What is Post-Nasal Drip?
Post-nasal drip occurs when excess mucus produced in the sinuses begins to drip down the throat instead of moving normally through the nasal passages. Your body makes mucus every day to trap dust, bacteria, and irritants, but when you are sick or dealing with allergies, it produces much more than usual.
This excess mucus settles at the back of your throat, causing irritation. Because you lie flat while sleeping, the drainage becomes more noticeable and often more bothersome at night.
Common Symptoms of Post-Nasal Drip
Post-nasal drip can present in several uncomfortable ways. The most common symptoms include:
- Frequent throat clearing
- A sensation of mucus stuck in the throat
- Persistent cough, especially at night
- Hoarseness or voice changes
- Sore or scratchy throat
- Bad breath due to mucus buildup
If your symptoms worsen when you lie down or try to sleep, it’s a strong sign that post-nasal drip is the cause.
Post-Nasal Drip During a Cold
Yes, a cold can definitely trigger nighttime post-nasal drip. Viral infections irritate the nasal passages and cause inflammation, leading to thicker mucus production. As your nose becomes congested, your body redirects that mucus downward instead of outward.
At night, several factors make the drip worse:
- Lying flat encourages mucus to pool in the throat.
- Dry bedroom air thickens mucus.
- Congestion increases due to reduced airflow.
This combination often results in coughing fits, difficulty sleeping, and waking up with a sore throat.
Preventing and Treating Post-Nasal Drip
Although you can’t instantly stop post-nasal drip, several remedies help loosen mucus and ease irritation:
- Stay hydrated: Drinking water thins mucus, making it easier to clear.
- Use a humidifier: Moist air keeps mucus from drying out and worsening symptoms.
- Try saline sprays or rinses: These flush out irritants and reduce congestion.
- Sleep with your head elevated: This prevents mucus from pooling in your throat at night.
- Warm teas and soups: These soothe the throat and help break up mucus.
Over-the-counter decongestants or antihistamines may also help, depending on the cause.
