How the Lungs Heal After Quitting Smoking (2024)

Smoking is the top cause of preventable death globally, causing more than 450,000 deaths every year from firsthand and secondhand smoke.

We all understand the dangers of smoking to lung health, but we don’t often discuss how exactly the lungs heal after someone quits smoking.

No matter how long you’ve smoked, quitting at any time can have positive effects for your lungs and your overall health. About tried to quit in 2015, and millions of Americans make the same attempt every year. If you’re one of them, here’s how quitting will help your lung health.

The Benefits of Quitting Smoking

The risk of getting lung cancer is significantly reduced the longer someone goes without a cigarette. Someone who has spent a decade smoke-free is 50 percent less likely to get lung cancer compared to someone who continues to smoke, according to the Centers for Disease Control & Prevention (CDC). However, a former smoker still has a greater risk of getting lung cancer than someone who has never smoked.

On average, about 4.5 percent of Americans quit smoking annually, but as of 2015 smoking cessation rates increased to 5.6 percent, indicating more people are trying to make a positive change for their health.

Quitting is so beneficial because cigarettes contain more than 4,800 toxic chemicals, most of which produce harmful effects in the lungs and airways.

When you stop smoking, the lungs begin to heal immediately. Carbon monoxide gradually leaves the bloodstream, which helps to alleviate symptoms like shortness of breath. Smoking also inflames the lining of the airways, but when you quit, you no longer inhale all the toxic substances that irritate the airways, which allows them to begin healing.

Preparing to Quit

If you plan to quit smoking, take steps now to adequately detox your lungs. Drink more water to help the body rid itself of toxins and other carcinogens. Change your diet, consume less salt and sugar and increase your intake of nutrient-rich foods that will help your body grow new, healthy tissues. Also consider increasing your level of physical activity. Yoga, in particular, is a good option because you’ll learn breathing techniques that open up the lungs.

Even if you’ve tried several times before to stop smoking, it’s never, ever too late to quit. Even within a day of quitting, your lung health and blood pressure will improve. Continuing to stay smoke-free will help you avoid symptoms like shortness of breath, coughing and conditions like emphysema and lung cancer that dramatically reduce your quality of life or could lead to early death.

Your lungs are a vital organ, and every puff of a cigarette affects their function. Quitting will noticeably improve your lung health, so get help today and find out about smoking cessation programs and resources in your local area. Stopping this habit takes time, so extra support could help you quit and remain smoke-free permanently.
