The temperature might not be the only thing plummeting this winter. Many people also will experience a decrease in their vitamin D levels, which can play a role in heart disease, according to a new review article.
Low vitamin D may be a factor in heart disease, says researcher.
Vitamin D deficiency results in part from reduced exposure to sunlight, which is common during cold weather months when days are shorter and more time is spent indoors. "Chronic vitamin D deficiency maybe a culprit in heart disease, high blood pressure and metabolic syndrome," says Sue Penckofer, PhD, RN, study author and professor at Loyola University, Chicago.
Penckofer uncovered a number of studies that linked vitamin D deficiency to heart disease. These studies found rates of severe disease or death may be 30 to 50% higher among sun-deprived individuals with heart disease. Penckofer and colleagues concluded that diet alone is not sufficient to manage vitamin D levels. Treatment options to correct this level, such as vitamin D supplements,may decrease the risk of severe disease or death from cardiovascular disorders.
"Most physicians do not routinely test for vitamin D deficiency," said Penckofer. "However, most experts would agree that adults at risk for heart disease and others who experience fatigue joint pain or depression should have their vitamin D levels measured."
