Health and Wildfire Smoke

Wildfire smoke is made up of a complex mixture of gases and particles, including fine particulate matter (PM2.5). Unfortunately, these tiny particles easily move deep into the lungs and circulatory system. Once these particles reach the lungs and bloodstream, they can trigger inflammation and other unwanted health responses.
Researchers are learning more each year about the health implications of wildfire smoke. We'll continue to update this website with new reports. See our COVID page for more.

What are the health effects of wildfire smoke?

Smoke affects everyone differently, both physically and mentally. Healthy folks may or may not feel any immediate impacts during smoke events. Be cautious with how much time you spend and how active you are outdoors even if you do not experience any obvious symptoms of smoke related illness. Smoke exposure can potentially harm respiratory, cardiovascular, and immune system health.

For certain individuals, wildfire smoke could have very specific health implications. Read more below or speak to your health care provider.

Symptoms of smoke exposure
  • Coughing
  • Trouble breathing
  • Stinging or Itching eyes
  • Scratchy throat
  • Headache
  • Lack of energy
  • Changes to appetite
  • Changes in sleep patterns
  • Feelings of hopelessness, irritability, or depression​

For some individuals, smoke exposure can increase the risk of respiratory illness and infection such as bronchitis, asthma, pneumonia, and Chronic Obstructive Pulmonary Disease. Others may experience cardiovascular issues and even heart attack. Pay attention to your body and your loved ones, and talk to your doctor if you are concerned.

who is at risk?

Picture
While all of us are affected by smoke, some disproportionately experience health impacts. Children with developing lungs are at increased risk of health impacts because the particles can affect lung function and growth. Seniors, pregnant women, and people with asthma or other pre-existing conditions are at greater risk as well. If you or a loved one belongs in one of these groups, read more below to find out how they are at risk and what you can do to protect them.
​
Picture

​Children
Potential Effects from Smoke:
  • Risk of damage to lungs, which are still developing
  • Kids are more likely to be active when outdoors - running, playing, being kids - meaning they typically inhale more harmful chemicals per pound of body weight
What You Can Do:
  • Reduce the amount of time you’re breathing unhealthy air by going to or creating a Clean Indoor Air space. ​
Picture

Pregnant Women
Potential Effects from Smoke: 
  • Pre-existing respiratory or cardio conditions are worsened with smoke, making it harder to stay healthy while pregnant. 
  • Although the research is thin, there is concern about smoke particles moving from the Mom's bloodstream to the fetus or new baby.
What You Can Do: ​
  • Reduce the amount of time you’re breathing unhealthy air by going to or creating a Clean Indoor Air space. ​




Picture

Seniors (65+)
Potential Effects from Smoke: 
  • Increased susceptibility to bacterial or viral infections because of compromised immune system
​What You Can Do: 
  • Consult your healthcare provider and follow their advice if you have any specific medical concerns about prescription drugs that you are taking
  • Have an adequate supply of medication on hand (more than 5 days worth) in case of an emergency​
  • Reduce the amount of time you’re breathing unhealthy air by going to or creating a Clean Indoor Air space. ​
Picture

People who have asthma:
Potential Effects from Smoke:
  • More frequent and more severe asthma attacks
What You Can Do:
  • Create an asthma action plan with your healthcare provider at the beginning of the summer
  • Discuss prevention and treatment options for smoke events that are customized to you
  • Carry an emergency inhaler
  • Reduce the amount of time you’re breathing unhealthy air by going to or creating a Clean Indoor Air space. 
Picture

Chronic Heart or Lung Disease: 
Potential Effects from Smoke: 
  • Shortness of breath
  • COPD (chronic obstructive pulmonary disease)
  • Chest tightness
  • Pain in chest, neck, shoulder, or arm
  • Heart palpitations
  • Unusual fatigue or light headedness
What You Can Do: 
  • Consult your healthcare provider and follow their advice if you have any specific medical concerns about prescription drugs that you are taking
  • Have an adequate supply of medication on hand (more than 5 days worth) in case of an emergency​
  • Reduce the amount of time you’re breathing unhealthy air by going to or creating a Clean Indoor Air space. ​
Picture

Circulatory System Disease: 
Potential Effects from Smoke: 
  • Temporary chest pain
  • Heart attacks
  • Cardiac arrhythmia
  • Acute congestive heart failure
  • Stroke
What You Can Do: 
  • Consult your healthcare provider and follow their advice if you have any specific medical concerns about prescription drugs that you are taking
  • Have an adequate supply of medication on hand (more than 5 days) in case of an emergency
  • Reduce the amount of time you’re breathing unhealthy air by going to or creating a Clean Indoor Air space. ​

 

Stay healthy during smoke events

  • For reducing smoke exposure at home, consider purchasing a HEPA air filtration unit.
  • We highly recommend this OUTDOOR ACTIVITY recommendation chart to help decide when to be active. It's designed for coaches, schools, day care centers, and summer camps, but it's handy for anyone who works or plays in the outdoors.
  • When the air is unhealthy, indoors may be the best place to be. Learn how to create healthy indoor air at home. 
  • If you work outside and can't avoid the smoke, any amount of time spent in an indoor space where the air is cleaner can help - even if that's just on your lunch break or after you get home from work.
  • Another option for keeping particulate matter from wildfire smoke out of your lungs is to wear a particulate respirator mask, also known as an N95 or P100 mask, with two straps. One-strap masks, surgical masks, and bandanas do NOT filter out the tiny particulate matter present in wildfire smoke. Keep in mind that particulate respirator masks must fit tightly to work properly, so they actually make breathing more difficult and are not recommended for folks who already have trouble breathing, or for use while engaged in strenuous physical activity.​
Physical activity during wildfire smoke
When we exercise, we breathe more quickly and deeply. During periods of wildfire smoke, this means that we pull more pollutants into our lungs than we would while breathing normally at a resting heart rate. Because of this increased rate of inhaling smoke pollution, people who exercise frequently outdoors may be at greater risk of experiencing harmful health impacts during times of smoke, especially if they choose to continue outdoor activity. 

If possible, reduce outdoor physical activity, and ensure any indoor activity is in a space with filtered air. See our Public Spaces page to know what questions to ask your local gym in order to know how safe the indoor air is. Getting outside is important though, and no one wants to miss the warm sunny days of summer, so be sure to check current air quality and smoke forecasts on our TodaysAir page so that you can plan your outdoor activity for times with less smoke.

Mental and physical health is important, so be sure to find a balance between protecting yourself from smoke and getting outside to move around. And remember, the smoke will clear!

Competitors and Coaches
Losing precious time to train, practice, and workout is a pain. When wildfire smoke lingers for multiple weeks, it's easy to brush it off and decide to push through it, thinking that staying indoors could be more detrimental to a season. However, the growing body of research on wildfire smoke is showing that even in healthy individuals, harmful health impacts can be seen long after the smoke dissipates. Asthma, lung infections such as bronchitis and pneumonia, and more are linked to wildfire smoke exposure, and could be just as disruptive to a season, if not more. It's also important to recognize that all people will react to smoke differently, and athlete complaints of discomfort should be taken seriously.

Below are recommendations for school outdoor activity provided by the Montana Department of Environmental Quality. They also work well as general guidelines for anyone who frequently exercises outdoors.

Read the 'Outdoor Physical Activity' section on our Outdoor Safety page for more.

Although these recommendations are specific to schools and childcare facilities, they are also a good set of guidelines to follow for anyone who regularly exercises outdoors.
