Asthma significantly helped by vitamin D through sunshine

Asthma significantly helped by vitamin D through sunshine

This latest study has found that low levels of vitamin D (made by the body through direct exposure to sunlight on bare skin), was linked to a worsening of asthmatic symptoms.

“We know people with high levels of vitamin D are better able to control their asthma - that connection is quite striking.  A culture of covering up in the sun and using sun cream may have increased asthma rates…  Vitamin D could one day be used not only to treat people with steroid resistant asthma but also to reduce the doses of steroids in other asthma patients, reducing the risk of harmful side effects.  The results are so positive that we are testing this in a clinical trial in steroid resistant asthma patients to further research the possibilities of vitamin D as a potential treatment”
Professor Catherine Hawrylowicz from the Medical Research Council & Asthma UK Centre in Allergic Mechanisms of Asthma at King’s.

“Many people with asthma have concerns about the side effects of their medicines so if vitamin D is shown to reduce the amount of medicines required, this would have an enormous impact on people’s quality of life”
Malayka Rahman, Asthma UK.

  • Vitamin D was found to calm an over-active part of the immune system, a natural chemical in the body called interleukin-17 (IL-17A), that aggravates symptoms in asthma patients and reduces responsiveness to steroids 
  • Patients with steroid resistant asthma expressed the highest levels of IL-17A

Study on 28 patients by researchers at King’s College in London, as published in the Journal of Allergy and Clinical Immunology, May 2013.  As reported by BBC News on May 20, 2013.  As reported by The Daily Mail on 19 May 2013.
