Optimal Sun Exposure Tips for Boosting Vitamin D Safely
Despite abundant sunshine, nearly 42% of Americans are vitamin D deficient. The best time for sun exposure to boost vitamin D levels is between 10 a.m. and 1 p.m., when UVB rays are strongest, but it should be done with caution to avoid skin damage. Short outdoor breaks during late morning or early afternoon can help, especially for those with limited sun exposure or higher risk factors, with supplements as a backup if needed.
