Njengoko ixesha imimandla zingachaphazela ingozi yokuba nomhlaza?

iindawo Ixesha, apho abantu abahlala, ibe ezinxulumene kunye nengozi encinci zokuphuhlisa iintlobo ezithile zomhlaza, icebisa isifundo esitsha. Le nto ingozi ukusuka nokuhluthwa wotshi bakho bemvelo.

ukuphazamiseka rhythm lomzimba

clock Human zebhayoloji wayebaleke ukuba isebenza ebesebenza ebusuku, umzekelo. Iinzululwazi zizibiza izifo lomzimba ezinjalo. Baye ezinxulumene kwandisa amathuba ngumhlaza abasebenzi shift, ngokutsho Dr. Neil Keporaso, i sezifo kwiNational Cancer Institute kunye umbhali owayephambili kolu phando.

Nakuba kunjalo, utshintsho izingqisho lomzimba, ezo ezifunyanwa ngabantu abasebenza kwiinguqu, ezingundoqo, njengoko baye emsebenzini emini ukuba ukusebenza ebusuku. Keporaso kunye neqela lakhe ingqalelo izitenxo ezincinane yaye inobuqhophololo ngaphezu ewotshini eziphilayo, nto leyo nayo negalelo ingozi yokuba nomhlaza.

Eneneni, abantu abaninzi baye ukuphazamiseka amancinci isingqisho lomzimba ngohlobo lag jet loluntu. Oku kwenzeka xa unamathele ukulala iveki, kodwa kuyiqhekeza njengokuqhekeka ngempelaveki ibe xa kufuneka avuke kwangoko ngenxa yomsebenzi.

Kodwa jet lag loluntu kwakhona zenzeka ngenxa izowuni yexesha, wathi Keporaso.

Xesha liphi ilanga liphume?

Kuxhomekeka ngokwezowuni yexesha, ixesha ukuphuma kwelanga ingahluka: ukuhambisa degrees 5 yeside ngasentshonalanga ngokusebenzisa imimandla ixesha iziphumo imizuzu engama-20 kweli ekuphumeni kwelanga, ngokutsho isifundo thaca kwi-Epreli 2 kwintlanganiso yonyaka amalungu American Association for Cancer Research. Ezi ziphumo ziye okwangoku ishicilelwe kwijenali peer-kwakhona.

Umzekelo, ukuba umntu uvuka ngentsimbi yesi-8 kusasa e Boston, Esitalatweni sele ukukhanya. Kodwa ukuba uhlala e-Ohio uvumbulula phezulu ngexesha elinye, kummandla xesha, le window isese mnyama. Kwelanga "wazisa" iwotshi umntu lomzimba e Boston, kwakusa, kodwa abahlali Ohio alwenzeki xa uvuka. Oku kukhokelela dissonance phakathi ixesha kule wotshi kunye iwashi eziphilayo.

jet Social lag iye yanxulunyaniswa iimeko ezahlukeneyo, kuquka ukutyeba seswekile. Kwisifundo esitsha, abaphandi baye banikela ingqalelo nomhlaza.

Umhlaza ne wotshi eziphilayo

Abaphandi lahlaziya data evela abadala 4 million abaye unesifo somhlaza phakathi 2000 no-2012. Abantu kuphononongo wayehlala 11 ithi ngaphakathi United States zwekazi.

Iziphumo zabonisa ukuba zonke izidanga-5 yeside ukusuka empuma kuye entshona ngaphakathi kummandla ngexesha elinye, amathuba ekuphuhliseni naluphi na uhlobo lomhlaza bande nge-3 pesenti ebantwini ibe yi-4 - kwabasetyhini.

Abaphandi ziviwa ingozi yokuba iintlobo ezithile zomhlaza. Umzekelo, abantu ababehlala kummandla wasentshona ngokwezowuni yexesha, yaba umngcipheko-4 ekhulwini enkulu wokuhlaselwa ngumhlaza womlomo yesinye, no-13 pesenti - wegazi ezingapheliyo lymphocytic (a umhlaza ochaphazela iiseli ezimhlophe zegazi), xa kuthelekiswa nabo ababehlala kwimpuma kakhulu yinxalenye ngokwezowuni yexesha.

Abafazi abahlala kwimimandla esentshona ngokwezowuni yexesha, baba umngcipheko 4 ekhulwini ephezulu umhlaza webele nge-12 pesenti - wegazi esingapheliyo lymphocytic, no-10 pesenti - umhlaza zesibeleko, xa kuthelekiswa nabo ababehlala kwindawo yempuma izowuni yexesha esifanayo , abaphengululi bafumana.

Zonke ezi ukwanda umngcipheko nomhlaza mancinane kakhulu, yaye izazinzulu bathi uphando okungakumbi ukuze ukuqinisekisa ukuba ngaba kukho unxibelelwano kobude phakathi umhlaza kunye ukunyhashwa wotshi yabantu eziphilayo.

izizathu

Indlela leyo Unga bophelela izingqisho lomzimba kunye nomhlaza uhlala ayaziwa. Noko ke, kusenokuba utshintsho yakutshanje noko kubomi babantu bemihla ngemihla.

Kubo bonke ubomi bakhe on Earth yabantu yosuku imihla obabulingana ukuhamba kwelanga. Abantu ababekhona emini kunye emini nasebusuku. Kodwa ngequbuliso yonke into yatshintsha. Abantu bahlale ezindlini ngexesha lasemini zibethwa ukukhanya okuqaqambileyo ebusuku. Oku kunokukhokelela kumanqanaba yehlise melatonin. Kungenzeka ukuba amanqanaba melatonin asezantsi inokuyichaphazela inkqubo yomzimba yokuzikhusela, kwakunye nengozi yokuba nomhlaza ebantwini.

Nangona uphando olunye Keporaso uthi mhlawumbi sonke sinokuzuza ukukhanya kwendalo emini ngokunciphisa ukulayita ebusuku.
