What are the types of cough humidifier can handle?

Although humidifiers can help relieve cough, it doesn’t always work for all types of cough. Hence, you must know the kind of cough that you have first. Here are some coughs that a humidifier can handle. Also, despite using a humidifier it is still important that you get appropriate medical treatment for your cough. 

  • Wet Cough: This type of cough is so named because it is typically associated with the secretion of watery mucus. This is caused by cold or flu and is your body’s way of pushing out excess mucus from your respiratory tract. This type of cough occurs more commonly at night although you can occasionally have fits of cough during the day as well. 
  • Dry cough: dry cough is not accompanied by the production of mucus hence the name. It is often in response to a trigger but can also be as a result of inflammation of some section of your respiratory tracts such as the larynx, bronchi or even your throat. The dry cough usually occurs at the end of a bout of cold or at night time. It can also be due to allergies, asthma, sore throat among other causes. Sometimes, dry cough comes with severe or mild pain due to the dryness as well as some hacking noise in your throat. 
  • Paroxysmal Cough: this is a more severe case of cough. Paroxysmal cough is also known as whooping cough and can be life-threatening if left untreated. It can be accompanied by a struggle to breathe and vomiting in some case. Bear in mind that using a humidifier is not equivalent to treatment for this kind of cough. Hence, babies need to be vaccinated to prevent paroxysmal cough and you should speak to a doctor to avoid fatality. 
  • Croup cough: This type of cough is caused by a viral infection in children between ages 1 to 5. The infection causes the airways to swell up thereby making it harder for air to pass. Children or adults suffering from this type of cough often have difficulty breathing and they make some sound as they do so. The cough is barky and may leave you with a raspy voice for days.
