11 Respiratory Health Tips for Better Lung Function

11. Monitor Your Lungs and See a Professional

Regular monitoring helps catch changes early so you can act before problems worsen. Watch for persistent cough, unexplained breathlessness, increased wheeze, or reduced exercise tolerance. Primary care clinicians can perform basic checks and refer for spirometry or pulmonary function tests when needed. Normal forced vital capacity (FVC) in adults often ranges from about 3–5 liters and may decline roughly 0.2 liters per decade in healthy individuals; your provider can interpret results in context. If you have a history of smoking, occupational exposure, or chronic symptoms, ask about a formal lung function test. Early detection of conditions like asthma, COPD or interstitial lung disease improves treatment options. Keep a simple breathing diary—notes on cough, sleep quality, and how far you can walk without stopping—and bring it to appointments. For persistent or worsening symptoms, fast referral to a respiratory specialist gives the best chance of preserving function and quality of life.
