Coughing is a protective reflex that clears secretions, irritants, and foreign material from the airways. Acute coughs — lasting less than 3 weeks — are most commonly caused by viral upper respiratory infections and are self-limiting. Subacute coughs (3-8 weeks) often represent post-infectious airway hypersensitivity.

What lifestyle changes can help with coughing?

Identifying and addressing triggers — allergens, acid reflux, dry air — is foundational. Staying well hydrated supports mucosal clearance. Steam inhalation, honey, and warming herbs have traditional and some evidence-based support for irritant cough. Avoiding irritants including tobacco smoke and air pollutants.

What integrative approaches support coughing?

Cough is one of the most common reasons for medical consultation. Acute cough is usually viral and self-limiting. Chronic cough (over 8 weeks) has multiple causes including upper airway cough syndrome, asthma, and gastro-oesophageal reflux disease (GORD). Honey has evidence for reducing cough in children. Acupuncture has emerging evidence for chronic cough.

When should I seek professional support for coughing?

Cough lasting more than 3 weeks without improvement. Cough producing blood or rust-coloured sputum. Cough accompanied by breathlessness, weight loss, or night sweats. Cough in a smoker with any change in character. Cough in a child causing breathing difficulty.
