 The researchers recommended that all MS patients should get adequate sunlight exposure and do specific strengthening exercises for their hip and back muscles to prevent debility and osteoporosis. In another clinical study, the blood levels of vitamin D were found to be lower during relapses. This was thought to play a role in regulation of clinical disease activity. One of our MS patients has been seeing us for over 10 years. His condition was stable, but he was still not well. We added vitamin D-3 to his orthomolecular program, 5000 IU twice daily. |

 It is essentially created and then destroyed, so the net effect is that your body will never, on its own, create too much vitamin D from sunlight exposure. The only way to overdose on vitamin D is to do it through supplementation or the mass consumption of substances like fish oils. Given the fact that people don't eat very much fish oil, it's very difficult to overdose unless you're actually chugging processed fish oil by the cupful. |

 The vitamin D present in food and that formed by sunlight exposure actually has little or no biological activity. In order to become effective, it must first be converted by the livet and kidney into one of its active byproducts (1 alpha-hydroxyvitamin D or 1,25-dihydroxyvitamin D). These are the forms of vitamin D that have been used in clinical studies of patients suffering from psoriasis. In some reports, the vitamin was applied to the skin, and in others it was taken orally. The results obtained with this treatment have been consistently positive, and in some cases have been dramatic. |

Yet each summer the public is bombarded with warnings about skin cancer and advised to use sunscreen lotion while there is no equal public awareness created for the massive public deficiency of vitamin D. More than 40% of the American population is at higher risk for cancer due to shortages of vitamin D.
The shocking revelation came in 2005 from researchers at the Melanoma and Skin Cancer Research Institute, Sydney Cancer Centre, Sydney, Australia. Both UV-A and UV-B sun rays promote skin cancer. |

 However, by adding vitamin D to the equation through sunlight (remember, your skin generates vitamin D in response to sunlight exposure), senior citizens can start assimilating calcium and rebuilding their bones.
This is information that doesn't get told to senior citizens, and modern doctors don't even understand it. They think that you treat osteoporosis with drugs, which is ridiculous. The only thing you need in order to treat osteoporosis is sunlight, calcium and a little bit of physical exercise. You will rebuild bone mineral density very rapidly on that kind of program. |

 Since sunlight exposure causes vitamin D production in the human body, individuals who intentionally expose themselves to sunlight will now be arrested and have their blood confiscated by federal health authorities. All citizens are advised to coat themselves with sunscreen every time they go out in the sun and avoid sun exposure until further notice.
Individuals caught seeking sunlight may be charged with not only possession, but trafficking of the vitamin D drug. DEA agents have been alerted and will be called in to arrest sunbathers. |

| Even today, the American Cancer Society still runs silly public service ads that try to scare people away from sunlight exposure. Click here to see an example ACS ad.
That is why I think we need such technology so desperately. If I had the research money, I would try to research and produce such a device. I'm sure there are better-qualified individuals and companies out there who have expertise in this area, and I hope that this kind of information encourages them to move forward with the knowledge that, if such a device existed, I would be one of its strongest proponents.

| As long as people believe that sunlight is dangerous, the sunscreen makers will sell more sunscreen products, but the minute the population realizes that sensible sunlight exposure is not dangerous and that it is, in fact, crucial for long-term health, sunscreen sales will plummet.
This is exactly why sunscreen manufacturers would be outspoken critics of portable consumer vitamin D sensors. I predict this will happen in the future. Dermatologists, who are closely aligned with sunscreen manufacturers, may even join the outcry against the vitamin D sensor. |

 John's wort, avoid prolonged sunlight exposure. Doses of 1800 mg or more a day of St. John's wort extract can be unsafe because of the risk of severe phototoxic skin reactions. Concomitant use with oral contraceptives may decrease steroid concentrations, resulting in breakthrough bleeding and irregular menstrual bleeding. Effectiveness of antiretroviral drugs such as nevirapine (Viramune), delavirdine (Rescriptor), and efavirenz (Sustiva) may be reduced.

 In addition, people who receive adequate sunlight exposure do not need as much vitamin D in their diet as do people who receive minimal sunlight exposure.
Vitamin D increases both calcium (p. 277) and phosphorus absorption. Vitamin D has also been reported to increase absorption of aluminum. Increased blood levels of calcium (which can be a marker for vitamin D status) have been linked to heart disease (p. 32).7 Some,8 but not all/ research suggests that vitamin D may slightly raise blood levels of cholesterol (p. 79) in humans.

| Many factors influence vision and cataract development such as age, nutrition, heredity, medications, toxins, health habits, sunlight exposure, and head trauma. Cataracts can also be caused by high blood pressure, kidney disease, diabetes, ot direct trauma to the eye.
The good news is that a lot of published teseatch exists showing that the cataract progression can be slowed or prevented by the use of natural therapies and minor lifestyle changes. |
| Thus, experts recommend at least 400 IU of vitamin D a day; if the individual is elderly and not participating in outdoor activities (and sunlight exposure), 800 IU a day is recommended (Thomas et al. 2000). |

 Vitamin D may have the ability to inhibit the proliferative activity of hormones, such as estrogen in breast cancer, and has been shown to suppress breast and prostate cancer growth. sunlight exposure, which leads to an increased level of vitamin D, correlates with a reduced risk of breast cancer. I usually recommend small amounts of vitamin D (400 to 1,000 IU) for those people without sunlight exposure, especially during the winter. I also occasionally recommend cod liver oil during the winter months as a source of vitamin D and omega-3 fatty acids. |

 Seasonal affective disorder is due to insufficient sunlight exposure. Expose yourself to one or two hours of very bright full-spectrum electric light each day, preferably in the morning; if possible, be outside in sunlight and without sunglasses. In addition, use yellow or orange color therapy for all forms of depression; also look into the light source (see step 17). Wear bright-colored clothing. Use deep-breathing exercises; dance to lively music and shake the whole body for a minute during fast breathing. |

 The most important source of vitamin D is the skin's synthesis of the vitamin from sunlight exposure. People who live far from the equator (and therefore get less sunlight), who use sunblocks, or who have heavy skin pigmentation (African Americans have high melanin concentrations, which limit vitamin D synthesis), all may be at risk for low levels of vitamin D. Sunblocks can cut vitamin D production by about 95 percent. I am not recommending discontinuing using sunscreen, but this is a good reason to increase your dietary sources of vitamin D. |

 Townsend Letter for Doctors strongly correlates sunlight exposure with less incidence of breast,'7 colon,18 and other cancers.19 Malignant melanoma (the most feared "sun-induced" skin cancer) has been related specifically to "blister and peel" sunburning, especially if this type of sunburning occurred before the age of twenty.20 You may be surprised to know that melanoma is less common in those who work outdoors than in those who work indoors.21 Regular and nonburning exposure to the sun, Ainsleigh concludes, is a good thing— should be sought a few hours, perhaps three times, weekly. |

 Shiitake is an efficient source for this nutrient, containing between 873 and 4,381 IU/100 g of dry mushroom weight (Kobayashi, 1988; Kiribunchi, 1990; Takamura et al, 1991; Takeuchi et al, 1991). sunlight exposure also increases the free amino acid content which is about 2,180 mg% in the dry fruiting bodies, and it makes them sweeter and less bitter (Kiribuchi, 1991). |

 Doll and Peto have vigorously espoused the lifestyle or "blame-the-victim" theory of cancer causation, with its virtually exclusionary emphasis on the role of smoking, fatty diet, and sunlight exposure. Ames embraces the lifestyle theory and expands it with the creative claim for a major role for "natural carcinogens" in food.

 Since it rarely occurs with adequate sunlight exposure, it did not become a major public health concern until the industrial revolution, when smog-filled crowded cities arose in northern Europe and America, and people (including small children) spent extended periods indoors. This led to a 270-year search for a cure, and eventual isolation of vitamin D in the early 1900s. Supplementation of dairy products with vitamin D since the 1930s has virtually eliminated the problem in children.58

 It is well known that ultraviolet light promotes cataract formation, and that cataracts are more common in countries with strong sunlight exposure. In nutritional studies, subjects who did not take vitamin C (300 to 600 mg/day) had four times higher risk of developing cataracts.
Vitamin C is a relatively nontoxic vitamin. There are few toxic side effects, even when taken in extreme doses. One side effect is diarrhea. Another concern is that vitamin C is partially converted into oxalates, which are major components of kidney stones. |

 There is considerable scientific evidence that this supplement can act as an antioxidant and energizer that can prevent many of the detrimental effects of sunlight exposure.
LM Take 1,000 milligrams of chondroitin sulfate daily for premature wrinkling of the skin (wrinkles that appear before age thirty-five). Chondroitin stimulates the growth of skin cells and accelerates metabolic processes that help the skin retain moisture.
LM Drink eight glasses of water daily. Adequate hydration helps maintain skin tone. |
| J Whenever possible, get twenty to thirty minutes of sunlight exposure every day (but be sure to avoid heat stress). Sunlight helps the skin manufacture vitamin D, which halts the growth of prostate cancer cells. Vitamin D is especially important in controlling prostate cancers that are not stimulated by testostrone. When it is not possible to get sun, take from 200 to a maximum of 1,000 international units of supplemental vitamin D daily.
LI Eat five to seven weekly servings of foods rich in vitamin A; this includes green leafy vegetables, and orange and yellow fruits and vegetables. |
| Sunlight exposure accelerates the rate at which the body breaks down this important medication.
LJ Avoid iron and choline supplements. These substances cause the breakdown of dopamine in the brain. Also avoid iron-rich foods, such as liver and organ meats.
LJ Avoid aluminum and especially manganese compounds, which can greatly accelerate the progression of this disease. Aluminum can leach from aluminum cookware used to prepare acidic foods and is found in some antacids and deodorants. Manganese is included in some multivitamin/ mineral preparations. |
| Ll Whenever possible, get twenty to thirty minutes of sunlight exposure every day (but be sure to avoid heat stress). Sunlight helps the skin manufacture vitamin D, which helps prevent the spread of kidney cancer to the bones. It also may slow the growth of primary tumors in the kidney.
CONSIDERATIONS
Ll Immunotherapy is the use of agents that stimulate the immune system. Interferon-alpha slows the growth of cancer cells, and alters their surfaces so that immune-system cells called macrophages can recognize and destroy them. |

| In case of boils, furuncles, carbuncles, sunlight exposure to the extent of producing a burn may abort or cure any of these infections. Cover the rest of the body, exposing only the affected tissues. Poison ivy and poison oak are benefited by erythema doses. Spreading is usually checked. Shingles are greatly helped by erythema doses. Sunlight is specific for lupus (TB.) of the skin, but treatment should not be undertaken without the supervision of a physician trained in the proper technique. |

 Low food intake is the environmental stimulus that provokes these unique adaptations, just as sunlight exposure provokes the adaptive pigmentation of skin. If you want to change the way your body is adapting, you have to start by understanding what environmental stimulus provokes the adaptive responses. And in order to eliminate adaptive responses, you must change the stimulus that provokes them.
For example, a person who wants to stop the adaptive tanning response would logically avoid exposure to sunlight. |
