The impact of climate change on atopic dermatitis and mental health comorbidities: a review of the literature and examination of intersectionality

Abstract

Climate change, fueled by increasing concentrations of greenhouse gases, is associated with rising temperatures, extreme weather events, increased aeroallergen production, and air pollution. Our understanding that many inflammatory cutaneous diseases carry important mental health comorbidities is expanding. Simultaneously, the detrimental impacts of climate change on human health are now widely recognized as a global public health crisis. Importantly, these climate-associated phenomena exacerbate the environmental triggers of atopic dermatitis (AD) and are also associated with amplification of comorbid mental health conditions in AD including depression, anxiety, trauma-related disorders, and psychotic spectrum disorders. This review is the first to examine the nexus of climate change, atopic dermatitis, and mental health comorbidities and emphasizes the disproportionate impacts of climate change in vulnerable and marginalized populations.
