Interesting, the linked paper [0] does show they controlled for physical activity here, since I would assume someone who gets more sun exposure, is outside more.

If they really have controlled for that factor, shouldn't we see similar results from people with sedentary lives, but high UV exposure? (possibly by regular use of tanning beds or the like?) Being prescribed UV exposure is an interesting idea for the future.

In sunlight you also get lots of red and infrared, and there's quite a bit of research on the benefits of that. To replicate sunlight you'd also need bulbs for those frequencies.

It's certainly plausible, but there's a lot of confounds.

Broad-spectrum vs tanning.

And outside also gets lower CO2 and VOC.

I feel like they should prescribe sunlight for prisoners. I was held for 10 years without seeing the sun, and many jails and prisons are built on budgets that don't allow for any sunlight.

Is it just full spectrum light or specific UV sections?

I wonder if future building codes will require some type of intermittent full spectrum or UV light in certain areas. Maybe in a bathroom with a timer that shuts it off a few seconds after someone enters.

> Vitamin D is manufactured in our bodies when the UVB rays in sunlight react with a chemical in the skin called 7-dehydrocholesterol. Bone and muscle cells use it to regulate levels of calcium and phosphorus, which are needed to keep them strong and healthy

If you are at all active over age 30 — by which I mean you EVER run, jump, or otherwise put pressure on your spine — you need to get lots of sunlight.

Most people have insufficient if not downright deficient levels of vitamin D. Spondylolysis and eventual spondylolisthesis is not a prognosis you want for your back.
