If you have asthma, you know that symptoms can come on quickly, then worsen.

The things that make them do that are called triggers. An important part of managing asthma is knowing your triggers at home, work, school or while you’re outdoors.

A health care provider can help you figure that out, then you can take steps to avoid those triggers and breathe easier.

At Home
Because asthma is usually due to allergies, triggers are often allergens, or things that cause allergic reactions. Allergens such as pet dander, dust mites, pests and smoke can make asthma symptoms worse in some people, and for others, even trigger an asthma attack.  

The National Heart, Lung, and Blood Institute (NHLBI) suggests that it may be helpful to combine a few different strategies to help reduce exposure to triggers.

People sensitive to dust can clean with a high-efficiency particulate air (HEPA) filtration vacuum and use mattress and pillow covers that prevent exposure to dust mites. If you’re sensitive to pests like cockroaches and rodents, consider integrated pest management, which involves removing and controlling pests through methods such as traps or poison. Avoiding tobacco smoke, including secondhand smoke, can be especially helpful for some people with asthma.

At School
Asthma is one of the leading reasons children miss school. At school, kids may be exposed to dust mites, pests and mold, which may be asthma triggers for some children.

Because children spend lots of time at school, it can be helpful for teachers, school nurses or coaches to know what to do if your child’s symptoms flare up. Team up with a health care provider to develop an asthma action plan and share it with trusted adults at your child’s school.

At Work
The workplace can have hundreds of potential triggers, like chlorine-based cleaning products, bleaches, hair dyes and metal dust. Repeated exposures in the workplace can also lead to new triggers. Report new or worsening symptoms that occur at work to your health care provider and your workplace supervisor.

Outdoors
Everyday weather like cold, dry air can set off breathing problems. Air pollution can affect asthma, too.

It may be helpful to avoid some of the worst pollution by adjusting when and where you exercise. Try to avoid exercising near busy roads or industrial areas. Visit airnow.gov to check your local air quality so you can plan to avoid outdoor activities when pollution is highest.

Managing your triggers is just one part of keeping your asthma under control. Work with a health care provider to develop an asthma treatment plan that includes taking medicines as prescribed and keeping track of your symptoms and where you are when they occur. That way, you can know what’s making your asthma worse or better.
