinto eziphilayo sihlanganisa izilwane ezisebenza kakhulu ekuseni nakusihlwa, kuchaza i-Mother Nature Network. Izilwane eziningi ezinogwaja, kusukela konogwaja kuya emabhubesini, zavela ukuze ziphile lapho amazinga okushisa ephansi kakhulu endaweni yazo yasogwadule.

Ukwazi iphethini evamile yokuziphatha kwakusihlwa - ukuqhuma kwamandla amafushane okulandelwa isikhathi eside sokuphumula - kuzosiza ukuqonda ukuthi kungani inani eliphakeme lomsebenzi wokudlala wekati livame ukwenzeka ngesikhathi lapho umuntu elele.

izilwane zasebusuku

Ngempela izilwane zasebusuku, njengama-raccoon nezikhova, zihlala ziqaphile ubusuku bonke futhi, zisizakala ngobumnyama, zizingela inyamazane yazo. Izilwane ezihlala nsuku zonke njengezingwejeje, izimvemvane nabantu basebenza amashifu osuku. Kodwa izilwane eziphila emanzini zisizakala ngokufiphala kokukhanya kwemini nobumnyama obufiphalayo ukuze zenze okungcono kakhulu emhlabeni wemini nobusuku.

I-BBC Earth News iyachaza: “Inkolelo-mbono ecashunwe kakhulu yokusebenza kwe-crepuscular iwukuthi inikeza ukulinganisela okuhle. “Kulesi sikhathi, kukhanya ngokwanele ukuthi ungabonakala, futhi kumnyama ngokwanele, okunciphisa amathuba okuba ubanjwe futhi udliwe. Izilwane ezidla ezinye ezinjengoklebe, aziboni kahle ngesikhathi sokuhwalala, okwenza kube nzima ngazo ukubamba izilwane ezincane nezihlwabusayo.

Nakuba lokhu kuziphatha kuwumzwelo wemvelo yazo zonke izinhlobo zezilwane, indlela yokuphila yesilwane yasebusuku, emini, noma ye-crepuscular inqunywa kakhulu ukwakheka kwamehlo aso. Kwezinye izidalwa ezimnyama, njengamakati, i-retina inesimo esifana nesesikwele, esifana nesezilwane zasebusuku. Lokhu kuchaza ukuthi kungani ngisho ekamelweni elimnyama kakhulu, kulula kuye ukuthi abambe uzwane lomnikazi wakhe ukuze adlale.

"I-palpebral fissure eqondile ivame ukutholakala ezilwaneni ezizingelayo," uMartin Banks, usosayensi wamehlo, etshela iNational Public Radio (NPR). I-slit eqondile "inezici ezibonakalayo eziyenza ifaneleke" kumakati alindayo ngaphambi kokuba ahlasele inyamazane yawo. Ekatini, lokhu kuziphatha kungase kubonakale kusihlwa noma ekuseni.

Ukulala noma ukungalali

Nakuba amakati ehlelwe ngokwebhayoloji ukuthi asebenze kakhulu lapho kuhwalala, amanye awo ancamela ukugijima entathakusa. Phela, akunakwenzeka ukuthi ikati lizojabula kakhulu uma lilala amahora ayishumi nesithupha ngokulandelana. Izilwane ezifuywayo eziningi zivusa abanikazi bazo okungenani kanye ngobusuku. Abanikazi abayithandi. Yilolu hlobo lwemigilingwane yasebusuku oluvame ukuphakamisa umbuzo othi, “Ingabe ngempela amakati ayizilwane zasebusuku?”

Indlela yokulala yekati idlala indima ebalulekile. Ukulala nokuphumula akufani ezilwaneni njengoba kunjalo kubanikazi bazo, kuchaza i-Animal Planet. Amakati “ane-REM ne-non-REM, kodwa kulezi zigaba ikati livaleka ngokuphelele.” Amakati ahlale eqaphile, ngisho nalapho elele.

Uma bevuswa umsindo ongavamile, bavuka cishe ngaso leso sikhathi futhi balungele ngokuphelele ukwenza okuthile. Yileli khono elivumela amakati nezilwane zasendle ngokujwayelekile ukuthi zihlale ziphephile futhi zizidlela ukudla kwazo ngokwemvelo. Abanikazi abaningi baye baqaphela izimo lapho abangane babo abanoboya, belele ngokujulile ngakolunye uhlangothi lwegumbi, beseduze komunye nomunye ngomzuzwana kamuva, kwakudingeka kuphela ukuvula ikani lokudla ngokuchofoza.

Amakati afuywayo akusadingeki ukuba azingele ukuze azitholele ukudla, kodwa lokhu akusho ukuthi lezi zimo zemvelo sezinyamalele. Njengoba uprofesa wezakhi zofuzo uDkt. Wes Warren atshela i-Smithsonian Magazine, “amakati awagcinile amakhono awo okuzingela, ngakho awancikile kangako kubantu ukuze athole ukudla.” Kungakho ikati nakanjani “lizozingela” amathoyizi alo, ukudla nokudla kwekati.

Imvelo yokuzingela yekati ixhumene ngokungenakuhlukaniswa nemvelo yayo yokuhlwa, okuholela ezinhlotsheni ezimangalisayo zokuziphatha ekhaya. Kufana nokuziphatha kokhokho bakhe basendle - njengebhubesi elincane elihlala efulethini.

Ukulala okubuyisela

Umqondo "wokulala kwekati" - ukulala okufushane kokululama - uvele ngesizathu. Ikati lilala kakhulu. Umuntu omdala udinga ukulala amahora ayishumi nantathu kuya kwayishumi nesithupha ubusuku ngabunye, kanti amakati namakati amancane afika emahoreni angamashumi amabili. 

Amakati “athulula” ukudla kwawo emjikelezweni oqhubekayo wamahora angu-24 wezikhathi ezimfushane zokulala esikhundleni sokulala okukodwa okude. Bawasebenzisa ngokugcwele lawa maphupho, bagcine amandla azowasebenzisa ngezikhathi zomsebenzi ophakeme. Yingakho ikati lilala ngendlela ehlukile kunathi - isimiso salo sakhiwe ngendlela ehluke ngokuphelele.

Nakuba izikhathi zokusebenza kwekati zingase zibe zifushane, zishubile. Njengazo zonke izilwane zakusihlwa, umngane onoboya okhiqizayo unekhono elihle ekuqongeleleni nasekusebenziseni amandla akhe. Ukuze lenze ngokugcwele lezi zikhathi zomsebenzi, ikati kufanele likhulule wonke amandla futhi lizofuna ukuzijabulisa ngokungakhathali. Mhlawumbe uzoshayela amabhola akhe ahlabayo azungeze indlu noma aphose ithoyizi nge-catnip emoyeni. Ngesikhathi esifanayo, angakwazi ukwenza imigilingwane ehlukahlukene endlini, ngakho-ke udinga ukumqapha ngokucophelela ukuvimbela ukunwaya kwe-hooligan kanye nelukuluku eliyingozi.

Izikhathi ezinjalo ezisebenzayo zizonikeza abanikazi ithuba lokufunda ukuziphatha kwekati futhi bakubone kusebenza. Ingabe uyayibuka ngesineke ithoyizi elithambile isigamu sehora ngaphambi kokuba agxume? Ingabe ulunguza ekhoneni, ecupha izinto ezenza sengathi zingandiza? Ukugoqa umata kuba yi-mink engavamile yamabhola acwebezelayo? Kuyajabulisa kakhulu ukubuka ukuthi ikati elifuywayo lilingisa kanjani ukuziphatha kwezihlobo zalo zasendle.

Amanye amakati angaba namandla, kungakhathaliseki ukuthi imizwa yemvelo noma inzalo iwanquma kanjani. Kodwa wonke amakati ahle kakhulu ekugcineni amandla futhi asetshenziswe ngokuphumelelayo ngangokunokwenzeka phakathi nezikhathi zokusebenza. Kungamahora okuhwalala aveza ubuntu babo obukhanyayo.
