Is sexual orientation associated with sleep difficulties? In this article, we review empirical evidence that addresses this question. Stress is associated with sleep difficulties such as insomnia and, because members of sexual minorities experience greater stress, on average, than do others, lesbian, gay, and bisexual (LGB) individuals can be expected to report more sleep difficulties than their heterosexual peers. We reviewed 17 studies published since 1990, with data gathered from more than 600,000 individuals; some included data on both quantity and quality of sleep. In nine of 12 relevant studies, at least some sexual minority individuals reported shorter sleep duration than did heterosexual individuals, on average. In nine of 10 relevant studies, sexual minority individuals reported lower quality sleep, on average. Few data were available about other aspects of sleep as a function of sexual orientation. No investigators found LGB people to have fewer sleep difficulties than did heterosexual individuals. We conclude that, although research in this area is new and still limited in some respects, sleep difficulties are more common among LGB than heterosexual people. Our conclusion suggests the possibility that sleep difficulties may underlie known health disparities among members of sexual minorities. Further research is needed to evaluate differences in sleep difficulties among members of sexual minorities, and to explore treatment options for LGB individuals suffering from sleep difficulties.
