2200X more problems from no UVB than too much UVB - WHO 2006

World Health Organization report from 2006


optimal = Not too much and not to little UVB

see wikipage: http://www.vitamindwiki.com/tiki-index.php?page_id=1700

Summary: Daily Adjusted Life Years

If could get less UVB - 1.5 million DALYs could have been avoided
If get no UVB 3,304 million DALYs would have been lost due to vitamin D deficiency diseases – rickets, osteomalacia and osteoporosis.

= 2200X more disability if have no UVB than if have too much UVB

What the above chart should look like using the WHO data

Figure 2.1 Schematic diagram of the relation between ultraviolet radiation (UVR) exposure and the burden of disease
A = Vitamin D insufficiency
B = Optimal
C= Skin cancers, eye disease
Horizontal line = Personal exposure to UVR relative to skin type


Points A and C represent inappropriate UVR exposure. Fair-skinned populations in Australia with high outdoor UVR exposure typify point A.
Point C represents people with insufficient UVR exposure, whose dietary vitamin D intake will also be important in determining their vitamin D status.
Point B represents optimal UVR exposure: a person with careful titration of correct UVR dose for skin type.

Diseases with increasing incidence where UVR exposure/vitamin D is inadequate:

Autoimmune diseases: Multiple sclerosis Type 1 diabetes Rheumatoid arthritis
Cancers: Prostate Breast cancre Colorectal cancer Ovary cancer Non-Hodgkin lymphoma
Psychiatric disorders: Seasonal affective disorder Mood disorders Schizophrenia

Diseases with increasing incidence where UVR exposure is excessive

Acute macular degeneration
Posterior subcapsular cataract
Nuclear cataract
Ocular melanoma

Diseases CAUSED by UVB = too much


The WHO paper states that the 2200X did not even consider DALYs due to

cancers of the colon, breast, prostate, ovary and others;
autoimmune diseases such as multiple sclerosis, type 1 diabetes and rheumatoid arthritis;
cardiovascular diseases such as hypertension, acute stroke and coronary artery disease;
endocrine disorders such as type 2 diabetes;
psychiatric disorders and disorders of mood;
lymphomas including both Hodgkin and non-Hodgkin lymphoma.
