The Need for Collective Awareness of Attempted Suicide Rates in a Warming Climate

Area of Science:

• Environmental Psychology
• Public Health
• Climatology

Background:

• Climate factors, such as temperature, may explain variations in suicide rates more effectively than economic variables.
• Previous research suggests a potential link between environmental conditions and mental health outcomes, including suicide attempts.

Purpose of the Study:

• To investigate the specific role of ambient temperature as a determinant of increased prevalence of suicide attempts (SA).
• To analyze the relationship between meteorological data and hospitalization rates for SA.

Main Methods:

• Retrospective analysis of hospitalization data for SA at a psychiatric clinic from August 2013 to July 2018.
• Correlation of SA hospitalization data with ambient temperature data obtained from a university meteorological observatory.
• Statistical analysis to identify patterns and correlations between temperature fluctuations and SA prevalence.

Main Results:

• A discernible peak in suicide attempts was observed during late spring and early summer.
• This seasonal peak in SA prevalence is potentially linked to rising global warming trends and associated temperature increases.
• The findings suggest a correlation between higher ambient temperatures and an increased incidence of suicide attempts.

Conclusions:

• Climatic factors, specifically temperature, appear to influence suicide behavior.
• Further research is warranted to elucidate the complex impact of climate on mental health and suicide.
• Findings support the need for developing targeted early intervention and preventive mental health strategies considering climatic influences.
