The lungs have a natural ability to heal.
Dr. Charlotte Dean, head of the research group for lung development and lung diseases at Imperial College London, explains to The Guardian that they can repair damage once the strain from smoking stops.
This is because the lungs are essential for the body’s survival and are therefore designed to withstand factors such as pollution and infections.
When a person stops smoking, the body gradually begins to rebuild some of the damaged tissue. For many, this leads to improved lung function over time.

Not the same for everyone
Although the body can heal, it does not happen in the same way for everyone. Some people develop permanent damage that cannot be reversed.
This may be due to genetic factors or how long and how much a person has smoked.
Age also plays a role. The older a person is, the more difficult it becomes for the body to repair itself. Therefore, the timing of smoking cessation is highly significant.
More than just quitting smoking
A healthy lifestyle can support the lungs. Exercise can improve the body’s ability to absorb oxygen and thereby support lung function.

This makes it easier for the body to function more effectively in everyday life.
Nevertheless, it is important to understand that previous damage may have long-term consequences. The risk of disease may still be elevated.
The key point is that the lungs can heal after smoking, but not necessarily completely, and some damage may be permanent.
