Warm or cool Mist humidifier for bronchitis?

The principal function of a humidifier is to increase the level of humidity in the air. There are two main types of humidifiers. A warm mist humidifier comes with a heating element that heats water creating steam that is dispersed into the room increasing the moisture level. A cool-mist humidifier releases water into a wick and then a fan breaks the liquid into small droplets expelling the vapor into the air and cooling the room.

The warm mist humidifier makes breathing more comfortable when you are in a cold
Environment, which is perfect for patients with bronchitis. Steaming is a significant therapeutic measure for dealing with bronchitis, and the warm mist is the closest humidifier method that releases steam. You do want to be careful when using the warm mist humidifier due to its heating element that can be a potential burn hazard.

The cool mist humidifier is also almost as effective as the warm mist because it helps in relieving cough and moisturizes a dry nose. It is also much safer and covers a larger area than the warm mist humidifier.

While a warm mist humidifier is more effective, the cool mist humidifier provides better features, benefits, and safer operating conditions. If you do buy a warm mist humidifier, make sure to use it carefully.

What does a humidifier do for a cough?

The answer is quite simple. A humidifier, whether warm or cold, uses water to produce a mist that is released into the atmosphere soothing your cough when you inhale it. It increases the level of humidity in the atmosphere getting rid of illnesses and dryness in the air that can irritate you and cause you to cough.

By increasing the humidity level of the room space, your throat and nasal passages are moisturized easing your breathing and reducing mucus secretions. Coughs that are due to irritated mucous walls will be soothed by the continuous moisture in the air.

Can a humidifier make a cough worse?

Yes, it can. But it will all depend on how you use the humidifier. The primary purpose of the humidifier is to increase the moisture level in the atmosphere. This device should be used moderately and under specific conditions to ensure its effectiveness. If a humidifier is used incorrectly, you can possibly make your cough worse.

Before you use a humidifier, make sure the humidity level in the air is really low like in the wintertime or on a cold night. During the summer, humidity levels are naturally high, so if you add more moisture to the air, you can cause an increase in bacterial growth in the air, furniture, or walls, which can also cause an asthmatic reaction.

When you inhale bacteria in the air, you can increase symptoms like a cough or even cause new symptoms to develop. When using a humidifier, make sure you are careful and clean it regularly to avoid mold growth and air contamination. Also, always use distilled water to prevent white dust from minerals in the water to form, which can also cause you to cough.

How does a humidifier help bronchitis?

Bronchitis is the inflammation of the bronchial tubes, which leads to the release of a higher amount of mucus than normal. When you use either a cold or warm mist humidifier, you put moisture into the air while you breathe helping to clear the excess amount of mucus.

By lubricating your throat and nasal discharge passage, humidifiers help you breathe easier and more comfortably. With a high level of moisture, you will see less swelling and more healing.

Qualities to consider when purchasing the best humidifier for chronic bronchitis

  • Size:

When it comes to humidifiers, the size of the machine correlates to the area that it can cover effectively. You should purchase a humidifier that will be able to release enough mist to soothe your cough no matter where you are in the room. The manufacturer should provide the area that the machine will effectively work in, but you can always do extra research to make sure it will work for the room you intend to use it in.

  • Type of mist:

While a warm mist humidifier is most effective in soothing a cough, a cool-mist humidifier is known to be just as effective as a warm mist humidifier and is advised to be the best purchase for safety reasons. Warm mist humidifiers have been responsible for a high amount of burns each year, especially in children, due to the use of a heating element. Cool mist humidifiers are safer overall and also come with the same features and benefits of a warm mist humidifier.

  • Humidistat:

Humidistats automatically monitor the humidity level in the atmosphere and then adjust it accordingly. When humidity levels are high, the device will turn off. Once the humidity level drops to a certain preset point, the machine will kick in again working to raise the humidity level again by adding add more moisture into the air.

  • Safety features:

You will find many humidifiers with safety features like auto shut down and tip-over protection. These handy features help with ease of use and for added peace of mind.

  • Timer function:

A timer function allows you to set your humidifier to suitable working hours. For example, you can set the humidifier to start just before you wake up or an hour before you get home from work. This allows the air in your home to be ready for you whenever you need it.

  • Aromatherapy:

Devices with this function allow you to add essential oils that have an aroma and medicinal values that relieve coughs. This aroma is released along with the mist and, when it is inhaled, it reduces inflammation in your bronchial cords allowing you to breathe easier.
