Wildfire smoke is pushing more Oregonians into emergency rooms than usual, and the patients showing up are younger than health officials expected. Adults ages 18 to 44 make up the largest share of people seeking care for respiratory complaints in smoke-blanketed regions, according to the Oregon Health Authority (OHA), which reported the trend on August 5, 2026. This pattern has caught experts off guard, since older adults and people with chronic illnesses are typically assumed to be most vulnerable.

Why Are Younger Adults Getting Sicker From Smoke?

The answer may come down to risk perception and behavior. Gabriela Goldfarb, environmental health manager for OHA's Public Health Division, explained the disconnect: younger adults may feel less vulnerable to air quality threats and are less likely to take precautions, even though smoke affects everyone's health. Meanwhile, older adults and those with existing conditions like asthma or COPD (chronic obstructive pulmonary disease) are already taking protective steps, which may be keeping them out of emergency departments.

"Folks who are in that younger cohort may feel a little bit less vulnerable. But it turns out it impacts everybody's health as well," said Gabriela Goldfarb, environmental health manager for OHA's Public Health Division.

The smoke itself is the culprit. When trees and plants burn, they release tiny particles called PM2.5, which are about 30 times thinner than a human hair. These particles are small enough to sink deep into the lungs and pass directly into the bloodstream, where they can trigger inflammation and breathing problems.

Who Is Most at Risk From Wildfire Smoke?

While the emergency room data shows younger adults seeking care, certain groups face higher risk from smoke exposure. People with heart disease, asthma, COPD, or diabetes are especially vulnerable, as are children whose respiratory systems are still developing. The common symptoms of smoke exposure include burning eyes, coughing, and a sore throat. Anyone experiencing painful or difficult breathing, or whose pre-existing health conditions worsen, should seek medical advice immediately.

As of early August 2026, much of Oregon sits under an air quality advisory, including Portland and long stretches of central and eastern parts of the state. Nationally, the situation is even more dire: crews are fighting 86 uncontained large fires, roughly half of them in Oregon and Washington, according to the National Interagency Fire Center. Firefighters have responded to over 45,000 wildfires so far this year, burning more than 5.5 million acres.

How to Protect Your Lungs During Poor Air Quality

• Stay Indoors: When air quality turns unhealthy, remain inside and skip strenuous outdoor activities like running or heavy yard work. If you lack air conditioning, spend part of the day in a library, community center, or other public building with filtered air.
• Use Proper Filtration: Indoors, portable HEPA (high-efficiency particulate air) units can reduce smoke particles. A do-it-yourself version can be rigged from a box fan and furnace filters. Outdoors, only a snug N95 or KN95 respirator will block smoke particles; bandanas, cloth face coverings, and surgical masks let particles slip through.
• Monitor Your Symptoms: Watch for burning eyes, coughing, and sore throat. Seek medical attention if you experience painful or difficult breathing, or if your existing respiratory or heart conditions worsen during smoke events.

Smoke in the Portland area was expected to thin by Friday, August 8, 2026, and across eastern Oregon by Saturday, August 9, 2026, according to the OHA. However, as long as wildfire season continues, smoke events will remain a recurring threat to respiratory health across the West.

The takeaway for younger adults is clear: feeling invulnerable to air quality threats can be dangerous. Smoke does not discriminate by age, and taking precautions now can prevent an unnecessary trip to the emergency room later.
