Emerging preclinical findings suggest that some sun exposure is necessary for optimal metabolic health
Both human and murine studies report that multiple exposures to sub-erythemal UV radiation can increase the diversity of the gut microbiome
To our knowledge, this is the first study to show that the reported 25(OH)D concentration may be influenced by both age and assay type
There is a greater prevalence of multiple sclerosis (MS), a neurological autoimmune condition, in populations living further from the equator, hypothesised to be due to reduced sunlight exposure. There exists a proven sunlight surrogate therapy for dermatological inflammatory conditions, in the form of narrowband NB-UVB phototherapy. Yet, there is a paucity of randomized trials of the therapeutic delivery of NB-UVB beyond dermatology for conditions with a systemic inflammatory component.
Low vitamin D intake and prevalence of serum 25-hydroxyvitamin D concentration <50 nmol/L among Aboriginal and Torres Strait Islander peoples highlight a need for public health strategies to improve vitamin D status. Since few foods contain naturally occurring vitamin D, food fortification could be a suitable strategy. We aimed to model vitamin D food fortification scenarios among Aboriginal and Torres Strait Islander peoples.
Little is known about how sun exposure may affect the maternal skin barrier during pregnancy when many hormonal and physiological changes occur. In this longitudinal observational study, 50 pregnant women were recruited at 18-24 weeks' gestation, 25 in summer-autumn, and 25 in winter-spring. At three time points in pregnancy at 18-24, 28-30, and 36-38 weeks' gestation, participants completed a validated sun exposure questionnaire and had skin permeability and surface pH measured on the volar forearm.
Researchers from The Kids Research Institute Australia and Cancer Council WA will team up on two projects aimed at identifying the most effective public health messaging for young people around SunSmart behaviours and how to stop vaping.
Ultraviolet radiation is the leading preventable cause of skin cancer, and early-life exposure increases long-term risk. Despite this, guidelines on sun protection for children and young people are inconsistent.

New initiatives to develop a standard reference method and the assignment of "true" values to samples provide a solution to these problems.
