Patrick Tims via NaturalHealth365 – According to a recent study done at the University of California – San Francisco, exposure to the sun can protect youngsters and young adults against multiple sclerosis (MS) and other autoimmune diseases. The scientists found that exposure to the sun’s UV rays increases vitamin D and might help prevent autoimmune diseases. Though parents have certainly been warned about subjecting their little ones to too much sun, the truth is the sun has its benefits. Not to mention that slathering on commercial sunscreens with potentially harmful chemicals poses a danger, now there is even more reason to let kids, tweens, teens, and adults enjoy the sun without excessive worry. Sunlight May Reduce Risk of MS, Research Suggests MS, short for multiple sclerosis, might be less likely to develop in individuals subjected to sunlight in considerable amounts at a relatively young age. The study referenced above indicates an association between heightened exposure to ultraviolet light and a reduction in the chances of developing MS. However, it must also be noted that significant exposure to sunlight without protection has the potential to heighten the chances of skin cancer. The study pertained to slightly more than 330 individuals between the ages of 3 and 22. The study participants had MS for an average period of seven months. As revealed in the web-based issue of Neurology, the result of the study was officially made available to the public in December of 2021. Responses to study inquiries showed that about 20% spent less than half an hour outdoors one summer ago. Only 6% of those without MS spent less than half an hour outside during the summer. The study showed that those who averaged half an hour to a full hour outside had a 52% less risk for developing MS when compared to individuals who spent less than half an hour outdoors on summer days. Sun Exposure Is More Important Than Most Think The key takeaway from the study is that the sun has meaningful benefits. Exposure to sunlight enhances vitamin levels, stimulates the skin’s immune cells that help protect against MS, and possibly even alters the functionality of immune cells to help guard against autoimmune diseases and maintain optimum health. It is interesting to note that some MS patients show symptoms during their childhood though the disease usually doesn’t fully manifest until the adult years of 20 to 50. Here Is Why Geography Is Important in the Context of MS The researchers also pointed out that those involved in the study who live in Florida were more than 20% less likely to develop MS than those living in New York state. The reduced chance of developing MS is likely the result of the heightened sunlight intensity in Florida. The study also revealed that exposure to the sun provides benefits dependent on the dose. In other words, the more time that one spends exposed to the sun, the lower the risk is for MS and other autoimmune disorders. It is also interesting to note that the study reveals exposure to the sun’s rays in the initial year of life also played an important role in protecting against the development of MS. One final warning, if you’re concerned about MS, do everything you can to avoid the consumption of artificial sweeteners. Click here for more information about the dangers of artificial sweeteners.

Cashew Shell Compound Appears to Mend Damaged Nerves

Vanderbilt University Medical Center via EurekAlert – In laboratory experiments, a chemical compound found in the shell of the cashew nut promotes the repair of myelin, a team from Vanderbilt University Medical Center reports today in the Proceedings of the National Academy of Sciences. Myelin is a protective sheath surrounding nerves. Damage to this covering — demyelination — is a hallmark of multiple sclerosis and related diseases of the central nervous system. “We see this as an exciting finding, suggesting a new avenue in the search for therapies to correct the ravages of MS and other demyelinating diseases,” said the paper’s senior author, Subramaniam Sriram, MBBS, William C. Weaver III Professor of Neurology and chief of the Division of Neuroimmunology. Previous work led by Sriram showed that a protein called interleukin 33, or IL-33, induced myelin formation. IL-33 is, among other things, an immune response regulator, and multiple sclerosis is an autoimmune disorder. The cashew shell compound is called anacardic acid. Sriram and team grew interested in it because it’s known to inhibit an enzyme involved in gene expression called histone acetyltransferase, or HAT, and the team had discovered that whatever inhibits HAT induces production of IL-33. The report includes a range of new findings that point to potential therapeutic use of anacardic acid for demyelinating diseases: In vitro, the addition of the compound to rat cells most responsible for myelination — oligodendrocyte precursor cells, or OPCs — spurred induction of IL-33 and rapidly increased the expression of myelin genes and proteins, including dose-dependent increases in myelin basic protein; In two animal models of demyelination, treatment with the compound increased the relative presence of IL-33-expressing OPCs and led to reduced paralysis; In an animal model of demyelination treated with the compound, dissection and electron microscopy showed dose-dependent increases in myelination. “These are striking results that clearly urge further study of anarcardic acid for demyelinating diseases,” Sriram said.
