Zvemukati
Iyocircadian mutinhimira zvinoreva kusvibiswa kunoitika kuburikidza nemimwe misiyano yehupenyu panguva yenguva yakajairwa yenguva.
Iyo circadian mutinhimira zvino ine chekuita nekuteedzana kwezviitiko zvinoitika muhupenyu hwehusiku, tichicherekedza kuti zvakasikwa hazvina kunyatso kufanana mumaawa makumi maviri nemana.
Nguva yekuzvarwa
Panyaya yevanhu, kuvapo kwechidimbu mutinhimira zvinoreva kufunga nezve marongero ayo hupenyu anoitika kune vazhinji, ainenguva yekuzorora uye imwe yebasaIyo haina kugadzirwa chete nekuda kwetsika zvikonzero asi zvinopesana ine hukama hwakananga nehunhu hwevanhu.
Mazhinji eiyo mabasa akakosha emunhu Ivo vanoteerera uyu mutinhimira, uyo unoreva kuti hunhu hwavo hahugari asi hunotsamira padanho rezuva nezuva umo ivo vanoongororwa: iwo misiyano mapatani anodzokororwa zuva nezuva.
Dzimwe nguva apo circadian mutinhimira inozivikanwa colloquially seye wachi yekuberekwa kana wachi yemukati. Kwakatangira kuteedzana kwezviitiko kungangodaro kwakatangira mu masero zvimwe zvekare, kuitira kuchengetedza DNA kudzokororwazve kubva kune yakanyanya ultraviolet radiation, iripo masikati. Zviri kubva kushanduko iyi kuti kudzokororwa kweDNA kwakatanga kuitika panguva yehusiku, chimwe chinhu chaive chiripo muzvinhu zvine hominid.

Mienzaniso ye circadian mutinhimira
- Zvinetso zvejeti zvinosara kana munhu achifanira kuenda kune imwe nyika (jet lag).
- Iyo yakadzika tembiricha yemuviri mumaawa ekutanga emangwanani.
- Kurara kwakadzika kunoitika panenge pa 2 mangwanani.
- Kumisa ura kufamba 10:30 pm
- Kuchengetedzwa kweMelatonin kuma9: 00 dzemasikati.
- Iyo yepamusoro tembiricha yemuviri, kuma7: 00 dzemasikati.
- Musono wakanyanya kusimba, na17: 00.
- Kufambisa kwakanakisa nguva dzemasikati.
- Iyo spike muropa BP kuma6: 00.
- Yakakwirira kwazvo testosterone secretion yakatenderedza 09: 00.
Shanduko yekushandurwa
Iyo rhythmic kutenderera kwenguva Izvo, sekureba kwezuva, maawa makumi maviri nemana: zvakajairika kuti mutinhimira urambe wakadzikama nenguva yenguva iyoyo pasi pemamiriro ezvinhu.
Kutenderera uku kunogona kuchinjwa, asi nehunhu hwayo hunofanira kudhonzwa, zvinoreva kuti kana zvikaitika zvinokurudzira zvekunze Zvakajairika kuti wachi ichinje kwemazuva mashoma kusvika yadzokera kune yakajairwa.
Uye zvakare, zvakakosha kuti iyo circadian wachi ichengetedze yayo 24-awa periodicity zvisinei nemamiriro emuchadenga ekumanikidza uye tembiricha, mukuita kunozivikanwa sekubhadharwa kwetembiricha.
Iyo circadian rhythm inzira inoitika muvanhu nemimwe mhuka. Chirevo chinowanzo gamuchirwa kuti mumhuka dzinoda kufa (sevanhu), iyo endogenous wachi nguva Yakakura kudarika maawa makumi maviri nemana (zvinotaurwa kuti kana munhu akaparadzaniswa nenzvimbo yake yekunze, nguva yake ndeyemaawa makumi maviri nemana nehafu), nepo husiku iri shoma.
Zvirwere zveRhythm
Senzira dzakasiyana dzemuviri wemunhu, wachi yemukati yehupenyu inogona kuve nayo shanduko uye matambudziko. Iyo nguva yakakura kana isingasviki maawa makumi maviri nemana inogona kuburitsa matambudziko akasiyana kusvika padanho rekuti hupenyu hwezuva nezuva hwakarongedzwa kurarama nenzira iyi, pamwe nezvinhu zvinodzidzisa wachi yehupenyu, sekuwedzera kwechiedza.
Dambudziko rinonyanya kukurumidza reizvi kusagadzikana ipfupi kana kurara kwenguva refu, asi nekufamba kwenguva izvi zvinogona kutungamira kuzvirwere zvakasiyana, kazhinji zvemwoyo.
