Belgian Lung Foundation

The lungs provide exchange of oxygen from the air to the bloodstream and carbon dioxide from the bloodstream to the air. Oxygen is very important for the functioning of all cells in our body. The gas exchange process is essential for survival and proper functioning of our body. If the lungs do not work well, it affects not only our ability to breathe but also the health of other important organs, such as the heart and brain.

The lungs are constantly in contact with the outside air, which exposes them to many pollutants and irritants, such as cigarette smoke, vape vapours, air pollution, chemicals, and even pathogens like viruses and bacteria. Long-term exposure to these risk factors can lead to chronic respiratory diseases such as asthma, chronic obstructive pulmonary disease (COPD) or lung cancer.

Respiratory diseases affect millions of people around the world but are often not diagnosed properly and timely, or are misunderstood. Many people underestimate early symptoms such as a chronic cough, shortness of breath, or fatigue, attributing them to other causes. This lack of attention can lead to delays in diagnosis, while respiratory diseases are often more treatable if detected early.

Healthy lungs help maintain good energy expenditure levels, allowing a person to do sports, exercise and live actively. In contrast, damaged lungs can limit mobility, cause constant shortness of breath, and significantly reduce quality of life. Simple daily activities such as climbing stairs, walking, or even talking can become very fatiguing for someone with a respiratory disease.

Many respiratory diseases are predictable and avoidable. By quitting smoking and vaping, avoiding polluted environments, adopting an active lifestyle, and ensuring that we live in spaces with good air quality, we can protect our lungs and reduce the risk of developing severe respiratory diseases. Prevention through simple actions is one of the best ways to ensure long-term respiratory health.

Proper functioning of the lungs is also important for the mental well-being. A person who breathes well feels less stressed and has more energy. On the other hand, respiratory diseases can lead to anxiety, depression, stress, or chronic fatigue, affecting amongst others sleep quality and the ability to fully enjoy life.
