How do you sleep with a blocked nose?

Nasal congestion often seems to get worse at night. Congestion, also known as a stuffy nose, is fluid buildup in the tissue lining the nasal passages. This narrows the upper airway, making it difficult to inhale and exhale through your nose.

Part of the reason congestion may feel worse at is night is that you might be too distracted during the day to notice how stuffy you really are. But that's not the whole story. There are a few other factors that contribute to increased stuffiness at night.

This article discusses the different causes of congestion at night. It also provides tips for easing nighttime stuffiness.

Reasons Behind Nighttime Congestion

Stuffiness is caused by excess mucus blocking the nasal passageways. Another culprit is swollen and/or inflamed blood vessels inside the nasal passages. Both of these issues can be worse at night.

Nighttime congestion is sometimes a matter of human anatomy and gravity. With some health conditions, lying down makes symptoms worse. Many people notice that congestion starts to improve an hour or two after they get up in the morning. That's often gravity doing its work once again.

Anatomy and Congestion

When you are standing or sitting upright during the day, mucus is constantly draining naturally due to the force of gravity. It makes its way from your nose and sinuses into the back of your throat, where it is swallowed. You likely don't even notice it's happening.

However, when you are in bed or reclining in a horizontal position, gravity can cause mucus to pool or back up instead of drain.

Blood Flow Changes

When you lie down, your blood pressure changes. And blood flow to the upper part of your body can increase, including the blood flow to your head and nasal passageways.

This increased blood flow can inflame the vessels inside your nose and nasal passages, which can cause or worsen congestion.

Natural alterations in blood flow due to pregnancy is also a common cause of congestion.

Alternate-Side Nasal Congestion

Many people find that one nostril is clogged at certain times of the day, but the congestion switches sides at night.

If only one nostril is clogged at night, it is likely due to alternate-side nasal congestion. This is due to a normal process known as the nasal cycle. The reason for the cycle is unknown, but it is not a disorder.

The congestion occurs when a turbinate (a structure along the sinus wall that produces mucus) becomes swollen in one nostril. This blocks airflow on that side.

Acid Reflux

Gastroesophageal reflux disease (GERD) is a condition that causes stomach acid to flow back up into the esophagus, the tube that connects your mouth to your stomach.

Known as reflux, it occurs when the sphincter between the stomach and esophagus (esophageal sphincter) is weak and unable to stay closed. Acid reflux can cause nasal irritation that can lead to congestion.

People with GERD can experience acid reflux at any time of day. And hen you lie down and lose the help of gravity, stomach acid is even more likely to come up the esophagus.

This is why GERD symptoms, including nasal congestion, sore throat, coughing, postnasal drip, wheezing, and hoarseness, tend to be worse at night and first thing in the morning.

Recap

Acid reflux due to GERD can cause nasal congestion. Reflux symptoms tend to get worse at night when you lie down. As a result, your nose may become more congested at night.

Reducing Nighttime Congestion

Studies show that nasal congestion at night can have a big impact on sleep quality. In fact, people with chronic sinusitis are three to nine times more likely to experience sleep disturbances with frequent nighttime awakenings.

Try these tips to help reduce nighttime congestion and sleep better:

• Elevate the head of your bed instead of lying flat.
• Don't eat within a few hours before going to bed or lying down.
• Use a cool-mist humidifier at the side of your bed.
• Drink plenty of water throughout the day.
• Stop smoking.

If a medical condition is causing your stuffiness, your healthcare provider may recommend additional strategies and medications to ease your symptoms and help you sleep.

For example, allergies can be treated with antihistamines, nasal steroids, or immunotherapy. Medications such as antacids and proton pump inhibitors are commonly used to treat GERD.

Summary

You're not imagining that your nasal congestion gets worse at night. There are a few different reasons you could be experiencing this, and more than one may be at play.

Some, like your sleep position, can be easily fixed. Others, like GERD, may need medical treatment.

Your healthcare provider can determine the cause of your nighttime congestion, so you can get restful sleep.

Frequently Asked Questions

• Can nasal congestion cause sleep problems?

  Yes. Having congestion, a stuffy nose, and other nasal symptoms increase the likelihood that you'll have obstructive sleep apnea, a disorder in which you repeatedly stop breathing while you sleep. Sleep apnea can increase your risk for other health problems such as diabetes, depression,and heart failure.

• Is having a stuffy nose related to snoring?

  Yes. Mouth breathing is a common cause of snoring, and when you have nasal congestion, youre more likely to resort to mouth breathing, so a stuffy nose can eventually lead to snoring. The opposite is also true: researchers have found that people who snore are more likely to have nasal symptoms. This may be because snoring causes inflammation that leads to nasal problems.

• Whats the best way to unblock your nose at night?

  Rinse out your nose with a saline solution using an irrigation device such as a neti pot, which has been shown to improve nasal symptoms. Raising your head using pillows can also help your sinuses to drain and prevent some congestion.
