Brief Sickness after Sunbed?

Recently used a sun bed (Well, sun booth, it was one where you stood up)... I was only in for 3 minutes... as it was my first time using a sun bed, and im not planning on using it as a regular thing, just to take the edge of the white glow for summer low, so that i have a slight 'slow'. After i got out and got dressed,about 5 minutes later i felt really really sick, however, within a minute or two it passed? What are the chances of this being related to the sun bed or being related to something else? (At the moment im experimenting with some food intolerances i might have, so could be linked to that?) Or is it likely to be not drinking enough before i used it, eating to soon before i used it, or that my body just doesnt like it? Oh, Im not looking for lectures that its bad for you and im gonna die of cancer, i know that prolonged exposure, just as to the normal sun can ber very bad for you, but as i mentioned its not like 20 minutes on a regular basis every week of the year... its just a little bit here and there to build up a glow for summer :)
