Suicide is a global public health concern: human activities and rapid urbanisation influence the environments in which people live, and this may impact on health, including mental health. In particular, a recent article published on The Lancet Planetary Health by M.Helbich and colleagues, focuses on the association between natural environments and population suicide risk. Authors studied how green or blue spaces may influence suicide rate in association with many socio-economic factors and provide references on previous studies about how suicide-methods access may contribute to suicidal behaviors.
Moreover, “suicide hotspots” should be considered among the environmental factors that may influence suicide rate in a specific context. Several articles have been published about this topic in different countries: on PloS One, in 2017, it was published a Swiss study that compares different suicide prevention measures in jumping hotspots; an Austrian study (2017) focuses on railway suicide, studying clustering phenomena, and particular events occuring in proximity to psychiatric institutions in order to help further prevention strategies.
