Cooler temperatures and lower humidity create the perfect conditions for cold and flu viruses to survive and spread. Although annoying, colds and flus are self-limiting for many people but can leave behind a nagging cough that is harder to treat. We look at ways to manage the cough and a reminder to prepare for winter.
Post-viral cough
A cough can be caused by infections (colds, bronchitis, flu, Covid-19), asthma, aspiration, medicines, diseases as well as more serious infections. If it lasts less than three weeks, symptom relief is the primary goal, but coughs lasting more than eight weeks should be investigated to find the cause.
A post-viral cough is dry and unproductive, following an infection when the airways are still irritated. It can last three to eight weeks. Coughing fits can be triggered by cold air, drinks or:
- A post-nasal drip of mucus from your nose onto the back of your throat when lying down.
- Inflammation of the upper airways after an infection.
- Underlying asthma.
