    Vitamin D deficiency as well!

    Nearly 42% of adults in the United States have a vitamin D deficiency. This figure rises to almost 63% in Hispanic adults and 82% in African American adults.

    If your shadow is longer than you are tall, you are not getting enough ultraviolet radiation to produce vitamin D. You need about 15 minutes a day.

    Some of the symptoms are fatigue and depression

        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.

      I found out last doctor’s appointment my vitamin d is insanely low so I started taking a supplement this week and it’s made a world of difference already! Highly recommend trying it out if you feel burnt out and low energy all the time especially if you spend a lot of time inside. Its also relatively pretty cheap all things considered which is nice.
