2. Healthier Lungs
Within just a few weeks of quitting, the tiny cilia in your lungs begin to heal and regain function.
These hair-like structures help clear out mucus and debris, so you’ll notice less coughing and chest congestion.
As your lungs recover, breathing becomes noticeably easier and your risk of lung infections drops.
Over time, your overall lung function improves, making physical activities and exercise far less taxing.
