Covid again !!

[ponytug]

I'm no expert by any measure. All I have to go on is what they told my son in law when he had Covid and what the nurses at our health department and local VA clinic said. The nurses said anybody living north of the Tennessee/Georgia line could not get enough sunlight for their body to make sufficient vitamin D. Don't know if it is true or not.

Hmm... I don't think that is the case, but there are nuances, e.g. less time for fair skin, more for darker skin. A person gets quite a bit of vitamin D even from short exposures on small areas of skin.

Nice article here;

Ask the Doctors - How much sunshine do I need for enough vitamin D?

www.uclahealth.org

It mentions several studies using realistic areas of skin (e.g. not much) in various geographic locations. One thing not mentioned in the article is that vitamin D is a steroid type chemical, converted from cholesterol to its storage form that is stored in the liver, before being converted to the active form in the kidneys. Lots of ways to go sideways if the body isn't working properly.

Vitamin D 101 — A Detailed Beginner's Guide

This is a detailed article about vitamin D and its health effects. Vitamin D actually functions as a hormone, and deficiency is incredibly common.

40+% is said to be "deficient" in Vitamin D, but the definition of deficiency is under some strong debate at the moment.

All the best,

If your hemoglobin is above 14, you're probably getting enough vitamin D.

If you donate blood, you will get a free hemoglobin count.

1/2 hour in the sun with exposed face and arms lets your own body produce all the Vit D you need.
That is hard to do in winter,

I don't have that issue. My work keeps me outside for at least a couple hours each day, so I get plenty of sunshine.

I've had to start wearing a light weight boonie hat whenever I go outside after my dermatologist fogged my whole forehead with freeze spray on my last visit

Donating blood is great!

I'm sorry, but how is hemoglobin related to vitamin D? There is a big study showing it has no effect;

Effect of Vitamin D Supplementation on the Hemoglobin Level in Chronic Kidney Disease Patients on Hemodialysis: A Systematic Review and Meta-Analysis - PMC

The objective of this study was to evaluate the impact of vitamin D supplementation on hemoglobin levels (Hb) in patients with chronic kidney disease (CKD) undergoing hemodialysis. A systematic search was conducted in electronic databases ...

As far as I am aware, Vitamin D turns into calciferol as its active form for regulating calcium and suppressing tumor growth for many cancers.

The best part about all this "illness and health" medical talk is.....

Life remains a miracle!
And a gift

I thought it improves iron saturation and anemic problems which improves hemoglobin.

But after a little research it appears I have been wrong for a very long time.

Thanks for pointing that out.

Just a note

Black pepper and turmeric are good for you!

And don't forget,
fully 1/2 of all doctors graduated in the lower 50% of their class!

@bigtiller No worries! I am always hoping to learn something new.

All the best,
