Reiki – Mechanisms of Healing – Part 2

In the 1980's researchers made the first connection between vitamin D deficiency and some cancers in when they noted populations at higher latitudes (with less available sunlight) were more likely to be deficient in vitamin D, which is produced by the body through exposure to sunshine, and experience higher rates of colon cancer. Subsequent studies by tfound vitamin D links to other cancers, such as breast, lung and bladder. In a recent study, scientists reported that when women upped their vitamin D dosage, they were nearly one-third more likely to survive breast cancer, particularly for premenopausal women. The mechanism is vitamin D's ability to stop the reproduction of cancer cells.  Researchers examined 1,666 women with breast cancer and found that the more 25-hydroxyvitamin D (250HD, a blood biomarker for vitamin D) they had, the better their chances of survival.   It should be noted that this research does not mean that low levels of vitamin D cause breast cancer nor should women with breast cancer flock to the nearest beach to sunbath.  Having said that researchers did comment that extra vitamin D can't hurt. Another important review which came out in 2016 linking low levels of vitamin D and aggressive prostate cancer. Researchers from Northwestern Medicine disclosing that: "Deficient vitamin D blood levels in men can predict aggressive prostate cancer identified at the time of surgery. The finding is important because it can offer guidance to men and their doctors who may be considering active surveillance, in which they monitor the cancer rather than remove the prostate." One of the crucial things to note is that low vitamin D levels were found via blood tests before any sign of prostate cancer showed up, so checking vitamin D levels beforehand could be life-saving, and a much better alternative to begin taking it a problem is discovered. Researchers at University of California, San Diego School of Medicine report that higher levels of vitamin D -- specifically serum 25-hydroxyvitamin D -- are associated with a correspondingly reduced risk of cancer. The findings published in PLOS ONE  in 2016 found that raising your vitamin D levels (if they are low) can slash your risk of invasive cancers excluding skin cancer by 67%! References

In part 1, I looked at the impact of sitting on your muscles, but what happens in the rest of your body? Leg Disorders We are all familiar with the risk of deep vein thrombosis (DVT) if we take long flights.  This is because sitting for long periods of time slows blood circulation, which causes fluid to pool in legs.  This creates problems ranging from swollen ankles, varicose beings to dangerous blood clots. Soft Bones Osteoporosis is a disease marked by reduced bone strength leading to an increased risk of fractures, or broken bones. Bone strength has two main features: bone mass (amount of bone) and bone quality.  Osteoporosis is often called a “silent disease” because it usually progresses without any symptoms until a fracture occurs or one or more vertebrae (bones in the spine) collapse.   Weight-bearing activities such as walking and running stimulate hip and lower-body bones to grow thicker, denser and stronger.  Medical researchers partially attribute the recent surge in cases of osteoporosis to lack of activity.

• diabetes
• gallstones
• hypertension
• heart disease
• stroke

We all struggle to get our heads around things from time to time.  For me I find it hard to imagine living with Fibromyalgia, the constant pain, which moves around the body and the tiredness.  In addition to the physical symptoms there is the additional mental strain of living with a chronic condition that is has no visible signs and can change from day to day. A pilot study recruited 22 women who had been diagnosed with Fibromyalgia to participate in a 75 minute yoga class twice weekly for eight weeks.  Questionnaires were used to track pain, anxiety and depression they were completed pre, mid and post intervention.  In addition salivary cortisol samples were taken three times a day pre and post intervention. The results indicate that a "yoga intervention" may

• Reduce pain
• Reduce catastrophising
• Increase acceptance
• Increase mindfulness
• Alter total cortisol levels
