General / Off-Topic Sunlight, Vitamin D and Cancers

Hmm, wouldn't you expect a more general north-south distribution if that were the case? Looks more like there's a radioactive hot zone in the north-east or something. Florida also has a lower rate than Alaska, which surely doesn't fit that pattern. Also worth noting that the range covered by "very light blue" to "very dark blue" is only 425 per 100,000 to 460 per 100,000, so only about a 10% surplus is required to move you from one extreme of the colour scale to the other.
Stunningly, there's more cancer everywhere there's less sunlight.
This is a great topic, and I appreciate all of the useful info. I live in southern California, lifelong beachgoer, Irish heritage, and unfortunately constantly battling actinic keratosis, with several basal and squamous lesions removed. I'm curious how UV sunscreens affect vitamin D synthesis if at all. Any studies on this topic?
Well sunscreen reduces UVB penetration into the skin, so it will inhibit the rate of synthesis of vitamin D. The available studies are conflicting, but it shouldn't make that much difference. Australian Cancer Council doesn't think it stops vitamin D enough to matter. They're knowledgeable about skin cancer.
If you have a sun related skin problem though, you really need the sunscreen to keep that otherwise healthy lifestyle up.
Skin cells deep in the dermis are highly active. So they have a lot of mitochondria to make their energy. This is a problem. Mitochondria have DNA specific to them, kept unshielded out of cell nuclei. Sun exposure in the skin makes that DNA mutate faster. Radiation just pings straight into it.
Our DNA repair systems consume NAD+, which the skin makes from nicotinamide. Vitamin B3. If we supply that, we can keep the tissue repaired.
Too much nicotinamide is liver toxic though, so dosage is something you might need to ask your doctor about. I use nicotinamide as part of my anti-cancer stack, but only every other day. You can accelerate the NAD generation from it with GrapeSeed Extract, which upregulates the rate limiting enzyme in the biosynthesis pathway, and that way keep the dose low and NAD high. Or consider maybe a B3 skin cream?
Cancer also has contraindications to tanning. It is worth saying more - it is strictly forbidden any thermal procedures, including visits to the sauna, baths, etc. So, cancer is not just a disease, it is a mutation of cells in the human body there are cells with a failure in their program, because of this failure they begin to divide actively and randomly, with prolonged division over time begin to appear malignant cells. It is also not desirable to be in a place where the sun's rays fall, for example, if you have a house with large windows you need good blinds that will remove the sun's rays. Calgary blind companies - Sonata Design provide blinds for all the windows you have. It is also known that at the beach, in a solarium or in a steam room, the blood velocity increases and the blood vessels dilate. So if you have cancer, there is a strict taboo on visiting such places.

Only if you ignore precipitation. Nevada is much sunnier than Arkasas or Louisiana, for example.
Obviously, sunlight exposure isn't the only causal factor in cancer rates either, but there is still a strong correlation that is clearly evident on maps, especially once other factors are accounted for. Look up a sunlight exposure map and it's pretty close to that cancer rates map, with a couple of exceptions that can be explained by other demographic and lifestyle statistics.
Research into the effects of sunlight on our bodies continues. It isn't just vitamin D, and UV light either- infrared light at 670nm has profound biologic effects.
Tissue illuminated at that frequency generates more ATP. The mitochondria work better. Nobody really knew why, till a German scientist looked at what the light was doing to the water. H2O viscousity is markedly decreased at that frequency because of molecular excitation. At a microscopic level, water forces like surface tension are enormous, but they get removed by the light because intermolecular physics is altered.
So how does that help our mitochondria?
Mitochondria have molecular scale turbines that literally spin to produce ATP. They spin better in low viscosity water.
