Breathlessness ranges from a normal response to exertion to a . It is crucial to distinguish between breathlessness that can be managed at home and breathlessness requiring emergency care. When in doubt, call for help.
Common Causes
- Asthma — most common in young people
- COPD — especially in smokers
- and panic attacks — hyperventilation
- Anaemia — insufficient red blood cells
- Physical deconditioning — breathlessness from lack of fitness
- Obesity — restricts diaphragm movement
- infections — pneumonia, COVID-19
- Heart failure
- Pulmonary embolism — blood clot in lung (emergency)
- Allergic reaction with airway narrowing (emergency)
Home Care and Relief
Sit upright and lean forward slightly
The most important immediate step. Sit upright, lean slightly forward with hands on knees. Opens the chest and allows the diaphragm to work more efficiently.
Pursed lip breathing
Breathe in slowly through the nose for 2 counts. Purse lips and breathe out for 4 counts. Slows breathing rate and reduces air trapping.
Diaphragmatic breathing
One hand on chest, one on abdomen. Breathe so the abdomen rises. Breathe in for 4 counts, out for 6. Most efficient breathing technique.
Use prescribed inhaler correctly
Shake well, breathe out fully, inhale slowly while pressing, hold breath for 10 seconds. Using a spacer improves delivery significantly.
Fan directed at the face
Airflow from a handheld fan directed at nose and mouth significantly reduces the sensation of breathlessness.
Remove the trigger
Move away from allergens, smoke, or dust. Open windows for fresh air.
Clinical guidance from NHS[1] stresses matching home care to symptom severity and seeking urgent review when red-flag signs appear.
