What factors affect lung capacity?
Age. Usually, a person’s lung capacity starts decreasing after the age of 30. As you grow older, the physical changes in the organs of your respiratory system affect the volume of air your lung can retain.
Sex. Males develop larger lungs than females, thus increasing their lung capacity.
Height. Taller individuals have a higher lung capacity since they have larger chests. However, they are also more likely to experience a significant decrease in lung volume as they age.
Location. When a person stays long enough in a high-altitude area, their body starts to adapt to the air pressure by increasing lung capacity.
Lifestyle. Obesity and smoking can greatly decrease a person’s lung capacity, resulting in less oxygen reaching the bloodstream. Similarly, obesity causes fat to put pressure on the thoracic cage.
