Abstract
To consider the relationship between suicide prevention and sleep, it is necessary to understand the suicide risk progression. Various facilitating and protective factors are involved in the process of severe stress leading to depression and then to suicidal ideation. Knowledge of risk factors in addition to facilitators can help narrow the target population for suicide prevention. Among the general population, the prevalence rate of suicidal ideation in the last year is as high as 11% among those who do not get enough rest from sleep, and focusing on this population would cover 32% of those with suicidal ideation. However, sleep insufficiency is not a precipitating factor in the development of severe stress into suicidal ideation, but is more likely to form part of a depressive state that falls somewhere between stress and suicidal ideation. If suicide prevention gatekeepers can approach persons with sleep insufficiency, knowing that sleep insufficiency has many causes, and connect them to effective support, they will be effective for both suicide prevention and sleep health.
