🫁 What is Lung Capacity?
According to the American Lung Association, lung capacity refers to the total amount of air your lungs can hold.
Key measurements: Total Lung Capacity (TLC), Vital Capacity (VC), and Forced Vital Capacity (FVC).
📊 Normal Values & Factors
Based on NHLBI guidelines, normal lung capacity varies by:
- Age (decreases ~20ml per year after 25)
- Height (taller = larger capacity)
- Gender (males typically 20-25% higher)
- Fitness level and smoking history
💡 Improving Lung Health
Recommendations from CDC respiratory health guidelines:
- Regular aerobic exercise
- Deep breathing exercises
- Avoid smoking and secondhand smoke
- Maintain good air quality indoors
