A blocked nose without a runny nose

A blocked nose does not always mean that there is a large amount of mucus in the nasal passages. The sensation of blockage may be caused primarily by swelling of the mucous membrane or by a narrowing of the space through which air flows. In the 19th century, many factors were described that could potentially block the sinus passages, and today we know that a blocked nose without obvious nasal discharge can have allergic, irritant, anatomical, hormonal or even drug-induced causes.

Swelling of the nasal mucosa and allergies

One of the most common causes of obstruction of airflow through the upper respiratory tract is swelling of the nasal mucosa. The tissues inside the nose are highly vascularised and can swell in response to various stimuli; this is why the nose may feel completely blocked despite the absence of visible discharge. This occurs, amongst other things, in allergic rhinitis. Exposure to pollen, house dust mites, animal dander or other allergens can trigger swelling, sneezing, an itchy nose and reduced nasal patency. However, a runny nose does not necessarily occur in every person with these symptoms, nor with every flare-up of the allergy.

Non-allergic rhinitis, spicy foods and alcohol

Non-allergic rhinitis can cause similar symptoms. In this case, the symptoms do not result from a reaction to a specific allergen, but may occur following exposure to tobacco smoke, exhaust fumes, strong odours, aerosols, chemicals, very cold or dry air, or a sudden change in temperature. In some people, nasal congestion is also exacerbated by alcohol or spicy foods. The sensitive mucous membrane then reacts by dilating the blood vessels and swelling, even if mucus production remains low.

Anatomical causes, polyps and an enlarged adenoid

Anatomical causes form a separate group. A deviated nasal septum may cause constant or intermittent difficulty in breathing, often more pronounced on one side. Airflow may also be restricted by nasal polyps, hypertrophy of the turbinates and, particularly in children, an enlarged adenoid. It may be characteristic for congestion to worsen when lying down, as the blood supply to the mucous membrane changes with body position. Persistent unilateral obstruction requires medical assessment.

Excessive use of certain drops and sprays, and other causes

A blocked nose may also result from prolonged use of certain drops and sprays that constrict the blood vessels in the mucous membrane. After a few days of regular use, so-called ‘medication-induced rhinitis’ may develop, in which the blockage returns or becomes more severe once the effect of the preparation wears off. Nasal congestion may also be affected by certain medicines used to treat other health conditions (e.g. erectile dysfunction in men). Medical advice is particularly required if congestion persists for several weeks, is clearly one-sided, or is accompanied by frequent nosebleeds, facial pain, a loss of smell or breathing difficulties during sleep.

Indoor conditions

Indoor conditions may also be a cause. Dry, heavily heated air promotes drying out and irritation of the mucous membrane. A feeling of a "stuffy" nose, a burning sensation, scabs or occasional bleeding may occur, even though there is no typical watery runny nose. Interestingly, nasal congestion is also sometimes linked to hormonal changes. It can occur, for example, during pregnancy, and in some people it also varies depending on their hormonal cycle. Certain medical conditions, including thyroid disorders, may also co-occur with chronic nasal symptoms.

Remedies for a blocked nose without a runny nose

stuffy nose

Saline solution and nasal rinsing

One of the simplest methods is to use a saline solution for the nose. A ready-to-use saline spray can moisturise the mucous membrane and help remove fine particles, allergens and dried secretions. Another option is to rinse the nose with a suitable saline solution. Tap water should not be used for this procedure. It is safer to use sterile or distilled water, or water that has been boiled and left to cool. The irrigation equipment must be washed thoroughly after use and left to dry.

Air humidifiers

If the problem worsens in dry rooms, reducing the dryness of the air may help. However, the humidifier should be cleaned regularly (every 2–3 days) and the water replaced in accordance with the manufacturer’s instructions, as a neglected device can become a source of microorganisms. In damp or very dusty rooms, and in urban areas with heavy traffic, it is worth considering using an air purifier fitted with a HEPA (high-efficiency particulate air) filter. A warm shower can provide temporary relief, as the moist air reduces the feeling of dryness in the mucous membranes.

If an allergy is suspected

If an allergy is suspected, it is important to limit contact with the trigger. During periods of high pollen counts, you should wash your face and hair when you get home, change your clothes and avoid drying your washing outside. If you have a dust mite allergy, it helps to wash your bed linen regularly and minimise the build-up of dust in the bedroom. If congestion occurs after exposure to smoke, perfumes, air fresheners or cleaning products, it is best to limit your exposure to the irritant.

Sleeping position

It is also worth paying attention to your sleeping position. For some people, lying completely flat exacerbates the feeling of congestion, so slightly raising the upper body may reduce symptoms at night. Drinking an adequate amount of fluids helps to maintain proper hydration of the body and mucous membranes, but simply increasing water intake is not a treatment for chronic nasal congestion.

Nor is there any reliable evidence to support the use of essential oils, garlic or other popular home remedies as a way of addressing the cause of nasal congestion. Essential oils should not be applied directly to the nose or inhaled in excessively high concentrations, as they may irritate the mucous membrane. Inhaling steam from a bowl of boiling water is unnecessary and carries a risk of scalding.

"A blocked nose without a runny nose does not necessarily indicate an infection. The problem is often swelling of the mucous membrane caused by allergies, dry air or irritants, and is sometimes due to polyps, a deviated septum or prolonged use of decongestant sprays. If the blockage persists for a long time or mainly affects one side of the nose, it is worth investigating the specific cause.” Anna Zięba – Dietitian

FAQ – Frequently Asked Questions

Why is my nose blocked, even though I don’t have a runny nose?

The feeling of a blocked nose may be caused by swelling of the mucous membrane rather than a build-up of mucus. Possible causes include allergies, dry or cold air, smoke and strong odours, as well as anatomical issues.

Can a blocked nose without a runny nose be a symptom of an allergy?

Yes. Allergic rhinitis can cause swelling of the mucous membrane and blockage. A runny nose does not necessarily occur with every flare-up of an allergy.

Why does the nose become blocked particularly at night?

Lying down can alter blood flow to the mucous membrane and exacerbate the feeling of blockage. For some people, slightly raising the upper body whilst sleeping can alleviate the symptoms.

Does saline solution help with a blocked nose?

A saline spray can moisturise the mucous membrane and help remove allergens, pollutants and dried secretions. Appropriately prepared solutions can also be used for nasal irrigation.

Can you rinse your nose with tap water?

You should not use ordinary tap water directly for nasal irrigation. The text recommends using sterile or distilled water, or water that has been boiled and left to cool.

Can nasal decongestant drops and sprays be used for a prolonged period?

Some preparations that constrict the mucous membrane are intended solely for short-term use. Overuse of these can lead to medication-induced rhinitis and recurrent or even more severe congestion.

Can dry air cause a blocked nose?

Yes. Very hot and dry air can dry out and irritate the mucous membrane. In addition to a feeling of blockage, this can lead to a burning sensation, scabs and occasional bleeding.

Is inhaling steam from hot water a good remedy for a blocked nose?

Inhaling steam from a bowl of boiling water is not necessary and carries a risk of scalding. A safer way to relieve the feeling of dryness might be, for example, a warm shower.

When should a blocked nose without a runny nose prompt a visit to the doctor?

A consultation is particularly recommended if the blockage persists for several weeks, is clearly on one side only, or is accompanied by frequent bleeding, facial pain, a loss of smell or breathing difficulties during sleep.
