Don't Smoke
Cigarette smoking is the major cause of lung cancer and chronic obstructive pulmonary disease (COPD), which includes chronic bronchitis and emphysema. Cigarette smoke can narrow the air passages and make breathing more difficult. It causes chronic inflammation, or swelling in the lung, which can lead to chronic bronchitis. Over time cigarette smoke destroys lung tissue and may trigger changes that grow into cancer. If you smoke, it's never too late to benefit from quitting. The American Lung Association can help whenever you are ready.
Avoid Exposure to Indoor Pollutants That Can Damage Your Lungs
Secondhand smoke, chemicals in the home and workplace, and radon all can cause or worsen lung disease. Make your home and car smokefree. Test your home for radon. Avoid exercising outdoors on bad air days. And talk to your healthcare provider if you are worried that something in your home, school or work may be making you sick.
Minimize Exposure to Outdoor Air Pollution
The air quality outside can vary from day to day and sometimes is unhealthy to breathe. Knowing how outdoor air pollution affects your health and useful strategies to minimize prolonged exposure can help keep you and your family well. Climate change and natural disasters can also directly impact lung health.
