Stop smoking. If you smoke, quit. That's the most important thing you can do to stop more damage to your lungs. If you need help, ask your doctor for advice. It's also key to avoid secondhand smoke. Smoke irritates your lungs and makes it even harder to breathe.

Get fresh air. Try to avoid other things that can bother your lungs, too. Stay inside on days when you know pollution or pollen is bad. Stay away from fumes and dust.

Exercise. It can be hard to move when you can’t catch your breath. But regular exercise can improve your endurance and strengthen the muscles that help you breathe. Ask your doctor which exercises are right for you.

Eat healthy. You're probably using more energy to help you breathe. A well-rounded diet will give you the strength you need to stay active and healthy.

Be aware of your weight. Because it takes so much energy to breathe, you might be underweight. Your doctor can suggest supplements if a healthy diet doesn't help you get to a good weight. If you're overweight, losing extra pounds can make your breathing easier.

Avoid chemicals. Skip scented products like soaps and perfumes. When you clean, use natural products without a scent. They might not bother your breathing as much.

See your doctor regularly. Go to all of your checkups, even if you feel fine. It's important for your doctor to see how well your lungs are working. Bring a list of all your medicines to each visit. Make a note of any changes, and call if your symptoms get worse or if you have any new ones.

Take your medicine. Follow the treatment plan your doctor gives you. Take your medicine exactly as prescribed and listen to any other advice she has on how to take care of your COPD. If you have any questions, be sure to ask.
