When you have chronic obstructive pulmonary disease--or COPD--it's important to understand your triggers and know what you can do to avoid them.

Avoiding your triggers can help keep your COPD symptoms from flaring up and help you breathe easier.

The flu and pneumonia are two big triggers.

So protect yourself by getting vaccinated for both, wash your hands regularly, and avoid people who have a cold or the flu.

Air pollution is also a big trigger.

When the air turns bad, stay indoors with the windows shut.

It may also help to use an air filter in your home, and an air conditioner during the summer.

If you use a woodstove or fireplace to heat your home, have it inspected to make sure it's working right and sending smoke up the chimney--and not into your home.

Chemical fumes can also be a trigger.

So learn about safer products for your home, and keep the room well ventilated when you clean or paint.

If you have allergies, they can be a trigger too.

So avoid things you might be allergic to, like pollen, mold, or dust mites.

COPD inhalers can deliver medicine right to your lungs where it's needed, but it can be hard to use them right.

Be sure you understand how and when to take the medicine your doctor has prescribed for you.

And if you smoke, quitting is probably the most important step you can take to prevent or slow damage to your lungs.

Remember--it's never too late to quit smoking.

By knowing and avoiding your triggers, you can live better with COPD.
