Solforbrenning: Årsak

Ultraviolette stråler fra sola påvirker huden vår på mange måter. Både UVA-stråler og UVB-stråler gjør at vi blir brune i sola, men det er kun UVB-strålene som gir huden beskyttelse mot solstrålenes negative effekter ved å gjøre huden tykkere og ved å øke produksjonen av pigment. Man tror at det er UVB-strålene som gir solforbrenning, mens UVA-strålene forårsaker soleksemet.

I tillegg til allergier og eksem øker uvettig soling hudens aldringstegn i form av rynker, og faren for hudkreft økes.

Som nevnt skyldes de fototoksiske og fotoallergiske eksemene reaksjoner mellom UV-stråler og stoffer enkelte har i huden. En lang rekke medisiner kan gi slike reaksjoner, blant annet enkelte antibiotika, antidepressiver, antipsykotiske medikamenter, p-piller og mange flere. Det er også viktig å huske på at ting du smører på huden, kan gi slike reaksjoner. Særlig gjelder dette parfymer.
