Breathlessness ranges from a normal response to exertion to a medical emergency. 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
Anxiety and panic attacks — hyperventilation
Anaemia — insufficient red blood cells
Physical deconditioning — breathlessness from lack of fitness
Obesity — restricts diaphragm movement
Respiratory 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.

When to See a Doctor

Sudden severe breathlessness — call 112
Breathlessness at rest
With chest pain
Blue lips or fingertips
With high fever
Asthma not improving with inhaler within 15 minutes
With swollen legs
