If your puffy eyes and runny nose haven’t already told you, the blanket of yellow pollen on your car and every other horizontal surface in the past few days has certainly signaled the season to be ready for the allergens that are everywhere.
Here are some tips from Natural Insights for Well Being, to help you with your Spring health goals.
New studies reveal vitamin D benefits in both pneumonia and asthma
Vitamin D reduces pneumonia
Recent studies have highlighted a link between low levels of vitamin D and pneumonia in older adults living independently. In this study, doctors measured vitamin D levels in 16,974 people, at least age 17, and compared their histories of pneumonia. After adjusting for seasonal differences, body mass index scores, smoking, lung, heart and other chronic diseases, researchers found that those with vitamin D levels below 30 nanograms per milliliter of blood (ng/mL) were 56 percent more likely to develop pneumonia compared to those whose vitamin D levels were 30 ng/mL or more.
Doctors said that the optimal range may begin at 30 ng/mL rather than at 20 ng/mL for vitamin D.
More vitamin D, less asthma
Doctors said there are few studies of the effect of vitamin D on asthma severity in adults. In this trial, researchers separated 121 asthmatic adults into five groups based on levels of circulating vitamin D.
Those whose vitamin D levels fell below 30 ng/mL were five times more likely to have severe asthma as were those whose vitamin D levels were 30 ng/mL or more. Researchers also found that, for every 1 ng/mL increase in circulating vitamin D, chances of being hospitalized or seeking emergency treatment for asthma declined by 10 percent.
Discussing their findings, doctors said vitamin D activates the immune anti-microbial response and helps reduce air-passageway inflammation and sensitivity to asthma triggers such as cold weather, dust, and smoke, easing symptoms and improving respiratory health.

Probiotics for Hay Fever
In hay fever, the immune system mistakenly identifies usually harmless allergens such as pollen, dust or mold, as “intruders,” releasing histamines that cause itchy, watery eyes, sneezing, and runny nose. In this study, 425 men and women with hay fever who were continuing to take a standard over-the-counter antihistamine took a daily dose of the probiotic Lactobacillus paracasei or a placebo. After five weeks, those taking probiotics reported much less eye itching and tearing while the placebo group had not improved. Doctors said this is the first study to show a probiotic is an effective add-on to the recommended therapy for hay fever.
