Geographic Location Increases Risk of Developing Allergy and Asthma

It is not the amount of pollen in the atmosphere that causes allergies and asthma; the geographical factors also play a crucial role in increasing the risk of developing allergy and asthma. That's why the people residing close to the equators often find themselves sneezing and wheezing.

According to a recent study conducted by the American College of Allergy, Asthma and Immunology (ACAAI), the people living in locations closest to the equator are at a higher risk of developing asthma and allergy.

"UV-B rays exposure is higher for people living in areas closer to the equator," Vicka Oktaria, MPH, lead study author, was quoted as saying in Medicalxpress. "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."

Studies done earlier showed how latitude can display a difference in the air allergens that occurs as a result of climate, social and cultural differences. But this latest finding is the first study of its kind that was done using individuals' latitude location and UV-B exposure in order to find the relation with allergy and asthma. 

According to Richard Weber, M.D., ACCAI president, allergy and asthma are life-threatening diseases if they are not diagnosed at the right time and are not treated well.

The ACAAI reports that those who suffer with allergies can also have symptoms of asthma. Nearly 75 to 85 percent of asthma patients suffer from allergy.

The findings were published in the scientific journal of the ACAAI, journal Annals of Allergy, Asthma and Immunology.
