The winter heating season often results in a troublesome dry cough due to the drastic drop in humidity in homes. Dry mucous membranes become susceptible to irritation. Learn about the causes of this problem and effective solutions: from humidifiers and nebulisation to home remedies and tips on when to seek medical attention.
Why does dry cough occur during the heating season?
In winter, intense heating drastically reduces the humidity levels in homes, often below the recommended 40%. This decrease leads to dryness of the mucous membranes, especially in the respiratory tract, which is the direct cause of the agonising dry cough. Weakened and dried out mucous membranes become much more susceptible to irritation. As a result, they react much more easily to common factors such as dust, mites or allergens. A dry cough is the body’s natural defence reflex in an attempt to rid itself of these unwanted stimuli.
When is a humidifier an effective solution to a cough?
A dry cough is often a direct result of too low a humidity level, which falls below 40% during the heating season. The most effective solution to this problem is a humidifier, which restores the optimum humidity level of 40-60%, thus eliminating the main cause of the ailment. Proper humidification provides the mucous membranes with adequate hydration, crucial after irritation and drying by heating. This relief effectively relieves discomfort and significantly reduces the agonising cough reflex. Different types of devices are available on the market, making it easy to tailor equipment to individual needs. There are evaporative, ultrasonic and vapour models.
How do I use a humidifier safely and effectively?
In order for a humidifier to operate safely and effectively, it is essential to constantly control the humidity level. A humidistat (built-in or external), which effectively prevents the air from becoming too saturated with steam, is crucial. It is absolutely essential to clean the equipment regularly. This is the only way to prevent the growth of bacteria and mould. The microorganisms sprayed in the room significantly aggravate the condition of our respiratory tract. Remember that only distilled water should be used in ultrasonic models, which eliminates the risk of mineral deposits. Also, for proper circulation, don’t forget to ventilate the room regularly.
When to choose nebulisation instead of a humidifier for a dry cough?
When to use nebulisation instead of a humidifier? It is essential when the dry cough is a symptom of acute inflammation. This requires intensive and targeted local action, especially in the case of laryngitis and the accompanying acute, ‘barking’ cough. By delivering a cool mist of medication straight to the irritated mucous membranes, the nebuliser ensures that the active ingredient reaches the mucous membranes quickly, deeply and precisely, providing immediate relief from acute complaints. The humidifier, on the other hand, only has a general effect on the room environment. It does not have any healing properties or local therapeutic effect.
What preparations can be used in a nebuliser for dry cough?
For a dry cough, isotonic saline solution (0.9% NaCl) is the basic and safest nebulisation agent. It effectively moisturises the respiratory tract mucosa, relieving persistent irritation. Relief can be enhanced with preparations with hyaluronic acid (better hydration and barrier protection). Remember: do not nebulise essential oils or herbal infusions – they risk irritating the lungs and damaging the device.

What home remedies can help treat a dry cough?
To effectively relieve a dry cough at home, intensive hydration is key. Regularly drinking warm beverages keeps the mucous membranes moist, relieving throat irritation. Invaluable relief is provided by honey. Thanks to its coating and soothing effect, taking a teaspoonful is recommended, especially just before bedtime, to minimise night-time coughing. Traditional syrups, such as those made from onions or pine shoots, are also useful. Lozenges containing mucilaginous substances such as horsyplasia, lichen or plantain provide temporary relief. These natural ingredients form a protective layer over the irritated membrane that moisturises and soothes, effectively reducing the bothersome cough reflex.
When does a dry cough require consultation with a doctor?
If natural methods (moisturising, honey) do not bring relief, the duration of the cough should be monitored. Medical consultation is necessary when a subacute cough lasts longer than three weeks. On the other hand, a chronic cough – lasting more than eight weeks – already requires an in-depth diagnosis. It is important to seek help immediately when alarm signals appear. These include shortness of breath, high temperature, chest pain and expectoration of coloured, distressing secretions. A persistent cough often signals a more serious condition, such as asthma, COPD or gastro-oesophageal reflux. A specialist will determine the root cause by selecting targeted therapy. In addition to medication for the underlying disease, he or she may prescribe antitussives such as butamirate, codeine or dextromethorphan.
FAQ
1.Are there contraindications to the use of inhalants?
Yes, contraindications to inhalation include purulent inflammation, haemorrhages, respiratory tumours and severe circulatory or respiratory failure.
2.What are the main types of nebulisers and how do they differ?
There are piston (compressor) inhalers, which are versatile and can administer most medications, and mesh (MESH) inhalers, which are quieter, portable and ideal for travel, producing an aerosol by squeezing the solution through a mesh.
3.How does dry air affect the spread of viruses?
Dry air creates very good conditions for viruses to grow, increasing the risk of infection in rooms with low humidity.
4.Can warming ointments be used for a persistent dry cough?
Yes, warming ointments work very well in persistent dry cough and can provide relief.
