Coughing is actually a protective reflex of our body that helps clear out irritants and secretions in the respiratory system. When it comes to sleep, one crucial thing to note is that our body’s protective mechanisms may function differently than when we’re awake. You might be surprised to learn that, indeed, it’s possible to cough in your sleep, although it’s generally not as common as when we’re awake. This is mainly because our body’s reflex functions tend to be suppressed during sleep, specifically in the deeper stages.

Now that we’ve established that coughing in your sleep is a possibility, it’s essential to dig deeper and understand the intricacies that govern this body response. In the following sections of this article, I’ll address potential causes behind nighttime coughing, its impact on overall sleep quality, and ways to manage this troublesome issue. So, let’s dive in and shed light on this fascinating topic.

Understanding Sleep Coughing

Ever wondered if it’s possible to cough in your sleep? Let’s explore the science behind sleep coughing and gain a better understanding of this phenomenon.

Coughing during sleep isn’t as common as you might think. Most people don’t cough while they’re asleep, primarily because our cough reflex is suppressed during sleep. Our brain shifts its focus to essential things like maintaining our vital organs and going through different sleep stages. But sometimes, you may still experience sleep coughing, particularly if you have an underlying health condition.

A few common causes of sleep coughing include:

  • Asthma: This chronic lung condition can lead to coughing during sleep due to airway inflammation and narrowing.
  • Gastroesophageal reflux disease (GERD): Stomach acid can flow back into the esophagus, irritating the throat and causing coughing.
  • Chronic bronchitis: Long-term inflammation of the bronchial tubes can cause excessive mucus production and coughing.
  • Allergies: Exposure to allergens like dust mites, pet dander, and pollen can all contribute to nighttime coughing.

If you’re concerned about sleep coughing, it’s essential to consult with a healthcare professional. They can help assess your symptoms, identify the cause, and prescribe an appropriate course of treatment.

For example, if your symptoms are caused by asthma, your doctor might recommend an inhaled corticosteroid to help with inflammation. If GERD is the culprit, they could suggest lifestyle changes or medications to reduce acid production.

Of course, not all sleep coughing warrants medical intervention. If you’re dealing with a temporary ailment like the common cold, some self-care strategies can help alleviate your symptoms:

  • Keep your head elevated to help reduce mucus buildup in your throat.
  • Use a humidifier to add moisture to the air, making it easier to breathe.
  • Drink plenty of fluids to help thin mucus and stay hydrated.
  • Avoid irritants like cigarette smoke and pollution that can worsen coughing.

In conclusion, coughing during sleep isn’t impossible, but it’s relatively rare because the cough reflex is suppressed during this time. However, if sleep coughing persists or worsens, it’s crucial to seek medical advice, as it could indicate an underlying health condition or illness.

Causes of Coughing During Sleep

Coughing during sleep can be a troublesome experience. It’s important to identify the potential causes to get a better understanding of this condition and find the most appropriate solution. Among the most common reasons are allergiesacid refluxinfections, and sleep apnea.

  • Allergies: Exposure to allergens such as dust mites, pet dander, or pollen can irritate the airways, resulting in coughing. Allergic reactions can cause excess mucus production, which accumulates in the throat and triggers a reflexive cough. To minimize the impact of allergens, it’s essential to keep the sleeping environment clean and well-ventilated.
  • Acid reflux: Gastroesophageal reflux disease (GERD), commonly referred to as acid reflux, can also cause coughing during sleep. When stomach acid backs up into the esophagus, it leads to irritation in the esophagus lining, and in turn, causes a cough. GERD symptoms may worsen while lying down, so it’s crucial to adjust sleeping positions and consider dietary changes to alleviate discomfort.
  • Infections: Respiratory infections, such as the common cold or flu, may lead to coughing during sleep. Postnasal drip, which is a symptom of upper respiratory infections, triggers coughing when mucus drains from the nasal passages down the back of the throat. Treatment for such infections typically involves rest, hydration, and over-the-counter medications.
  • Sleep apnea: Obstructive sleep apnea (OSA) is characterized by pauses in breathing during sleep due to partial or complete obstructions in the airway. These obstructions can result in airflow limitation, leading to a protective coughing reflex to open the airway. OSA diagnosis and management requires consultation with a sleep specialist, and treatment options include lifestyle modifications, continuous positive airway pressure (CPAP) therapy, or surgery.

In addition to these common causes, certain medications and lifestyle factors (such as smoking) might contribute to nighttime coughing. Assessing your specific situation is crucial for identifying the root cause of this bothersome symptom. Once determined, you’ll be better equipped to take the necessary steps to alleviate coughing during sleep and improve your overall quality of life.

Nighttime Cough Remedies

If you’re struggling with coughing during the night, it’s essential to find effective remedies that can help ease the cough and lead to a restful night’s sleep. Here I’ll discuss some helpful nighttime cough remedies that can make a significant difference in finding relief.

Stay hydrated: Drinking plenty of water throughout the day is crucial for overall health, but it’s also helpful in thinning mucus, reducing congestion, and ultimately, easing the cough. Opt for warm liquids such as tea with honey, or clear broth to soothe your throat before bedtime.

Humidify the air: Using a humidifier can increase the moisture in the air, which can help alleviate dry coughs. Dry air tends to irritate our nasal passages and throat and might exacerbate nighttime coughing. If you don’t have a humidifier, taking a steamy shower before bed or placing a bowl of hot water in the room can have a similar effect.

Elevate your sleeping position: Sleeping with an elevated head can help reduce coughing while you sleep. Prop up your head with extra pillows or, if possible, try an adjustable bed to prevent mucus from pooling at the back of the throat.

Avoid allergens and irritants: Dust, pet hair, and cigarette smoke can irritate the throat and lungs and lead to coughing. Keep your bedroom clean, using hypoallergenic bedding and air filters to reduce exposure to allergens. Additionally, avoid smoking and being exposed to secondhand smoke.

Take over-the-counter (OTC) medications: Several OTC medications can help ease coughing. Cough suppressants, such as dextromethorphan, can provide temporary relief. Antihistamines and nasal decongestants may also reduce coughing due to allergies or congestion.

Here are some helpful tips for relieving a nighttime cough:

  • Drink warm liquids throughout the day and before bedtime
  • Use a humidifier or similar method to moisten the air
  • Elevate your head during sleep
  • Keep your bedroom clean and hypoallergenic
  • Consider OTC medications for temporary relief

Finding the right combination of remedies that work for you is essential to getting a good night’s sleep. Keep in mind, if your cough is persistent, severe, or accompanied by other concerning symptoms, it’s important to consult with a healthcare professional for proper evaluation and treatment.


Can you cough in your sleep? The answer is yes, but it’s quite rare. After exploring the many factors contributing to a nocturnal cough, it’s crucial to consider potential health risks and treatments, especially for sleep enthusiasts committed to obtaining a good night’s rest. The following key takeaways emerged from our analysis:

  • The brain typically suppresses involuntary actions like coughing during sleep to avoid disrupting the sleep cycle.
  • Sleep apnea, acid reflux, and respiratory conditions may influence the likelihood of coughing during sleep. Proper treatment can help reduce symptoms, and with it, the chance of nighttime coughing.
  • Practicing good sleep hygiene and seeking professional help when necessary can promote better sleep and reduce the risks associated with coughing during sleep.

For those seeking to improve their sleep quality, it’s important to maintain healthy habits and pay attention to any indicators of sleep disturbances. While it’s uncommon to cough during sleep, addressing potential underlying causes may save not only your rest but also your overall health. Ultimately, it’s important to remember that having a consistent, undisturbed night’s sleep contributes significantly to your well-being, and being proactive in resolving sleep issues is essential.
