This study that looked at the mental health of operating room nurses, who had little sunlight exposure due to their long work hours, found that this population had poorer mental health than the general population. The study found that poor mental health was associated with less sunlight hours, worse sleep regularity, and increased chronic disease. As the duration of sunlight exposure increased, survey respondents’ mental health status improved.

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.
