When it comes to asthma and allergies, your wellness may come down to where you live. This is according to a new study released in Annals of Allergy, Asthma & Immunology, the scientific journal of the American College of Allergy, Asthma and Immunology (ACAAI), which argues that those living near the equator may find themselves sneezing and wheezing more than usual, and not because of increasing pollen counts.
According to lead study author Vicka Oktaria, MPH, living in locations closest to the equator can put you at increased risk of developing allergy and asthma. ‘UV-B rays’ exposure is higher for people living in areas closer to the equator. This increase in UV-B may be linked to vitamin D, which is thought to modify the immune system. These modifications can lead to an elevated risk of developing allergy and asthma,’ said Oktaria.
It is already known from previous studies that because of differences in climate, housing, socialising and culture, a variation in airborne allergens can be reflected by latitude. However, this study moves the evidence forward because it is one of the first that uses an individual’s UV-B exposure and latitude location to examine the association with allergies and asthma.
Allergist Richard Weber, MD, who is also the president of ACAAI, explained that ‘Allergies and asthma are serious diseases that can be life-threatening if not diagnosed and treated properly.’ He went on to say that ‘Both conditions can be more than bothersome for people, no matter their geographic location, and can last year-round.’
According to the ACAAI, if you have an allergy you may also experience asthma symptoms. It is estimated, in fact, that 75 to 85% of asthmatics have an allergy. If you believe you have either condition, you should consult a board-certified allergist, because they are the best-trained health professionals for performing testing and for treating both asthma and allergic diseases effectively.
