Prevalence of Mental Health Issues and Air Pollution in Europe

The European Health Interview Survey reveals that mental health concerns are widespread, with one in six EU residents experiencing problems related to mental health. Notably, 7.2% of the population suffer from chronic depression, underscoring the significance of this issue (EEA, 2025). In 2023, air pollution was attributed to 7.9 million deaths globally, with 86% of these fatalities resulting from non-communicable diseases, highlighting the far-reaching health impacts of air pollution (HEI, 2025).

Effects of Urban Air Pollution on Mental Health Resilience

Urban air pollution has a notable impact on the resilience of mental health, affecting cognitive abilities, emotional stability, and overall psychological well-being in urban populations. Exposure to common pollutants; including fine particulate matter (PM2.5), PM10, nitrogen dioxide (NO2), sulphur dioxide (SO2), and ozone, is consistently associated with a range of adverse mental health outcomes. These include increased rates of depression, anxiety, stress, as well as reductions in life satisfaction and self-esteem.

Susceptibility and Vulnerability

Mental health resilience, defined as the ability to maintain or regain mental well-being in the face of adversity, is particularly susceptible to the effects of air pollution. A Bayesian network study focused on older adults in China found that fine particulate matter is the most critical pollutant diminishing short-term mental health resilience. The research identified women aged 65–75 and individuals with lower educational attainment as being especially vulnerable to these effects (Song et al., 2025).

Indirect Impacts on Urban Pollution

The psychological toll of urban pollution extends beyond direct exposure, operating indirectly by deteriorating sleep quality, reducing life satisfaction, impairing physical health, and hampering cognitive functions that mediate mental health resilience. These indirect effects are notably pronounced among middle-aged and older adults (Zou et al., 2025).

Role of Perception and Subjective Experience

Perceptions of air pollution can themselves become psychological stressors, at times exerting a greater influence on health outcomes such as asthma than objective pollution levels. This observation suggests that mental health resilience is shaped not only by environmental conditions but also by subjective experiences and individual perceptions (Clougherty and Ocampo, 2023).

Benefits of Urban Greenery and Forestation

Urban greenery and forestation are vital in fortifying mental health resilience. These elements help reduce air pollution through the absorption and interception of particulate matter and alleviate urban heat island effects, which can otherwise intensify environmental stress. Additionally, green spaces provide psychological benefits, contributing to improved well-being among city residents.

Strategies to Strengthen Mental Health Resilience

Mitigating the impact of air pollution on mental health resilience requires a holistic approach involving policy, technology, urban planning, and community engagement. Essential actions include enforcing stricter air quality standards, encouraging public transport and the use of electric vehicles, implementing advanced filtration systems, expanding green spaces within cities, and devising targeted interventions for vulnerable groups identified by demographic disparities in resilience ( Kapoor et. al., 2024; Song et. al.,2025). This integrated strategy is aimed at reducing exposure to pollutants and enhancing pathways to mental health resilience, ultimately fostering improved urban well-being and sustainability (Kapoor et. al., 2024).
