Hi All-
Many of you on this board (like me) take Vitamin D for pain control and immune modulation and neuropathy. I've noted that some of you who live in climates with a lot of sun will still make comments that your Vitamin D levels are low despite sitting in the sun.
There's a recent study in Pubmed that indicates climates with A LOT of HUMIDITY may impair absorption of Vitamin D from the sun...Granted, this is just one study but I thought it might explain why some who live in hot climates can't seem to raise their levels through sun exposure....
..Interesting...

Is there a link to the study? I think that excess humidity would have the effect of preventing the vitamin D producing UV rays from reaching the cholesterol vitamin D precursor in the subcutaneous fat. In addition, high humidity weather is usually associated with lower atmospheric pressure, and that would result in a decrease in the movement of the newly formed vitamin D in the skin into the subcutaneous lymph channels for eventual movement into the bloodstream. Makes sense, from a physics standpoint...

Wow--that is fascinating. I just found out my Vit D was still deficient, after 3 months of supplementing. And I do get sun exposure--not a ton because of the heat and migraines, but enough.
