Ibitanda byo gusiga ibara ry'izuba bikoreshwa cyane kugira ngo bigire ibara ryihuta kandi ringana, ariko umutekano wabyo uracyari ikibazo gikunze kugaragara. Nubwo ibitanda byo gusiga ibara ry'izuba bitanga ubwiyongere bugenzurwa, biracyatanga imirasire ya ultraviolet (UV), ishobora guteza ibibazo ku buzima.
None se, ahantu ho gusiga ibara ry'izuba hari umutekano ungana iki? Igisubizo gito ni ukoUburyo bwo kugabanya ibara ry'imirasire y'urumuri nta mirasire y'izuba bufite umutekano rwose, kandi gusobanukirwa ingaruka mbi ni ngombwa mbere yo gukoresha.
Ni ubuhe bwoko bwa UV bukoreshwa mu gukaraba uruhu?
Uburiri bwinshi bwo gusiga ibara ry'izuba bugezweho butanga:
-
Imirasire ya UVA 95–99%, byinjira cyane mu ruhu
-
Umubare muto waimirasire ya UVB, bitera ubushyuhe bw'izuba kandi bigatera vitamine D
Nubwo UVB nkeya igabanya ubushyuhe bw'ako kanya, kwibasirwa cyane na UVA bigira uruhare mu kwangiza uruhu igihe kirekire.
Ingaruka zishobora guterwa n'ibitanda byo kwisiga ku zuba
Gukoresha utubari two gusiga ibara ry'izuba byongera ibyago byo:
-
Gusaza uruhu imburagihe n'iminkanyari
-
Gutakaza ubushobozi bw'uruhu bitewe no kwangirika kwa kolajeni
-
Ibara ry'uruhu rikabije n'ibizinga by'imyaka
-
Ingaruka zo kurwara kanseri y'uruhu ziyongera, harimo na melanoma
Ubushakashatsi bwerekana ko gukoresha irangi ry’uruhu kenshi—cyane cyane guhera mu bwana—byongera cyane ibyago byo kwandura melanoma.
Ese ahantu ho gushushanya uruhu hari umutekano kurusha kuzuba?
Abantu benshi bibwira ko ibitanda byo gusiga ibara ry'umuhondo ari byiza kuruta kwibasirwa n'izuba kuko amasaha yo gusiga ibara ry'umuhondo aba magufi kandi akagenzurwa. Ariko, ibitanda byo gusiga ibara ry'umuhondo bishobora gutanga umusaruro mwiza.imirasire ya UVA ikomeye kurusha imirasire y'izuba isanzwe mu gihe gito cyane.
Mu by'ukuri, igihe cyo kuryama ku ruhu kimwe gishobora kunganaamasaha yo kwibasirwa n'izuba rya saa sitaku bijyanye n'igipimo cya UVA.
Ni nde ukwiye kwirinda gusiga ibara ry'uruhu ku buriri?
Ntibyemewe ko ibitanda byo gusiga ibara ry'uruhu kuri:
-
Abantu bafite uruhu rwiza cyangwa rufite uruhu rworoshye
-
Abantu bafite amateka ya kanseri y'uruhu
-
Abantu batwite
-
Umuntu wese ufata imiti ishishikariza abantu gufata amashusho
Abana bato kandi babujijwe cyangwa babujijwe gukoresha ibitanda byo gusiga ibara ry'uruhu mu turere twinshi.
Ese uburiri bwo gukaraba bushobora gukoreshwa "mu mutekano"?
Nubwo nta gukaraba UV ku buryo butagira ingaruka, uburyo bwizewe burimo:
-
Kugabanya igihe cy'imyitozo n'inshuro
-
Kwemerera nibura amasaha 48 hagati y'igihe
-
Kwambara uburinzi bw'amaso bukwiye
-
Kwirinda ko habaho izuba ryinshi kuri uwo munsi
Nubwo habayeho ingamba zo kwirinda, kwangirika k'imirasire y'urumuri rw'izuba biracyabaho.
Uburyo bwizewe bwo gukoresha irangi ry'imirasire ya UV
Niba intego yawe ari ukugaragara neza cyangwa ubuzima bwiza budafite ingaruka ku mirasire y'izuba:
-
Ibikoresho byo kwisiga uruhu bidakoresha izubagutanga ibara ridafite imirasire
-
Ubuvuzi bw'urumuri rutukuraishyigikira uruhu rusa neza rudakoresheje ibara ry'uruhu cyangwa ngo rubeho mu mirasire ya UV
Izi nzira zifatwa nk'izifite umutekano ku buzima bw'uruhu igihe kirekire.
Umwanzuro wa nyuma
None se, ahantu ho gusiga ibara ry'izuba hari umutekano ungana iki?
Nubwo bishobora gusa n'aho byoroshye, ibitanda byo gusiga ibara ry'izuba bishyira uruhu ku mirasire ya UV yinshi kandi bigatera ingaruka zikomeye ku buzima.ntibifatwa nk'aho ari umutekanocyane cyane iyo ikoreshejwe buri gihe.
Kugira ngo uruhu rube rwiza, kugabanya kwibasirwa n'imirasire y'izuba no guhitamo ubundi buryo butari ubudakoresha imirasire ya kanseri y'izuba ni bwo buryo bwiza.
Ibibazo Bikunze Kubazwa
Ese uburiri bwo gusiga ibara ry'umuhondo burimo umutekano kurusha izuba?
Oya. Uburiri bwo gushushanya ibara ry'uruhu bukunze gutanga imirasire ya UVA ikomeye kurusha imirasire y'izuba isanzwe.
Ni kangahe byaba ari byiza gukoresha agatanda ko gusiga ibara ry'uruhu?
Nta gihe ntarengwa cyuzuye. Kugabanuka kw'ibiyobyabwenge bigabanya ibyago ariko ntibibikuraho.
Ese uburiri bwo gusiga ibara ry'uruhu butuma umuntu asaza vuba?
Yego. Kugaragara cyane mu mirasire ya UVA byihutisha gusaza k'uruhu no kurema iminkanyari.
