The changing climate in Turkey is increasing the incidence of seborrheic dermatitis

Environmental factors such as high humidity, high cloud rate and low temperature can increase the incidence of seborrheic dermatitis, the results from a Turkish study will reveal today at the 29th EADV Congress, EADV Virtual.[i]

The study aimed to investigate the correlation between seborrheic dermatitis – a common skin disease that causes an itchy rash with flaky scales - and climate data including humidity, temperature, rainfall, atmospheric pressure, cloud, and UV index. Climate data between August 2018- July 2019 was analysed and compared with the incidence of seborrheic dermatitis during the same period.

Seborrheic dermatitis incidence was highest in winter. There was a statistically significant positive correlation between high humidity, cloud and seborrheic dermatitis incidence, and a negative correlation with high temperature (P <0.001, P=0.028, P=0.024, respectively).

Dr Ömer Kutlu of the School of Medicine, Dermatology and Venereology, at Uşak University, Turkey, says: While the exact aetiology of seborrheic dermatitis remains unclear, climate change is considered one of the possible triggering factors. Our study shows that certain changes in weather conditions do indeed increase the incidence of this common skin condition.”
