# Wasayansi: Dzuwa limachepetsa thupi

Zambiri zaposachedwa kwambiri kuchokera pa dzuwa ndi zomwe: ngakhale titaganizira kuti ultraviolet imayambitsa khansa yapakhumi, thanzi lonse laumoyo limakulitsa zoopsa izi molimba mtima. Chifukwa chake, tidzazindikira.

Tsopano dzuwa limatchulidwa kwambiri ndi zopindulitsa zambiri komanso zoteteza. Dzuwa ladzuwa limathandizira kuthana ndi kunenepa kwambiri, kupewa mtima, mphumu ndi ziphuphu zingapo. Zatsimikiziridwanso kuti dzuwa limawonjezera libido ndikusinthasintha. Ndipo mfundo pano siili zochulukira mu vitamini d, zomwe ndizofunikira pakutha kwa mafupa ndi mano ndipo zimathandiza kupewa khansa ya m'matumbo, koma m'matumbo amadzipangira okha.

Tsopano asayansi apeza chitsimikiziro kuti thupi limatulutsa nitrogen o oxide, yomwe imakhala ndi phindu pa mtima wawo ndipo imakhudzidwa ndi serotonin.

Kusowa kwa dzuwa kumakhala koyipa ngati kusuta.

Phunziro latsopano limatengera chidwi kwa azimayi 30,000 ku Sweden. "Dzuwa" logwira "linamwalira nthawi zambiri kwazaka makumi awiri. Pakati pa zomwe adaziwona zidachepetsedwa kwambiri ndi kuchuluka kwa matenda a mtima ndi matenda omwe siogwirizana ndi oncology. Dr. Pel Lindquist, akuchita phunziroli, adapeza kuti anthu omwe sasuta fodya komanso osasuta anali ofanana ndi osuta fodya, wopanikizika ndi mowa.

Anthu okalamba amafunikira dzuwa lochulukirapo.

Katswiri wa Dermato wa Richard Woller kuchokera ku yunivesite ya Edinburgh adasindikiza foni kwa okalamba kuti akhale padzuwa. Gulu la asayansi, limodzi ndi Weller, linamaliza kuti kukhalabe padzuwa kumachepetsa kuthamanga kwa magazi ndipo, chifukwa chake, kumachepetsa nkhawa ya mtima.

Dzuwa limathandizira kulimbana ndi njira yotupa.

Asayansi ochokera ku Cambridge adazindikira kuti mapangidwe a mapangidwe a cell amapanga kakhalidwe kameneka kameneka ndi kuteteza kwa munthu amathandizira nthawi yachilimwe.

Dzuwa limathandizira kukhalabe mu mawonekedwe ndipo musakhale ndi mafuta

Asayansi ochokera ku Southempton ndi Edinburgh adanena kuti kuwala kwa dzuwa kumathandizanso kukhalabe mawonekedwe. Mapeto awa adafika atayesedwa ndi mbewa, zomwe zimasungidwa pazakudya zapamwamba kwambiri ndipo zidawonekera kwa ultraviolet.

Zotsatira zake zidawonetsa kuti Ultraviolet imatsutsana ndi kukula kwa kunenepa kwambiri komanso matenda a mtundu wachiwiri. Malingaliro amatengera zotsatira za nayitrogeni yemweyo oxide, osapangidwa ndi insulini sapangidwa bwino ndipo matenda ashuga amakhala.

Kuyesera kwina chifukwa cha dzuwa pathanzi laumoyo kumachitika ku United States pogwiritsa ntchito satellite, chomwe chimasungabe kuwala kwa dzuwa komwe kunalandira anthu 16,000 kwa zaka 15 zowona. Zotsatira zake zinali ku Yunivesite ya Alabami ndipo adazindikira kuti iwo omwe adakhala nthawi yambiri padzuwa sangakhale ndi matenda a mtima.

Komanso kuyankhidwa kunalandiridwa, bwanji padzuwa timakhala osangalala. Chowonadi ndichakuti kuchuluka kwa dzuwa kumalimbikitsa masensa pa retina, komwe kumayambitsa kusokonekera kwathu, panthawi yomwe imapangidwa ndi Melalatonin, mahomoni kugona. Ndipo kulephera kwa Melatonin kumachitika chifukwa cha kukhumudwa komanso matenda a Alzheimer ndi Pakilinson.

Amathandizira kuteteza masomphenya mwa ana.

Kuperewera kwa dzuwa kumakhala kovuta pa. Asayansi aku Australia adazindikira kuti ana omwe amachititsa kuti azichita nthawi yayitali mchipindamo nthawi zambiri angapewe pang'ono. Chowonadi ndi chakuti dzuwa limapanga kupanga Dopamine yambiri. Nerotiator iyi imathandizira kuti aletse kuchuluka kwa diso, kumabweretsa mapangidwe a Myopia.
