The first part of this video is a little bit technical, but don’t be put off by all the scientific names. Keep watching and you’ll learn why Vitamin D may be useful against our favourite virus. You’ll also learn about its importance for other conditions, such as osteoporosis. I most definitely did not know that.
The thing I found most interesting was the explanation about why people in different geographic locations may be Vitamin D deficient. Apparently, it’s all due to the season, the angle of the sun as it hits the earth, and a country’s distance from the equator.
The video talks about the USA, but I was interested in Australia, so I went looking for a map of the world showing the equator. Then I copied the area from the equator to roughly the middle of the USA. This was the distance from the equator that gets sufficient Vitamin D in summer and winter.
Next, I placed the copy next to Australia. This is what it looks like:
Zooming in on my home town of Melbourne, we get this:
I drew the green line across from the subset map to see if Melbourne does, in fact, fall within the area that receives enough Vitamin D in winter. It does, but only just, and Tasmania seems to miss out entirely.
So yes, we all need Vitamin D, for a variety of health reasons, but no, not all of us can get it from the sun during winter. And if we go from house to car to office and back again, then there’s a good chance we won’t be getting enough Vitamin D, even in summer.
If Covid-19 has taught us anything, apart from how to bake bread, it’s that we can’t rely on technology to save us from everything. Sometimes, living an old fashioned, healthy lifestyle really is the best medicine.
