Ubuvuzi bw'urumuri bwabayeho kuva ibimera n'inyamaswa bikiri ku isi, kuko twese twungukirwa ku rugero runaka n'izuba risanzwe.
Umucyo wa UVB uturuka ku zuba ntuhuza gusa na cholesterol mu ruhu kugira ngo bifashe mu gukora Vitamine D3 (bityo bikagira akamaro ku mubiri wose), ahubwo igice gitukura cy'urumuri rugaragara (600 - 1000nm) kinakorana na enzyme y'ingenzi mu mitochondria y'uturemangingo twacu, bikazamura ubushobozi bwacu bwo gutanga ingufu.
Ubuvuzi bw'urumuri bwa none bwabayeho kuva mu mpera z'imyaka ya 1800, nyuma gato y'uko amashanyarazi n'amatara yo mu rugo bitangiye gukoreshwa, ubwo Niels Ryberg Finsen wavukiye mu birwa bya Faroe yageragezaga gukoresha urumuri nk'umuti w'indwara.
Nyuma Finsen yaje kwegukana igihembo cya Nobel mu buvuzi mu 1903, umwaka umwe mbere y'urupfu rwe, agira icyo ageraho cyane mu kuvura indwara z'ibicurane, urusenda n'izindi ndwara z'uruhu akoresheje urumuri rwinshi.
Ubuvuzi bw'urumuri bwa mbere bwakoreshejwe cyane cyane mu gukoresha amatara gakondo, kandi ubushakashatsi bugera ku 10.000 bwakozwe ku rumuri mu kinyejana cya 20. Ubushakashatsi butandukanye bugira ingaruka ku nzoka, cyangwa inyoni, abagore batwite, amafarashi n'udukoko, bagiteri, ibimera n'ibindi byinshi. Iterambere riheruka ryabaye ikoreshwa ry'ibikoresho bya LED na laser.
Uko amabara menshi yagendaga aboneka uko amatara ya LED yagendaga ahinduka, kandi ikoranabuhanga rigatangira kunozwa, amatara ya LED yabaye amahitamo meza kandi afite akamaro mu kuvura urumuri, kandi ni yo asanzwe mu nganda muri iki gihe, aho imikorere yayo ikomeje kwiyongera.
