Many Canadian kids woke up to the smell of wildfire smoke last summer. Some are wondering：Is it dangerous? How can I protect myself? The host talked to two children’s lung(肺) experts，Tom Kovesi and Dan Hughes，to find out how kids can stay safe.
Is wildfire smoke dangerous?
For most people，the effect(影响) of wildfire smoke is only short - term. Effects can include irritation(刺激) of the eyes，nose and throat，coughing and shortness of breath. They will get worse the more time you spend outdoors，especially if you’re active outside—doing sports and other exercise.

“The difference between campfire smoke and wildfire smoke is that wildfire smoke is harder to avoid，” Hughes said. “When you’re camping，you typically don’t stay in front of a fire for too long，” he said. “And if it’s really smoky，you’d probably sit upwind from the smoke or take a break.” Wildfire smoke，on the other hand，is everywhere. Therefore，the effects can be more long - term and dangerous.
The key to staying safe? Stay inside.
Both Kovesi and Hughes agree that the best thing for kids to do is stay inside when wildfire smoke is in the air.
“It’s especially important for kids who are super active to stop those activities. This is not the time to go jogging，play soccer or other sports，” Hughes said. “Those activities require you to breathe harder and deeper，which gives you a greater exposure(暴露) to the smoke and the particles(微粒) the smoke carries.”
Other steps you can take.
It’s best to close your windows and doors when inside. You can also use an air conditioner(空调)，if you have one，to filter(过滤) the air more. Kovesi said that masks can also help lower the risk a little，particularly N95 masks. But they need to be worn correctly.
