SaralnamaA new study shows using SPF50+ sunscreen daily can increase the risk of vitamin D deficiency. Researchers tested 639 Australian adults for a year. The sunscreen group had lower vitamin D levels than the control group. By the end, 46% of sunscreen users were vitamin D deficient compared to 37% of non-users. Experts still recommend daily sunscreen use when the UV index is 3 or higher to prevent skin cancer. People who use sunscreen daily should consider taking vitamin D supplements, especially in winter. Vitamin D deficiency is more common in southern states. Regular sunscreen use is not the only cause of deficiency. Those who rarely go outdoors or cover most skin are also at risk.
