AKAWEDZERA ZVIMWE ZVIMWE ZVIMWE ADRENALINE MUVASINA KUSVIRA?
Chekutanga pane zvese, zvakakosha kujekesa kuti iyo American Heart Association haina kunyatso pro-vaping. Zvakawanda zvinoburitswa mumapepanhau pamusoro pefodya yemagetsi yakatove yakarongwa na kusangana.
Maererano netsvagiridzo itsva yakabudiswa mujenari " The American Heart Association", vasina kuputa vane hutano vanogona kuwedzera mazinga eadrenaline mumoyo mushure mekuputika nicotine e-liquid. Zvechokwadi, adrenaline inotakurwa neropa, inoita zvakananga pamwoyo. Kurova kwemoyo wake kunowedzera asi izvi dzimwe nguva zvinogona kusvika pakukonzera tachycardia nekuti moyo uri kumhanya.
Holly R. Middlekauff, munyori anotungamirira uye purofesa wemishonga (cardiology) paDavid Geffen School of Medicine paUCLA anoti, Nepo e-fodya kazhinji inopa mashoma ecarcinogens pane ayo anoonekwa muutsi hwefodya, anopawo nicotine. Vakawanda vanodavira kuti tara kwete chikakananda ndicho chinoita kuti pave nengozi yekenza uye yemwoyo »
Kuti vazvimise pane zvinogona kusakuvadza zvevaping, Muzvinafundo Middlekauff nechikwata chake vakashandisa nzira inonzi "kurova kwemoyo" yakawanikwa kubva mukurekodhwa kwenguva refu uye kusingapindike kwekurova kwemoyo. Kuchinja kwemoyo kunoverengerwa kubva padanho rekusiyana-siyana panguva iri pakati pekurova kwemoyo. Kusiyana uku kunogona kuratidza huwandu hweadrenaline pamwoyo.
Iyi chiyero chemoyo chekuchinja kwemoyo yakashandiswa mune zvimwe zvidzidzo kubatanidza kuwedzera adrenaline mumoyo nekuwedzera kwengozi yemoyo.
Maererano naProfessor Middlekauff, ichi ndicho chidzidzo chekutanga chinoparadzanisa nicotine kubva kune zvimwe zvikamu kuitira kuti vaone kushanda kwefodya yemagetsi pamwoyo wemunhu.
Pamazuva akasiyana, mumwe nemumwe aitora fodya akashandisa e-fodya ine nicotine, e-fodya isina nicotine, kana imwe yekuenzanisa mudziyo. Vatsvakurudzi vakayera cardiac adrenaline basa nekuongorora kuchinja kwemwoyo uye kushungurudzika kwehutano mumasampuli eropa nekuongorora plasma enzyme paroxonase (PON1).
NICOTINE AKAFUMWA HAHAI KUVADZA KANA KUKONZERA!
Kuratidzwa kwemhepo kune nicotine kwakaguma nekuwedzera kwemazinga eadrenaline mumoyo, sezvinoratidzwa nekusagadzikana kwekushaya kwemoyo.
Oxidative kusagadzikana, iyo inowedzera njodzi yeatherosclerosis uye kurwisa kwemoyo, yakaratidza hapana shanduko mushure mekuratidzwa kune e-fodya ine uye isina nicotine. Kuna Muzvinafundo Middlekauff, kana huwandu hwemakaka akadzidzirwa oxidative kusagadzikana hwaive hushoma, zvimwe zvidzidzo zvekusimbisa zvinozodiwa.
« Kunyange zvichinyaradza kuti izvo zvisiri-nicotinic zvikamu hazvina mhedzisiro iri pachena pamazinga eadrenaline mumoyo, mhedzisiro iyi inokanda kupokana papfungwa yekuti inhaled nicotine haina kunaka kana yakachengeteka. Chidzidzo chedu chakaratidza kuti acute e-cigarette kushandiswa ne nicotine kunowedzera cardiac adrenaline mazinga. Sezvo chiyero chemoyo adrenaline chakabatana nenjodzi yakawedzera kune varwere vakaziva chirwere chemoyo uye kunyangwe kune varwere vasina kuzivikanwa chirwere chemoyo, ndinofunga izvi zvine chekuita uye zvingave zvinodiwa kuodza moyo vasingaputa kushandisa fodya yemagetsi.".
Maererano naye, fodya yemagetsi, sezvinhu zvose zvefodya, inokonzera njodzi. Nezve zvidzidzo zvenguva yemberi, vanofanira kutarisa zvakanyanya pakushungurudzika kweoxidative panguva yekushandiswa kwe-e-cigarette vachishandisa nhamba huru yezviratidzo zvemwoyo ine vanhu vakawanda.
