The role of climate change in eczema rates and severity

ESC caught up with Ottawa-based dermatologist Dr. Mark Kirchhof for a Q&A to better understand the environmental impacts of climate change on eczema.

ESC: Is climate change impacting eczema prevalence or severity?

MK: Emerging data indicate a connection between climate change and both the prevalence and the severity of eczema, meaning how many people around the world live with eczema and how severe the eczema is.

ESC: What is causing increases in eczema cases and the severity of the condition?

MK: The hypothesis and evidence point to climate change and environmental impacts, including hotter temperatures around the world and around the year, less tree coverage and shade, as well as wildfires. Heat, along with environmental pollutants and irritants, is contributing to both the increase in people suffering with the condition and its severity.

ESC: What can we do?

MK: New research and information in this area, and globally, we are working as a community to address this problem. However, in the meantime, there are many ways for eczema sufferers to manage their condition, treat flares, and live comfortably.
