Sometimes, it may also be due to inflammation of the wall of the respiratory tract (bronchi, throat and larnx).

In most cases, it often comes with a mild to severe pain because of the dryness and its mostly caused by the upper respiratory infections.

Inhaled medicine has always been a very effective way of treating throat infections like cough and bronchitis. Different humidifiers have different ways of working, but all of them contribute immensely to the increment of the humidity level of a room.

When someone is coughing, it’s the body response to the irritation of the airways caused by dryness. Either a cool or warm mist will fill the space with enough moisture so that the person can inhale a wet air into the respiratory tract to ease the tickling behind the throat.

The center for disease control and prevention suggest that humidifier can soothe coughing by loosening the mucus, but there wasn’t clear enough evidence to support the use of either the cool mist or the warm mist.

Conclusively, dry air could be a cause of coughing and can also be a bad combo with coughing. A humidifier will go a long way to help add moisture to the air. Warm mist humidifier may help in soothing but endeavor to choose cool mist for babies because of burns.
