How Dermatologists Fuel Chronic Disease Rates With Their Flawed Sun Exposure Guidelines

How Dermatologists Fuel Chronic Disease Rates With Their Flawed Sun Exposure Guidelines. Dr Mercola makes a compelling case to get regular small amounts of natural sunlight to reduce mortality. He even points out that there is little solid evidence that sunscreen reduces melanoma. His main point is that there is a risk of being indoors for long hours.

The notion that supplements are bioequivalent to sunshine is lacking. While I recommend supplements if UVB exposure is not available, to suggest that vitamin D can replace all the benefits of sun exposure is ridiculous. In fact, each of us responds quite differently to vitamin D supplementation – there is a 6 to 10 times difference in dosage response between individuals.

Sunscreen doesn’t prevent skin cancer:

According to an analysis by epidemiologist Marianne Berwick, Ph.D., there’s very little evidence to suggest that sunscreen use will prevent skin cancer. After analyzing a dozen studies on basal cell carcinoma, which is typically non-lethal, and the more deadly melanoma, Berwick found that people who use sunscreen tend to be more likely to develop both of these conditions. Only 2 of 10 melanoma studies found that sunscreen was protective against this condition; three found no association either way. None found sunscreen use protected against basal cell carcinoma.

There are two types of melanin gene:

Humans evolved to produce two kinds of melanin … In the mid-zone such as the Mediterranean region, people … produce eumelanin, the pigment responsible for brown or black hair and for dark skin that tans easily …

[I]n far northern Europe, humans paled, adapting to lower light … with a different type of melanin, called pheomelanin, associated with fair skin and blonde and red hair with minimal protective value, but allowing more UV to penetrate to make vitamin D. “
