What Is Sleep Apnea and How Can a Humidifier Help?

What Is Sleep Apnea and How Can a Humidifier Help?Sleep apnea is a sleep disorder that causes someone’s breathing during their sleep to stop and start repeatedly. Multiple people who suffer from the condition end up snoring. Those who have this condition will not rest properly and will feel tired despite sleeping for the right amount of time. Sleep apnea can have three main types, respectively central sleep apnea, obstructive sleep apnea, and complex sleep apnea syndrome.

Usually, dry air in the room can worsen the symptoms of the condition as it keeps the respiratory tract dry as well. But with a humidifier, this can change.

Humidifiers add moisture to a room’s air, which will ensure that the nasal passages will not be dry. When you have a dry respiratory tract, you will not breathe properly, especially if the air is dry too. But humidifiers will help prevent dryness in your throat and nose. They will add moisture into the air, which will allow you to breathe properly and get better sleep.

Warm Mist vs. Cool Mist: Which Is Better for Sleep Apnea?

When it comes to choosing the best humidifier for sleep apnea, you have two options – warm mist and cool mist humidifiers. You have to choose the best depending on the causes of your sleep apnea.

Warm mist humidifiers are great options for people who want to improve their sleep quality because they are much quieter. They will also reduce the number of bacteria in your home’s air. This is important if you’re suffering from any allergy, which causes sleep apnea in return.

Additionally, with warm mist humidifiers, you can add medicated aromas in a special tray. That being said, it will be much easier to have a good night’s sleep after adding some soothing aromas.

On the other hand, there are cool mist humidifiers that are also amazing, especially during summer. They can not only humidify the air but also decrease the temperature for better sleep during the warm season. However, unlike warm mist humidifiers, they don’t do a great job at killing bacteria, which makes them a little less fitting for people with sleep apnea.

There’s no such thing as the best humidifier that is a magical device for sleep apnea – there are only humidifiers that are good for your particular needs. Some people may have a more severe sleep apnea compared to others, and, as a result, they may need more features in a humidifier. Here’s how to pick your best humidifier for sleep apnea if you want to improve your sleep:

  • Noiseless Operation

Noisy units are annoying, that’s for sure. It’s not enough that your sleep apnea prevents you from sleeping – purchasing a noisy humidifier will make it even worse. This is why humidifiers with a noiseless operation are a blessing for people who suffer from the condition. Warm mist humidifiers, in particular, have no fans, which makes them less noisy and more fitting when you want a device to run quietly.

However, you can find cool mist ones that were designed to run more quietly as well. You can check out the product specifications and find out how noisy the unit is before purchasing it.

  • Portability

It’s great to be able to move your humidifier around, particularly if you want to cover as much of the house and room as possible. Smaller tanks are more portable, but larger humidifiers are more efficient. So, it’s important to look for a product that comes with a carrying handle so that you can move it with ease and make sure your air has the right humidity level.

  • Adjustable Humidity Level

Since dry air can worsen your sleep apnea, you have to choose a product that properly humidifies the air and helps your respiratory tract. The product you end up selecting would be a much better choice if it has adjustable humidity levels because you can always customize your own experience and create the perfect conditions.

  • Auto Shut-Off System

Auto shut-off systems are great for those units that run while you sleep. They will keep the device safe ensuring it will not be damaged if it runs out of water.


People have some questions regarding humidifiers for sleep apnea, and rightfully so. Here are the most commonly asked ones:

  • Can you sleep with a humidifier for sleep apnea on?

Yes, you can. Since you have sleep apnea, humidity needs to be maintained the most during the night, when the condition is affecting you. As such, leaving the device on while you sleep is highly recommended. You just have to make sure that you get a quiet humidifier.

It can also be safe as long as the product you buy has an auto shut-off feature.

  • Will a humidifier completely cure my sleep apnea?

Humidifiers can’t completely cure sleep apnea, but they can increase your comfort as they ease your symptoms. These devices are often used as part of sleep apnea therapy, so they can be very helpful when you want to prevent a dry respiratory tract.

  • What should I put in my humidifier for sleep apnea?

You may consider adding humidifier tablets into the tank or add some white vinegar. These will help with preventing mold from growing, as mold can be very harmful to inhale, considering it worsens respiratory conditions.


Humidifiers can be a great way to make sure you get to have a good night’s sleep when sleep apnea bothers you. This is why you need the best humidifier for sleep apnea. Having said that, we hope we were able to help you pick a suitable model.
