What are the main causes of sinus problems?

Sinus problems usually occur when the air passages in the nose get inflamed for a long time.  According to the Center for Disease Control (CDC), this problem is mostly caused by a virus and bacterial infections. These affect the lining of the sinuses, making them swell. Additionally, research also points out dry air among the main causes of sinus problems. Dry air makes the mucus membrane dehydrate and swell. The swelling blocks the airways, causing congestion, which leads to sinus problems or even infections. 

Can humidity cause sinus problems?

Yes. Low humidity makes the nasal membrane dry out. This allows mucus to clog, paving the way for bacteria to grow into the sinuses. When the bacteria gets into the sinuses, they make the mucus membrane get inflamed. After which, an individual will start feeling nasal congestion and pain. In the same way, high humidity increases the amount of mucus in the nose. This leads to congestion, thus causing sinus problems.

Do humidifiers help with sinus issues?

Yes, humidifiers help with sinus issues. Humidifiers add moisture to the air you breathe. This helps relieve nasal congestion and allows free airflow. Therefore, you will have better breathing and reduction of any side effects caused by sinus problems. 

What type of humidifier is best for sinus problems?

Choosing the best humidifier can be challenging as there are numerous types on the market. However, The type of humidifier should not be a problem in your quest of dealing with sinus problems. Various types of humidifiers use different processes to produce mist, but the results are the same. So, you only have to choose a humidifier that makes you comfortable. The commonly used types of humidifiers are cool and warm-mist. 

Warm mist humidifiers boil the water and release vapor into the air. These humidifiers prevent the aeration of bacteria and are quiet. But, warm-mist humidifiers consume more energy and can be dangerous if left within the children’s reach.

On the other hand, cool mist humidifiers use fans to evaporate water into the air. These are safer, energy efficient and do not pose any immediate risks like accidental burns that could arise from hot water. Because cool mist humidifiers use fans, they are louder. Moreover, cool mist humidifiers without filters can release contaminants into the air. So, if you choose cool-mist humidifiers ensure you always use distilled water to avoid releasing pollutants into the air. 

Otherwise, any of the above humidifiers will help you with your sinus problems.

How can I pick the best humidifier for sinus problems?

  • Area coverage. You need to ensure the humidifier you choose matches with the space it will be used in. A humidifier with large area coverage may quickly humidify a smaller room. And if you are not monitoring the humidity levels, it may lead to excessive moisture being produced which will then favor mold and bacteria growth. Conversely, a humidifier with less area coverage may take longer to humidify a larger room and thus will not help to quickly relieve any sinus problems.
  • Humidistat. you should pick a humidifier with a built-in humidistat. This will help you regulate the mist output and humidity being produced to ensure it does not become too low or too much. Low humidity will aggravate sinus symptoms. In the same way, high humidity can lead to the growth of mold which causes fungal sinusitis. So, you need to ensure the humidifier can effectively balance humidity to create a safe environment.
  • Easy to clean. Choose a humidifier that can easily be cleaned. Models that are hard to clean create a gap for bacteria growth and piling up of white dust.
