When there is too much carbon dioxide in the body, this can result in symptoms such as fatigue and breathlessness.
As a person ages, muscles and tissues around the airway structures become weak, causing the airways to close too quickly.
In addition, the tiny air sacs that exchange oxygen and carbon dioxide inside the lungs (alveoli) become distorted and are unable to function properly. When this happens, the lungs can no longer exchange oxygen and carbon dioxide effectively.
Nervous System Changes
Average lung capacity by age decreases because some parts of the brain that control breathing won’t be as effective as it was before. This results in insufficient oxygen reaching your lungs. The lungs may not be able to exhale enough carbon dioxide as well. As a result, a person experiences difficulty in breathing, and tiredness.
As you age, your airways become less sensitive to triggers, making it difficult to cough up any germs, smoke, or particles in the lungs. Because of this, an accumulation of particles and even bacteria may reside in the lungs.
Immune System Changes
Average lung capacity by age is also affected by the immune system. You may become more susceptible to infections as you age. As a result, your body will have a much harder time fighting off bacteria and viruses that can cause lung infections and other illnesses.
Additionally, your lungs will have a harder time recovering from any lung infection or disease.
Average Lung Capacity By Age: Keeping Your Lungs Healthy
The aging of your lungs is inevitable, but there are things that you can do to minimize its effects and maintain a good average lung capacity by age. The simplest way to do this is to protect your lungs. You can protect your lungs by following these tips:
Do Not Smoke
Smoking damages lung tissue, preventing them from functioning properly. In addition to lung diseases, smoking can also cause lung cancer.
