[Sleep of sleep research personnel--results of the Munster Congress survey].

Due to different knowledge of sleep and sleep disorders (i.e. focussing) sleep quality of sleep-researchers may be better or worse than the sleep of other scientists. On the Münster Congress for Sleep-research and Sleep medicine in March 1994 we investigated this question using the Pittsburger Sleep Quality Index (PSQI). 46 sleep researchers, 52 practitioners and 103 scientists of other disciplines from the Münster University filled out the questionnaire. Results show no difference in overall sleep quality between the three groups, but only sleep quality in the group of sleep researchers shows a bimodal distribution suggesting a subpopulation with more serious sleep problems. 10 to 15% of the total academic population can be regarded as "poor" sleepers. Especially the group of practitioners, in which we found the highest values of daytime sleepiness, seems to be a risk-population for sleep disorders.
