How to Loosen Phlegm and Mucus Naturally
Phlegm can occur with a cold, allergies, post-nasal drip, asthma, smoking, or a respiratory infection. You usually don’t need to “cleanse” your lungs; the aim is to thin mucus and make it easier to clear.
- Drink plenty of fluids. Hydration can help keep mucus thinner.
- Try warm drinks, such as tea or broth, to soothe the throat.
- Use humidified air or take a warm shower if it makes breathing more comfortable. Avoid very hot steam because of burn risk.
- Try saline nasal spray/rinsing if mucus is coming from nasal congestion or post-nasal drip. For nasal irrigation, use sterile/distilled water or water that has been boiled and cooled.
- Avoid smoking and secondhand smoke, which can increase mucus and irritate the airways.
- Sleep with your head slightly elevated if mucus and coughing are worse when lying down.
- Honey can soothe a cough in adults and children over 1 year old, although it doesn’t treat the underlying cause.
When to seek medical care
Get urgent medical attention for difficulty breathing, chest pain, coughing up blood, bluish lips, confusion, or rapidly worsening symptoms. A persistent cough or ongoing chest mucus should also be evaluated, particularly if it lasts several weeks.
And don’t assume that green or yellow mucus automatically means you need antibiotics—mucus color alone doesn’t reliably determine the cause.
