A study from researchers at a UAE university, reported in Foods, links sun avoidance and low vitamin D intake with higher anxiety levels. The investigation adds to a growing body of evidence exploring how nutrient status can influence mental well-being, alongside the well-established roles of vitamin D in bone health and various chronic diseases.
Vitamin D primarily helps the body absorb calcium and phosphorus from food through the walls of the small intestine. Beyond its traditional functions, accumulating clinical data suggest that low vitamin D levels may correlate with an elevated risk of conditions such as diabetes, cardiovascular disease, and certain cancers. Researchers emphasize that vitamin D likely influences mood regulation in several indirect ways, though the exact mechanisms remain a topic of ongoing study.
In this study, data came from a survey of 386 female students who provided information about their diet over the previous month, the amount of time they spent in the sun, and their mental health status. The researchers then examined associations between dietary vitamin D intake, sun exposure, and anxiety indicators.
Findings indicated that participants who spent less time in the sun and consumed fewer vitamin D–rich foods tended to report higher levels of generalized anxiety. The results highlight a potential link between sunlight exposure, nutrient intake, and anxiety symptoms in this population, contributing to broader discussions about how lifestyle factors relate to mental health outcomes.
Experts caution against self-prescribing vitamins or supplements without professional advice, noting that improper use may fail to produce benefits and could even pose risks. Practical guidance suggests increasing safe sun exposure while protecting the skin from harmful rays, and pursuing vitamin intake through a balanced diet or medical guidance when needed. As with all health matters, individuals should seek personalized recommendations from healthcare providers to address sun exposure, nutrient status, and mood concerns effectively.
