    What is this shadow longer than your tall thing ? I have never heard of it lol . Can you explain how to check it or why it is a thing that happens and is real ?

      I think that’s saying that if you go out at sunrise/sunset, the sun is on the horizon, and so your shadow will be a lot longer. In that scenario, you aren’t getting enough UV to produce the vitamin D you need.

          A shallow angle from the sun give you that long shadow, but it also gives the light lots of extra air to pass through sideways on it’s way down out of space. The extra air filters out more light, and without an intense enough light your skin won’t make Vitamin D.

          If you have a long shadow, the sunlight that gets to you has gone through much more atmosphere which attenuates the ultraviolet light. So at high/low lattitudes and during morning/evening hours the amount of uv that gets to the surface is much lower.
