Expert Conference 2024

Photochemical & Photobiological Sciences — June 4 2025 “Beneficial health effects of ultraviolet radiation: expert review and conference report” May 27–28 2024 Washington DC meeting. https://link.springer.com/article/10.1007/s43630-025-00743-6 Confirms: benefits extend far beyond vitamin D. Nitric oxide pathway confirmed. Neuro-immune-endocrine pathways confirmed. Large cohort studies — higher sun exposure associated with improved overall life expectancy confirmed. UVR effect on autoimmune disease vitamin D-independent confirmed.

University of Edinburgh — Professor Richard Weller (2024) https://regeneration-repair.ed.ac.uk/beneficial-health-effects-of-ultraviolet-radiation “Vitamin D only accounts for a tiny proportion of the benefits of sunlight.” Confirmed. Low sun exposure — risk of death similar to smoking — confirmed. Current public health advice needs reconsidering — confirmed. Scottish study — UVB in pregnancy and learning disabilities confirmed.

Journal of Investigative Dermatology — Weller (2024) “Sunlight: Time for a Rethink?” JID 144(8):1724-1732 https://pubmed.ncbi.nlm.nih.gov/38661623/ No studies link sun exposure to increased all-cause mortality. UK and Sweden epidemiological studies confirmed. Nitric oxide photomobilisation mechanism confirmed. Vitamin D supplementation trials showing little benefit confirmed.

The Full Spectrum

Frontiers in Public Health — December 2024 “Ultraviolet and infrared radiation in Australia: assessing the benefits risks and optimal exposure guidelines” https://www.frontiersin.org/journals/public-health/articles/10.3389/fpubh.2024.1505904/full Full spectrum breakdown confirmed. UVA 95% of UV at midday confirmed. Near-infrared penetration depth confirmed. Latitude gradient effect confirmed. Diabetes UVR-independent benefit confirmed.

Anticancer Research — Holick (2016) “Biological Effects of Sunlight Ultraviolet Radiation Visible Light Infrared Radiation and Vitamin D for Health” https://ar.iiarjournals.org/content/36/3/1345 Comprehensive review of all sunlight spectrum components. Human evolution in sunlight confirmed. 40+ years of sun avoidance messaging context confirmed.

Photobiomodulation

PubMed — Hamblin et al. (2020) “Sunlight and health: shifting the focus from vitamin D3 to photobiomodulation by red and near-infrared light” https://pubmed.ncbi.nlm.nih.gov/32464190/ PBM as primary sunlight health mechanism proposed. Red and near-infrared light beneficial effects in animal models confirmed. RCT preliminary evidence confirmed. Vitamin D-independent pathway confirmed.

5,000+ peer reviewed PBM studies: PubMed search: photobiomodulation Returns 5,000+ results. Clinical applications — wound healing traumatic brain injury pain management all documented.

Vitamin D

Endocrine Society Practice Guidelines Serum 25(OH)D levels: Sufficient: 30–100 ng/mL Insufficient: 20–29 ng/mL Deficient: <20 ng/mL 1 billion people globally deficient or insufficient — confirmed across multiple WHO and epidemiological sources.

ScienceDirect — Vitamin D-Independent Benefits (2021) https://www.sciencedirect.com/science/article/abs/pii/S0960076021001503 2,000 genes regulated by calcitriol confirmed. Supplement trials failing to replicate sunlight benefits confirmed. Multiple disease associations confirmed.

Nitric Oxide and Cardiovascular

Multiple Weller lab publications University of Edinburgh. UVA → nitric oxide release from skin → blood pressure reduction. Cardiovascular mortality reduction with sun exposure confirmed. Vitamin D-independent mechanism confirmed. Referenced in Weller 2024 above.

Circadian Clock

Multiple sources confirming: SCN as master clock confirmed. 480nm blue light as primary zeitgeber confirmed. Molecular clock in every cell confirmed. Circadian disruption consequences confirmed across extensive literature.

See SRC - MKUltra for blue light melatonin suppression primary citations.

SAI Connection

See SRC - Stratospheric Aerosol Injection (SAI) for documentation of how SAI would affect solar spectrum reaching Earth’s surface.

Key: SAI particles scatter UVB and alter the ratio of diffuse to direct radiation — affecting vitamin D synthesis photobiomodulation and circadian signalling simultaneously. The frequency environment disruption extends across the full spectrum.
