Can sun exposure reduce rheumatoid arthritis (RA)?
RA is a terrible, crippling disease, which causes chronic inflammation of the joints, the tissue around the joints, and certain organs in the body. Like most diseases, it is one to be avoided and prevented when possible, and sun exposure may indeed help. At our former health resort in Southern Utah, we observed that many people were able to reduce the swelling and inflammation of this disease through adherence to a mostly plant-based nutrition program, or so we thought. Sun exposure in our very sunlit climate may have also played a critically-important part. One of our attendees was a former writer and piano player whose fingers had lost their ability to use the keyboards on either the computer or the piano. In less than two weeks she had gained sufficient range of motion in her hands to resume her two important activities. In addition, the swelling of her knuckles was profoundly reduced. And whereas the nutrition we used was doubtlessly responsible for much of her success, sun exposure was likely responsible for the remainder.
One paper demonstrated that at high latitudes, where sun exposure is considerably less available, the rate of RA is much higher than at lower latitudes. RA is also more severe in winter, a time of less sun exposure. In another report from researchers in Ireland (a northern country with little sun exposure due to overcast conditions), it was shown that 70% of patients had low vitamin D levels and that 26% were severely deficient. And in an investigation using data from the nurses health study, those women who were in the highest versus the lowest category of UVB (ultraviolet light exposure from sun or other sources), had a 21% decreased RA risk.
RA is an autoimmune rheumatic disease (ARD), and seasonal vitamin D declines may trigger flares in (ARD). Such declines, of course, are a result of decreasing sun exposure in the colder seasons.
Arthritic joints carry another devastating side effect. Hip replacement surgery is often prescribed for arthritic conditions, and those people who go through total-hip-replacement procedures are 4.7 times as likely to have an ischemic stroke, and 4.4 times as likely to have a hemorrhagic stroke in the first two weeks post surgery. Those stroke risks remain elevated for 6-12 weeks.
Eat correctly and safely soak up the sun. It’s a better option than hip replacement and potential stroke!

Sun exposure and health By Marc Sorenson, EdD, Sunlight Institute…
New research shows that sunlight boosts the effectiveness of T-cells, an integral part of the immune system. T-cells are a type of lymphocyte that recognizes and binds to foreign invaders, thereby rendering them harmless. This is an important new finding, which demonstrates another beneficial effect of sun—one that has no relationship to vitamin D.
The key player in this action is the blue-light spectrum of sunlight that stimulates hydrogen peroxide production. The hydrogen peroxide (HP) causes T-cells to move to the site of infection, and it (HP) is also involved in the killing of noxious bacteria. Dr. Gerard Ahern, one of the primary investigators, stated it in this way: “T cells, whether they are helper or killer, need to move to do their work, which is to get to the site of an infection and orchestrate a response. This study shows that sunlight directly activates key immune cells by increasing their movement.”
Also interesting is the fact that the skin has a large share of the total T-cells in humans, about twice the number circulating in the blood. Think about this magnificent body of ours! It is programmed to immediately respond to any invasions that may occur in the skin, and sun exposure, if we take full advantage of it, immediately accelerates the process. Then, when the t-cells are activated by the blue light, they can move rapidly to other body areas where they can be utilized.
Sun exposure has also been found to have an exceptionally important and positive effect on autoimmune diseases such as lupus, MS, rheumatoid arthritis and others, many of which have been found to associate with low solar radiation and vitamin D. In this case, a different type of T-cell, called a regulatory T-cell, attacks the body’s own tissue, mistaking it for a foreign invader, and causes severe damage. The mechanism of autoimmune disease prevention by sunlight may be the suppression of regulatory T cells, in a manner that impedes the immune system’s attacks on its own tissues. 
Sunlight is one of God’s (or Nature’s) greatest miracles. Be sure to receive your full contingent of wonderful, non-burning sun.

We have covered the affect to sunlight and diabetes several times, but most of the posts focused on type-2, which is the more common of the two and is becoming a pandemic. Type-2 results when the body produces plenty of insulin, but becomes resistant to its effects, leaving both blood sugar and insulin elevated. Type-1 diabetes is a totally different disease, although high blood sugar is still the result. Both of these diseases, however, correlate to low sunlight exposure. Type-2 is usually caused by atrocious eating habits and obesity, but sunlight deficiency associates with its risk. Either way, these diseases can lead to blindness, erectile dysfunction, neuropathy, heart disease, hypertension, obesity, kidney disease, amputation of limbs and death. The side-effects of diabetes are usually much more harmful than the diseases themselves.
Type-1 is a disease that afflicts many babies and young people and is sometimes known as “juvenile diabetes.” It is an autoimmune disease, such as multiple sclerosis or rheumatoid arthritis, and is totally different in its cause from type-2, which is caused by atrocious eating habits and obesity. Type one usually happens when the body’s own immune system attacks the pancreas, rendering it useless insofar as insulin production is concerned. The consumption of cow’s milk correlates very closely to contracting the disease by babies and very young children.
Here are some facts regarding the relationship between sunlight and Type-1. Australian research shows that the incidence of type-1 diabetes correlates closely with latitude; the southernmost part of the country, which has far less availability of sunlight, has about three times the incidence as the northernmost.[i] And in Newfoundland, Canada, an extremely strong inverse correlation exists between sunlight exposure and incidence.[ii] [iii] Similar results have been reported by Dr. Mohr and colleagues, who analyzed the correlation between type-one diabetes and sunlight exposure in 51 regions worldwide and drew the following conclusion: “An association was found between low UVB irradiance [sunlight exposure] and high incidence rates of type 1 childhood diabetes after controlling for per-capita health expenditure. Incidence rates of type 1 diabetes approached zero in regions worldwide with high UVB irradiance, adding new support to the concept of a role of vitamin D in reducing the risk of the disease.”[iv]
The latest study on type-1 and sunlight comes from Denmark, where researchers assessed the association between exposure to sunshine during gestation (pregnancy) and the risk of type 1 diabetes in Danish children at the age of 15 years.[v] The results were that more sunshine during the third gestational trimester was associated with a 40% reduced risk of contracting the disease at age 15.
Sunlight is so important for nearly every aspect of health. Be sure to take advantage of it, as it may be waiting right outside and beckoning you.
