Dealing with a Blocked Nostril? Here’s How to Clear It Fast! (2024)

Have you ever been frustrated by one side of your nose feeling completely blocked while the other is clear? As annoying as it is, this is a common congestion pattern that can make sleep, breathing and even concentrating feel difficult. Especially during cold and flu season, one blocked nostril can be frustrating. So what can you do about it? To find out, we asked health experts why this happens, simple remedies to clear congestion and when it might be time to see a doctor.

Is it normal to have just one blocked nostril?

Yes, having one blocked nostril is quite common. This is often due to something called the “nasal cycle.” According to Andrew Youssouf, MD, Medical Director at Ikon Recovery, this is “a natural process where each nostril takes turns being more open, which alternates every few hours.”

This helps keep our noses from drying out and also supports better breathing by giving each side a bit of rest. However, during illness or allergy flare-ups, this natural nasal congestion can become more intense and noticeable.

What causes one clogged nostril?

A single blocked nostril can be caused by a variety of factors beyond the nasal cycle. “A stuffy nose on one side usually happens when you’re dealing with the common cold, allergies or a sinus infection, which can cause swelling and mucus to clog things up,” explains Raj Dasgupta, MD, Chief Medical Advisor for Fortune Recommends.”

Cold and flu infections can cause inflammation and mucus buildup, while allergens like dust, pollen and pet dander can lead to swelling. Sinusitis, an infection of the sinuses, can lead to lasting congestion, particularly in one nostril.

“If one side stays blocked consistently, it could be due to a deviated septum (when the wall between nostrils is uneven) or nasal polyps, noncancerous growths that can restrict airflow,” adds Dr. Youssouf.

Home remedies to relieve a blocked nostril

If you’re experiencing discomfort due to a single blocked nostril, Dr. Dasgupta and Dr. Youssouf share some effective home remedies to help open up your airways.

1. Try steam inhalation

“Breathing in steam from a hot shower or a bowl of hot water can help reduce inflammation and loosen up mucus,” says Dr. Youssouf. Fill a bowl with hot (not boiling) water, lean over it with a towel draped over your head and breathe in the steam for about five to 10 minutes.

2. Use a humidifier

Dry air can make congestion worse, especially during the colder months when heating systems dry out indoor air. “Adding moisture to the air keeps nasal passages from drying out, which can reduce congestion,” says Dr. Youssouf. Aim for a humidity level of around 40 to 50 percent for optimal comfort. (You can measure your home’s humidity using an inexpensive hygrometer.)

3. Try a nasal saline spray

“Using a saline rinse or spray, like a neti pot, can wash out any buildup,” says Dr. Dasgupta. Saline moisturizes the nasal passages, reducing irritation and thinning mucus for easier removal. Using saline several times a day can provide relief and prevent further congestion.

If you use an over-the-counter nasal decongestant spray, Dr. Youssouf recommends limiting it to three to four days. “Using it longer can make congestion worse (known as rebound congestion),” he adds.

4. Use a warm compress

“A warm compress on your nose might relieve some swelling,” says Dr. Dasgupta. The heat reduces inflammation and promotes better circulation, which can help reduce congestion in the blocked nostril. Soak a washcloth in warm water, wring it out and gently place it over your nose and forehead for a few minutes.

5. Elevate your head when sleeping

“Propping up your head when you sleep encourages drainage and can reduce congestion,” says Dr. Youssouf. By propping yourself up with an extra pillow, you can improve airflow and reduce the feeling of one blocked nostril. Sleeping on one side may also help reduce swelling and ease drainage.

6. Stay hydrated

As with many illnesses, drinking enough fluids is crucial to prevent dehydration. “Drinking water helps thin mucus, making it easier to drain,” adds Dr. Youssouf.

When to see a doctor for a blocked nostril

While having one blocked nostril is usually due to temporary congestion, there are times when it may be a sign of an underlying issue that needs medical attention. “If the blockage doesn’t ease up after a few weeks, or if you have pain, headaches or trouble breathing, it’s a good idea to check in with a doctor,” advises Dr. Dasgupta. “They might look for things like a deviated septum or polyps and could suggest nasal sprays, allergy meds or possibly surgery if it’s a more serious blockage.”

“Chronic sinusitis or allergies could also be to blame, and treatments for these include decongestants, steroid nasal sprays, antihistamines or even allergy shots, depending on what is causing the issue,” adds Dr. Youssouf.
