Why You Need a Humidifier If You Have Asthma

Asthma isn’t a condition you can necessarily control, but you can make the likelihood of an asthma attack a bit less likely. Asthma can be triggered by several things, including exposure to allergens, respiratory infections, strong fragrances, or cigarette smoke.

But did you know that too little humidity can also trigger an asthma attack? If there isn’t enough humidity in the air, your body will overproduce mucus, which can then either trigger an asthma attack or make an existing attack even worse.

There are thousands of humidifiers on the market, but the best air humidifiers for asthma will meet several specific standards. Think carefully about who the unit is for. The best air humidifier for asthma sufferers who are very young will likely be different from the best air humidifier for an elderly person. You also need to think about whether air purification and measurements of humidity levels are important features you want your humidifier to have.

Think carefully about the space you want to humidify, too. For instance, do you need to cover an entire home or just one individual room? There are plenty of options to choose from, so narrowing down your list of desired specifications before you even start shopping can be a major help.
