Ubusuku ngabunye obuchithwe ulele ekamelweni elikhanyayo, esikhundleni segumbi elinokukhanya kalufifi, kungaholela ekushayeni kwenhliziyo okuphezulu ngobusuku obubodwa kanye nokumelana ne-insulin ngakusasa ekuseni, ucwaningo oluncane luphakamisa.
Ucwaningo lwaluhlanganisa amaqembu amabili abantu abadala abangu-10 abanempilo enhle. Elinye iqembu lalilala emakamelweni akhanya kalufifi ubusuku obubili obulandelanayo kanti elinye lalilala emakamelweni akhanya kalufifi ngobunye ubusuku bese lilala emakamelweni akhanya ngokusesilinganisweni ngobunye, ngokocwaningo. Amakamelo akhanya ngokusesilinganisweni ayekhanyiswe ngokukhanya okukhazimulayo okungu-100 ngaphezulu, okukhanya ngendlela ebekungaba ngayo ngosuku oluguqubele.
Ukukhanya okungu-100 lux nakho kungaqhathaniswa nesikrini se i-tv ivuliwe ekamelweni elimnyama noma ngesibani somgwaqo esikhanya efasiteleni ngeveli elincanyana.
Ukwanda kwenhliziyo
Bonke abahlanganyeli bocwaningo babegqoke iziqapha zenhliziyo ukuze balale, futhi ngobusuku besibili, iqembu elalilala emakamelweni akhanya ngokusesilinganisweni labonisa ukwanda okuphawulekayo kwezinga lokushaya kwenhliziyo ngesikhathi belele, uma kuqhathaniswa nobusuku bangaphambili, abacwaningi baphawula. Iqembu elilale ekukhanyeni okufiphele ubusuku bonke alibonisanga izinguquko ezibalulekile.
Ucwaningo lubonisa ukuthi ukushaya kwenhliziyo kuyenyuka uma silala egumbini elikhanyiswe ngokusesilinganisweni. Yize silele i-autonomic nervous system iyasebenza. Isistimu yezinzwa ezizimele ilawula izinqubo zomzimba ezizenzekelayo, ezinjengokuphefumula, ukushaya kwenhliziyo, ukuvuleka komfundi, nokugaya ukudla, kanye nokusabela ukulwa noma ukundiza. Uma i-autonomic nervous system inyusa izinga lokushaya kwenhliziyo ebusuku, kubi. Ngokuvamile, izinga lokushaya kwenhliziyo kanye namanye amapharamitha enhliziyo liphansi kakhulu ebusuku futhi liphakeme kakhulu phakathi nosuku.
Ukwanda kokumelana ne-insulin
Ababhali bocwaningo baphinde benza izivivinyo ezahlukahlukene ukulinganisa ukumelana ne-insulin kwabahlanganyeli njalo ekuseni ocwaningweni, ngemva kokuvuka kwabo. I-hormone insulin ngokuvamile isiza amangqamuzana amunce i-glucose, noma ushukela, egazini. Kodwa lapho amangqamuzana amelana ne-insulin, awayithathi kalula i-glucose, futhi umzimba ukhiqiza i-insulin eyengeziwe ukuze unxephezele. Ngokuhamba kwesikhathi, amangqamuzana aba ukumelana nalawa mazinga aphezulu kakhulu e-insulin, okubangela amazinga kashukela egazini ayakhuphuka.
Ngosuku lokuqala ekuseni, ngemva kokulala emakamelweni akhanya kalufifi, womabili amaqembu ocwaningo aba nemiphumela efanayo ekuhlolweni kokumelana ne-insulin. Lezi zivivinyo zazihlanganisa ukuhlolwa kwemodeli ye-homeostatic yokumelana ne-insulin, ukubala okucabangela izinga likashukela egazini kanye namazinga e-insulin, kanye nokuhlolwa okuqondile kokuthi umzimba usabela kanjani ku-glucose, okubizwa ngokuthi ukuhlolwa kokubekezelela ngomlomo ku-glucose kanye ne-Matsuda Insulin. Inkomba yokuzwela.
Ngosuku lwesibili ekuseni, labo okwakudingeka balale ngokukhanya benze okubi kakhulu kulezi zivivinyo, kuyilapho iqembu elalilele ngokukhanya okufiphele lenze cishe okufanayo noma kangcono kunangangaphambili. Ukuchayeka ngobusuku obubodwa bokukhanya kwe-ambient ngesikhathi sokulala kwenyusa izinyathelo zokungazweli kwe-insulin ngakusasa ekuseni.
Ngakho-ke kubonakala sengathi iqiniso elingenabungozi lokulala ngokukhanya lingaba yingozi empilweni.
