Gukoresha uburyo bwo kuvura urumuri nk'ibitanda bitukura mu gufasha gukira byakoreshejwe mu buryo butandukanye kuva mu mpera z'imyaka ya 1800. Mu 1896, umuganga wo muri Danemark witwa Niels Rhyberg Finsen yateguye uburyo bwa mbere bwo kuvura urumuri ku bwoko runaka bw'igituntu cy'uruhu ndetse n'indwara y'ibicurane.
Hanyuma, uburyo bwo kuvura urumuri rutukura (RLT) bwakoreshejwe mu myaka ya 1990 kugira ngo bufashe abahanga mu bya siyansi guhinga ibimera mu isanzure. Abashakashatsi basanze urumuri rwinshi rutangwa na diode zitukura (LED) rwafashije mu gukura kw'ibimera ndetse no gukora fotosinthesisiyo. Nyuma y'ubu buvumbuzi, urumuri rutukura rwakoreweho ubushakashatsi ku buryo rushobora gukoreshwa mu buvuzi, cyane cyane kugira ngo harebwe niba uburyo bwo kuvura urumuri rutukura bushobora kongera ingufu mu turemangingo tw'abantu. Abahanga mu bya siyansi bizeye ko urumuri rutukura rushobora kuba uburyo bwiza bwo kuvura indwara yo kugabanuka kw'imitsi - kwangirika kw'imitsi bitewe no kutagira aho ijya haba bitewe n'imvune cyangwa kutagira imyitozo ngororamubiri - ndetse no kugabanya gukira kw'ibikomere no gufasha mu bibazo by'ubucucike bw'amagufwa biterwa no kutagira ibiro mu gihe cyo kugenda mu kirere.
Abashakashatsi bamaze kubona ko nyinshi zikoreshwa mu kuvura urumuri rutukura. Bivugwa ko ibibyimba byo kuruhuka n'iminkanyari bigabanuka bitewe n'amatara atukura aboneka muri salon zo kwisiga. Ubuvuzi bw'urumuri rutukura bukoreshwa mu biro by'ubuvuzi bushobora gukoreshwa mu kuvura psoriasis, ibikomere bikira buhoro buhoro, ndetse na zimwe mu ngaruka mbi ziterwa na chemotherapy.
Igitanda cyo kuvura urumuri rutukura gikora iki?
Ubuvuzi bw'urumuri rutukura ni uburyo karemano bwo kuvura bukoresha urumuri rurerure rwa infrarouge. Ubu buryo bufite ibyiza byinshi, birimo kugabanya stress, kongera imbaraga, no kongera ubushobozi bwo kwibanda, ndetse no gusinzira neza nijoro. Ubuvuzi bw'urumuri rutukura busa n'ubuvuzi bwo gusiga ibara ry'umutuku iyo bigeze ku isura, nubwo ubuvuzi bw'urumuri rutukura budafite imirasire mibi ya ultraviolet (UV).
Ese uburyo bwo kuvura urumuri rutukura butekanye?
Nta gihamya kigaragaza ko gukoresha ubuvuzi bw'urumuri rutukura ari bibi, nibura iyo bukoreshejwe igihe gito kandi bukurikije amabwiriza. Ntabwo ari uburozi, ntibutera indwara, kandi ntabwo bubabaza ugereranyije n'ubundi buryo bumwe na bumwe bwo kuvura uruhu. Nubwo urumuri rwa UV ruturuka ku zuba cyangwa ahantu ho gusiga ibara ry'uruhu ari byo bitera kanseri, ubwo bwoko bw'urumuri ntibukoreshwa mu kuvura RLT. Nta ngaruka mbi kandi. Mu gihe ibicuruzwa bikoreshejwe nabi, urugero, bikoreshwa kenshi cyangwa bidakoreshejwe hakurikijwe amabwiriza, uruhu rwawe cyangwa amaso yawe bishobora kwangirika. Niyo mpamvu ari ngombwa kuvura ubuvuzi bw'urumuri rutukura mu kigo cyujuje ibisabwa kandi gifite uruhushya hamwe n'abaganga babihuguriwe.
Ni kangahe wagakwiye gukoresha uburiri bukoresha urumuri rutukura?
