Njengoba isikhathi esishintshashintshayo kungathinta nengozi yokuba nesifo somdlavuza?

Isikhathi zigaba, abantu abahlala kuyo, zingahlanganiswa encane anda yokuba nezinhlobo ezithile zomdlavuza, kusikisela isifundo esisha. Lo ingozi kusukela ukwephulwa of iwashi bakho abakuzalayo.

Circadian isigqi iziyaluyalu

iwashi Human yemvelo ingakhishwa ubaleka uma usebenza ebusuku, isibonelo. Ososayensi abakubiza ngokuthi yokuphazamiseka kwemikhuba lomzimba. Aye kuhlotshaniswa kwengozi yomdlavuza ngo yezisebenzi shift, ngokuvumelana Dr. uNeil Keporaso, i Uchwepheshe wezifo eziwumshayabhuqe ngaleso National Cancer Institute kanye umsunguli walokhu kucwaninga, phambili.

Nokho, izinguquko isigqi lomzimba, okuyinto nezingokwengqondo ezitholakala kubantu abasebenza amashifu, osemqoka, njengoba ziya emsebenzini emini ukusebenza ebusuku. Keporaso nethimba lakhe alalelwa semfene ezincane futhi ezicashile ku iwashi lomzimba, okungase futhi nomthelela nengozi yokuba nesifo somdlavuza.

Eqinisweni, abantu abaningi babe ukuphazamiseka elincane isigqi lomzimba ngesimo jet Lag nomphakathi. Kwenzeka uma nenza ukulala ngeviki, kodwa ukuwuchitha ibe ngempelasonto lapho awudingi ukusheshe sivuke ukuze umsebenzi.

Kodwa jet Lag zezenhlalo zingaba kwenzeke ngenxa izoni yesikhathi, wathi Keporaso.

Ngasiphi isikhathi ilanga liphuma?

Kuye umkhawuko wesikhathi, isikhathi ukuphuma nokushona kwelanga zingahluka: ukuhambisa 5 lamadigri longitude ngasentshonalanga, badabula amazoni imiphumela nesikhawu semizuzu engu-20 lapho eliphuma khona ilanga, ngokusho kocwaningo ethulwa ngo-April 2 emhlanganweni waminyaka yonke we amalungu American Association for Cancer Research. Le miphumela angakafakwa eyanyatheliswa ngo iphephabhuku peer-sibuyekezwe.

Ngokwesibonelo, uma umuntu engase aphaphame-8 ekuseni e-Boston, emgwaqeni Ungasavele khona ukukhanya. Kodwa uma uhlala e-Ohio evuka ngesikhathi esifanayo, ngesikhathi zone efanayo, iwindi zona kungenzeka zisalokhu zingenazo amnyama. Ukukhanya kwelanga "utshela" begazi iwashi indoda e-Boston, ngale kwalokho kwakusekuseni, kodwa izakhamuzi Ohio akwenzeki uma evuka. Lokhu kuholela dissonance phakathi nesikhathi on iwashi kanye newashi lomzimba.

jet Social lag kuye kwahlotshaniswa izimo ezihlukahlukene, kuhlanganise ukukhuluphala nesifo sikashukela. Esifundweni entsha, abacwaningi baye alalelwa umdlavuza.

Umdlavuza kanye newashi lomzimba

Abacwaningi ihlaziye idatha kusuka abadala 4 kwesigidi abaye unomdlavuza phakathi kuka-2000 no-2012. Abantu kulolu cwaningo wahlala 11 uthi ngaphakathi ezwekazini lase-United States.

Imiphumela yabonisa ukuthi yonke 5 lamadigri longitude kusukela empumalanga kuya entshonalanga ngaphakathi izoni yesikhathi efanayo, ingozi yokuba yiluphi uhlobo lomdlavuza kukhuphuke ngo-3 kumaphesenti ayi amadoda futhi 4 - kwabesifazane.

Abacwaningi bahlola ingozi yokuba nezinhlobo ezithile zomdlavuza. Ngokwesibonelo, abantu ababehlala esifundeni esentshonalanga umkhawulo wesikhathi, kwadingeka basengozini engamaphesenti angu-4 nomdlavuza wendlala yabesilisa, futhi amaphesenti angu-13 - of ezingamahlalakhona wegazi lymphocytic (a umdlavuza esithinta amangqamuzana amhlophe egazi), uma kuqhathaniswa nalabo ababehlala empumalanga kakhulu ingxenye yeskhati.

Abesifazane abahlala ezindaweni esentshonalanga izoni yesikhathi, babe nengozi amaphesenti 4 nomdlavuza webele ngokuthi 12 per cent - of ezingamahlalakhona wegazi lymphocytic, futhi amaphesenti angu-10 - umdlavuza lesizalo, uma kuqhathaniswa nalabo ababehlala kule ndawo esempumalanga izoni yesikhathi efanayo , abacwaningi bathola.

Zonke lezi ukwanda ingozi yomdlavuza kuncane, futhi ososayensi bathi ucwaningo kudingeka okwengeziwe ukuze kutholakale ukuthi kukhona ukuhlobana esiyimbangela phakathi umdlavuza futhi ukwephulwa iwashi lomuntu begazi.

izizathu

Mechanism ezingaba uxhumano nomsebenzisi isigqi lomzimba kanye nomdlavuza ayikaziwa. Nokho, kungase kube noshintsho samuva nje empilweni zabantu nsuku zonke.

Kukho konke ukuphila kwakhe Emhlabeni usuku womuntu nsuku zonke kwakuhambelana nokuka ukuhamba kwelanga. Abantu babekhona emini futhi ukuphumula ebusuku. Kodwa kungazelelwe sekushintsha konke. Abantu bahlale ezindlini emini bavezwa ukukhanya ebusuku. Lokhu kungaholela yehlise amazinga melatonin. Kungenzeka ukuthi amazinga melatonin aphansi kungathinta izivikeli mzimba, kanye kwengozi yomdlavuza kubantu.

Nakuba ucwaningo kudingeka okwengeziwe Keporaso uthi cishe yilowo nalowo phakathi kwethu ungazuza ukukhanya yemvelo emini futhi ngokunciphisa kukhanyiswe yikona ebusuku.
