Indawo yeBongo Ilawula ixesha lokulala, Ukuvuka, Ukushisa, kunye neeHormones
Yintoni i-nucleus ye-suprachiasmatic (SCN)? Funda nge-anatomy yale ndawo yengqondo kwindawo ye-hypothalamus kunye nendlela i-SCN ilawula ngayo ukulala komzimba kwaye ivule iipatheni kunye nokushisa, imetabolism, kunye ne-hormone release. Fumana oko kwenzekayo ukuba i-SCN ibonakaliswe kwaye yintoni enye impawu ebalulekileyo.
ILizwi kwiRhythms Rhythms
Kukho iinkqubo ezininzi zangaphakathi ezichaphazela ngaphandle kwimeko yethu.
Umhlaba unemizuzu engama-23 kunye nomzuzu-56 wemijikelezo yemihla ngemihla ehlinzeka ngamaphetheni aqikelelweyo okukhanya kunye nobushushu, ukutya kunye nomsebenzi wesidlo. Ngenxa yokuziphendukela kwemvelo, le meko ithintela imetabolism kunye nokuziphatha malunga nenyama yonke emhlabeni, kuquka abantu. Ixesha le- circadian lichaza malunga neeyure ezingama-24 zeeyure ezenziwe ngokuzimeleyo kwezi mpembelelo zangaphandle. Kubantu, ezinye zeenkqubo zangaphakathi ezichanekileyo ezingapheliyo zibandakanya:
- Ukulala nokuvuka
- Metabolism
- Iqondo lokushisa lomzimba
- Ma Cortisol
- Amazinga eMelatonin
- Amanye amahomoni
Kukhona intsebenziswano phakathi kwewashi yomzimba yangaphakathi kunye neengxelo zesikhathi sangaphandle. Amancuba amaninzi emzimbeni aya kulandela umzekelo we-circadian, kunye nomququzeleli oyintloko oyindawo engqondweni ebizwa ngokuba yi-nucleus ye-suprachiasmatic.
Yintoni i-Nucleus Suprachiasmatic ye-Brain's Hypothalamus?
I-nucleus ye-suprachiasmatic ikhona kwingingqi ehamba phambili yengqondo ebizwa ngokuba yi- hypothalamus .
Iqulethe iqela leeseli zeentsimbi (okanye i-neurons) ezilawula isigqirha somzimba wakho. I-nucleus ye-suprachiasmatic ihlala kwindlela engacacanga ngayo i-optic chiasm, apho iimbulunga zisuka kwiso nganye ukuya kwi-cross cross, kwaye ngoko ke ithonyelwa kakhulu ngongoma wokukhanya.
Indima ye-SCN kwi-Sleep Normal ne-Circadian Rhythms
Ukukhanya ngumlawuli obalulekileyo kumzimba we-circumcadian rhythms.
Kufunyanwe kwiso ngeli-receptors ezibizwa ngokuba ngama-cellinitive retinal ganglion cells (ipRGC) eziqukethe i-photopigment melanopsin. Kukho uxhulumaniso olubizwa ngokuba ngumzila we-retinohypothalamic osukela kwi-retina yelihlo ukuya kwi-hypothalamus yangaphambili. Kwi-hypothalamus ihlala kwi-SCN, i-pacemaker yomzimba (okanye iwashi ye-master).
Iziphazamiso zokulala ze-circadian ziyakwenzeka xa i-synchrony phakathi komzimba kunye nemeko yangaphandle ilahlekile. Iipatheni zokulala nokuvuka zingasayi kuhambelana nemimiselo yoluntu. Ezi meko ziquka:
- Isifo sesifo sokulala esilahlekile
- Isigulane sesigaba sokulala esiphezulu
- Ukusebenza ngokukhululeka ( okungengowesi-24 )
- I-rhythm engavaliyo yokulala
Ezi meko zenzeka ngezizathu ezininzi. Abanye abantu abanesigaba sokulala esibambezelekayo bahlelwe ngokwemfuyo ukuba babe nokuchithwa kwe-circadian, kunye nemeko esebenza kwiintsapho kunye nokuqala ebusheni. Ezi ngxaki zingadlukiswa ngokukhetha kweendlela zokuphila, kubandakanywa iipatheni zokulala ezingaqhelekanga okanye ukungafaneli okanye ukukhanya ngokukhawuleza kokukhanya. Kwakhona kunokwenzeka ukuba imeko ephazamisayo, ukulimala, okanye ezinye izimbangela zokufaka isandla ekuphuhliseni ingxaki ye-circadian.
Yintoni eyenzekayo xa i-Nucleus yeSuprachiasmatic ibonakaliswe?
Ekuqwalaseleni umendo ovela ekuboneni ukukhanya kummandla we-SCN, kunokwenzeka ukuba umonakalo uvele kwiindawo ezininzi.
Abantu abangaboniyo ngokupheleleyo, abanakho ngokupheleleyo ukujonga ukukhanya, bangaphuhlisa ii-Non-24. Kwimeko yeemeko eziphazamisayo ezifana nesifo se-Alzheimer, ngokukodwa abo bahlala kwiziko elifana nekhaya labahlengikazi, i-rhythm ingavamile yokulala. I-trauma, i-stroke, okanye i-tumors inokuchaphazela i-SCN kwaye ibangele ukungasebenzi kwayo.
Xa i-pacemaker esemzimbeni yomzimba ibonakaliswe kwaye umsebenzi wayo uhlaselwa, iwashi zepheripha zilahlekelwe ngumlawuli wazo. Isikhathi sokukhululwa kwe-hormone, ukutshatyalaliswa kwe-metabolism kunye nezinye iinkqubo kunokuphazamiseka. Kukho uphando olusakhulayo olubonisa ukuba oku kunokuba negalelo kwizifo ezahlukahlukeneyo.
Ezinye izibonakaliso zexesha zingabaluleka. Kwiimfama, umthamo ophantsi we- melatonin ngokuhlwa ungadingeka. Ngaphandle koko, ukusetyenziswa kweHetlioz kungaboniswa. Ixesha lezenzo zentlalo, ukuzivocavoca, ukutya, ukushisa kwendalo, kunye neendawo zokulala zingathabatha inxaxheba ebalulekileyo ekuthinteleleni ixesha lokusebenza kweenkqubo zangaphakathi.
ILizwi
Ukuba unenkxalabo yokuba unokufumana ingxaki ye-circadian, qalisa ngokuthetha ne-sleeping specialist. Unokuyihlolisisa iimpawu zakho kwaye ufumane unyango olululo oluza kukunceda ulale ubusuku obukhulu kwaye uzive ungcono emini.
