Maximum breathing capacity may decline by about 40% between the ages of 20-70. However, most of us do not notice much change in the functioning of our lungs.
• The diaphragm tends to weaken with time
• The chest wall becomes stiffer, making it a little harder for the lungs to expand and contract
• Slightly less oxygen is absorbed from the air we breathe in
• Increased vulnerability to respiratory infections such as the flu and pneumonia
• The lungs may be less able to fight off infection as the immune system weakens
• Vigorous exercise may be more difficult, especially for people who are not physically fit
What we can do
Tobacco smoke contains many chemical compounds that damage the lungs. Smoking also inhibits our lungs’ ability to clear bacteria from secretions in larger airways.
Exercise increases lung capacity, lessens the stiffness of the chest wall and lungs and may also decrease our risk of suffering from a respiratory infection.
Those who are 65 or older should get vaccinated against influenza and pneumonia.
Stay away from chemical fumes and other irritants.
Our lungs and immune system need nutrition to stay healthy. Good nutrition boosts our ability to handle infections.
We need to protect our respiratory system by adopting healthy habits.
