Comment on Why does it feel like too much effort just to go from sitting around looking at garbage online to simply watching a film or playing a video game?

  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.

    Still I don’t understand does shadows have something to do with vitamin D ?

      No. It means how high is the sun.

      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.

  Angle of the sun. Sunlight’s not intense enough for your skin to use the radiation to help generate the D.
