Centers for Disease Control and Prevention studies from 2007 found that 34 million Americans had been diagnosed with asthma.

Symptoms from allergies and asthma can range in severity from inconvenient to very dangerous and are usually triggered by exposure to allergens. According to an Earth911.com article, triggers such as air pollution or high pollen levels are well-known, but more surprising sources of allergens can lurk in facilities and homes.

Removing indoor allergens and triggers can reduce allergy and asthma symptoms. As part of its social sustainability initiative, the American Cleaning Institute is getting the word out about cleaning for allergies and asthma.

"It is human nature to sometimes overlook the simplest solutions to one of life's problems," said Nancy Bock, ACI's Senior Vice President of Education. "Sometimes, a simple change in a routine behavior can have a major impact on allergy and asthma sufferers."

The most common indoor allergens or triggers are pet dander, mold and mildew, dust mites, cockroaches and pollen from outside that finds its way in. Here are a few ways that changing up your green routine can reduce your exposure.

Every home has dust mites, but they can be controlled and significantly reduced by washing fabrics such as bedding and curtains more often. As long as you're updating your laundry routine, you can also save a little extra money and energy by incorporating concentrated cleaning products. Also, making a habit of wiping down bathroom surfaces and wet-mopping floors helps eliminate mold and mildew.

Dusting, vacuuming and sweeping are useful for removing pollen and dust mites. By doing these things more regularly, those allergens don't have a chance to build up and trigger symptoms. Take the time to shake out rugs and keep window sills and door frames clean.
