The Impact of Sitting All Day – Part 5

Previously I discussed how dehydration & lack of sodium or potassium may cause muscle cramps.  I now want to explore other nutritional factors. Calcium Calcium plays an essential role in muscle contractions.  Some active people report their problem with cramping disappears when they boost their calcium intake.  This anecdotal evidence is disputed by scientists who state that when dietary deficiencies of of calcium occur, calcium is released from the bones to provide what the body needs for proper muscle contraction.  If you are plagued by muscle cramps, it may be worth trying to increase your intake of dairy or other calcium rich foods to see if it helps. Magnesium Just as muscles need calcium to contract they need magnesium to relax. Roffe et al demonstrated that magnesium helps reduce leg cramps that occur in the middle of the night.

Obviously I am a firm believer of massage in the workplace, so I will start by acknowledging my bias on the topic.  What people may not know is that during the many years working in IT, I suffered from a verity of neck and shoulder issues.  This lead me to go to see a GP, chiropractor, osteopath and masseur.  While they all helped, what was most beneficial to me was regular seated acupressure neck & shoulder massage which helped me nip the tension and the problems in the bud. We all know getting a massage feels great. Once your massages starts, the nerve cells in your skin send messages to your brain to release feel-good endorphins .  As a result stress hormones cortisol and adrenaline begin to decrease and the other all effect is to boost your mood and give you a natural high.  On a physical level the tension and tightness in the muscles begin to release. This means your awareness shifts so your mind and body can function better.  Researches find your mind gets de-cluttered helping you to think more clearly, improve your alertness which leads to improve performance. So why not book a massage see>> http://vitalitytherapy.co.uk/booking

A growing body of scientific evidence shows that vitamin D plays a crucial role in disease prevention and maintaining optimal health.  You have about 30,000 genes in your body and vitamin D affects nearly 3,000.  This is in addition to all the vitamin D receptors through out your body. Inflammation is the body's attempt at self-protection; the aim being to remove harmful stimuli, including damaged cells, irritants, or pathogens. While inflammation is a vital part of the body's immune response, it can also be problematic and plays a role in some chronic diseases e.g asthma, arthritis. Researchers investigated specific signalling events that vitamin D suppresses in order to inhibit inflammation.  Research published in The Journal of Immunology called it the "inflammatory cascade"; low vitamin D levels failed to inhibit the cascade while adequate levels did the job.  Researchers concluded that patients with chronic inflammatory diseases who are also vitamin D deficient may benefit from supplementation. Researchers in Turkey, reported in the international Journal of Rheumatic Diseases that chronic widespread musculoskeletal pain is improved with vitamin D.  Fibromyalgia sufferers and other patients with chronic widespread musculoskeletal pain were given 50,000 iu/week oral vitamin D3 for three months.  Afterwards scientists discovered decreases in pain, fatigue upon awaking, lack of energy, tender points and depression.  Significantly there were 30 Fibromyalgia patients at the beginning of the study and only 20 at the end! Next week I want to look at the relationship between low vitamin D levels and common ailments. References Zhang Y, et al. (2012).
