La ungcoliseko lwengxolo ebusuku Iqala ukuba yindawo ephambili phakathi kwezinto ezisongela impilo yentliziyo eYurophu. Uphando olunzulu lubonise ukuba ingxolo yezithuthi ngexesha lokuphumla, nokuba ayikhathazi kangako, inxulunyaniswa nokwanda kwe I-cholesterol ye-LDL kunye nezinye ii-lipids zegazi.
Olu lwalamano phakathi Ingxolo yetrafikhi yasebusuku kunye neprofayili ye-lipid Oku akuyonto incinci: idatha ibonisa ukuba izigidi zabantu kwiindawo zasezidolophini nakwiindawo zasezidolophini zaseYurophu basenokuba bahlangabezana notshintsho kwindlela umzimba osebenza ngayo ngaphandle kokuqaphela, ngenxa nje yengxolo abayinyamezelayo xa belele.
Uphononongo olukhulu eYurophu: iqala nini ingozi?
Uphando luhlalutye okungaphezulu 270.000 abadala evela kumazwe aliqela aseYurophu, isampulu engaqhelekanga ngenxa yobukhulu bayo kunye nokwahlukahluka kwayo. Olu phononongo ludibanise idatha evela kumaqela amakhulu amathathu: UK Biobank, i Uphononongo lwaseRotterdam kunye Iqela Lokuzalwa LaseMantla eFinland lika-1966Oku kusivumele ukuba sifumane umfanekiso oqinileyo wempembelelo yengxolo yasebusuku kwiimeko ezahlukeneyo kakhulu.
Ngokweqela elikhokelwa ngu Yiyan HeNgokutsho kweYunivesithi yase-Oulu, umda wokukhathazeka usondele Iidesibeli ezingama-50 (dB)Ngaphantsi kwelo nqanaba, akukho tshintsho lucacileyo olubonwe kwiiprofayili ze-lipid, kodwa utshintsho lwaqala ukubonwa ngaphezulu kwe-50 dB. ukunyuka okuqhubekayo kwe-cholesterol ye-LDL kunye nezinye iinxalenye ezinxulumene nomngcipheko wentliziyo.
Abathathi-nxaxheba babekwe ngokwamaqela ngokwengxolo yezithuthi emakhaya, ukusuka ngaphantsi kwe-45 dB ukuya kwi-55 dB nangaphezulu ebusuku. Xa kuthelekiswa neqela elingachaphazelekanga kakhulu, kwabonwa ukuba kuluhlu lwe 50 ukuya kuma-55 dB Ukunyuka okulinganiselweyo kwe-LDL kunye nezinye ii-lipoproteins ezingaziwayo kangako kwakusele kusenzeka, kwaye olu hlobo loxinzelelo lwalusiya lubonakala ngakumbi. ngaphezulu kwe-55 dB.
Nangona ukunyuka okuphakathi kwe i-cholesterol epheleleyo yayijikeleze 0,41 milligrams ngedesilitha nganyeNangona eli nani lisenokubonakala lingabalulekanga kumntu ngamnye, impembelelo edibeneyo ibaluleke kakhulu ngenxa yenani elikhulu labantu abahlala bephantsi kwale ngxolo yasebusuku.
Zeziphi iinguqu ezibonwe kwi-cholesterol?
Uhlalutyo lubonise ukuba iqela eliphambili elichaphazelekayo yayili I-cholesterol ye-LDLI-cholesterol ye-LDL, eyaziwa kakhulu ngokuba yi-"cholesterol embi" ngenxa yolwalamano lwayo olusondeleyo nokwakheka kwe-plaque kwimithambo yegazi, ibonise indlela efanayo kuzo zonke ii-cohorts ezintathu ezihlalutyiweyo: ingxolo ephezulu yezithuthi ebusuku yayinxulunyaniswa namanqanaba aphezulu e-LDL.
Ukongeza kwi-LDL, kukho ukwanda kwamanqanaba e-LDL. i-cholesterol iyonke kunye namasuntswana e-IDL (ii-lipoproteins eziphakathi koxinano), ezikwanxulunyaniswa nomngcipheko okhulayo wesifo sentliziyo. Ezi ziphumo ziphindaphindwe kuwo onke amazwe amathathu aqukiweyo, ziqinisa amandla onxibelelwano phakathi kokuvezwa kwengxolo ebusuku kunye notshintsho kwimetabolism ye-lipid.
Ingongoma ebalulekileyo kukuba olu phononongo alufumananga budlelwane phakathi kwengxolo yasebusuku kunye I-cholesterol ye-HDL (oko kubizwa ngokuba “yi-cholesterol elungileyo”) okanye triglyceridesNgamanye amazwi, isiphumo sengxolo sibonakala sicacile kwiindawo ezithile zeprofayili ye-lipid, endaweni yokutshintsha zonke izalathisi ngokulinganayo.
Abaphandi bakwaqaphele ukuba olu nyuko lwe-LDL beluhlala luhleli kungakhathaliseki ukuba isini, ubunzima bomzimba, okanye inqanaba lemfundo Ngale ndlela, ingxolo yasebusuku ivela njengengxaki engalindelekanga kwezinye iimpawu zomntu okanye zentlalo nezoqoqosho.
Indlela impembelelo yengxolo kunye ne-lipids elinganiswe ngayo
Ukuqikelela ukuba umntu ngamnye usesichengeni ingxolo yendlela ngexesha lokulalaKusetyenziswe iimaphu zelizwe zengxolo ezijikeleze umhlaba, ezirekhoda amanqanaba esandi kwiindawo ezahlukeneyo zokuhlala. Ezi maphu zazibhekiselwe kwiidilesi zabathathi-nxaxheba, nto leyo evumela umntu ngamnye ukuba anikwe inqanaba eliqikelelweyo le-decibel elifumaneka emakhayeni akhe ebusuku.
Ngaxeshanye, oku kulandelayo kwahlalutywa iisampuli zegazi kusetyenziswa i-nuclear magnetic resonance, indlela ekwaziyo ukuvavanya ukuya kuthi ga Iindidi ezili-155 zamafutha, iiproteni, kunye nezinye iimolekyuli ikhona emzimbeni. Le ndlela iphezulu inike umfanekiso oneenkcukacha ezininzi ngeprofayili yamafutha yomntu ngamnye, ngaphaya kwe "cholesterol iyonke" eqhelekileyo edla ngokubonwa kuhlalutyo oluqhelekileyo.
Abaphandi basebenzise uhlengahlengiso oluninzi lwezibalo ukuzama ukwahlula indima ethile yengxolo. ukumoshwa komoya, isalathisi sobunzima bomzimba, ubukho be ukutshayaisondo kunye ekufundeni, ukuze kuthintelwe ezi zinto ekuphazamiseni unxibelelwano phakathi kwesandi sasebusuku kunye ne-cholesterol.
Emva kokusebenzisa ezi ndlela zokulawula, ubudlelwane phakathi Ukuvezwa kubushushu obungaphezulu kwama-50 dB ebusuku kunye nokwanda kwe-LDL Yahlala iqinile, ithetha ukuba ingxolo inefuthe layo, kwaye ayisiyonto nje ebonakalisa ezinye iimeko zendalo okanye zendlela yokuphila.
Indima yokulala kunye ne-cortisol kolu lwalamano
Umbuzo omkhulu kukuba yeyiphi indlela echaza ukuba kutheni indawo enomsindo ebusuku iguqulela ekubeni yi-cholesterol ephezulu ye-LDL. Olu phononongo lukhomba ikakhulu kwi ukuhlukana kokulala okubangelwa ziindlela zokuhamba. Nangona umntu ehlala engavuki ngokupheleleyo, ingxolo ibangela ukuphazamiseka okuncinci okuphazamisa ukuqhubeka kwezigaba zokulala.
Ezi nguqu-ncinci ziphindaphindwayo zivuselela iindlela zokuphendula koxinzelelo lomzimbaKwimeko enjalo, cortisol, i-hormone ekhutshwa ngokuchanekileyo ukunceda umzimba ukuba ujongane neemeko ezixinzelelekileyo kwaye, phakathi kweminye imisebenzi, ilawula imetabolism yamafutha kunye ne-cholesterol.
Xa ezi ziphazamiso zokulala ziphindaphindwa ubusuku ngabunye, inkqubo yoxinzelelo igcinwa ikwimeko "yengxolo yangasemva," enokuthi ekuhambeni kwexesha itshintshe indlela umzimba olawula ngayo ii-lipids. Ngale ndlela, ingxolo yasebusuku iba sisizathu esingapheliyo sokuba inyusa amanqanaba e-LDL ukuya phezulu kunye nezinye ii-lipoprotein ezinxulumene nomngcipheko wentliziyo.
Ngamafutshane, ukulala kwindawo enengxolo, nokuba ucinga ukuba "uyayiqhela" kwaye ayikuvusi, kunokubangela ukuthontsiza okuqhubekayo koxinzelelo lomzimba oluya kuthi ekugqibeleni lube yingozi entliziyweni nakwimithambo yegazi.
Ingozi engathethiyo kwizixeko zaseYurophu
Idatha ye I-Arhente yokusiNgqongileyo yaseYurophu Amanani akhankanyiweyo kuhlalutyo anika umbono wobukhulu bengxaki: ngeenxa zonke I-15% yabemi basezidolophini EYurophu, ngo-2020 abantu bachanabeke kumanqanaba engxolo ebusuku. 50 dB okanye ngaphezuluOko kukuthi, izigidi zabantu zihlala ubusuku ngabunye kuloo luhlu apho utshintsho kwi-cholesterol luqala ukubonwa khona.
Kwiindawo ezininzi zedolophu, iindlela ezijikelezayo, iindlela ezinkulu, kunye nezitalato ezixakekileyo zihamba kwiindawo zokuhlala, ngoko ke ingxolo yesithuthi Ihlala ikho. Kwabo bahlala kufutshane nezi ziseko, indawo engqonge ingxolo ebusuku ingaba yinto engaqhelekanga. umngcipheko wentliziyo zibalulekile njengokutya okanye icuba, kodwa kunzima kakhulu ukuzilawula kumntu ngamnye, ngoko ke banokucinga usetyenziso lwengxolo emhlophe njengenyathelo elincedisayo.
Kwiindawo ezininzi zedolophu, iindlela ezijikelezayo, iindlela ezinkulu, kunye nezitalato ezixakekileyo zihamba kwiindawo zokuhlala, ngoko ke ingxolo yesithuthi Ihlala ikho. Kwabo bahlala kufutshane nezi ziseko, indawo engqonge ingxolo ebusuku ingaba yinto engaqhelekanga. umngcipheko wentliziyo kubaluleke njengokutya okanye icuba, kodwa kunzima kakhulu ukulawula umntu ngamnye.
Olu phononongo luchasa imbono yendabuko eyayithi i-cholesterol engaphezulu ibangelwa kukutya, ukungazilolongi, okanye ufuzo. Ngaphandle kokunciphisa ukubaluleka kwezi zinto, iziphumo zibonisa ukuba isandi sasezidolophini Ikwadlala indima ebalulekileyo kwimpilo yemithambo yegazi.
Le ndlela ivula ithuba lokuqwalasela ungcoliseko lwengxolo ebusuku njengenjongo ephambili yemigaqo-nkqubo yezempilo yoluntu kunye nocwangciso lwedolophu, kwinqanaba elifanayo nelo sele ligcwele ungcoliseko lomoya okanye ukukhuthaza imikhwa yokuphila esempilweni.
Impembelelo kwimpilo yoluntu nakubomi bemihla ngemihla
Nangona ukunyuka okuqhelekileyo kwe-cholesterol iyonke kunokubonakala kuncinci kumntu ngamnye, ukubaluleka kokwenene kuvela xa ingxaki ijongwa ngokwembono yabantu bonke: ukunyuka okuncinci kwizigidi zabantu kunokuthetha inani elikhulu labantu. iziganeko ezongezelelweyo zentliziyo kuluntu ngokubanzi.
Kwiziphathamandla zempilo zaseYurophu, ezi ziphumo ziqinisa imfuneko yokubandakanya Ingxolo yendlela ebusuku kwizicwangciso zokuthintela isifo sentliziyo. Amanyathelo anje ngemida yesantya kwiindawo zasezidolophini, ukuyila ngokutsha iindlela ezixineneyo zezithuthi, ukuphucula ukhuseleko lwesandi emakhaya, okanye ukudala "iindawo ezizolileyo" kunokuba nefuthe impembelelo ngqo kwi-cholesterol kwaye, ngokwandisa, kumngcipheko wokuhlaselwa sisifo sentliziyo kunye nezinye izifo zentliziyo.
Ngokomntu ngamnye, abo bahlala kufutshane neendlela ezixakekileyo banokucinga ngezinye izisombululo zasekhaya, ezinje ngokuphucula iifestile neengcango, ukusebenzisa iiblinds okanye amakhethini aneempawu zokuthintela ubushushu, ukusebenzisa ii-earplugs, okanye ukuphinda bahlele indawo yabo yokuhlala ukuze babeke amagumbi okulala kwiindawo ezizolileyo kangangoko. Ezi azizozisombululo zigqibeleleyo, kodwa zinokunceda. ukunciphisa kancinci ukuvezwa ebusuku kwingxolo. Sebenzisa ii-earplugs Kungaba lukhetho olusebenzayo kwiimeko ezininzi.
Nokuba kunjalo, umyalezo odluliselwa yile ncwadi ucacile: indawo evakalayo esilala kuyo ayisiyonto nje engqongileyo, kodwa yinto enokwenza ukutshintsha ngokulinganisela ikhemistri yegazi lethuKwilizwekazi elihlala ezidolophini njengeYurophu, ukwamkela le nyaniso kuvelisa umngeni owongezelelekileyo ekulweni nezifo zentliziyo.
Xa zizonke, ubungqina besayensi obukhoyo bubonisa umfanekiso apho ingxolo yendlela yasebusuku isebenza njengento ebangela umngcipheko wentliziyo engathethiyo kodwa engaguqukiyo, ekwaziyo ukunyusa i-LDL cholesterol kunye nezinye ii-lipoproteins kwizigidi zabantu baseYurophu, okwenza ulawulo lwendawo evakalayo ebusuku lube ngundoqo, nangona lusalindile, kwimigaqo-nkqubo yezempilo yoluntu.
