Maui Wildfires: Depression & Anxiety Surge – New UH Study 2024

The psychological impact of the 2023 Maui wildfires continues to ripple through communities, extending far beyond the immediate burn zones and affecting residents’ mental wellbeing with significant increases in depression, anxiety and even suicidal thoughts. A new study published March 11 in JAMA Psychiatry by researchers at the University of Hawaiʻi at Mānoa details the scope of this ongoing mental health crisis, linking it closely to disruptions in housing and income.

Beyond the Flames: A Wider Mental Health Impact

The study, which examined data from 2,453 adults – 1,535 who experienced the wildfires firsthand and 918 from unaffected areas of Hawaiʻi – paints a stark picture. Residents living within the areas directly impacted by the fires faced a 53% higher risk of depression and a 67% higher risk of anxiety compared to those who were not directly exposed. However, the findings reveal a broader pattern of distress. Those living outside the burn zones on Maui also experienced significantly elevated mental health risks, with more than double the risk of suicidal thoughts. This suggests the trauma isn’t limited to those who lost homes or businesses, but extends to the wider community grappling with the aftermath.

The data was collected between January 2024 and February 2025 through the Maui Wildfire Exposure Study (MauiWES) and the UH Economic Research Organization’s (UHERO) Rapid Health Survey. Researchers found that over half of the increased risk of depression and anxiety could be attributed to housing instability and loss of income. Notably, being employed offered a strong protective effect against these mental health challenges, as well as suicidal ideation.

Socioeconomic Disruption as a Key Driver

“These findings display that the wildfire’s psychological toll is not confined to the areas that burned,” explained lead author and UHERO Professor Ruben Juarez. “The social and economic disruption—especially housing instability and income disruption—is driving much of the distress we see across the community.” UH News reports that this underscores the interconnectedness of physical disaster and mental wellbeing.

The study highlights a critical point often overlooked in disaster response: the long-term psychological consequences extend far beyond immediate physical damage. The loss of a home isn’t just a material loss. it’s a destabilizing event that can trigger profound anxiety and depression. Similarly, job losses or reduced income create financial strain that exacerbates mental health vulnerabilities. This is particularly relevant in Maui, where the tourism-dependent economy was already facing challenges.

Understanding the Study’s Scope and Limitations

It’s important to understand the methodology of this research. The study is observational, meaning it identifies correlations between wildfire exposure and mental health outcomes, but it cannot definitively prove causation. Although the researchers controlled for various factors, there may be other unmeasured variables contributing to the observed effects. The sample population, while substantial at 2,453, represents a specific geographic area and may not be fully generalizable to other communities affected by wildfires.

the study relies on self-reported data, which is subject to recall bias and social desirability bias. Participants may have underreported or overreported their symptoms, or may have been hesitant to disclose sensitive information. The timeframe of data collection, January 2024 to February 2025, captures the immediate and short-term impacts of the wildfires, but the long-term mental health consequences may not fully manifest for years to come. The University of Hawaiʻi News provides further details on the study’s methodology.

Climate Disasters and Systemic Impacts

Co-author and John A. Burns School of Medicine Professor Alika K. Maunakea emphasized the broader systemic implications of climate-related disasters. “Climate disasters affect biological, social and economic systems at the same time,” she stated. “If we only rebuild structures and do not stabilize housing, employment and mental health services, we leave communities vulnerable long after the smoke clears.” This points to the need for a holistic approach to disaster recovery that addresses not only physical infrastructure but also the underlying social and economic factors that contribute to mental health vulnerabilities.

This perspective aligns with growing recognition within the public health community that climate change is not just an environmental issue, but a significant threat to mental wellbeing. Extreme weather events, such as wildfires, hurricanes, and floods, can displace communities, disrupt livelihoods, and create widespread trauma. The psychological impacts of climate change are often referred to as “climate anxiety” or “eco-grief,” and can affect individuals of all ages and backgrounds.

What Comes Next: A Multi-Faceted Response

The findings from this study underscore the urgent need for increased mental health support in Maui and other communities affected by wildfires. This includes expanding access to mental health services, providing financial assistance to those who have lost their homes or jobs, and addressing the underlying housing crisis.

Looking ahead, continued surveillance of mental health trends in Maui is crucial. The MauiWES study provides a valuable baseline for tracking the long-term impacts of the wildfires, and ongoing data collection will help inform targeted interventions. Further research is needed to identify the most effective strategies for promoting resilience and mitigating the psychological consequences of climate-related disasters. The Centers for Disease Control and Prevention (CDC) offers resources on coping with stress during and after disasters, and provides guidance on how to seek help if you are struggling with your mental health.
