Southern states found to have more allergy issues
The farther south you live, the more likely you are to deal with allergies and asthma.
A recent study found that living closer to the equator may increase the risk.
This isn’t just because of increased pollen counts; researchers theorize that greater Vitamin D production caused by UV exposure may change the immune system.
Those changes, they said they think, may lead to elevated risks for allergy problems.
