A study in blind conditions was conducted on 13 women (mean age < 30 years). Six women worked at least four hours per day, five days a week, since more than one month, in front of a video screen constituted the exposed group. Radioimmunoassay of 6-sulfatoxymelatonin was done on urine collected during night. Results were analysed by a non parametric rank-test (Mann-Withney). It was observed an important (- 54%) and significant lower level (p < 0.01) of 6-sulfatoxymelatonin in urine of women exposed to video screen.
