Dermatological Implications of Wildfire Smoke Exposure in Vulnerable Populations

The increasing frequency and intensity of wildfires, exacerbated by climate change, has raised significant public health concerns, particularly regarding the dermatological implications of wildfire smoke exposure in vulnerable populations. This paper reviews the complex interactions between wildfire smoke constituents—such as particulate matter, volatile organic compounds, and polycyclic aromatic hydrocarbons—and their effects on skin health. Vulnerable populations, including children, the elderly, and individuals with pre-existing dermatological conditions, are disproportionately affected by these environmental hazards. Exposure to wildfire smoke has been associated with various dermatological manifestations, including exacerbation of pre-existing conditions such as eczema and psoriasis, increased incidence of allergic contact dermatitis, and heightened risk of skin infections due to compromised skin barriers. The inflammatory and oxidative stress responses triggered by smoke exposure can lead to acute and chronic skin conditions, necessitating a deeper understanding of these mechanisms. Furthermore, this paper highlights the psychosocial ramifications of wildfire smoke exposure, including the impact on mental health and quality of life among affected individuals. The role of public health interventions, education, and policy initiatives aimed at mitigating the effects of smoke exposure is also discussed. By synthesizing current research and identifying gaps in knowledge, this study underscores the urgent need for targeted strategies to protect at-risk populations from the dermatological consequences of wildfire smoke. Ultimately, this research aims to inform public health policies and enhance community resilience in the face of increasing wildfire events, thereby safeguarding skin health and overall well-being in vulnerable populations.
