Zuva uye zvasikwa dzimwe nzira

Iyo radiation yeUV ndiyo inoshanda kune vhitamini D synthesis iri muganda, nekuwedzera, zuva rakasimudza mamiriro edu. Asi nechekare mumakore e1930er imwe yaive ichizivawo nezvengozi dzekuwandisa kwemagetsi epasi. 1933 yakatotumira patent yeDrugofa GmbH, inotsigira Bayer, kune chigadzirwa chinonzi Delal. Iyo yekutanga sunscreen ine UV yekudzivirira firita, yekutanga sunscreen, yakazvarwa. Hombodo, masipuni kana maoiri akasaswa pamisoro yezuva panguva ye1980 makore akanyatsowanikwa mukukosha. Nenguva isipi munhu wese akataura nezve gomba re ozone uye zuva rekuchengetedza chinhu pane zvakasiyana zvigadzirwa rakasimuka nekukurumidza.

Zvigadzirwa zvine UVA chisimbiso inoona kuti iyo UVA dziviriro chinhu chinenge chikamu chimwe muzvitatu che UVB yekudzivirira chinhu. Iyo yezuva yekudzivirira factor inoreva iyo chete yekudzivirirwa kubva kumaruva e UVB, UVA radiation inowanzo kubhadharwa zvishoma. Chisimbiso cheUVA chinyorwa chakanaka paunosarudza iyo sunscreen chaiyo.

Izvo zvisingaonekwe: UV radiation

Pamusoro pekuvhenekera kwaro kunoonekwa, mwenje wezuva une marefu-wave eUWA radiation, pfupi-wave UVB radiation uye UVC radiation, isingasvike pasi nekuda kweiyo ozone layer. Radiation yeUV inoshanda nekuita kuti ganda rive brown. Maitiro aya maitiro ekudzivirira. Iyo epidermis ine pigment-inoumba masero, melanocyte, ayo brown pigment melanin anochengetedza ganda kubva kumagetsi ezuva. Kana yakanyanya UVB radiation ichirova isina kudzivirirwa ganda, pane mhinduro yekupokana inoenderana nekupisa, kupisa kwezuva. Asi kunyangwe marefu mawere eUVA haagone kukuvadza. Ivo vanopinda zvakadzika mukati meganda uye vanokuvadza collagen yeganda, iyo inotungamira kuderera kweganda elasticity uye nekudaro kune yekukasira kukwegura uye makomba.

UV ngano pamusoro pezuva

Kuwedzerwa kwenguva refu kwesikweya inowedzera nguva yekuchengetedza?
Kwete, kuchengetedzwa hakuwedzerwe, asi kunochengetwa. Semuenzaniso, chero munhu anowana ganda dzvuku muzuva asina kudzivirirwa mushure memaminitsi gumi anokwanisa kugara muzuva kweanenge maawa mashanu aine chidziviriro chezuva XXUMX.

Ko ma Blondes anoda akakwirira ekudzivirira kwezuva chinhu pane kusviba bvudzi?
Kwete, nekuti haisi iro bvudzi bvudzi rinokosha, asi rudzi rweganda.

Kana ganda rave kurukwa, hauchabatwe nezuva zvakare?
Kupopota kuchiri kukosha. Ganda harifi rakajaira zuva zvachose uye risingakanganwe kukuvara kwezuva.

Iyo solarium inobatsira kudzivirira kupisa kwezuva? Kwete, zuva rakashanda rinoshanda neUVA mwenje. Kubva pane maonero ekurapa, kuwedzerwa kweganda kuchiedza cheUV kunofanira kudzivirirwa. Izvi zvinotungamira kune kusakara kweganda. Panguva imwecheteyo, iyo njodzi yekukuvara kenza yeganda inokurudzirwa.

Sunscreen & Mushure mezuva

Mafuta mazhinji ezuva anovimba nekubatanidzwa kwemafilita epanyama uye emakemikari. Titanium oxide kana zinc oxide yemuviri mafirita inoratidzira uye inoparadzira inopinda UV yechiedza senge magirazi madiki. Mafirita emakemikari anoshandura marara eUV akaipa kuva simba risingakuvadzi, kureva kukuvadza infrared chiedza kana kupisa. Mune Mushure mezvigadzirwa zveSun, ganda rinofefetesa vamiririri senge algae vera rinoshandiswa kutonhodza uye kudzora ganda mushure mekupiswa nezuva. Mushure me20-miniti UV kudiridza, kukuvadza kune genetic zvinhu zveganda maseru kunoitika. Zvimwe zvinotevera-zuva zvigadzirwa saka zvine enzyme Photolyase, iyo inotsigira iro ganda remuchina kugadzirisa. Kwenguva yakati rebei iko zvino maitiro ave ekuenda kune anonzi-kuyambuka-zvigadzirwa. Semuenzaniso, vanopisa kwemazuva kana vanozvisarudzira ikozvino vava neUVA uye UVB mafirita.

Mineral sunscreen (inonzi zvakare sunscreen yenyama) inzira yakasarudzika kune echinyakare zvimiro zvezuva uye zvinosipika uye zvakare ichipa zvinodzivirira zvinobudirira kubva kumwaranzi yeUV. Kusiyana nemakemikari sunscreens, zvigadzirwa zvemaminerari zvinoshanda pane imwe musimboti: zvicherwa zvakasikwa zviripo paganda uye zvinoratidza iyo inouya UV mwenje segirazi yechiedza. Aya maficha ezuva ezuva anoshanda nekukurumidza mushure mekushandisa uye asiri mahormoni-anoshanda. Iyo yakasikwa mineral pigment pigment mune emulsion zvakare inoonekwa: Kuburikidza neyakajeka kuratidzika ivo vanoratidzika seyakachena shimmer, ganda rinoonekwa rino chena uye rinotyisa. Kujaira.

Mukukurukurirana naDr. Dagmar Millesi, nyanzvi mupurasitiki nekuvhiya kwekushongedza kwezuva kirimu, kupisa kwezuva & Co.

Sabata: Chii chinoitika kune ganda?
Millesi: "Zuva rinobuda marasha eUV. Izvi zvinotungamira kuburitswa kwevamwe vatumwa vakaita se histamine kana interleukins muganda. Yakawandisa radiation inokonzeresa kudzikira kwemidziyo yeropa, kutsvuka uye kuzvimba kwenzvimbo yeganda rakakanganisika. Kubaya kana kupisa ndiwo mugumo. Uku kuzvimba kunoita ganda rinodaidzwa kuti sunburn. Pakupisa kwezuva, zvinokonzerawo kuputika uye kazhinji fivha, kusvotwa, kutonhora uye kurutsa. "Kuvira kwezuva kupisa kweganda uye kunofanirwa kudzivirirwa zvachose."

Rinoshanda sei zuva?

Iyo makemikari UV mafirita anopinda mukati meganda mushure mekushandisa uye anoumba mhando yemukati yekudzivirira firimu. Izvi zvinoshandura UV rays kuva infrared mwenje uye nokudaro mukupisa. Chinhu chakashata ndechekuti aya mazuva anochera chete mushure meinenge 30 maminetsi chiito, mukuwedzera, vamwe vanhu vanozvitora zvinopesana nazvo. Mafetera enyama haapinde mukati meganda asi anouita firimu rinodzivirira kunze kweganda. Nekuda kweizvozvo, UV mawarosi akavharirwa kana kuratidzwa. "Kubatsira kwezviitiko izvi kwezuva ndezvekuti vanoshivirirwa zvakanaka."

Kune zvekare here sunscreen?
Millesi: "Yakanakisa sununguko yezuva ndeyekudzivirira kuratidzwa kwakasimba kwezuva. Saka usazvifananidze nechero masikati machena masikati, tsvaga nzvimbo dzine shady uye pfeka zvipfeko uye musoro une zuva. Zvakare, mamwe mafuta anogona kuita seyakareruka zuva, senge sesame oiri, kokonati mafuta kana jojoba mafuta. Izvi nhoo chete 10-30 muzana yeUV rays. Asi mumwe haafanire kukanganwa kuti mwenje yezuva inozadzisa akakosha mabasa mumuviri wemunhu. "Inobatsira kugadzirwa kwevhitamini D, ine chirevo chakakosha pazvinhu zvevatumwa, senge serotonin, uye inogona zvakare kukanganisa mahormone."
