Impacts of Climate Change and Air Pollution on Chronic Skin Disease

The discussion focuses on the adverse effects of climate change, particularly air pollution and heat, on chronic skin diseases. Evidence indicates that air pollution exacerbates existing skin conditions and increases the incidence of diseases like atopic dermatitis, especially in urban areas with high pollution levels. Studies highlighted include a significant link between particulate matter and a rise in atopic dermatitis cases, as well as findings from wildfires that led to increased healthcare visits for skin conditions. Additionally, sulfur and nitrogen dioxide are associated with flare-ups of atopic dermatitis. On the heat aspect, the talk emphasizes the growing severity and frequency of heat waves, particularly affecting vulnerable populations living in warmer urban microclimates. Dermatologists should be aware of how these environmental factors can impact treatment and management of conditions like hidradenitis and psoriasis, as these patients may have a diminished ability to cope with heat. A retrospective study showed a clear correlation between temperature rises and hidradenitis flares. The speaker advocates for increasing awareness, gathering data on how climate conditions affect dermatological diseases, and adjusting management strategies accordingly to better support patients affected by climate change.
