Excess mucus or phlegm in the chest and throat is often caused by a cold, allergies, sinus drainage, irritation from smoke, or respiratory infections. Here are 8 evidence-based ways that may help loosen and clear mucus:
1. Stay well hydrated 💧
Drinking enough fluids helps thin mucus, making it easier to cough up and clear.
Good options:
- Water
- Warm tea
- Clear broths
2. Use steam or humidified air 🌫️
Warm, moist air can help loosen mucus in the airways.
You can:
- Take a warm shower
- Inhale steam from a bowl of hot water (carefully)
- Use a humidifier
3. Gargle with warm salt water 🧂
A salt-water gargle may help soothe throat irritation and clear mucus from the back of the throat.
Mix:
- ½ teaspoon salt
- 1 cup warm water
Gargle and spit out.
4. Try honey 🍯
Honey may help soothe throat irritation and reduce coughing.
Do not give honey to children under 1 year old.
5. Avoid irritants 🚭
Mucus production can increase with exposure to:
- Cigarette smoke
- Air pollution
- Strong chemical fumes
Reducing exposure may help symptoms improve.
6. Use saline nasal rinses 👃
If postnasal drip is contributing to throat mucus, saline sprays or rinses can help clear the nasal passages.
Use sterile, distilled, or previously boiled water for nasal irrigation.
7. Consider over-the-counter expectorants 💊
Some medications containing Guaifenesin may help thin mucus, making it easier to cough up.
Follow package directions and consult a healthcare professional if you have underlying medical conditions.
8. Rest and address the underlying cause 😴
Phlegm is a symptom, not a disease. The best treatment depends on the cause, such as:
- Common cold
- Allergic rhinitis
- COVID-19
- Bronchitis
- Gastroesophageal reflux disease
🚨 When to seek medical care
Contact a healthcare professional if:
- Symptoms last more than a few weeks
- You have difficulty breathing
- You cough up blood
- You have a high fever
- Chest pain develops
- The mucus is accompanied by significant wheezing or worsening illness
Bottom line
Most mucus and phlegm improve with hydration, steam, rest, and treating the underlying cause. If symptoms are severe, persistent, or accompanied by breathing problems, medical evaluation is important.
