ULTRAVIOLET LIGHT: MYTHS AND FACTS
UV intensity is now forecast in population centers daily.
The US Environmental Protection Agency (EPA) suggests that when outdoors we should "protect ourselves against ultraviolet light whenever we can see our shadow".
And many physicians give their patients the same warning. This is terrible advice.
...
As a result of the EPA’s kind of advice, ... we slather our skin with sunscreen for even brief sun exposure.
People who engage in these practices are ruining their disposition and health.
The phobia arose after investigators anaesthetized animals, propped their eyes open and shined intense UV light into them; this damaged their retinas.
Excessive exposure to one kind of ultraviolet (shorter-wave, germicidal UVC) can damage tissue.
But the EPA makes the ridiculous leap from that truth to the conclusion that we should avoid all UVC.
UVC is found in tanning salons and halogen lamps.
In fact, the trace amounts of UV radiation in natural daylight are required for physical and mental health, civilized behavior, muscle strength, energy and learning.
Sunlight, in moderation, improves immunity and stimulates our metabolism while decreasing food craving, and increases our intelligence.

A paper published in the British Journal of Cancer shows that from 1957 to 1984 the incidence of malignant melanoma in Norway increased by 350 per cent for men and 440 per cent for women.
During the same period there was no change in ozone levels over Norway, nor any significant change in annual exposure to ultraviolet radiation from the Sun
....
"What is clear, however, is that there is a great deal of ill-informed comment on the subject of ozone depletion and, for that matter, sunbathing.
Should depletion of the ozone layer ever become a cause for real concern, then some people might develop cancer who might not have, had there been no depletion, but until this happens there is much more to be gained from investigating the real causes of skin cancer and encouraging safe sunbathing than in being preoccupied with the state of the Earth’s upper atmosphere and blaming everything on the Sun.
Diet and lifestyle play a far more significant part in the genesis of cancer than is currently recognized.
The same can also be said about another condition that is supposed to be on the increase because of ozone depletion--that of senile cataract."
Note that even low exposure to UVB significantly increases the risk of cataracts, but only with the consumption of a Western junk food diet rich in unsaturated fats and their oxidized products.
Those who consume a more sensible diet, and supplement it with vitamins C and E, do not get cataracts even from lengthy sun exposure.
PHOTOBIOLOGY
Starting from a high-school hobby of time-lapse photography, the late John N. Ott, DScHon, founded the new science of photobiology.
He was active into his tenth decade.
Dr Ott’s last book, one of many publications, is Light, Radiation and You:
How to Stay Healthy (1990). In it he wrote:
"Mankind adapted to the full range of the solar spectrum, and artificial distortions of that spectrum--malillumination, a condition analogous to malnutrition, may have biologic effects."
In an interview published in 1991, he noted:
"There are neurochemical channels from the retina to the pineal and pituitary glands, the master glands of the whole endocrine system that controls the production and release of hormones.
This regulates your body chemistry and its growth, all organs of your body, including your brain, and how they function."
The critical reader will ask: where are the controlled, scientific tests supporting Dr Ott’s statements?
The answer to that question is: who can make money promoting sunlight?

Two hours of bright light in the evening can sometimes cure symptoms such as weight gain, depression, carbohydrate craving, social withdrawal, fatigue and irritability.
I. Ultraviolet Deprivation Health Effects
First, let’s consider the health effects of ultraviolet deprivation.
Indoor Lighting and Melanoma
Malignant melanoma is often alarmingly but wrongly blamed on sun exposure.
The dangerous kind, called skin cancer, is ultimately fatal if not corrected.
A study by the US Navy found the most melanoma in people who worked indoors all the time.
Those who worked both outdoors and indoors some of the time had the lowest incidence.
Also, most melanomas appeared on parts of the body that are seldom exposed to sunlight.
The inference is that both very high and very low exposures to UV light can be harmful--and moderate exposure is healthful.
Sunscreens and Melanoma
Sunscreens block out only UVA and UVB, which we all need in trace amounts, but not the potentially dangerous, germicidal UVC.
No commercial sunscreens have been proved safe.
Their chemicals penetrate the skin into the circulation and add to the burden of toxins to be detoxified.
Commercial sunscreens increase the risk of melanoma by causing mutations when the cells’ chromosomes interact with the chemicals and the light.
Natural sunscreens, as well as commercial ones, curtail needed uptake of vitamin D3 from UVB, increasing the risk of the bone-thinning disease osteoporosis.
Moreover, Lita Lee, PhD, notes:
"Mounting evidence indicates that many of them [sunscreens] contain carcinogens and that the rise of skin cancers parallels the increase in sunscreen usage.
The only sunscreen I recommend is coconut oil, although, believe me, you cannot slather this oil on your skin and bake in the sun all day.
Adding a little iodine to the coconut oil for the first week of summer gives added protection; however, do not use the iodine for more than a week, as continued use will inhibit your thyroid function. In my opinion, the only other safe (non-carcinogenic) sunscreen would be one containing titanium dioxide."
Fluorescent Lighting and Melanoma
A study published in the prestigious medical journal Lancet and a Russian study found that fluorescent light rather than sunlight promotes melanoma, proportionately to the time of exposure.
In the Lancet study, among a sample of nearly 900 women, those who worked indoors under fluorescent lighting had 2.l times higher melanoma risk (95% confidence interval, CI, 1.32 to 3.32) than others.
Among women exposed for 20 years or more, the relative risk (RR) was 2.6 (95% CI, 1.2 to 5.9).
Relative risks were lower in women who had been most heavily exposed to sunlight, both playing outdoors as children and sunbathing as adults.
In a smaller sample of men, the RR for fluorescent lights with 10 or more years’ exposure was 4.4; and for those who had spent the least time in the sun while children, the RR was 7.3.
And so we see that lengthy exposure to full-spectrum sunlight, including trace UVC, partially "immunized" both men and women against later development of melanoma.
...
All this thoroughly explodes the claim that sun exposure causes malignant melanoma.
In the 19 years since publication of Beral’s carefully researched article in the Lancet, no one has refuted the finding.
But many ignore it and could make more money if the article and its information would simply go away.
Why do fluorescent lights cause melanoma? "Emissions from such light extend into the potentially carcinogenic range."
Dr Ott found that, specifically, the cathodes located at the ends of the light tubes emit X-rays and other electromagnetic pollution.
Plants living under the central portion of long fluorescent light tubes grow normally; but when placed close to the ends of the tubes, their growth is abnormal and stunted. Laboratory animals placed in a cage close to the ends of these light tubes become aggressive and cannibalistic.
Dr Ott also found that the light from fluorescent tubes, as well as TV sets and computer terminals, causes red blood cells to clump together after prolonged exposure. This reduces alertness, promotes a tired feeling and increases the risk of heart attack and stroke.
But when the ends of the light tubes are shielded with lead and traces of UV are added to the light, plants and animals under them grow and function normally.
And so wrapping the ends of fluorescent light tubes with lead tape, says Dr Ott, is fully as important as full-spectrum light itself.
Melanoma can also result from excessive exposure to sunlamps; their rays and those from bright halogen lights include some of the dangerous UVC.
If users of sunlamps consume a junk diet, their risk of melanoma will be increased.
Halogen lamps are also a serious fire hazard if they fall over or if inflammable material touches the extremely hot bulb.

Chlorination and Melanoma
Drinking and swimming in chlorinated water can also cause malignant melanoma.
Sodium hypochlorite, used in chlorination of water for swimming pools, is mutagenic in the Ames test and other mutagenicity tests.
Redheads and blonds are disproportionately melanoma-prone; their skin contains a relative excess of pheomelanins compared to darker people.
Franz H. Rampen and his associates in The Netherlands state that the worldwide pollution of rivers and oceans and the chlorination of swimming pool water have promoted an increase in melanoma.
Another major factor in the increase in reported incidence of melanoma has been physicians’ continually relaxing their standards for what constitutes melanoma.
Synthetic Hormones and Melanoma
What about oral contraceptives and hormone replacement therapy (HRT)?
Melanomas have increased sharply among women in the principal Pill-taking countries of Australia, America and in Europe.
In the Walnut Creek (California) study, all the women who developed melanomas under the age of 40 had used the Pill.
By 1981, the overall increased melanoma risk for Pill-users was statistically significant at three times.
The Pill also promotes development of heart attacks, in part by depleting body stores of vitamin B6.
Further, like breast cancer cells, those tumours have oestrogen receptors.
And so women on HRT are more likely to develop melanomas than non-users.

II. Ultraviolet Deprivation Health Effects
Certain effects of ultraviolet deprivation are equally remarkable and tie together with health benefits.
FS Light & Childhood Health
In 1973, radiation-shielded full-spectrum (FS) lights were installed in five classrooms in Sarasota, Florida.
And what happened? Several extremely hyperactive, learning-disabled children calmed down completely and learned to read.
Absenteeism dropped.
The children in four standard-lit rooms continued to misbehave (as tracked by concealed motion-detecting cameras); their learning disabilities and absenteeism were unabated.
And after a year, students in the full-spectrum classrooms had one-third less tooth decay than those taught under standard lighting.
Laboratory mice, which had been exposed all their waking hours to FS light, had zero tooth decay.
Similar findings were reported from California, Washington state and Alberta, Canada.
A classroom comparison in Vermont found that full-spectrum lighting strengthened immunity.
Why was there so much less tooth decay after exposure to full-spectrum light, including trace UV?
And why did immunity improve under FS lights? According to Dr Ott:
"Every nutritional substance and medicine has a specific wavelength absorption.
If those wavelengths are missing in the artificial light source a person is exposed to, then the nutritional or other hoped-for benefits of the substance will not be utilized."
UV functions as a nutrient and as a co-factor (a substance required for a bodily process to occur) in the utilization of other nutrients.
So the full-spectrum lights corrected the children’s deficiency of vitamin D3 (not the same as the toxic form of vitamin D added to milk),
now considered a pro-hormone.
This enabled more complete calcium absorption--and lowers the risk of osteoporosis and hip fractures in later life.
Recent research has found that nearly half the people of all age groups taking RDA-strength supplements have too little vitamin D.
When the body doesn’t have enough of it to absorb adequate calcium from food, it extracts calcium from bone.
FS light also strengthens immunity in other ways.
It helps protect against multiple sclerosis, heart attacks and conversion of HIV to AIDS, among other things.
