A collapsed lung (pneumothorax) occurs when air leaks into the space between the lung and chest wall, causing the lung to collapse partially or fully. While some causes (like trauma or underlying lung disease) can’t always be prevented, here are 8 ways to reduce the risk:
1. Avoid Smoking & Vaping
- Smoking damages lung tissue and increases the risk of bullae (air sacs) that can rupture.
- Vaping may also harm lung health. Quitting reduces risks.

2. Protect Yourself from Chest Injuries
- Wear seat belts to prevent trauma in car accidents.
- Use proper safety gear in contact sports or high-risk jobs.
3. Be Cautious with Scuba Diving & Flying

- Divers should follow proper ascent guidelines to avoid lung pressure changes.
- Those with previous pneumothorax should consult a doctor before flying or diving.
4. Manage Underlying Lung Conditions
- Conditions like COPD, asthma, or cystic fibrosis increase risk. Follow treatment plans.
- Get regular check-ups if you have a history of lung disease.
5. Avoid Sudden Pressure Changes
- Activities like skydiving, mountain climbing, or playing wind instruments can strain lungs.
- If you’ve had a collapsed lung before, discuss risks with a doctor.
6. Practice Safe Medical Procedures
- Some medical interventions (like mechanical ventilation, lung biopsies, or acupuncture near the chest) can accidentally cause a pneumothorax.
- Ensure procedures are done by trained professionals.
7. Recognize Early Symptoms
- Sudden sharp chest pain, shortness of breath, or rapid heart rate could signal a collapse.
- Seek emergency care if symptoms appear.
8. Strengthen Lung Health
- Regular exercise improves lung function.
- Deep breathing exercises may help maintain lung elasticity.
When to See a Doctor
If you’ve had a collapsed lung before, you’re at higher risk for recurrence. Follow-up care is crucial. Some cases require surgery to prevent future episodes.
