According to a study, up to 57% of adults suffer from a vitamin D deficiency, despite seemingly adequate sunlight. This raises a critical question for many who seek to balance sun safety with nutrient needs: Can you still absorb vitamin D in the shade?

A common misconception is that sitting near a sunny window is enough to produce vitamin D, but glass blocks the essential UVB rays required for synthesis. While indirect sunlight outdoors provides some scattered UVB exposure, its efficacy is significantly lower than direct sun.
