A number of wildfires proceed to ravage Los Angeles County, destroying 1000’s of constructions and forcing greater than 130,000 residents to evacuate, with a lot of the world beneath a purple flag warning by means of Friday night time.
Though essentially the most urgent concern is defending our lungs from smoke and ash, wildfires may have an effect on and irritate our sinuses, pores and skin and eyes. Right here’s look after every throughout a wildfire occasion.
Sinuses
Current analysis exhibits that air air pollution and smoke can set off continual sinus irritation or weaken the nostril’s pure filtration system, even in beforehand wholesome folks, mentioned Dr. Kevin Hur, an ear, nostril and throat specialist with Keck Drugs of USC.
“Your nose itself is considered a filter,” Hur mentioned. “As you breathe in smoke, it gets caught inside your sinuses, and if you’re exposed a lot, some of that will start to irritate the lining and lead to inflammation.”
The consequences could be delicate at first. Past apparent signs similar to a scratchy throat and runny nostril, Hur urges folks to observe for modifications of their sense of odor or whether or not their usually skinny, clear mucus turns into thicker.

When you develop thicker mucus or discover modifications in your sense of odor, Hur advises looking for medical analysis, as these may point out that pollution have compromised your nasal lining, probably resulting in an infection.
Eyes
The eyes are one other susceptible entry level for smoke and pollution.
“Particulate matter and gases from smoke can cause irritation, discomfort and even sometimes blurred vision, mostly due to disruption of the natural tear film on the eye,” mentioned Dr. Katherine S. Hu of the John A. Moran Eye Middle on the College of Utah.
For cover, Hu recommends sporting wraparound glasses or goggles when open air and avoiding touching or rubbing your eyes. If irritation happens, she advises utilizing synthetic tears like Refresh or Systane, which could be purchased over-the-counter and used a number of occasions a day. However beware: There’s a distinction between synthetic tears and different merchandise solely meant to scale back redness.
“Avoid products that only target red-eye relief like Visine,” she mentioned. “They only constrict your blood vessels to decrease the appearance of redness, but they won’t actually lubricate your eyes.”
For extra extreme discomfort, Hu suggests utilizing thicker lubricating gels or ointments at bedtime, although these might briefly blur imaginative and prescient.
One essential warning: “Don’t rinse your eyes with tap water, especially if you have contact lenses,” Hu mentioned. “It can change the chemical makeup of your natural tear film and cause even more irritation.”
Pores and skin
The threats to pores and skin well being are equally regarding and are exacerbated by Southern California’s dry winter season, says Dr. Teo Soleymani, who holds college positions at each UCLA Olive View-Medical Middle and at USC.
“As our skin dries out, there are microscopic cracks that occur in our skin, which allow environmental allergens and pollutants to enter that would otherwise not enter more hydrated skin,” he mentioned.
These cracks turn into notably harmful throughout wildfires, because the air fills with ash, aerosolized toxins from burning constructions and even plant compounds.
“Creams and ointments are always better than lotions, things out of jars are always better than things out of a pump bottle.”

“Every time the hillsides burn in Southern California, we see patients coming in with pretty severe contact allergen rashes,” Soleymani mentioned. “Patients who just live at the hillside will come in with poison oak or poison ivy flares covering the entirety of their body, even though they didn’t come into contact with these plants, and that’s because these toxins are aerosolized from the fires.”
Soleymani emphasizes moisturizing with thick merchandise.
“Creams and ointments are always better than lotions, things out of jars are always better than things out of a pump bottle,” he mentioned. “For hands and feet, which have really thick skin, you want to use something that’s ointment-based. Even simple things like Vaseline or Aquaphor will really make the difference.”
Whereas medical doctors proceed to be taught extra about wildfire smoke’s affect on well being, latest research have proven that long-term results on pores and skin circumstances are additionally a priority. Dr. Shadi Kourosh, an affiliate professor at Harvard Medical Faculty and affiliate professor of environmental well being on the Harvard Faculty of Public Well being labored on a latest examine after the 2023 Canadian wildfires which have proven important will increase in eczema flares throughout wildfire occasions.
“These airborne pollutants are corrosive to the skin barrier, causing inflammation, triggering eczema and also can accelerate the aging process of the skin and increase the risk of skin cancer,” she mentioned.
Kourosh’s analysis has led to particular suggestions for pores and skin safety throughout fireplace occasions, similar to utilizing mineral sunscreen containing zinc and titanium dioxide.
“These create a barrier on top of the skin that can help protect it from these corrosive airborne pollutants,” she mentioned.
After any out of doors publicity, Kourosh advises instantly altering garments, showering and making use of moisturizer to revive the pores and skin barrier. However that may be exhausting for individuals who simply misplaced all the pieces, the poor or unhoused. Which is why Kourosh emphasizes these fires should be handled as a broader public well being disaster requiring authorities intervention.
“These increasing wildfires due to climate-related factors are causing acute air-pollution events that are not only a threat to public safety, they’re a threat to human health,” she mentioned.
