Climate change is likely to make things worse for people dealing with eczema, according to international research. Scientists searched previous studies on links between climate and air pollution and the number of patients seeking help for their eczema to assess the evidence. They say, looking at 42 studies, there is evidence of moderate to high quality that air pollution is linked to increased eczema severity, as well as extreme temperatures, either hot or cold. Increased rain and humidity may also be linked to eczema, they say, adding that efforts to reduce air pollution and mitigate climate change could help improve outcomes for people with eczema.
