An Austrian mental health clinic is drawing attention Wednesday to the fact that global warming directly affects mental health.

“Current data shows a direct link between suicidal tendencies and rising temperatures. A rise of just one degree correlates with a significant increase in suicidal behavior,” the Austrian Society for Psychiatry, Psychotherapy and Psychosomatics (OGPP) said in a statement.

The OGPP sees a connection between heatwaves that have occurred more frequently in recent years and mental health.

Data collected shows that there is an increase in visits to psychiatric facilities or inpatient admissions during periods of heat, it said.
