Humidifiers can help ease a cough, and people can use them alongside other treatment options for optimal benefit.

A humidifier is a device that adds moisture to the air to increase humidity levels in a room or home.

It raises the level of moisture in the air, which can help ease dryness and irritation in various parts of the body, including the skin, throat, and nasal passages.

Humidifiers can often help ease congestion and coughs.

They come with several advantages:

  • Consistent humidity: Humidifiers provide a consistent level of humidity, which helps maintain moisture in the respiratory tract.
  • Versatility: People can use humidifiers in various settings, such as bedrooms, living rooms, and offices. These devices come in different types to suit varying preferences and needs. Some offer different models, such as cool mist, warm mist, and ultrasonic.
  • Complementary to other treatments: People can use humidifiers alongside other therapies, such as saline nasal sprays, hydration, and steam inhalation, for comprehensive relief.

Adding moisture to the air

Dry air can make the mucus in the nasal passages and throat thick and sticky, making it harder to expel. Humidifiers add moisture to the air, which helps thin the mucus, making it easier to cough up or blow out.

The moisture from a humidifier can soothe dry and irritated tissues in the nose and throat. This is especially beneficial if someone has a dry and hacking cough.

Easing breathing

Moist air can help reduce inflammation in the airways, making breathing more comfortable and reducing the urge to cough.

A humidifier can make breathing easier by maintaining a comfortable level of humidity, which is particularly helpful during sleep and can reduce nighttime coughing.

Preventing dryness

Dry air can dry out the nasal passages, leading to discomfort and congestion. Humidifiers keep these passages moist, which can help reduce congestion.

Moist air prevents the formation of dry crusts in the nose, which can block nasal passages and cause discomfort.

Using a humidifier effectively can significantly help ease a cough.

There are two main types of humidifier:

  • Cool mist humidifiers: These are generally safe and effective for children and adults and do not pose a burn risk.
  • Warm mist humidifiers: These can add warmth to the air, which some people find soothing. However, individuals need to use these with caution around children due to the risk of burns.

Some tips to help people use a humidifier include:

  • Location: People can place the humidifier in the room where they spend the most time, such as the bedroom at night or the living area during the day. To ensure an even distribution of moisture, position the humidifier on a table or shelf about 2 to 4 feet off the ground.
  • Clean water: Using distilled or demineralized water can prevent the buildup of minerals and reduce the risk of releasing white dust into the air. Tap water can contain minerals and impurities that may lead to deposits in the humidifier and potential respiratory issues, so people need to avoid this.
  • Humidifier settings: People can aim for an indoor humidity level between 30% and 50% and use a hygrometer to monitor it. Depending on the severity of the cough and the dryness of the air, the humidifier may need to run continuously or for several hours, especially at night.

Regular maintenance and cleaning

People need to empty and rinse a humidifier’s water tank daily to prevent the growth of mold, bacteria, and other pathogens.

Additionally, a solution of white vinegar or a manufacturer-recommended cleaner can thoroughly clean the humidifier once a week.

If the humidifier has filters, people need to replace them as the manufacturer recommends to ensure optimal performance.

Additional tips

  • Positioning: The humidifier should not be directly next to the bed or where people sit, as this can cause overexposure to moisture. Keep it at a comfortable distance.
  • Ventilation: While using the humidifier, ensure there is some ventilation in the room to prevent excess moisture buildup, which can lead to mold growth.
  • Monitor symptoms: Pay attention to how the body responds. If the cough worsens or there are signs of mold or mildew, people need to stop using the humidifier and consult a healthcare professional.

Following these steps and tips, a humidifier can help ease a cough and improve respiratory comfort.

Not all humidifiers are suitable for use with essential oils. Ultrasonic humidifiers with a designated essential oil tray are suitable, but oil can damage traditional evaporative and warm mist humidifiers.

Using humidifiers compatible with essential oils can provide several benefits, such as:

  • Aromatherapy: Essential oils can provide a pleasant fragrance and promote relaxation, reduce stress, improve mood, and enhance sleep.
  • Therapeutic effects: Certain essential oils have properties that can help relieve symptoms of colds, congestion, and respiratory issues. For example, eucalyptus and peppermint oils can help open airways and reduce coughing.
  • Air freshening: Essential oils can help mask unpleasant odors and create a more pleasant indoor environment.

People need to contact a doctor if they experience:

Infants, young children, elderly, or immunocompromised people with coughs also need to seek medical attention.

When in doubt, a person needs to consult a healthcare professional to ensure proper evaluation and treatment.

By maintaining optimal humidity levels, humidifiers can create a more comfortable living environment, especially in dry climates or during winter months when indoor air can become particularly dry.

They can help ease symptoms of colds, flu, and allergies by keeping airways moist.
