Umxholo
Inkqubo ye-isingqisho se-circadian ibhekisa kwii-oscillations ezihamba ngokuguquguquka okuthile kwebhayiloji ngexesha lekhefu eliqhelekileyo.
Isingqisho se-circadian emva koko sinento yokwenza nolandelelwano lweziganeko ezenzeka kwizinto eziphilayo ngalo lonke usuku, uqaphele ukuba indalo ayifani ngokungqongqo kuzo zonke iiyure ezingama-24.
Ikloko yebhayoloji
Kwimeko yabantu, ubukho besingqisho esijikelezayo sithetha ukuba imeko apho ubomi benzeka khona kwisininzi,ixesha lokuphumla nelinye lomsebenziAyiveliswanga kuphela ngenxa yenkcubeko kodwa ngokuchaseneyo inolwalamano oluthe ngqo kunye nendalo yomntu.
Uninzi lwee imisebenzi ebalulekileyo yomntu Bayasithobela esi isingqisho, esithetha ukuba amaxabiso abo awahlali rhoqo kodwa axhomekeke kumjikelo wemihla ngemihla abahlalutywa kuwo: iipateni zokwahluka ziphindaphindwa imihla ngemihla.
Ngamanye amaxesha xa isingqisho se-circadian yaziwa ngokudibanisa njengewotshi yebhayiloji okanye iwotshi yangaphakathi. Imvelaphi yolu landelelwano lweziganeko inokuba isuka kwi iiseli eyokuqala ngakumbi, ukukhusela ukuphindaphindeka kwe-DNA kwimitha ephezulu ye-ultraviolet, ekhoyo emini. Kukule nguqu ke apho ukuphindaphindeka kwe-DNA kwaqala ukwenzeka ebusuku, into eyayisele ikho kwizinto ezizitho zine.
- Bona kwakho: Imizekelo yesingqisho sebhayoloji
Imizekelo yesingqisho sokujikeleza
- Iingxaki ze-jet lag xa umntu kufuneka ehambele kwelinye ilizwe (jet lag).
- Obona bushushu bomzimba busezantsi ngeeyure zakusasa.
- Ubuthongo obunzulu obenzeka nge-2 kusasa.
- Ukumisa ukuhamba kwamathumbu ngo-10: 30 ebusuku.
- Ukufihlwa kweMelatonin malunga ne-9: 00 ebusuku.
- Obona bushushu bomzimba buphezulu, malunga ne-7: 00 ebusuku.
- Elona luthamba lukhulu kwezihlunu, ngo-17: 00.
- Olona lungelelwaniso luhle kakhulu emini emaqanda.
- I-spike kuxinzelelo lwegazi malunga ne-6: 00.
- Eyona mfihlo iphambili ye testosterone malunga ne-09: 00.
Ukulungiswa komjikelo
Inkqubo ye- Ixesha lomjikelo wesingqisho Kufana nobude bemini, iiyure ezingama-24: kuyinto eqhelekileyo ukuba isingqisho sihlale sizinzile kunye nexesha lelo xabiso phantsi kweemeko ezihlala zihleli.
Lo mjikelo unokuguqulwa, kodwa ngohlobo lwawo kufuneka urhuqwe, oko kuthetha ukuba xa zisenzeka inkuthazo yangaphandle Kuqhelekile ukuba iwotshi itshintshe iintsuku ezimbalwa de ibuyele esiqhelweni.
Ukongeza, kubalulekile ukuba iwotshi ejikelezayo igcine ixesha layo leeyure ezingama-24 ngaphandle kokuma kwemeko yomoya woxinzelelo kunye nobushushu, kwinkqubo eyaziwa ngokuba yimbuyekezo yeqondo lobushushu.
Isingqisho se-circadian yinkqubo eyenzeka ebantwini nakwezinye izilwanyana. Ibango lamkelwe ngokwesiqhelo lokuba kwizilwanyana eziguqukayo (ezinje ngabantu), i ixesha lewotshi elinokuphela Kukhulu kuneeyure ezingama-24 (kuyachazwa ukuba xa umntu ehlukanisiwe nendawo yakhe yangaphandle, ixesha lakhe li-24 nesiqingatha seyure), ngelixa ebusuku lingaphantsi.
Iingxaki zesigqi
Njengeendlela ezahlukeneyo zomzimba womntu, iwotshi yangaphakathi yebhayiloji inokuba nayo utshintsho kunye neengxaki. Ixesha elingaphezulu okanye elingaphantsi kweeyure ezingama-24 linokuvelisa iingxaki ezahlukeneyo ukuya kuthi ga kubomi bemihla ngemihla obucwangciselwe ukuhlala ngale ndlela, kunye nezinto eziqeqesha iwotshi yebhayoloji, njengobungakanani bokukhanya.
Eyona ngxaki ikhawulezileyo kwezi Ukuphazamiseka kukufutshane okanye ukulala ixesha elide, kodwa ngokuhamba kwexesha oku kungakhokelela kwizifo ezahlukileyo, zihlala zentliziyo.
