Asthma is one of the most common chronic diseases worldwide, and the number of people affected by this as yet incurable disease keeps increasing steadily.  Since there is no known cure for asthma, researchers continue trying to isolate factors that make the symptoms less severe and life threatening.  Several studies have tried to link severe asthma symptoms with low levels of vitamin D in patients’ blood.  Lung function tests were administered to a random group of asthma patients.  The testing showed that asthmatics with higher blood levels of vitamin D had better lung function than those participants with low levels of vitamin D.  Further research is needed to understand what role vitamin D can play in asthma treatment.

P.S.   Low levels of vitamin D in the blood may be associated with less sun exposure during the winter months and/or use of sunscreen protection during the summer months.
