Exploding head syndrome, chronotype, parasomnias and mental health in young adults

Exploding head syndrome, chronotype, parasomnias and mental health in young adults:

Abstract

Although inadequate sleep among young people is well documented in the literature, anomalous sleep experiences, such as the parasomnia termed exploding head syndrome (EHS), have received little empirical attention. The current study examined the association of sleep quality, symptoms of psychological distress and other unusual sleep experiences with EHS in a sample of young adults (n = 135, age M = 21.77, SD = 2.08). We also aimed to account for the possible effect of participant chronotype on sleep experiences. The lifetime prevalence of EHS among participants was 20.0%. Three‐quarters (75.6%) of participants reported poor quality sleep according to the Pittsburgh Sleep Quality Index (PSQI). Univariate analysis showed that participants with a lifetime prevalence of EHS experienced more symptoms of anxiety and poorer sleep quality; age, gender and symptoms of depression were not significantly related to EHS. Parasomnias (OR [95% CI] = 1.62 [1.02–2.57], p = .040) and action‐related sleep disorders (OR [95% CI] = 1.87 [1.09–3.20], p = .023) were associated with lifetime experience of EHS in a logistic regression analysis. Chronotype did not significantly impact mood, sleep quality or presence of EHS. Results suggest that EHS is more common in young people than previously considered and ought to be examined in conjunction with the presence of other unusual sleep disorders. This study provides valuable insight into young peoples' sleep experiences and key factors associated with EHS.
