Vitamin D deficiency appears to be associated with worsening asthma. Recent studies show an association between low vitamin D levels and severe asthma attacks, including an increased rate of emergency room visits and hospitalizations for asthma. Other studies show that when asthmatics have higher levels of vitamin D, they have decreased amounts of allergic antibodies and eosinophils, less emergency room visits for asthma, as well as less need for controller therapies.
It is not yet known if vitamin D supplementation will help treat asthma in people with low vitamin D levels, although studies suggest that it would. Unfortunately, it is possible to overdose on vitamin D, so it is important to talk with your doctor before taking any vitamin D supplementation. Vitamin D might be best obtained by getting a reasonable amount of sun exposure, such as 15 minutes a day for 2 to 3 days a week. One thing is for sure -- humans were not meant to spend their entire lives indoors – so get outside and enjoy some sunshine on a regular basis. But like anything else, moderation is key, so don’t overdo it.
