Ukwelashwa nge-UVukwelashwa kokukhanya kwe-ultraviolet okungu-311 ~ 313nm. Kwaziwa nangokuthi ukwelashwa ngemisebe ye-ultraviolet engu-narrow spectrum (Ukwelashwa kwe-NB UVB).Ingxenye encane ye-UVB: ubude be-wavelength obungu-311 ~ 313nm bungafinyelela ungqimba lwe-epidermal lwesikhumba noma indawo yokuhlangana kwe-epidermis yangempela, futhi ukujula kokungena akujulile, kodwa kusebenza kumaseli aqondiwe njenge-melanocytes, futhi kunomphumela wokwelapha.
Izivivinyo zemitholampilo zikhombisile ukuthi ububanzi bobude be-311-312 nm obukhishwa yi-311 narrow spectrum UVB bubhekwa njengokukhanya okuphephile nokusebenza kahle kakhulu. Bunezinzuzo zokusebenza kahle kanye nemiphumela emibi emincane ye-psoriasis, i-vitiligo nezinye izifo zesikhumba ezingamahlalakhona.
Kodwa-ke, kungcono ukulandela iseluleko noma imiyalelo kadokotela uma usebenzisa ithuluzi le-ultraviolet phototherapy, ngoba ukusetshenziswa ngokweqile kwethuluzi le-ultraviolet phototherapy kuzovela ukusha okuncane, okubonakala njengesikhumba esibomvu, ukusha, ukuxebuka kanye nezinye izimpawu zokusha okuncane.
Okwesibili, imisebe ye-ultraviolet izolimaza ne-retina nge-cornea, okuholela ekulimaleni kwamangqamuzana e-retina, ngakho-ke abantu noma izilwane ezivezwe emisebeni ye-ultraviolet isikhathi eside kwakungcono zigqoke izingubo zokuzivikela kanye neminye imishini, zigqoke izibuko zelanga zokuzivikela.
