Why do people have allergies to a chemical in your shower?

A new study suggests that some people may have a genetic predisposition to allergies.

The finding could help scientists better understand the causes of allergic reactions.

Scientists at the University of Florida found that about 5 percent of the American population has an allergic response.

While that number may seem low, that’s a significant percentage, especially in a country where allergies have increased in recent years, including asthma and hay fever.

That’s a problem because the symptoms of allergy are often similar to those of asthma.

In other words, they can mimic one another.

“The allergic response to air pollution can mimic asthma in some people,” said the study’s lead author, David E. O’Brien, an assistant professor of medicine and director of the Center for Environmental Health Research at the university.

Ostrich and duck feathers have been the subject of a number of allergies, including to the chemicals used to manufacture them, and the chemical found in duck feathers is a common one in the environment.

Ours is an extreme case.

While most people have no trouble breathing through their nose, there are some people who are allergic to the feathers.

But for the most part, they’re not allergic to duck feathers.

So O’Brian and his colleagues used a large-scale study to test the genetic predispositions of people who reported having an allergic reaction to duck feather products.

That included people with asthma, hay fever and eczema.

They asked them to fill out a questionnaire on the health of their environment and how often they’d had an allergic or allergic-like reaction.

People with asthma were more likely to have an allergy to duck products than the general population.

People were also more likely than the non-athletics to have hay fever or eczma.

The researchers found that people with a genetic susceptibility to allergies were more susceptible to a reaction to these products than people without one.

This is an important finding because it could help doctors better understand what causes allergies and how to treat them.

It could also help researchers better understand how and why allergies develop in the first place.

O”The findings show that individuals with a predisposition for asthma and other allergies may have been predisposed to an allergic effect,” said study author and assistant professor John C. Smith, professor of pathology and allergy medicine at the school of medicine.

Smith is also director of asthma and allergy clinic at the Center on Asthma, Immunology and Immunopathology at the Sanford-Burnham Medical Center.

“It could also give us an idea of what’s going on with other common allergens in the air we breathe, like pollen, mold and other allergens that could trigger allergies,” Smith said.

“A genetic predispose is the idea that the immune system is in a certain way more vulnerable than other tissues or systems in the body.”

People with a gene mutation that is associated with allergies were much more likely and less likely to develop asthma or hay fever than people with other genes that don’t cause allergies.

In the study, which was published online March 12 in Nature Medicine, researchers followed more than 7,000 people who had asthma.

They then collected urine samples for 24 hours to look for pollen and other common airborne allergens.

In one part of the study they also collected samples of people’s hair to look at whether they had an allergy.

And in the other part of it, they looked at the composition of their skin to see if they had a skin allergy.

Overnight, researchers found there were a wide variety of allergies in people with genetic susceptibility, including hay fever, eczmia and asthma.

The people with the most allergies were people who were genetically predispressed to allergies and their reactions tended to be more severe.

That finding is a surprise, said co-author Michael C. Eichenbaum, a professor of dermatology and allergy science at the hospital.

“I expected to find some correlation between asthma and genetic predisposing,” Eichenbus said.

But he said that his own research suggests a different result.

“There’s an association between genetic predispoitions to asthma and allergic reactions,” he said.

That said, Eichenbuch said he wasn’t surprised to find a correlation between genetic susceptibility and allergies.

“You see a lot of correlation between genetics and allergies,” he told Live Science.

“We just didn’t see that connection.”

O’Briens research also showed that people who live in areas with higher levels of indoor pollutants had more allergies, and that they had higher rates of asthma than people who lived in areas that were cleaner.

But there was no relationship between pollution levels and the risk of asthma or other allergies.
