The emotional toll of climate change is profoundly affecting the mental health of individuals, particularly in developing countries, where economies are buckling under the weight of climate-related challenges. The immediate devastation caused by floods, along with the enduring consequences of droughts and water scarcity, leads to economic turmoil, escalates poverty levels, and poses significant risks to human health. Floods, droughts, and hurricanes not only lead to physical injuries and diseases but also contribute to a rise in mental health issues. According to the Sixth Assessment Report from the Intergovernmental Panel on Climate Change (IPCC), these extreme weather events have a direct correlation with worsened mental well-being, significantly increasing anxiety levels among affected populations.
With every instance of extreme weather and each fraction of a degree increase in global temperatures, the likelihood of diseases spreading rises, potentially undoing years of progress made in global health. Vulnerable communities are often hit the hardest, facing increased mortality rates and health problems due to heatwaves and pollution, as well as the emergence of vector-borne illnesses like dengue fever. Alarmingly, air pollution alone accounts for approximately seven million premature deaths each year.
The World Health Organization (WHO) projects that climate change will likely result in an additional 250,000 fatalities annually between 2030 and 2050, primarily due to complications such as undernutrition, malaria, diarrhea, and heat stress. Without immediate and effective climate action, these dire circumstances will only intensify. Recent studies indicate that frequent exposure to extreme weather conditions and prolonged climate threats leads to a notable increase in mental health disorders—not just within at-risk communities, but across society as a whole. Anxiety and depression rank among the most prevalent mental health issues directly tied to the impacts of climate hazards, including both the immediate effects of disasters and the secondary effects of displacement and loss of livelihoods.
While the ramifications of climate change touch everyone, the youth population, in particular, experiences heightened disillusionment and anxiety as they grapple with the daunting reality of a future overshadowed by ecological crises. About 90% of the world’s 1.8 billion young people reside in developing nations that are particularly vulnerable to climate impacts. A study conducted by Bath University in 2021 revealed that 60% of 10,000 young individuals surveyed across ten countries were "very worried or extremely worried" about the state of the climate, noting that chronic stress related to climate change was exacerbating both mental and physical health challenges. If a similar survey were to be conducted today, it’s likely that the level of concern would be even higher, given the escalating climate stressors.
The nexus of trauma and depression is becoming increasingly evident as climate change continues to unfold. Pakistan serves as a poignant example of a nation grappling with severe climate vulnerabilities while also having a youthful demographic. Recurrent floods and extreme heat have thrown the country into a polycrisis marked by the destructive interplay of climate change, health, poverty, and growing inequality, further complicating the mental health landscape.
Countless individuals affected by the catastrophic floods in 2010 and 2022 have faced significant economic hardships, leading to prolonged trauma and depression. The emotional anguish experienced by those who lost family members or were forced to relocate to areas lacking social support has been immense. Young people, in particular, endure long-lasting consequences as their education is disrupted and they lose access to fundamental resources like clean drinking water. UNICEF reported that approximately 10 million children were without access to clean drinking water and essential social services for over six months following the 2022 floods. Although medical treatment for physical injuries and economic losses were addressed to some extent, there was a glaring neglect of mental health concerns during this crisis. This oversight largely stems from the insufficient mental health infrastructure within the public sector. With a limited number of psychiatrists and mental health facilities available, addressing mental health issues remains a significant gap in public health discussions in various developing countries, including Pakistan.
Moreover, awareness regarding the relationship between climate change and mental health is alarmingly low. While the evidence documenting the health impacts of climate change is robust and can assist in formulating climate strategies that consider physical injuries, the psychological consequences of environmental disasters are often overlooked, inadequately recorded, and excluded from climate policies.
To address these pressing issues, it is essential for governments to place mental health at the forefront of their agendas by allocating funds for the establishment of specialized mental healthcare facilities. The lack of healthcare services in rural and peri-urban areas increases susceptibility to diseases linked to climate change. Furthermore, discussing mental health remains a taboo in many cultures. To combat this stigma, educational institutions, local organizations, and media outlets should work together to raise awareness about mental health issues and their implications. Drawing connections between mental health and climate disasters, which are relatable experiences for many, can be particularly impactful. Just as we cannot afford to delay actions against climate change, we must also prioritize mental health—immediate action is necessary.
