The humidity of a room determines what types of cough you are suffering from. People use humidifiers to increase the moisture in their room. In contrast, people living in cold areas use dehumidifiers to reduce the humidity level in their rooms.

A dehumidifier is a machine that takes air and separates moisture from this air in your room. People buy dehumidifiers for different benefits, such as – dehumidifiers stopping the breeding of mold, dust mites, and mildew, alleviating allergy symptoms. Dehumidifiers also remove musty odors, prevent water leakage, protect household items, improve respiratory issues, etc.

But the question is – can a dehumidifier cause a cough?

No, a dehumidifier does not cause cough until you misuse it. If you run your dehumidifier continuously when room humidity is 30%, the humidity level will decrease, and dry air will increase in the room. Ultimately, dry air causes a dry cough.

In this article, I will discuss dehumidifiers, humidifiers, humidity, and types of cough related to humidity in-depth. Stick around with me to learn everything you need to know before buying a dehumidifier.

What Causes A Cough?

According to HealthLine, the followings are the causes of cough –

What causes a cough

  • In the room environment, excessive dust, dust mite, pollen, etc., occlude our throat. So, we frequently cough. In high humidity, dust, dust mite, mold exists in the room air. You should reduce the humidity level by using a dehumidifier. In low humidity, pollen and other hypersensitive agents remain in the air. You should use a humidifier to increase the humidity level of your room.
  • In low humidity, bacteria and the virus remain vegetative in the air. They multiply in your respiratory tract and cause respiratory infections. Then you will cough. So, you have to use a humidifier to increase the humidity level up to 40 to 60 percent.
  • A smoker’s cough is caused by smoking with a distinctive sound.
  • If you have asthma, you will fall into the following symptoms – sneezing, wheezing, coughing.
  • Acid reflux means stomach acid causes cough, especially in the night when back up into your throat.
  • Besides, inflammation, sleep apnea, drug side effects are the minor causes of cough.

My advice here is – if you are suffering from cough due to dust mite, mold, mildew, you should pick the right piece of a dehumidifier. I found desiccant dehumidifier is the best dehumidifiers. However, as it produces warm air, you should use a wall-mounted dehumidifier instead. A wall-mounted dehumidifier makes less noise, and warm air will not affect you.

You might be wondering, why am I not right to the point? I have written the causes of cough to save your money from buying a dehumidifier when dust mites, mold, mildew do not cause the cough. Let’s debunk your question.

Can A Dehumidifier Cause A Cough?

No, a dehumidifier does not cause a cough. You should stop it when the room humidity level is the minimum of 40% or 30%. If you run a dehumidifier constantly, this will make your home air dry. Dry air causes a dry cough. So, a dehumidifier can cause a cough when it decreases the humidity below 30%.

What Does A Dehumidifier Do?

A dehumidifier takes water out of the air, decreasing the humidity level. As it is taking out water from the air, your skin gets rid of the sweat into the air. So, you will feel comfortable. In comparison, our body can not expel sweat into the air in high humidity. We feel anxiety and warmth.

A dehumidifier reduces the humidity level to normal if you run it in a damp environment. You will get cured of cough.

Decrement of humidity level to normal is decrement of bacteria, viruses, molds in the air. So, a dehumidifier is good for cough caused by these pathogens.

A dehumidifier also alleviates nasal congestion, harnesses, sore throat, etc. You can breathe better using a dehumidifier in your room.

Why Do Dehumidifiers Make Me Cough?

Why do dehumidifiers make me cough

A dehumidifier pulls your room air into its system. Then it separates the moisture from the air and releases air. A contaminated dehumidifier discharges bacteria, viruses, and mold into the room air during this air releasing time. In our breathing, we inhale these pathogens that give us irritation in the larynx, pharynx, trachea, bronchus and cause coughing.

Humidifier Vs Dehumidifier For Cough

A humidifier is the best choice for cough. For a dry cough, you must use any type of humidifier because it will add moisture to the throat. So, the dry cough will quickly clear up from the throat.

Humidifier vs. dehumidifier for cough

For wet cough (inflammation of the mucous membrane), you should use a cool-mist humidifier. If your humidifier adds more moisture (70/80%) to the air, there will be a convenient environment for growing molds, dust mites. Molds and dust mites cause respiratory issues.

Dry cough is caused by dry air and caused by molds. Mold needs a warm and moist environment to grow. A dehumidifier reduces the humidity of your room, so mold growth becomes retarded. So, if you realize your home has a high moisture level, you should use a dehumidifier.

For COPD (chronic obstructive pulmonary disease), the relative humidity level should be 40% and 70 degrees Fahrenheit. A dehumidifier can adjust the humidity for them, so their airways relax. They will not face coughing or other respiratory symptoms.

People with asthma suffer respiratory issues in high humidity. A dehumidifier can help them by reducing moisture levels. But very dry air makes the condition severe for people with pneumonia, so you should not run your dehumidifier to reduce humidity below 30%.
