This review article, assembled by a team of UV experts, indicates that UV exposure may support multiple internal systems linked to a longer healthspan, including immune regulation, cardiovascular health, metabolic balance, and neuro-endocrine function. UV exposure activates complex neuro-immune-endocrine pathways through the skin that influence systemic physiology. These effects include lowering blood pressure via nitric oxide release, modulating inflammatory and immune responses, supporting metabolic processes related to weight, glucose homeostasis, and adipose tissue function, and influencing hormonal and reproductive pathways. Large cohort studies also associate higher lifetime sunlight exposure with reduced all-cause and cardiovascular mortality, suggesting that sunlight-induced UV signaling may contribute to enhanced longevity and reduced risk of cardiometabolic and inflammatory diseases.

Vitamin D3 and marine ω-3 fatty acids supplementation and leukocyte telomere length: 4-year findings from the VITamin D and OmegA-3 TriaL (VITAL) randomized controlled trial
The American Journal of Clinical Nutrition
Analysis of data from the VITAL trial found that 4-years of supplementation with 2000 IU/day vitamin D3 reduced telomere attrition by 140 bp, suggesting that vitamin D3 daily supplementation might have a role in counteracting telomere erosion or cell senescence.

Gut-vitamin D interplay: key to mitigating immunosenescence and promoting healthy ageing
Immunity & Ageing
This review article discusses the gut microbiota and vitamin D as an emerging and vital axis influencing immune aging and age-related diseases. It highlights the dual role of gut microbiota in shaping host immunity and regulating vitamin D metabolism, alongside the significant immunomodulatory potential of vitamin D in maintaining intestinal homeostasis and barrier integrity. The findings suggest that vitamin D deficiency and gut dysbiosis accelerate immunosenescence and inflammageing, contributing to unhealthy aging and increased risk of age-related diseases.

Avoidance of sun exposure is a risk factor for all-cause mortality: results from the Melanoma in Southern Sweden cohort
Journal of Internal Medicine
This analysis of data from almost 30,000 women from the Melanoma in Southern Sweden (MISS) cohort found that nonsmokers who avoided sun exposure had a life expectancy similar to smokers in the highest sun exposure group, indicating that avoidance of sun exposure is a risk factor for death of a similar magnitude as smoking. Moreover, compared to women with the highest sun exposure, life expectancy for women who avoided the sun was shorter by up to 2.1 years.
