Most coughs after a viral illness improve on their own. The tips here are supportive comfort measures, not treatments for an infection. A cough lasting more than a few weeks, or one with fever, breathlessness, or coughing up blood, needs medical evaluation.
Why does a cough linger after a cold?
After a viral infection, the airways can stay irritated and produce extra mucus for days or weeks, keeping the cough going even after you feel better. Staying hydrated, using a humidifier, and resting all help the airways recover. Adding moisture to the airways is the common thread in most comfort measures.How can nebulized saline help?
Inhaling sterile 0.9% saline mist adds moisture to the airways and can help thin and loosen mucus, making it easier to clear. The MistPro delivers saline as an ultra-fine 1–5 micron mist in about 5–7 minutes, and saline is available over the counter — see saline explained. This is a soothing, drug-free option for a stubborn cough or congestion.What about hypertonic saline?
More concentrated hypertonic saline (3% or 7%) is sometimes used to mobilize thick mucus, but it can trigger coughing or airway tightening in sensitive people. Ask your doctor before using it, especially for children — see compatible medications.What else helps at home?
- Hydration — fluids thin mucus naturally.
- Warm steam from a shower and a bedside humidifier.
- Honey for adults and children over one year (never for infants).
- Elevating your head at night.
