How to Keep Healthy Lungs: 10 Essential Tips for Better Breathing and Lung Health

1. Don't Smoke — and Avoid Secondhand Smoke

Smoking is the single biggest threat to lung health. Cigarette smoke narrows airways, causes chronic inflammation, destroys air sacs, and is the leading cause of lung cancer and COPD.

•    If you smoke, quitting at any age improves lung function within weeks
•    Avoid enclosed spaces with smokers — secondhand smoke is equally damaging
•    Vaping and shisha are not safe alternatives — both cause airway inflammation and long-term damage
