A chronic cough is a cough that lasts 8 weeks or longer in adults (or 4 weeks or longer in children). It may be caused by conditions such as acid reflux, allergies, asthma, or irritable larynx syndrome (ILS), which can make the voice box overly sensitive. Treatment may include medical care, lifestyle changes, and speech therapy to help reduce coughing and protect your voice.
Key takeaways
A cough is considered chronic if it lasts 8 weeks or longer in adults (or 4 weeks or longer in children).
Chronic cough is often caused by conditions like acid reflux, allergies, asthma, medications, or irritable larynx syndrome (ILS).
If you feel an urge to cough when talking, laughing, or breathing cold air, your voice box may be overly sensitive.
Speech therapy can help retrain the cough reflex, reduce throat irritation, and teach techniques to suppress the urge to cough.
If your cough lasts several weeks or keeps returning, talk with your doctor to determine the underlying cause.

Get startedWhy do we cough?
Coughing is an important protective reflex that starts in your larynx, or “voice box.” When something irritates your throat or airway, nerves send a message to your brain, which quickly triggers a cough to help clear the irritation.
An occasional cough is completely normal. Your throat and airway contain specialized nerves that constantly monitor for things that shouldn't be there, such as dust, smoke, or mucus. Coughing helps keep your lungs healthy.
“Most coughs go away once the irritation is gone. But when coughing lasts for weeks or months, it's often a sign that something else is continuing to irritate the airway,” says Alexis Irazoque, M.S., L/SLP, a licensed speech therapist with Expressable.
What causes chronic cough?
A cough is considered chronic if it lasts eight weeks or longer. This length of time makes it less likely that your cough is caused by a respiratory infection or common cold.
A chronic cough can be annoying, uncomfortable, and socially isolating. It can significantly impact your quality of life and cause damage to your voice if not treated.
Many different conditions can lead to a chronic cough. Here are some of the most common:
Lung diseases: Conditions such as asthma, chronic obstructive pulmonary disease (COPD), and pulmonary fibrosis can all cause persistent coughing. These conditions are typically managed by your primary care provider or a pulmonologist.
Allergies: Seasonal allergies or allergies to things like pollen, mold, pet dander, or dust mites can irritate your airway and trigger coughing. You may also notice sneezing, itchy eyes, congestion, or a runny nose.
Acid reflux: Gastroesophageal reflux disease (GERD) occurs when stomach acid flows back up through the tube connecting your mouth and stomach (the esophagus). It sometimes even flows up into the throat, which leads to chronic cough and may cause voice problems. This condition may be managed with simple lifestyle and dietary changes, depending on the root cause.
Acid reflux can cause throat pain, voice changes, and difficulty swallowing. Learn more about these symptoms and how to heal your voice.
Medications: Certain medications, such as ACE inhibitors, are known to cause chronic cough in a small percentage of people. If you suspect a medication may be causing side effects, work with your doctor to see if there might be a better medication for you. Always speak with your doctor before stopping any prescribed medications.
Smoking: Cigarette smoke and vaping expose your airway to chemicals that irritate the throat and lungs, often leading to persistent coughing and inflammation.
Long COVID: Some people continue coughing for weeks or months after recovering from COVID-19. A chronic cough may occur alongside fatigue, shortness of breath, or changes in voice. Talk with your doctor about ways to overcome this chronic condition.
Speech therapy can treat long-term COVID symptoms that affect your voice and speech, such as throat pain, brain fog, and problems with word finding.
Irritable larynx syndrome (ILS): In ILS, the nerves in the voice box become overly sensitive after repeated irritation. This can lead to chronic coughing, throat clearing, and breathing symptoms that are triggered by things like talking, cold air, strong smells, or stress.
This is not an exhaustive list, but the conditions above are commonly associated with chronic cough. In order to get an accurate diagnosis and treatment plan, work with your primary care doctor. They may refer you to one of the following specialists:
Allergist
Ear, nose, and throat (ENT) specialist
Pulmonologist
Gastroenterologist
Winter weather can affect your voice. Learn how to take care of your vocal health in the winter and during cold and flu season.
What is irritable larynx syndrome?
Your larynx contains delicate tissues and nerves that help you breathe, swallow, and speak. Normally, these nerves protect your airway by triggering a cough only when something harmful enters your throat.
With irritable larynx syndrome (ILS), those nerves become hyperresponsive. They begin reacting to everyday sensations that normally wouldn't cause a problem. As a result, even mild triggers can create a strong urge to cough, clear your throat, or tighten the muscles around your voice box.
Think of ILS like a mosquito bite. Scratching it feels good for a few seconds, but it ultimately makes the itch worse. In the same way, coughing or throat clearing may briefly relieve irritation, but over time they make the nerves in the voice box even more sensitive.
Many people with ILS notice that once symptoms begin, they seem to feed into one another. Repeated coughing or throat clearing causes more irritation, which makes the nerves even more sensitive over time.
Depending on which nerves and muscles are affected, ILS can cause a variety of symptoms.
Symptoms of irritable larynx syndrome
Symptoms of irritable larynx syndrome can include chronic coughing, frequent throat clearing, a lump-in-the-throat sensation, throat tightness, difficulty breathing in, or episodes where the throat suddenly feels like it's closing.
Symptoms vary from person to person, but common signs include:
Frequent throat clearing or a constant urge to clear your throat
A lump-in-the-throat sensation (called globus)
Burning, tickling, or irritation in the throat
Tightness in the throat or neck
Pain or extra effort when swallowing
Difficulty breathing in due to paradoxical vocal fold motion
Episodes of laryngospasm (when the vocal cords briefly close and make it feel difficult to breathe)
Causes of irritable larynx syndrome
Irritable larynx syndrome develops when repeated irritation makes the nerves in the voice box overly sensitive. Several different irritants can start this cycle, and many people have more than one trigger. Common causes include:
A respiratory infection that caused lingering coughing
Acid reflux (GERD or LPR)
Postnasal drip
Seasonal or environmental allergies
Cigarette smoke or secondhand smoke
Strong odors, such as perfume or hairspray
Food sensitivities
Cleaning products or harsh chemicals
Cold air or very hot, humid air
Stress, anxiety, or strong emotions
Excess tension in the muscles used for speaking
How is irritable larynx syndrome treated?
Treatment begins by identifying what's irritating your larynx and addressing those triggers whenever possible. For example, if acid reflux is contributing to your symptoms, your doctor may recommend medications, dietary changes, lifestyle modifications, or other strategies to reduce reflux and protect your throat.
Many people also benefit from speech therapy. A speech-language pathologist, also known as a speech therapist, can help you:
Understand why your cough or throat clearing continues
Improve vocal hygiene to reduce irritation
Relax tight muscles around your voice box
Improve how your larynx moves during breathing and speaking
Learn cough suppression and throat-clearing replacement strategies
Retrain your nervous system so everyday sensations are less likely to trigger coughing
In some cases, your doctor may recommend additional medical treatments, including medications that help calm overly sensitive nerve pathways when appropriate.
“Many people think coughing or throat clearing is helping their throat, but it often has the opposite effect,” Irazoque adds. “Repeated coughing can keep the larynx irritated and make the cough reflex even more sensitive.” Speech therapy helps break that cycle by teaching practical strategies to calm the larynx and reduce the urge to cough.
Why do I cough when I talk or laugh?
Talking, laughing, and singing all require your vocal cords to move rapidly. If your larynx is already irritated or overly sensitive, that normal movement can activate the cough reflex.
This often happens in people with laryngeal hypersensitivity. The hypersensitivity itself may develop because of conditions such as reflux, allergies, asthma, upper respiratory infections, muscle tension dysphonia, paradoxical vocal fold movement, or irritable larynx syndrome.
If you cough when you talk, you may also notice:
An urge to cough when laughing, singing, or exercising
Coughing while eating or drinking
Frequent throat clearing
Hoarseness or changes in your voice
A feeling that something is stuck in your throat
Throat irritation or burning
What helps a chronic cough?
There's no one-size-fits-all treatment for chronic cough. Whether your cough is caused by allergies, reflux, asthma, irritable larynx syndrome, or another condition, managing the underlying cause is the most important step toward lasting relief.
At the same time, taking care of your throat and voice can help reduce irritation while your body heals. Irazoque suggests several strategies that may help.
Stay hydrated. Water helps keep the tissues of your throat and vocal cords moist, making them less likely to become irritated. Staying hydrated may also reduce the dry, tickling sensation that often triggers coughing. Aim to drink water consistently throughout the day instead of waiting until you feel thirsty.
Treat dry mouth or dry throat. Dry tissues become irritated more easily. If your mouth or throat feels dry, try:
Using a humidifier, especially while sleeping
Breathing through your nose instead of your mouth
Taking a warm shower or inhaling steam
Sucking on lozenges that promote saliva production, such as those containing slippery elm, manuka honey, or fennel
If you take medications that cause dry mouth, ask your doctor whether other options may be available. Address underlying medical conditions. A chronic cough is often a symptom of another condition. If allergies, asthma, acid reflux, or another medical issue is causing your cough, treating that condition is often the most effective way to find relief. Your doctor can help determine whether medications, dietary changes, allergy management, or other treatments are appropriate.
Expert tips for vocal hygiene. Learn how to take care of your voice, how to prevent voice problems, and when voice therapy might help.
Avoid your triggers. Many people notice that certain environments or activities make their cough worse. Common triggers include:
Cigarette smoke or secondhand smoke
Perfumes or scented products
Cleaning chemicals
Dust, mold, or pollen
Cold air
Dry indoor air
Keeping track of when your cough happens can help you identify personal triggers to avoid whenever possible.
Protect your voice. Repeated coughing places significant stress on your vocal cords. To help protect your voice, do your best to:
Avoid yelling or speaking over loud background noise.
Rest your voice when you're sick.
Limit unnecessary throat clearing.
Continue drinking plenty of water throughout the day.
If your cough continues despite these strategies (or lasts more than eight weeks), talk with your doctor. They can help identify the underlying cause and determine whether additional treatment, including speech therapy, may be helpful.
Find the right speech therapist for you
We'll match you with a speech therapist who's experienced in your area of need and available when you are.
Get startedHow a speech-language pathologist can help chronic cough
Many people are surprised to learn that speech therapy can be an effective treatment for chronic cough.
Rather than treating the lungs themselves, speech therapy focuses on the larynx (voice box) and the sensitive nerves and muscles that control coughing, breathing, and speaking. This approach is especially helpful for people whose cough continues despite treatment for conditions like asthma, allergies, or reflux.
Your speech-language pathologist will begin by learning about your symptoms, medical history, and the situations that trigger your coughing. From there, they'll create a treatment plan that's tailored to your specific needs. This might include:
Retraining your cough reflex
One goal of speech therapy is to make your cough reflex less sensitive. Your therapist will teach you behavioral cough suppression techniques that help you manage the urge to cough before it happens. Depending on your needs, these strategies may include:
Gentle nasal inhalation
Relaxed diaphragmatic (belly) breathing
Swallowing instead of coughing
Taking small sips of water
Relaxed exhalation through pursed lips
With regular practice, many people find that these techniques become more natural and that coughing occurs less often.
Reducing irritation in your voice box
Every cough creates forceful contact between your vocal cords. Over time, that repeated impact can increase irritation and make the cough cycle harder to break.
Your speech therapist will help you reduce unnecessary strain on your voice by teaching healthy breathing patterns, improving how your larynx functions during speaking and breathing, and reducing excess muscle tension around your voice box.
They'll also recommend vocal hygiene strategies to keep your vocal cords healthy, such as staying hydrated, managing reflux when appropriate, minimizing throat clearing, and avoiding environmental irritants.
Building long-term control
As you learn to recognize your personal triggers and practice new breathing and cough suppression strategies, you'll build skills that help you manage symptoms more confidently in everyday life.
Research shows that many people notice meaningful improvements in cough frequency and severity within several weeks of beginning speech therapy, particularly when it's combined with treatment for the underlying medical condition.

Frequently asked questions (FAQs)
There isn't a permanent cure for irritable larynx syndrome, but it is highly treatable and manageable. Many people experience significant improvement once the underlying source of irritation is identified and treated. Treatment often includes speech therapy, respiratory retraining and cough suppression techniques, avoiding triggers (e.g., cigarette smoke), and practicing good vocal hygiene.
A tickle in your throat usually means that something is irritating your upper airway. That irritation activates the cough reflex to help protect your lungs. Common causes include reflux, allergies, postnasal drip, asthma, dehydration, harsh chemicals, and can even occur as a side effect of certain medications.
Yes. Speech therapy is an evidence-based treatment for many types of chronic cough. Rather than simply treating the cough itself, an SLP helps reduce the sensitivity of the cough reflex and teaches you strategies to prevent coughing before it starts. Your speech therapist may help you learn how to suppress the urge to cough, manage throat tickles without throat clearing, improve breathing patterns, reduce muscle tension around the voice box, and protect your vocal cords with healthy voice habits.
In adults, a cough is considered chronic if it lasts 8 weeks or longer. In children, a cough is considered chronic if it lasts 4 weeks or longer. If your cough has continued beyond these timeframes, it's important to see your doctor.
Yes. Repeated coughing places significant force on your vocal cords and can lead to ongoing irritation or injury. Over time, chronic coughing may cause swelling and inflammation, hoarseness (or other voice changes), vocal cord nodules, polyps, or cysts, frequent throat clearing, and increased sensitivity of the voice box. This creates a cycle in which coughing causes irritation, and the irritation triggers even more coughing. Seeking treatment early can help protect your voice and reduce the risk of long-term vocal cord damage.
You should schedule an appointment with your healthcare provider if your cough:
Lasts more than 8 weeks (or 4 weeks in children)
Keeps coming back without a clear cause
Causes hoarseness that doesn't improve
Makes it difficult to breathe, sleep, or communicate
Occurs with coughing up blood, chest pain, unexplained weight loss, or persistent fever
Your doctor can determine what's causing your cough and refer you to the appropriate specialist, such as an ear, nose, and throat (ENT) physician, pulmonologist, gastroenterologist, allergist, or speech-language pathologist.
