Reduced Solar Radiation Associated with Increased Use of Systemic or Phototherapy in Psoriasis: Study

A new study published in the journal of Photodermatology, Photoimmunology and Photomedicine showed that people with psoriasis are more likely to receive systemic treatment or phototherapy when there is less ambient sun exposure.

Seasonal variations in the severity of psoriasis, with it getting worse in the winter and getting better in the summer, point to the potential benefits of ambient sun radiation. Furthermore, "climate therapy," which involves purposeful exposure to sunshine, lessens the severity of psoriasis. Remarkably, Okun and Okun's research of psoriasis clinical trial participants revealed no connection between the degree of psoriasis and the amount of UV light present at the study locations.

Additionally, studies discovered no significant link when they analyzed the prevalence of psoriasis in existing research by the mean country latitude. Tus, Brad Woodie and colleagues evaluated the relationship between the severity of psoriasis therapy and yearly local sun radiation using a representative sample of the US.

For their study, the research team analyzed de-identified participant data from the 'All of Us' Research Program, version 7 of the National Institutes of Health. Information that has previously been gathered between 2017 and 2022 was incorporated in this program. The group aimed to reduce the number of study participants who could need systemic immunosuppressive treatments for unrelated illnesses.
