Heat and suicidal attempts

In a project led by Shaked Yarza we investigated the association between suicidal behavior and temperature (Yarza et al, 2020). Our group demonstrated that suicide attempts become more likely when temperature is anomalously high compared to typical values, especially during the summer. We also noticed that people with a history of a suicidal attempt are most sensitive to temperature increase, regardless of a season. Likewise, we found that over 2 days of increase in temperature, is associated with an increased risk for suicide attempts in the following days.
