Abantu benshi bibwira ko kuryama ku zuba nta kirinda izuba bitera akaga kurusha gukoresha agatanda ko kwisiga. Mu by'ukuri,Uburiri bwo gusiga ibara ry'umuhondo bushobora kwangiza—cyangwa bukanaba bubi—kurusha kwihisha ku zuba ritarinzwe, bitewe n'ubukana, igihe, n'inshuro.
Imirasire ya UV: Ikibazo cy'ingenzi
Uburiri bwo gusiga ibara ry'izuba n'izuba ry'izuba byombi bishyira uruhu rwawe kuimirasire ya ultraviolet (UV), byangiza uturemangingo tw'uruhu na ADN.
-
Umucyo w'izuba:Itanga uruvange rwa UVA na UVB
-
Uburiri bwo gusiga ibara ry'uruhu:GusohoraUVA yiganjemo cyane, akenshi ku bushyuhe bwinshi cyane
UVA yinjira cyane mu ruhu kandi ikagira uruhare runini muri ibi bikurikira:
-
Gusaza imburagihe
-
Iminkanyari
-
Gutakaza ubushobozi bwo gukomera kw'uruhu
-
Ingaruka z'igihe kirekire ku ndwara ya kanseri
Impamvu uburiri bwo gukaraba bushobora kuba bubi kurushaho
Ugereranyije n'izuba risanzwe ridafite izuba ririnda izuba, akenshi gushariza ahantu hameze nk'izuba:
-
Tangadose zikomeye za UVA mu gihe gito
-
Kutagira ibimenyetso karemano by'uburinzi (ubushyuhe, kumererwa nabi)
-
Shishikariza abantu gukora imyitozo yo kwiyerekana kenshi
-
Hindura igitekerezo cy'uburiganya ku kugenzura no kurinda umutekano
Gukoresha irangi rimwe gusa bishobora gutuma uruhu rushoboraUVA nyinshi nk'amasaha menshi y'izuba rya saa sita.
Kugereranya ibyago bya kanseri y'uruhu
Ubushakashatsi buhora bugaragaza:
-
Gukoresha uruhu kenshi mu buriri byongera cyane ibyago byo kwandura melanoma
-
Kwishyiramo cyane UVA byihutisha kwangirika k'uruhu
-
Ingaruka ziyongera cyane iyo gushushanya uruhu bitangiye kugaragara bakiri bato
Kwihisha ku zuba utirinze ni akaga—arikoGuhura n'imiraba y'urumuri rw'izuba mu buryo bw'ubukorano bishyirwa mu cyiciro cy'ibitera kanserin'inzego zikomeye z'ubuzima.
Umurongo w'ingenzi
Yego,ahantu ho gusiga ibara ry'izuba hashobora kuba habi kurusha izuba ridafite amavuta akingira izubacyane cyane iyo bikoreshejwe kenshi cyangwa nabi. Byombi ni bibi nta burinzi, ariko uburiri bwo gusiga ibara ry'uruhu butangaimirasire ya UV ikomeye cyane, yiganjemomu gihe gito.
Ibibazo Bikunze Kubazwa
Ese gukaraba mu nzu ni byiza kuruta izuba ryo hanze?
Oya. Gushyira uruhu mu nzu si byiza kandi bishobora kongera ibyago byo kurwara kanseri.
Ese amavuta yo kwisiga atuma uburiri bwo gusiga ibara ry'izuba butagira ingaruka ku buzima?
Indabyo zirinda izuba zigabanya ubushyuhe ariko ntizikuraho kwangirika kwa UV.
