Best Time for Sun Exposure.
Sun exposure is important for vitamin D synthesis, but too much sun can increase an individual’s risk for skin cancer. In a newly published study, a research team from Oslo University Hospital recommends the best times for optimal vitamin D production with minimal risk of skin cancer development are between 10:00 AM and 1:00 PM. Lead author Dr. Johan Moan adds that the common recommendations to avoid the sun altogether between 10:00 AM and 4:00 PM may be wrong.
