Higher temperatures associated with an increase in suicide rate



Suicide rates tend to rise in the months with above-average temperatures, according to a study published on Monday that provides a new understanding of the possible link between climate change and mental health.

Article published in the journal Nature Climate Change analyzed data from thousands of American and Mexican neighborhoods over several decades and found that US suicide rates rose by about 0.7%, when temperatures rose 1 ° C in one month, 2.1% in Mexico.

Researchers' analysis of the "depressive language" over 600 million social media updates indicates that general mental well-being is deteriorating even in times of above-average temperatures.

The researchers, who controlled for other factors while examining the relationship between monthly temperatures and suicide rates, concluded that "suicide rates in both a developed and a middle-income country are robust with local temperatures keep in touch."

The authors of the study predict that "unexplained climate change" in the next three decades could result in between 9,000 and 40,000 more suicides in the US and Mexico, "a change in suicide rates comparable to the estimated impact of economic recessions, Suicide Prevention Programs or Weapon Restriction Acts. "

Recent studies have found that the global temperature of the earth will rise more than 2 degrees Celsius later in the century.

"The vast scope of our findings provides further impetus to better understand why temperature affects suicide and introduces measures to mitigate future temperature rise," the study says

Relativity does not mean causation, and many different factors contribute to suicide risk.

Several studies have demonstrated links between climate change and mental health, whether directly or indirectly. The authors of the study pointed to research from India, which showed a connection between teratogenic temperatures and suicide rates.

The authors of this study focused on suicide because they are one of the leading causes of death worldwide, especially in wealthier countries. Suicide, according to the Centers for Disease Control and Prevention, is the tenth leading cause of death in the US, and the suicide rate increased by more than 25% between 1

999 and 2016.
