Quick answer

For a stuffy nose, everyday relief often comes from humid room air, steam inhalation, saline nasal rinses, drinking enough fluids, and sleeping with the head slightly raised. Vitamin C and zinc contribute to the normal function of the immune system. Persistent symptoms should be checked out by a doctor.

A blocked nose is a nuisance: breathing is difficult, your sense of smell fades, and at night you can barely find rest. Usually a harmless cold is behind it, but allergies or dry heated air can also be the reason. The good news is that with simple home remedies you can often achieve noticeable relief.

What lies behind a blocked nose

When the nose is blocked, it is rarely down to too much mucus alone. Responsible above all is a swelling of the nasal mucous membranes. The fine blood vessels in the nose widen, the tissue fills with blood, swells and narrows the airways - much like a swollen cushion makes the airway narrower. The trigger is often a viral cold, in which the immune system reacts to the pathogens and boosts the blood flow to the mucous membrane.

Other causes are also possible: allergies such as hay fever lead, via an excessive reaction of the immune system, to swollen, itchy mucous membranes; dry room air draws moisture from the nose and irritates it; and some people react sensitively to dust, animal hair, smoke or strong smells. More rarely, anatomical peculiarities such as a deviated nasal septum or nasal polyps are behind it, causing permanently obstructed nasal breathing. The excessive use of decongestant nasal sprays can also irritate the mucous membrane over time and even worsen the congestion - experts then speak of a habituation effect, in which the nose swells shut all the more without the spray.

When you should see a doctor

A cold-related blocked nose usually improves on its own within one to two weeks. You should seek medical advice if the complaints last longer than about ten days to two weeks or worsen, if high fever or severe head or facial pain is added, or if the nasal mucus is purulent yellow-green and one-sided. Also with recurring sinus infections, bloody discharge, permanently obstructed nasal breathing, pronounced allergic complaints, or if you need decongestant nasal sprays for longer than a week, an assessment is sensible. With infants and small children who have breathing problems and, for example, have to audibly gasp for air while drinking, you should seek medical advice early. These notes apply regardless of any home remedies you use yourself.

What you can do day to day

Moisture is your best ally. Inhalations with warm water vapour, for example over a bowl of hot (not boiling) water with a towel over your head, are experienced by many as soothing for the nose; the warm vapour moistens the mucous membrane and makes stuck mucus more supple. Nasal rinses with an isotonic salt solution flush out mucus, crusts, dust and irritants and moisten the mucous membrane. Ready-made salt sprays or a nasal douche from the pharmacy are practical here and can be used several times a day.

Ensure moist room air, especially during the heating season, for example with a humidifier, damp cloths on the radiator or a bowl of water. Still air out regularly with short bursts, so that dry heated air and irritants can get out. Drink enough, because sufficient fluid helps to keep the mucus thin so that it drains better. At night a slightly raised head end, for example with a second pillow, can make breathing easier, because the blood does not pool so strongly in the head. A warm bath or a warm shower before bed works similarly to a small inhalation. Fresh air and exercise outdoors are also felt to be pleasant by many. Refrain from using decongestant nasal sprays for longer than a few days, to avoid a habituation effect.

Telling a cold and an allergy apart

Whether a cold or an allergy is behind the blocked nose makes a difference for the right everyday measures. A cold usually builds up over one to two days, often comes with a scratchy throat, fatigue and mucus that is initially clear and later thicker, and subsides again after about a week. An allergic runny nose, on the other hand, often occurs suddenly and in particular situations - for example during pollen season outdoors, on contact with animals, or in the evening in bed with a house dust allergy. Typical are a watery runny nose, fits of sneezing and itchy, watering eyes, while fever is absent.

Anyone who suspects an allergy takes care in everyday life to avoid the triggering substances as far as possible: pollen screens on the window, washing your hair in the evening, changing out of daytime clothes before the bedroom, and regular wiping against dust can reduce the burden. With allergies too, nasal rinses with salt solution do many people good, because they flush pollen and dust out of the nose. Recurring or pronounced allergic complaints belong in a medical assessment, so that the triggers can be determined.

Nutrition that supports

With a cold in particular, a light, nutrient-rich diet is sensible. Warm soups and broths are traditionally valued because the warmth and the rising steam are felt to be soothing and at the same time provide fluid and a little salt. Rely on plenty of vegetables and fruit to supply your immune system with vitamins and secondary plant compounds.

Hot spices such as ginger, chilli, mustard or horseradish are experienced by many as briefly clearing for the nose, because their pungency makes the mucous membranes run for a short while. Warm herbal teas, for example with chamomile, thyme, sage, elderflower or peppermint, provide fluid and soothing steam. Citrus fruits, peppers, berries and cabbage vegetables provide plenty of vitamin C; nuts and wholegrains contribute zinc. Overall, aim for a balanced, vitamin-rich diet that supplies your body well during this time, and drink enough spread across the day.

Nutrients & plants with a connection

Some nutrients have a recognised connection to the immune system and the mucous membranes. Vitamin C contributes to the normal function of the immune system, also during and after intense physical exercise. Zinc contributes to the normal function of the immune system and to the maintenance of normal mucous membranes. Vitamin A contributes to the maintenance of normal mucous membranes and to the normal function of the immune system. Vitamin D also contributes to the normal function of the immune system. Mucous membranes in particular form the frontline barrier of the airways, which is why their maintenance is especially relevant in connection with the nose.

From the plant world, essential oils from eucalyptus, peppermint, spruce needle and thyme are traditionally valued for a feeling of free breathing, for example as an additive in inhalations or as a balm on the chest. Chamomile and sage have a long tradition of use for irritations of the upper airways. Important: with small children and infants, some essential oils such as menthol and camphor are unsuitable. These plants and nutrients do not replace medical treatment, but can be a consciously chosen part of your everyday life.

An honest perspective

A cold-related blocked nose usually heals on its own, and home remedies such as inhalation, nasal rinsing and moist air aim to make the time until then more pleasant and to ease breathing. No nutrient and no plant clears a swollen mucous membrane permanently at the push of a button. Be critical of remedies that promise a quick cure. The most important principle is: plenty of moisture, a little patience, and a medical assessment if the complaints do not subside, keep recurring, or run an unusual course.

Frequently asked questions (FAQ)

Why is the nose blocked with a cold?

Because the nasal mucous membranes swell. The immune system reacts to the viruses, the blood vessels in the nose widen and the tissue swells, which narrows the airways.

Does a nasal rinse with salt water help?

Many people find nasal rinses with an isotonic salt solution pleasant, because they flush out mucus and irritants and moisten the mucous membrane. Use ready-made solutions or a nasal douche from the pharmacy for this.

How long may I use decongestant nasal spray?

Decongestant nasal sprays should only be used for a few days, as a rule not longer than a week. With prolonged use, the mucous membrane can get used to it and swell permanently.

Which nutrients support the immune system?

According to EU health claims, vitamin C, vitamin D, vitamin A and zinc, among others, contribute to the normal function of the immune system. Zinc and vitamin A additionally support the maintenance of normal mucous membranes.

Does moist room air really help?

Dry air, especially during the heating season, additionally irritates the nasal mucous membrane. Moister room air from a humidifier or a bowl of water on the radiator is felt by many to be more pleasant for the airways.

What can I do against a blocked nose at night?

A slightly raised head end, a nasal rinse before bed, moist room air and drinking enough across the day are felt by many to be helpful for breathing more easily through the nose at night.

When should I see a doctor?

If the complaints last longer than about ten to fourteen days, worsen, come with high fever, severe facial pain or one-sided purulent mucus, or if nasal breathing is permanently obstructed.
