People with asthma are always cautioned from going out fearing exacerbation of symptoms. However, it may be a good idea to go for a walk in the park and catch some sunshine. Researchers from Tel Aviv University suggest that measuring and boosting Vitamin D levels may help manage asthma attacks.
Earlier studies have focussed on the link between vitamin D and asthma only in the paediatric population. The current study analysed the medical records of nearly four million young adult members of Israel’s Clalit Health Services between 2008 and 2012. The researchers also considered the key predictors of asthma such as obesity, smoking, and other chronic diseases. The results of the study are published in the journal Allergy.
The researchers found that out of the 21,000 asthma patients studied, those patients with Vitamin D deficiency were 25 percent more likely than other asthmatics to have had at least one flare-up in the recent past. “Our results add more evidence to the link between Vitamin D and asthma, suggesting beneficial effects of Vitamin D on asthma exacerbations. Vitamin D has significant immunomodulatory effects and, as such, was believed to have an effect on asthma -- an immunologically mediated disease," said Dr. Ronit Confino-Cohen.
Based on these study findings, the researchers suggest monitoring serum vitamin D levels in people experiencing uncontrolled asthma despite existing treatments. Apart from sunlight exposure, the researchers also recommend turning to dietary sources of vitamin D and supplementation to reduce the frequency and severity of asthma attacks.
