Intense Heat Could Heighten Schizophrenia and Depression Risks: Research

Synopsis

A recent study from the University of Adelaide indicates that rising temperatures may significantly increase the prevalence of mental and behavioral disorders (MBD) like schizophrenia and depression, particularly affecting young adults. The research calls for immediate action to address these mental health challenges as climate change continues to escalate.

Key Takeaways

Rising temperatures could increase MBD rates by 50% by 2050.
Young individuals aged 15-44 are most affected.
Climate change impacts mental health globally.
Policymakers need to focus on public health interventions.
Immediate action is critical to support vulnerable groups.

New Delhi, April 15 (NationPress) Increasing temperatures may not only impact physical health but could also elevate the prevalence of mental and behavioural disorders (MBD) such as schizophrenia and depression by nearly 50 percent by 2050, as indicated by a recent study.

The research, spearheaded by the University of Adelaide, emphasizes the urgent necessity to act promptly to safeguard mental health as the climate continues to warm.

Published in the journal Nature Climate Change, the study reveals that elevated temperatures have resulted in an annual loss of 8,458 disability-adjusted life years (DALYs), which accounts for 1.8 percent of the overall MBD burden in Australia.

Young individuals aged 15 to 44 are particularly vulnerable, with most losses attributed to experiencing poor mental health.

"The adverse effects of climate change on mental well-being and emotional health have been increasingly acknowledged globally, and the situation will only worsen unless we take action," stated lead author Professor Peng Bi from the University’s School of Public Health.

MBDs cover a wide range of symptoms related to distress or impairment in essential functional areas, which include an individual’s emotional regulation, cognition, behaviour, anxiety, depression, bipolar disorder, schizophrenia, substance use, and other mental health conditions.

"From minor distress to severe disorders like schizophrenia, rising temperatures are exacerbating challenges for millions," remarked Professor Bi.

The study indicates that warmer areas, particularly those near the equator, face greater risks.

"These findings highlight the essential role of policymakers in creating targeted public health strategies to mitigate the mental health effects of climate change, considering its considerable human, social, and financial ramifications," Professor Bi added.

"Our research demonstrates that climate change will increase mental health issues beyond what population growth alone would bring about," noted first author Dr. Jingwen Liu.

The researchers advocate for immediate measures, including heat-health action plans to prepare healthcare systems for rising mental health demands, localized solutions like community initiatives, and green spaces to enhance resilience and support vulnerable populations, ensuring that those most at risk receive the necessary care during periods of extreme heat.
