Have you felt what it’s like to not soak in UVB rays for days, even weeks, in a row? It doesn’t feel good. It is sad. It is dark. It is depressing. Literally. Have you seen Dracula? He’s pale. He’s pissed. He’s very, very moody.
Oh wait. For most people, that’s the norm. I had quite a few episodes of depression after severals days of not being in the sun, particularly during finals week in college.
But we’re not most people. So we’re going to figure out how to get a steady supply of UVB.
My next question about UVB, vitamin D, and cholesterol sulphate is, what’s the deal with not having access to the “right” type of sunlight throughout the year? Do humans really need D and sulphate constantly then? Would we be fine without it, as perhaps our ancestors may have been?
Dr. Stephanie Seneff of MIT gives a lot of compelling reasons why we do need these two supernutrients. Cholesterol sulphate keeps red blood cells together. It also delivers cholesterol and sulphate to all cells.
But this doesn’t explain the fact that we’re not all living with regular UVB light. If Homo sapiens evolved without it all the time, do we need it that much? We’re on the same Earth as our earliest ancestors, right? Maybe not.
Think geographically, historically.
Homo Sapiens are currently believed to have evolved in the South and East African regions 100,000 years ago. This area, shown in dark blue, straddles the equator. Ethiopia at the top, and South Africa at the bottom.
The capital cities are Addis Ababa in the north, and Pretoria in the south. Guess what. Both see the sun at well above 50 degrees horizontal, at some point during the day, through all times of the year.
That doesn’t seem like a coincidence. It makes sense to me that our species birthed, survived, and thrived in a place that was ideal in significant ways. Regular UVB exposure would guarantee vitamin D and cholesterol sulphate production within the body.
But from a limited perspective, the fact that this region receives optimal sun position throughout the year seems to beat the argument of coincidence. Chance, yes.
Evolution patiently progresses on the emerging footholds of chance. Something, maybe many things, presented in the environment to allow the first homo sapiens to thrive and multiply. Perfect sunlight could have been one of those chance elements.
If we say our skin makes life-supporting molecules from the sun, and food doesn’t give us that, and these things are critical for our survival and wellness, then I will say we are made of the sun. If we are made of the sun, we must feed on the sun. At fifty plus degrees, of course.
