This article presents a critical review of the health impacts of wildfire smoke exposure, based on a comprehensive analysis of 53 epidemiological studies. The review highlights the significant health effects of wildfire smoke, including respiratory and cardiovascular diseases, asthma exacerbations, and increased hospital admissions. The studies reviewed include both short-term and long-term effects of exposure to wildfire smoke, as well as the impact on vulnerable populations such as children, the elderly, and pregnant women. The review also discusses the effects of wildfire smoke on mental health, including increased stress and psychological distress. The studies reviewed were conducted in various regions, including Australia, Brazil, the United States, and Indonesia. The review concludes that wildfire smoke exposure has significant health impacts, and that further research is needed to better understand the mechanisms of these effects and to develop effective interventions to reduce the health risks associated with wildfire smoke. The review also emphasizes the importance of improving air quality monitoring and public health policies to protect vulnerable populations from the health risks associated with wildfire smoke.This article presents a critical review of the health impacts of wildfire smoke exposure, based on a comprehensive analysis of 53 epidemiological studies.
