Study Objectives

War profoundly impacts various aspects of human life. The effects of war on sleep have been mainly studied among military personnel who are directly exposed to combat. The present work studies changes in sleep patterns of the civilian population following a war, assessing sleep before and during the 2023-2024 Israel{\textendash}Hamas war.

Methods

Study 1 compared the national prevalence of insomnia before and during the war by analyzing data from the 2023 Israeli Central Bureau of Statistics survey (N\ = 6,474). Studies 2 and 3 comprehensively assessed reports on sleep before the war and 2-3 months into the war through validated tools, and also measured psychological distress and demographics. These studies included two independent samples (N\ = 1,706), one of which was representative of the Israeli population. Study 4 re-surveyed the representative sample of Study 3 six months into the war (N\ = 273).

Results

In Study 1, the incidence of insomnia symptoms rose markedly during the war. In Studies 2 and 3, participants reported a 19-22 \% increase in the prevalence of short sleep (\< 6 hours/night), a 16-19 \% increase in clinical insomnia, and a 4-5 \% increase in sleep medication usage compared to before the war. In Study 4, 6 months into the war, the majority of sleep impairments persisted despite reduced psychological distress. Across studies, women and individuals with greater exposure to trauma were more strongly affected.

Conclusions

The findings of four studies demonstrate the detrimental effects of warfare on civilians{\textquoteright} sleep, indicating that these effects are likely long-lasting. The findings identify precursors for sleep problems and underscore the relationships between sleep, trauma, and psychological distress.
