While we’re often warned about the dangers of sun exposure, sunlight also activates vitamin D—an essential nutrient linked to far more than just bone health. Growing research connects low vitamin D levels with an increased risk of heart disease, stroke, and high blood pressure.
A study published in Circulation (January 2008;117(4):503–511) examined 1,739 adults from the Framingham Offspring Study. None had heart disease at the beginning of the research. Over 5.4 years, 120 participants experienced a heart attack or stroke. Those with vitamin D levels below 15 ng/mL were 62% more likely to have a cardiovascular event than those with higher levels.
Additional research from the Archives of Internal Medicine (June 9, 2008;168(11):1174–1180) analyzed data from the Health Professionals Follow-up Study. Men aged 40–75 with vitamin D levels below 15 ng/mL had a 2.4-fold higher risk of heart attack compared to those with levels above 30 ng/mL—even after adjusting for other risk factors such as smoking and family history.
These findings suggest that maintaining healthy vitamin D levels may be important for protecting cardiovascular health.
