Dave says:

As we know, UVB rays from the sun are not able to penetrate glass. Is there any research on finding an alternative to glass that would allow UVB rays to reach a person's skin whilst indoors?

Vitamin D is best produced via sunlight and since lots of people do not have access to a garden, then an alternative window pane material might effect a general improvement in health worldwide, both in relation to Covid and lots of other health issues.

What do you think?

Hi Dave!
🙂

I am Not aware of any Alternatives to Glass or Plastic sheet coverings.
👎

But i Do know the Best time to soak up the Sun is at Midday during summers.
At Noon the Sun is at it's highest point & it's UVB rays are more Intense.
☀️
Hence one would need to spend less time in the Sunlight to make sufficient Vitamin D.
👍

Perhaps one could also consider foods rich in Vitamin D as a supplementary diet.


P.S. - There is an Alarming side to this OP.
UVB Rays vs UVA Rays.
I found the below Link quite Illuminating & Informative.
I would Request All to have a quick look.

Quartz does let UV-B through, but it's very expensive and not very transparent to normal light:

You'd be a lot better off just taking vitamin D pills! They don't cause cancer.
