UVB exposure benefits by Marc Sorenson, EdD. Sunlight Institute…
UVB is a spectrum of sunlight that is responsible for stimulation of vitamin D production in the skin. It also has many other effects, including the suppression of inflammation in the skin, and thus has been used to very successfully treat skin diseases such as psoriasis and eczema.   
Since inflammation is also necessary to produce the condition of atherosclerosis (arterial plugging or occlusion) in arteries, it would be interesting to know whether UVB light might also have the same anti-inflammatory effects in those arteries. If so, the UVB effect could inhibit or eliminate atherosclerosis, and by so doing provide an entirely new treatment for heart disease and other vascular events such as stroke and intermittent claudication.
The idea that UVB could prevent atherosclerosis by reducing inflammation in arteries was recently studied by Japanese researchers.  Using a mouse model, they demonstrated that UVB light irradiation, once weekly for 14 weeks, leads to an increase in the action of T-regulatory cells that inhibit inflammation. In addition, UVB exposure also reduced the production of another type of T-cell that is pro-inflammatory, and thereby proatherogenic (leading to the production of atherosclerosis). These two effects of UVB light reduce the development and progression of atherosclerosis. Or stated differently, the research shows that sun exposure is critically-important therapy to reduce and prevent heart and other vascular diseases.
Protect your heart by being sure to obtain sufficient non-burning UVB light from sun exposure or other sources such as the UVB lamps used by the researchers. It is important to note that neither skin cancer nor skin inflammation were observed following UVB exposure.
This is another breakthrough study that emphasizes the necessity of sun exposure for human health.

Although I occasionally try to balance the messages about tanning beds, this blog is meant neither to discourage nor promote their use. The readers should make up their minds after weighing the evidence. In a recent blog, I mentioned some positive messages about tanning-bed use, which included the following: Note: all references for the following list are found in the blog under footnote 1.
- Tanning-bed use is associated with a reduced risk of clots.
- Tanning-bed use is associated with increased vitamin D levels.
- Tanning-bed use is associated with stronger bones
- Tanning-bed use can cure psoriasis and eczema and tanning beds are often recommended by dermatologists.
- Tanning-bed use more than three times yearly is associated with a 40-50% reduced risk of endometrial cancer.
- Tanning-bed use is associated to lower breast-cancer risk.
After I posted the above information, a friend from Canada reminded me of research by Dr. Pelle Lindqvist and his colleagues, which demonstrated that both sun exposure and tanning-bed exposure reduced the risk of death during a 20-year study. Women who used tanning beds were 23% less likely to die of any cause than women who did not use them.
In addition, I remembered an older study that showed that tanning beds were able to take winter vitamin D levels up to summer levels in a period of five weeks.
So, along with the bad rap tanning beds are receiving, there is some good news. Who wouldn’t want to live longer in better health? Still, as with all decisions, weigh the evidence and then decide.

Drs. Asta Juzeniene and Johan Moan wrote a paper in 2012 that beautifully summarizes the effects of sunlight beyond the production of vitamin D. Here are the highlights of their paper, as stated in the abstract. They discuss the separate affects of Ultraviolet B light (UVB) and ultraviolet A light (UVA), which are, of course, components of sunlight.
- UVB induces cosmetic tanning (immediate pigment darkening, persistent pigment darkening and delayed tanning).
- UVB-induced, delayed tanning acts as a sunscreen.
- Several human skin diseases, like psoriasis, vitiligo, atopic dermatitis and localized scleroderma, can be treated with sunlight or artificial UV radiation (phototherapy).
- UV exposure can suppresses multiple sclerosis independently of vitamin D synthesis.
- UVA generates nitric oxide (NO), which may reduce blood pressure and generally improve cardiovascular health.
- UVA induced NO may also have antimicrobial effects.
- UVA induced NO may act as a neurotransmitter.
- UV exposure may improve mood through the release of endorphin.
It wasn’t mentioned in the paper, but we now know that sunlight also helps generate serotonin in the brain, which improves mood, and outside the body it is a potent disinfectant (see my recent blogs on those subjects). So those who claim that sunlight is harmful in any amount, must be living on a different planet. Embrace the Sun, but never burn.

Some common-sense scientists understand that UV light is nearly 100% effective for many dermatological conditions, and that tanning beds are very convenient sources of UV for patients who cannot otherwise afford the rigorous travel and time commitments necessary to visit the dermatologist.[i] Their investigation involved an arduous search for scientific papers that reported on tanning beds and their salutary affects on different skin diseases.
The searches showed convincingly that tanning beds were a valid use for psoriasis, but also indicated tanning beds could be useful “as a treatment option for atopic dermatitis, mycosis fungoides, acne, scleroderma, vitiligo, and pruritus, as well as other UV sensitive dermatoses.”
The conclusion they reached was amazing, considering negative reports that are regularly touted by the press. They stated: “Unsupervised sun exposure is a standard recommendation for some patients to obtain phototherapy. Selected use of commercial tanning beds in the treatment of dermatologic conditions may be another useful and effective treatment for those patients with an inability to access office-based or home-based phototherapy.”[Italics mine]
One of the dermatologists who recommends unsupervised sun exposure as stated above is Dr. Julie Moore of Gottlieb Memorial Hospital. She says that sunlight is one of the best ways to treat psoriasis, so she recommends that her patients “sit out on the deck and give their affected areas a good sun bath.[ii]”
Hallelujah! Common sense is beginning to penetrate the dermatology profession, as more dermatologists are climbing on the sunlight bandwagon each year. Now go and spend some safe, non-burning time in the sunlight!

By: Marc Sorenson, EdD Sunlight Institute–
An American Dermatologist says that sunlight exposure can stop psoriasis, as reported in Science Daily. Julie Moore, M.D. a dermatologist at Gottlieb Memorial Hospital, part of Loyola University Health System, makes the following statement: “30 minutes is adequate to improve the skin; you do not need to sit out for hours.”
It has been known for years that sunlight or UVB light from sunlamps has curative effects on psoriasis, and dermatologists have used sunlamps in their medical practices for years, while advocating nearly complete sun avoidance. The stunning part about the article is the fact that an American dermatologist is making the statement, because the American Academy of Dermatology (ADA) has vehemently opposed sunlight exposure for decades, and a past president has even suggested that we should all move underground to avoid the hazards of sunlight. British Dermatologists have been much more willing to suggest that a few minutes of sunlight around midday can improve health and optimize vitamin D levels, but too many American derms have continued to chant the mantra of the ADA.
