The impact of daylight on suicide rates
2022, Economics and Human BiologyCitation Excerpt :Some argue that men are more impulsive than women are, which explains significant results from daylight on male suicides but less so for female suicides (Preti and Miotto, 1998). Several researchers argue that impulsive actions, relating to daylight and serotonin levels, explain why there is a significant correlation between daylight and violent suicides, and a non-significant relationship with non-violent suicides (Linkowski et al., 1992; Maes et al., 1994; Preti and Miotto, 1998; Lin et al., 2008; Reutfors et al., 2009; Vyssoki et al., 2012). Impulsivity may also change throughout one’s life course.

2019, Journal of Psychiatric ResearchCitation Excerpt :Serotonin abnormalities are also strongly linked with impulsive violence (Virkkunen et al., 1996), and multiple studies show that hotter climates and hotter days in a given location are correlated with higher rates of violence (Gamble and Hess, 2012; Sorg and Taylor, 2011). Similarly, several studies have identified violent suicide to be specifically correlated with acute increases in temperature and sunlight (Dixon et al., 2014; Hee-Jung et al., 2017; Linkowski et al., 1992). There are multiple reasons to think that patients with presumed serotonergic disturbances might struggle with acute changes in climate.

2018, Neurology Psychiatry and Brain ResearchCitation Excerpt :Temperature and precipitation are, of course, closely correlated with hours of sunshine, and the independent consequences of each are difficult to disentangle (Bazas et al., 1979; Lambert et al., 2002). As with hours of sunshine, suicide rates have been shown to increase with both colder (Linkowski et al., 1992; Souetre et al., 1987; Souêtre et al., 1990; Tsai, 2010) and hotter (Dixon et al., 2014; Dixon and Kalkstein, 2018; Kim et al., 2011; Lee et al., 2006; Likhvar et al., 2011; Page et al., 2007) temperatures, and to be uncorrelated (Dixon et al., 2007). Higher rainfall has been shown to be associated with increased numbers of suicide attempts (Barker et al., 1994), but not with suicide rates (Ajdacic-Gross et al., 2007).
