Sleep disturbances like insomnia and nightmares are significant risk factors for suicidal ideation and behaviors (SIB). Targeting these sleep issues may offer new avenues for suicide prevention strategies.

Area of Science:

  • Psychiatry
  • Sleep Medicine
  • Public Health

Background:

  • Sleep disturbances, including insomnia, nightmares, and excessive daytime sleepiness (EDS), are prevalent and modifiable. They represent significant risk factors for suicidal ideation and behaviors (SIB).
  • Understanding the link between sleep and suicidality is crucial for developing effective prevention strategies.

Purpose of the Study:

  • To review the evidence linking insomnia, nightmares, and EDS to SIB.
  • To discuss the prevalence of these sleep disturbances in the general population and their association with psychiatric disorders.
  • To explore potential mechanisms and confounders in the relationship between sleep disturbances and SIB.

Main Methods:

  • A comprehensive literature search was conducted using PubMed to identify relevant studies.

  • The review synthesized existing evidence on the association between specific sleep disturbances and SIB.
  • Analysis included epidemiological data and clinical observations.

    • Main Results:

    • Insomnia is highly prevalent in mental disorders and particularly associated with SIB; insomnia interventions show promise for reducing suicidal ideation.
    • Nightmares appear to be an independent risk factor for SIB, especially in young individuals and with frequent occurrence.
    • The link between EDS and SIB is less clear, potentially mediated by reduced quality of life and comorbid depression.

    Conclusions:

    • Sleep disturbances, particularly insomnia and nightmares, are critical targets for suicide prevention.
    • Further research is needed to clarify the role of EDS and explore underlying mechanisms and confounders.
    • Interventions addressing sleep problems could significantly impact SIB reduction efforts.
