Iko kukakavara kwakapoteredza kunaka uye kwakashata kwemararamiro eUV pahutano hwevanhu kunoenderera mberi, zvisinei, vanhu vakawanda vanotya kenza yeganda uye kuchembera kwekutanga kunokonzerwa nezuva. Zvisinei, nyeredzi inopa chiedza uye upenyu kuzvinhu zvose zvipenyu inoita basa rinokosha mukuchengetedza hutano, kwete chete nekuda kwevhitamini D. UC San Diego vatsvakurudzi vakadzidza zviyero zvesatellite zvechiedza chezuva uye makore munguva yechando kuti vafungidzire serum vitamin D mazinga muna 177. nyika. Kuunganidzwa kwedata kwakaratidza kushamwaridzana pakati peyakaderera vhitamini mazinga uye njodzi ye colorectal uye kenza yemazamu. Maererano nevatsvakurudzi, "Kuwanda kwekuratidzwa kwezuva kwaunowana mukati mezuva kwakakosha pakuchengetedza hutano hwe circadian rhythm. Mitinhimira iyi inosanganisira kuchinja kwemuviri, pfungwa uye hunhu kunoitika kwemaawa makumi maviri nemana uye kunopindura chiedza nerima,” inodaro National Institute of General Medical Sciences (NIGMS). Kurara-kumuka kutenderera kunoenderana zvakanyanya nedoro yemangwanani yechiedza chezuva. Kujeka kwemasikati kunobvumira wachi yemukati yebhayoloji kuti ienderane nechikamu chinoshanda chezuva. Ndicho chikonzero nei zvakakosha kuva muzuva mangwanani, kana kuti rega miranzi yezuva ipinde mumba mako. Izvo zvishoma chiedza chepanyama chatinowana mangwanani, zvakanyanya kuoma kuti muviri urare panguva yakakodzera. Sezvaunoziva, kuratidzwa kwezuva nguva dzose kunowedzera mazinga e serotonin, izvo zvinoita kuti munhu ave akasvinura uye achishanda. Kuwirirana kwakanaka pakati pemazinga e serotonin nechiedza chezuva kwawanikwa mune vanozvipira. Mumuenzaniso wevarume vane hutano hwe24, vatsvakurudzi vakawana kuti kuvapo kwe serotonin muuropi kwakaderera kusvika kudiki mukati memwedzi yechando, asi iyo yepamusoro yepamusoro yakaonekwa apo vatori vechikamu vakanga vari pasi pezuva kwenguva refu. Seasonal affective disorder, iyo inoratidzirwa nekuora mwoyo uye kuchinja kwemafungiro, inobatanidzwawo nekushayikwa kwechiedza chezuva. Dr. Timo Partonen kubva kuYunivhesiti yeHelsinki, pamwe chete neboka revatsvakurudzi, vakawana kuti mazinga eropa echolecalciferol, anozivikanwawo sevhitamini D101, akaderera munguva yechando. Kuratidzwa kwezuva munguva yezhizha kunogona kupa muviri nevhitamini iyi kuti igare munguva yechando, iyo inokurudzira kugadzirwa kwevhitamini D, iyo inowedzera serotonin mazinga. Ganda, kana raiswa mumwaranzi yeultraviolet, rinoburitsa musanganiswa unonzi nitric oxide, unoderedza BP. Muchidzidzo chechangobva kuitika kubva kuYunivhesiti yeEdinburgh, nyanzvi dzedermatologists dzakaongorora kukwira kweropa kwevazvipiri makumi matatu nevana vakaratidzwa mwenje weUV. Munguva yeimwe chikamu, ivo vakaratidzirwa kuchiedza nemirairo yeUV, pane imwe, iyo UV ray yakavharwa, ichisiya chete chiedza uye kupisa paganda. Mhedzisiro yacho yakaratidza kudzikiswa kwakanyanya kweropa mushure mekurapa kweUV, izvo zvisingagoni kutaurwa kune mamwe masesheni.
Mufananidzo wacho unoratidza vanhu vane tuberculosis muNorthern Europe, chirwere chinowanzokonzerwa nekushaya vhitamini D. Varwere vari kupisa zuva.
