A subacute cough typically lasts for 3 to 8 weeks, with common causes consisting of post-infectious cough, postnatal drip, and eosinophilic bronchitis. Finally, chronic cough is the most severe type of cough, and it can last longer than eight weeks. Some common triggers for coughs are Asthma, smoking, bacteria, viruses, allergies, and environmental factors.
Can a Humidifier Alleviate Cough?
Humidifiers help relieve cough and discomfort by releasing moisture into the air. The increased humidity will moisten the dry nasal passages and removes excess mucus for easier breathing. While they are not a magic cure for all kinds of cough, these appliances help alleviate discomfort and lessen the severity of cough-related symptoms.
A humidifier is also helpful in reducing inflammation, nasal congestion and prevent cough from spreading to other people. In addition, it can help alleviate seasonal allergies and Chronic Obstructive Pulmonary diseases such as chronic bronchitis and emphysema in the long run.
Things to Consider While Buying a Humidifier
Mist type: Most of the humidifiers generate either warm or cold mist.
A warm mist humidifier releases moisture into the air by heating water and can help cure cold and flu symptoms. Warm mist humidifiers produce minimal noise since the steam comes out of the unit without the aid of a fan. However, one of the primary drawbacks of the warm mist humidifier is that it consumes more energy as it uses electricity to boil water draws power. Moreover, warm mist humidifiers are not recommended for use around children or pets since the boiling water, along with the steam the unit emits, may be hazardous if a child gets too close or knocks it over.
Cool mist humidifiers consume less electricity as they do not modify the water temperature before dispersing it to the atmosphere. Cool mist humidifiers mostly employ ultrasonic or evaporative technology to circulate cool soothing air throughout the house environment. In addition, as per the Food and Drug Administration, a cool-mist humidifier can help shrink swelling in nasal passages.
Run Time: The run time denotes the amount of time the humidifier can disperse mist before running out of water in the tank. If you wish to operate the humidifier through the night, it would be ideal for running at least 10 hours straight.
Noise level: Every humidifier makes some noise, regardless of how quiet it is advertised to be. If you have a bedroom model, it needs to be very quiet not to disturb your sleep. In general, the larger the unit, the noisier it is.
Essential oil usage: Besides their wonderful smell, essential oil helps you relax after a stressful day. If you have an interest in essential oils, consider a humidifier with an essential oil diffuser. This will help you save space and money.
Ease of cleaning and refilling: Before purchasing a humidifier for cough, consider how easy or difficult it is to clean and refill. This is because there is a need to continually clean humidifiers meant to resolve cough issues or make them worse.
Water tank capacity: Larger the tank’s size, the more mist you’ll be able to disperse into a larger area for an extended amount of time. Also, a larger tank would not require frequent refilling making it more convenient.
Ease of Setup: If you suffer from a cough, you will loathe spending hours setting up the humidifier. Most modern humidifiers have a straightforward setup process, where you need to open the machine and plug the device, and it’s ready to help you from cough.

FAQ
When to Change the Humidifier filter?
Evaporative humidifiers come with built-in filters that need to be periodically replaced as per the manufacturer’s specifications. For example, some units require filters to be replaced every season while others give more specific timeframes, like six months or one year.
How often should you change water in the humidifier?
If you are suffering from a cough, it is ideal to replace the water in the humidifier every day. Please only use distilled water in the machine to prevent calcium build-up in the water chambers and help avoid dirty water infections.
Use a clean cloth and wipe the components of the machine that is exposed to water. Use natural disinfectants such as vinegar to remove stubborn mineral deposits such as mold. Always rinse the water tank before changing water and give the unit a thorough clean once a week.
Can Humidifier Worsen Cough?
While a well-maintained humidifier will not give you a cough, a poorly maintained, a dirty humidifier may adversely impact your health. Some people have been known to suffer from “humidifier fever” by inhaling vapors contaminated with allergens such as mold, fungi, bacteria, viruses that may aggravate cough and other illness symptoms.
Do not overuse the humidifier. Using a humidifier in conditions where humidity exceeds 50% may worsen asthma and promote the growth of microorganisms. Some humidifiers allow you to manually alter the conditions for the humidifier, while some units come with an auto sensor. You can also purchase a hygrometer to monitor the home humidity level and use the machine when the humidity level falls below 30%.
