Inflammatory bowel diseases (IBD) are known as Crohn’s disease (CD) and Ulcerative Colitis (UC). UC is a chronic inflammatory condition characterized by relapsing and remitting episodes of inflammation limited to the mucosal layer of the colon. Crohn’s however, can involve any part of the gastrointestinal tract from the mouth to the anus, but most commonly affects the small intestine or the colon, or both.
New Italian Research
Research from Italy, published in December, 2017, shows that inadequate sun exposure is associated closely with IBD. The researchers demonstrated that “Patients with IBD are significantly less exposed to sunlight then controls in our Mediterranean Country, often to an extent that may impair Vitamin D activation.” Consequently, they suggest that increased sun exposure may prove beneficial to patients.
Furthermore, in a 12-year investigation of hundreds of thousands of IBD patients, the following was found: Hospitalizations and prolonged hospitalizations for both UC and CD were higher among those who had low sun exposure, compared to those with very high sun exposure. In addition, the same relationship was shown between sun exposure, bowel surgeries and deaths: more surgeries were needed for those IBD patients who experienced the lowest sun exposure compared to those who had the highest sun exposure, and more deaths occurred among those with low exposure.
Does sun exposure help other diseases?
Furthermore, an interesting side note to the aforementioned investigation was the large number of non-IBD patients analyzed for sun exposure levels. Most noteworthy was the finding that the same relationship existed as with the IBD patients—low sun exposure was associated with prolonged hospitalizations and more deaths when compared with high exposure. Therefore, sun exposure saves lives, whether by decreasing IBD or preventing the myriad additional diseases that we have previously discussed.
In conclusion, if you have a painful feeling deep in your gut, take action: First of all, get a diagnosis. But do it while simultaneously increasing your safe, non-burning sun exposure. It may be just what the doctor ordered!
