This literature review and meta-analysis found that both vitamin D insufficiency and deficiency were significantly associated with an increased risk of Parkinson’s disease when compared with controls. Meta-data analysis showed that those with a vitamin D level below 20 ng/ml had a 2.5-fold increased risk of developing Parkinson’s disease. The study also found that at least 15 minutes of sunlight exposure per week was significantly associated with a reduced risk of Parkinson’s disease.

Vitamin D deficiency and depression in adults: systematic review and meta-analysis
The British Journal of Psychiatry
Vitamin D is involved in various brain processes, and vitamin D receptors are present on neurons and glia in areas of the brain thought to be involved in the pathophysiology of depression. A systematic review and meta-analysis of 14 observational studies, that included a total of 31,424 adults, found that there were lower vitamin D levels in people with depression compared with controls, and there was an increased odds ratio of depression for the lowest v. highest vitamin D categories.

Narrow-band ultraviolet B radiation induces the expression of β-endorphin in human skin in vivo
Journal of Photochemistry and Photobiology B: Biology
Sub-erythema narrowband UVB exposure can cause a meaningful increase in Beta endorphins in human skin 24 hours after exposure. Beta-endorphin is primarily utilized in the body to reduce stress and pain and has also been shown to positively impact depression and mental health.

Vitamin D and Cognitive Impairment in the Elderly U.S. Population
The Journals of Gerontology: Series A | Oxford Academic
This study using data from 3,325 adults aged 65 and older found that people with lower vitamin D levels had a higher risk of cognitive impairment. Compared to those with sufficient vitamin D, the risk was similar for those with slightly low levels, 1.4 times higher for those with a deficiency, and nearly 4 times higher for those with severe deficiency. The overall trend was statistically significant.
