New study shows connections between climate change and suicide risk – health



A new study has shown that climate change can affect a person's mental health.

The study published in the journal Natural Climate Change suggests that at abnormally high temperatures in one month of suicide rates are also likely to be higher, compared with months of normal average temperatures.

Although the study findings do not suggest temperature as the single most important factor associated with suicide, the lead author of the study and assistant professor at Stanford University Department Marshall Burke notes that there is indeed a very consistent relationship between the two.

As reported by CNN, the study included data on suicide rates in the United States between 1

984 and 2004, as well as monthly suicide rates in Mexico between 1990 and 2010. Researchers used a climate mapping tool called PRISM to provide these data with temperature and to compare precipitation data from the USA.

They analyzed the data and found that an increase in the average monthly temperature by 1 degree Celsius correlated with an increase in suicide rates by 0.68 percent in the US and 2.1 percent in Mexico.

The study also shows an increase in expression of depression language through social media platform Twitter.

Burke mentions that these results suggest that humans have a physiological response to hot temperatures.

"Studies suggest that some components of brain chemistry, especially certain neurotransmitters, are important for mental health as well as how the body regulates its internal temperature," he says. "For us, a physiological explanation fits our data better because we have such a remarkably consistent relationship with all socio-economic groups in the US."

Other similar studies show the effects of rising temperature on mental well-being, such as the study of hospital admissions in Milwaukee, which found a relationship between "deliberate self-harm" and warmer temperatures. (anm / kes)
