Wildfires: How to cope when smoke affects air quality and health

Learn how to cope with wildfires and their impact on air quality and health, from protective measures to managing symptoms.

Sandhya 4 min read
When wildfires rage, the resulting smoke doesn’t just darken our skies—it invades our lungs, homes, and minds. Exposure to fine particulate matter (PM₂.₅) in wildfire smoke is linked to respiratory irritation, exacerbation of asthma, cardiovascular stress, and even long-term health issues like dementia and reduced birth outcomes. This blog explores practical steps to safeguard your physical and mental wellbeing during smoky days, backed by expert guidance from the CDC, Harvard, and EPA.   
  1. Understand the Threat
Wildfire smoke contains fine and ultrafine particles (PM₂.₅ and PM₀.₁) and harmful gases like carbon monoxide and volatile organic compounds. These penetrate deep into the lungs and bloodstream, triggering inflammation, heart strain, and weakened immune defenses . Even healthy individuals may experience coughing, eye irritation, headaches, and fatigue . Long-term exposure elevates risks of asthma, heart disease, adverse birth outcomes, and cognitive decline. 
  1. Stay Informed: Monitor the Air
Track local air quality via the Air Quality Index (AQI) on resources like AirNow or PurpleAir . AQI values: 0–50 (good) to 300+ (hazardous). Red, purple, and maroon alerts call for immediate action—stay inside and limit exposure .   
  1. Seal and Purify Indoors
  • Keep windows and doors shut, and block leaks with weather stripping or towels . 
  • Designate a clean room: a space with minimal outdoor openings, equipped with a HEPA filter or high-efficiency air purifier. 
  • Run your HVAC system with MERV 13+ filters on recirculation mode to avoid outdoor air intake. 
  • Avoid indoor pollution: skip vacuuming, frying food, burning candles, or smoking—these actions worsen air quality . 
 
  1. Use Protective Gear Outdoors
When outdoor exposure is unavoidable: 
  • Wear a well-fitting N95 or P100 respirator. Cloth or surgical masks don't offer sufficient protection from PM. 
  • Use respirators for young children with caution—NIOSH-approved sizes may not fit perfectly; ensure proper fit. 
  • Limit or avoid outdoor exercise, substituting for indoor workouts in filtered environments. 
  • In vehicles, keep windows up and use air conditioning on recirculation to avoid pulling in smoke. 
 
  1. Prepare Supplies & Evacuation Plans
  • Fund a "go bag": include masks, medications, water, important documents in case of evacuation . 
  • Set emergency alerts from local agencies, NOAA, or fire maps to stay informed . 
  • Protect children and pets: extra care for sensitive groups; keep them indoors, monitor symptoms, and design safe play spaces . 
 
  1. Support Your Mental Health
Wildfire smoke can disrupt routines, trigger stress or anxiety, and recall past traumas . To manage mental wellbeing: 
  1. Practice grounding techniques (5‑4‑3‑2‑1 method, deep breathing). 
  1. Stay socially connected, share feelings, reach out for support. 
  1. Maintain routines—indoor physical activity, structure, engaging hobbies. 
  1. Limit media exposure on fires to prevent overwhelm, especially for children. 
  1. Seek professional help if sleep, mood, or anxiety become persistent concerns . 
 
  1. Stay Engaged Community-Wise
Community-level strategies bolster individual resilience: 
  • Smoke‑ready initiatives include shared clean‑air centers and public mask distribution. 
  • Advances in air‑sensor networks help track pollution exposure and inform cleaner‑air guidelines . 
  • Pressure local governments to amplify emergency alert systems, offer support for vulnerable residents, and maintain accessible public shelters. 
 
  1. Long‑Term Resilience
Wildfire seasons are intensifying due to climate change. To strengthen preparedness: 
  • Invest in HVAC upgrades and HEPA filtration—studies show HEPA can halve household indoor pollution compared to untreated air . 
  • Adopt SMART forest management to reduce future smoke events and preserve air quality . 
  • Support equitable resource distribution, ensuring rural and low-income communities receive masks, filters, and clean-air access. 

 

Quick Reference Table 

Condition / AQI Alert  Recommended Action 
AQI > 150 (Unhealthy)  Stay indoors, use clean air room & HEPA purifier 
AQI > 200 (Very Unhealthy)  No outdoor exercise; mask first thing outdoors 
AQI > 300 (Hazardous)  Avoid all outdoor exposure; activate evacuation plan 
 

Final Thoughts 

Wildfire smoke poses serious threats that touch on our physical health, mental wellbeing, and community cohesion. By arming ourselves with knowledge—of AQI levels, indoor air strategies, respirators, emotional coping techniques, and preparedness plans—we can build resilience that carries us through smoky skies. Individually and collectively, these steps help us transform vulnerability into strength, turning an environmental emergency into a catalyst for healthier living and stronger bonds.
