Why the study?
Recent research indicates UV light enhances nitric oxide availability, suggesting incident solar UV radiation may lower blood pressure.

May link low sunlight exposure to higher SBP in hemodialysis; leaves open whether UV exerts direct effects independent of temperature.
Does incident solar UV radiation lower systolic blood pressure in chronic hemodialysis patients?
Incident solar UV radiation is independently associated with lower systolic blood pressure in hemodialysis patients, suggesting insufficient sunlight may be a novel risk factor for hypertension.
