A global observatory study found that 42.6% of 136 participating countries reported climate-related changes in skin disease patterns. These findings highlight a growing health burden that varies significantly by a nation’s income level.
Why it matters
Higher temperatures and humidity directly increase sweating and irritation, while shifting rainfall patterns alter the habitats of insects that carry skin-infecting pathogens. Understanding these trends is critical for developing localized surveillance and patient education strategies.
A study of 136 countries presented at the 2026 EADV Congress found that 42.6% reported climate-related skin changes. These included increases in heat rash in 81.0% of affected countries and inflammatory skin conditions in 75.9% of them, though these findings are observational.
The players
Global Access to Skin Health Observatory
An international research initiative focused on tracking global trends in dermatological conditions and access to care.
World Health Organization
The United Nations agency responsible for international public health, which members participated in this global study.
The details
Rising heat and humidity can compromise the skin barrier through excessive perspiration and prolonged moisture, leading to frequent heat rashes and inflammatory flare-ups. Simultaneously, changing environmental conditions expand the ranges of vectors that transmit infectious skin diseases. These physiological stresses disproportionately affect regions with fewer resources for infrastructure or adaptive dermatological care.

Health Landscape
This study expands the work of the Global Access to Skin Health Observatory by providing the first broad, cross-income data on climate-related dermatology. It shifts the focus from localized outbreaks to a global pattern that links environmental health to specific, measurable skin conditions.
If you notice new or persistent skin irritation, heat rashes, or inflammatory patches, it is worth discussing with your doctor how your local environment might be contributing to your symptoms. Being aware of these climate-linked patterns can help you and your physician better identify potential environmental triggers for your skin health.
The takeaway
Climate change is increasingly linked to measurable increases in heat rashes and inflammatory skin conditions across the globe. Monitor your skin for persistent changes, especially during heat waves or periods of high humidity, and report any concerns to a dermatologist.
