Relationship of insomnia to sexual function and sexual satisfaction: Findings from the sleep and sex survey II.

ABSTRACT

OBJECTIVE: Research suggests that healthy sleep is a key component of sexual function. When evaluating sexual function, however, poor sleep is often overlooked as a contributing factor. This cross-sectional survey expands prior work by exploring relationships among insomnia severity, sexual satisfaction, and sexual function with an updated battery of measures for the Sleep and Sex Survey. METHOD: The sample (N = 1266) consisted of 618 men, 648 women recruited via Prolific, an online survey platform. The Sleep and Sex Survey II included measures addressing insomnia, fear of sleep, nightmares, sexual function, sexual satisfaction, sexual activity, depression, anxiety, posttraumatic stress, and alcohol use. RESULTS: Recent sexual activity was correlated with better sleep, lower anxiety, and lower scores on a posttraumatic stress disorder screener. Insomnia severity was negatively correlated with sexual satisfaction (r = 0.22, p < .001) and the presence of insomnia was associated with higher rates of sexual dysfunction in women (53.8% vs. 31.8%; p < .001) and men (22.7% vs. 12.5%; p = .036). In regression analyses, after accounting for depression and anxiety, insomnia had a statistically significant association with sexual function for women (ß = 0.12; p < .01) but not men (ß = 0.11; p = .60). CONCLUSION: Findings support a relationship of insomnia to sexual function and satisfaction with some gender differences. Future work may be enhanced by assessing these relationships in a gender diverse population including objective sleep measures and addressing contributing mechanisms. Clinically, findings support the assessment of sleep when evaluating patients for sexual dysfunction.
