About UV Index & Vitamin D

The UV index is a sunburn-weighted score, not a measurement of the light. It tracks UVB closely and is nearly blind to UVA, so it is a useful proxy for burn risk and vitamin D timing, and a poor guide to everything else sunlight does. Sunlight is Life uses a solar physics engine to model the actual sunlight reaching you, and shows the UVA and UVB separately.

Our vitamin D calculator uses real-time UV data along with your skin type and exposure time to estimate how much vitamin D your body can produce.
