The relationship between vitamin D and your immune system

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.

  • Reflexology and Pain Management – Part 1

    Pain is a fact of life, it is a necessary part of being human.  Pain is a universal experience that serves the vital function of triggering avoidance. Pain is not a simple sensory experience, it can occur even in the absence of tissue damage. It involves emotional, social and cognitive beliefs. The four pillars of pain include

    1. Peripheral nervous system or the movement system
    2. Autonomic system, composing the sympathetic, parasympathetic, hormonal and visceral systems
    3. Central nervous system
    4. Psycho-emotional aspects, such as stress, anxiety, fear, social life and memory of pain.
    Physiological pain acts as a warning of actual or potential tissue damage and is usually transient.  It may be accompanied by an increase in heart rate, blood pressure and temperature.  Physiological pain of pathological origin results from tissue damage.  Tissue damage causes the release of neurotransmitters into the bloodstream creating inflammation, which can produce redness, swelling, and heat and further enhance the pain experience.  The area may also be sensitised, stimulating further neurochemical output and resulting in an ongoing cycle of pain - referred to as chronic pain. A growing evidence base for reflexology in pain management.  It is not yet fully understood how reflexology helps manage pain, although current opinion suggests it works on the neurological system through the release of endogenous opioids*. So if you are in pain, why not book a reflexology treatment.   * Sources Stephenson NLN and JA Dalton (2003).  Using Reflexology for pain management; a review, Journal of Holistic Nursing 21(2) pg 179 - 191 Mackereth P (2005) An explanation of therapeutic outcomes of reflexology and relaxation interventions for people with multiple sclerosis, University of Mancherster  

  • Natrual Ways to Reduce Anxiety – Part 1

    Anxiety is very comman and from time to time its perfectly natural.  However when it becomes excessive then its time to do something about it.  There are several types of anxiety

    • General anxiety disorder
    • Panic attacks or panic disorder
    • Phobias
    • Obsesive compulsive disorders
    Cognitive Behavioural therapy, a form of counscelling is on one of the most effective long term treatments for anxiety-related disorders. Over the next few blog articles I want to share some natural ways that may help. Passionflower (Passiflora Incarnata), a herb has been used for centuries as a mind calmer and mood boster.  There is strong evidence it is effective and in one study it was just as effective as the anti-anxiety drug, oxazepam for generalised anxiety.

  • So you thought you knew what causes hardening of arteries … think again

    The standard theory of heart disease states that fatty foods cause the arteries to "clog up" and narrow, which is a major feature of cardiovascular disease.  Researchers have discovered that a lack of sleep seem to have more to do with hardening of the arteries (atherosclerosis) than a fatty diet. Not getting enough sleep on a regular basis can cause a buildup of plaque in the arteries, which causes them to stiffen and eventually close. Researchers at Massachusetts General Hospital now think that hardening of arteries has more to do with a "neuro-immune axis" linking sleep to the cardiovascular system.  Sleep helps regulate the production of inflammatory cells and maintain healthy blood vessels, and so it would follow that lack of sleep has the reverse effect. The researchers demonstrated the effect on a group of laboratory mice.  Although the cholesteral levels of sleep deprived ice remained the same, they developed larger arterial plaques and had double the number of inflammatory cells known to contribute to hardening of arteries.
