    There appears to have been many studies since 1995 – I have found many which refer to the original study mentioned above.

    Have made a web page which contains the PDF of the study, a table of results from it, and will soon have follow-on studies. http://is.gd/uvb_room

    Thanks for the great link. Also the colors of the room can have a major effect. A good book on this is Light- Medicine of the Future by Liberman.
