When exposed to smoke many kids (and adults) with asthma will get extra breathing treatments to open up their lungs, according to the guidelines. Here's a different approach to smoke and asthma treatment

When the wildfires hit Northern California, I knew it would be only a matter of time before the smoke drifted into the Bay Area and the air quality worsened. Predictably, children with asthma would be showing up in emergency rooms and urgent care centers to get breathing treatments for their increased wheezing.

And three weeks later there would be an increase in cases of pneumonia and lower respiratory tract infections.

Non-COVID respiratory conditions are more important than ever! Find out why ...

Smoke and Asthma Treatment

Let's address why humans wheeze in the first place. Wheezing is an adaptive, protective mechanism. It's a cool feature of the human body. When we encounter something toxic in the air (historically, most often smoke from fires, but now also toxic fumes from chemicals) the muscles around breathing tubes tighten to decrease air flow to the delicate tissues of the lung. Mucus production in the breathing tubes increases to trap particles on the way in. The lining becomes inflamed to destroy those particles. All of this combines to narrow the caliber of the breathing tubes and create the wheezing sound you hear.

Normal wheezing protects the lungs. Asthma is what we call it when people wheeze repeatedly when they don't need to for protection.

When the smoke arrives, many kids with asthma will be getting extra breathing treatments to open up their lungs, according to the guidelines. But it's great to avoid that if practical!

Treating Kids with Asthma Exposed to Poor Air Quality

Wouldn't it be better if kids with asthma avoided exposure?

Stay home from school while the air quality was at its worst

Stay indoors with an air filter on if possible.

Don't exercise during brief episodes of poor air quality

Enjoy a game or movie day instead (and, of course, keep up with homework!)

I've seen it work. We protected kids' lungs from increased exposure to harsh toxins and none of them needed extra breathing treatments. And they weren't part of the observed spike in infections afterward.

There is another way.

Simple and powerful. Working with the body, not against it.

Be well,
