What Causes Coughing Up Mucus When Laughing?
There are a few possible reasons you may cough up mucus when laughing hard:
Postnasal Drip
Excess mucus dripping down the throat from the sinuses is called postnasal drip. It stimulates the gag reflex and leads to coughing. Laughing can make postnasal drip worse by causing throat vibrations that loosen mucus.
Allergies
Allergic rhinitis causes increased mucus production that can drip down the throat. The irritation from allergens also inflames the airways, making coughs more likely when laughing.
Asthma
Asthma is an inflammatory airway disease that produces excess phlegm in the lungs and bronchi. Laughing forcefully can trigger an asthma attack with wheezing, coughing, and thick mucus.
GERD
Gastroesophageal reflux disease (GERD) allows stomach acid to back up into the throat, stimulating mucus production. Laughing puts pressure on the stomach, making reflux and acidic mucus more likely.
Smoking
Cigarette smoking paralyzes the cilia (microscopic hairs) that sweep mucus out of the airways. Smoke also causes goblet cells in the throat to release more mucus. This creates a buildup of phlegm that is coughed up when laughing.
Infection
Bacterial and viral infections like colds, flu, pneumonia, and bronchitis stimulate mucus production. Forceful laughing can dislodge thick infected mucus from the lungs and lead to coughing fits.
What Does the Color of Phlegm Mean?
Paying attention to the color and consistency of mucus coughed up when laughing can provide clues about potential causes:
Clear or White
A small amount of clear or white mucus is normal. Thin, watery phlegm can come from postnasal drip or viral infections. Thicker white discharge may signal airway inflammation from asthma or allergies.
Yellow or Green
Yellow or green mucus often indicates a bacterial infection, like a sinus infection, bronchitis, or pneumonia. Greenish phlegm is thick and can be difficult to cough up.
Brown or Black
Dark brown, grey, or black mucus may come from inhaling pollutants like dirt or smoke. It can also contain dried blood, signifying lung injury or infection.
Pink, Red, or Rust-Colored
Pink, red, or rusty mucus with streaks of blood is common with lung infections like bronchitis or pneumonia. Blood indicates irritation and inflammation of the airways.
Orange
Orange mucus can come from environmental allergens or respiratory conditions. It may also contain dust or red blood cells turned orange through oxidation.
When to See a Doctor
Occasionally coughing up small amounts of mucus after laughing hard is usually not concerning. But make an appointment with your doctor if you experience:
- Persistent cough lasting over 3 weeks
- Coughing up copious, colored phlegm daily
- Wheezing or difficulty breathing
- Fever, chills, or unintentional weight loss
- Cough with bloody, brown, or black mucus
These symptoms may require prescription cough medications, antibiotics for infection, or imaging tests if lung disease is suspected.
How to Clear Excess Mucus from the Lungs and Throat
You may be able to reduce coughing up mucus when laughing through home treatments:
Increase Fluid Intake
Drinking more water can help thin out excess phlegm so it’s easier to expel from the airways. Warm liquids may be especially beneficial.
Use a Humidifier
Running a humidifier adds moisture to the air, helping loosen mucus from the breathing passages. This makes coughing more productive.
Irrigate Sinuses
Use a saline rinse to flush mucus out of the nasal passages. This may reduce postnasal drip and related coughing when laughing.
Take Guaifenesin
Guaifenesin is an over-the-counter expectorant that thins mucus secretions and promotes productive coughing. Ask your doctor if it could help your symptoms.
Use Cough Drops
Cough drops containing menthol or anesthetics can temporarily coat and soothe an irritated throat. This may suppress the urge to cough when laughing.
Try Honey
Honey’s antimicrobial and anti-inflammatory properties can combat mucus-producing infections. Sip some tea with honey to coat and calm coughs.
Use Peppermint
Menthol in peppermint may thin mucus, while the aroma can suppress coughing. Try peppermint tea, drops, or inhaling the essential oil.
Quit Smoking
For smokers, quitting can help clear excess mucus over time as cilia regrow and function improves. This reduces chronic coughing.
When to See an ENT
If home remedies don’t improve coughing up mucus when you laugh, see an ear, nose and throat specialist (ENT). An ENT can check for issues like:
Chronic Sinusitis
Ongoing sinus congestion can cause postnasal drip. An ENT may prescribe steroid nasal sprays or antibiotics to treat bacterial sinus infections.
Vocal Cord Dysfunction
Paradoxical vocal cord movement when breathing can obstruct airways. An ENT can evaluate vocal cord function.
Laryngopharyngeal Reflux
Stomach acid backing up into the throat can irritate the larynx and trigger coughs. An ENT can assess for reflux and damage to the throat.
Lung Conditions
An ENT may order imaging or lung function tests to check for underlying lung diseases contributing to chronic cough.
When to See an Allergist
Allergies like pollen or dust mite sensitivity can cause postnasal drip and coughing. Consulting an allergist may help if:
- Symptoms worsen in certain seasons
- You have other allergy symptoms like sneezing, itchy eyes, or runny nose
- Over-the-counter allergy meds haven’t helped
Allergy testing can identify specific triggers. Allergen immunotherapy like shots can treat severe respiratory allergies.
When to See a Pulmonologist
A pulmonologist specializes in lung conditions if coughing persists despite treatment. They may order tests like:
- Chest x-ray
- CT scan
- Sputum culture
- Lung function tests
FAQs
Is coughing up mucus normal when laughing?
It's common to occasionally cough up small amounts of mucus when laughing hard. But regularly hacking up colored phlegm or large volumes of mucus when laughing is not normal.
What causes someone to cough up mucus every time they laugh?
Frequent mucus production when laughing can be caused by untreated allergies, asthma, sinus infections, lung diseases, or gastroesophageal reflux disease (GERD).
When should you worry about coughing up mucus when you laugh?
See a doctor if you cough up blood, experience shortness of breath, have a persistent cough lasting over 3 weeks, or cough up colored phlegm on a regular basis.
How can you stop coughing up mucus when you laugh?
Try increasing fluids, using a humidifier, irrigating nasal passages, taking expectorants, using cough drops, and quitting smoking. Seek treatment for any underlying conditions.
What lung problems can cause someone to cough up mucus when laughing?
Lung conditions like chronic bronchitis, pneumonia, COPD, pulmonary fibrosis, and lung cancer can all lead to increased mucus production and coughing spells when laughing.
