    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.

            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.
