Wildfire Smoke: What Are The Health Risks?

Wildfire smoke is a mix of gases and fine particles from burning trees, plants, buildings, and other materials. Breathing in smoke can have an immediate effect on your health, causing a range of ailments from relatively minor symptoms such as stinging eyes, a scratchy throat, and a runny nose, to more serious health effects such as exacerbation of asthma and heart failure, and even premature death.

Headaches, fatigue and a fast heartbeat

Breathing in wildfire smoke can cause a range of health issues, including headaches, fatigue and a fast heartbeat. These symptoms are caused by the mix of gases and fine particles from burning trees and plants, buildings, and other materials. Even healthy people can experience transient reductions in lung function and pulmonary inflammation from exposure to fine particles. Particle pollution may also affect the body's ability to remove inhaled foreign materials, such as viruses and bacteria, from the lungs.

Wildfire smoke can make anyone sick, but some people are at a higher risk of getting ill. Those with chronic conditions like asthma, Chronic Obstructive Pulmonary Disease (COPD), diabetes, chronic kidney disease, or heart disease are particularly vulnerable. Children are also more likely to be affected by air pollutants because their airways are small and still developing, and they breathe in more air relative to their body weight than adults.

If you are experiencing minor symptoms such as headaches, fatigue, and a fast heartbeat, there is no need to seek medical care. However, if you have asthma and the outdoor air quality causes an exacerbation that you cannot manage at home, you should contact your doctor. Chest pain or trouble breathing also warrants a call to your medical provider.

To protect yourself from the harmful effects of wildfire smoke, it is important to stay informed about air quality levels in your area and take appropriate precautions, such as wearing a mask or staying indoors when smoke levels are high.

Transient reductions in lung function

Exposure to wildfire smoke can cause a range of health issues, even in healthy people. One of the most common issues is transient reductions in lung function. This is caused by the fine particles and gases present in the smoke, which come from burning trees, plants, buildings, and other materials. These fine particles can be inhaled deep into the lungs, causing irritation and inflammation.

The effects of breathing in wildfire smoke can be immediate, with symptoms such as stinging eyes, a scratchy throat, a runny nose, coughing, sinus irritation, wheezing, and shortness of breath. These symptoms are similar to those experienced by people with allergies. However, the impact of wildfire smoke on lung function can be more serious, particularly for those with pre-existing respiratory conditions.

People with chronic conditions such as asthma, Chronic Obstructive Pulmonary Disease (COPD), bronchitis, and heart disease are at a higher risk of experiencing exacerbations of their conditions due to wildfire smoke exposure. For example, high levels of ground-level ozone, which is a common component of wildfire smoke, can aggravate lung diseases and trigger asthma attacks.

Additionally, the fine particles in wildfire smoke can affect the body's ability to remove foreign materials, such as viruses and bacteria, from the lungs. This can increase the risk of respiratory infections and other lung-related complications. It is important to note that children are also more susceptible to the health effects of wildfire smoke due to their smaller, developing airways and higher respiratory rates relative to their body weight.

To protect yourself from the harmful effects of wildfire smoke, it is recommended to stay indoors as much as possible, especially if you are in an area with poor air quality. If you need to go outside, wearing a well-fitting mask can help reduce your exposure to fine particles and gases. Additionally, keeping indoor air clean by using air purifiers or filters can help minimise the impact of wildfire smoke on your lung function.

Pulmonary inflammation

Exposure to wildfire smoke can lead to pulmonary inflammation. Even healthy people can experience transient reductions in lung function and pulmonary inflammation from breathing in fine particles. Particle pollution can also affect the body's ability to remove inhaled foreign materials, such as viruses and bacteria, from the lungs.

Wildfire smoke is a mix of gases and fine particles from burning trees and plants, buildings, and other materials. It can make anyone sick, but some people are at higher risk, including those with chronic conditions like asthma, Chronic Obstructive Pulmonary Disease (COPD), diabetes, chronic kidney disease, or heart disease.

The health effects of particle pollution exposure can range from relatively minor symptoms, such as eye and respiratory tract irritation, to more serious health effects, such as exacerbation of asthma and heart failure, and even premature death. Fine particles are respiratory irritants, and exposure to high concentrations can cause persistent coughing, phlegm, wheezing, and difficulty breathing.

Ozone levels are generally highest on hot, sunny days, often in the summer in the late afternoon and evenings. High ozone levels can also aggravate lung diseases, such as asthma, bronchitis, and COPD. For many people, the symptoms of inhaling particulate matter are similar to what someone with allergies experiences, including stinging eyes, a scratchy throat, a runny nose, coughing, sinus irritation, wheezing, and shortness of breath.

Eye and respiratory tract irritation

Wildfire smoke is a mix of gases and fine particles from burning trees and plants, buildings, and other materials. Even healthy people can experience transient reductions in lung function and pulmonary inflammation from exposure to fine particles. Particle pollution may also affect the body's ability to remove inhaled foreign materials, such as viruses and bacteria, from the lungs.

The health effects of particle pollution exposure can range from relatively minor to more serious. Minor health effects include eye and respiratory tract irritation, such as stinging eyes, a scratchy throat, a runny nose, coughing, sinus irritation, and shortness of breath. Exposures to high concentrations of fine particles can cause persistent coughing, phlegm, wheezing, and difficulty breathing.

People with chronic conditions like asthma, Chronic Obstructive Pulmonary Disease (COPD), diabetes, chronic kidney disease, or heart disease are at higher risk of experiencing more serious health effects from wildfire smoke. For example, particle pollution can exacerbate asthma and heart failure and even lead to premature death.

Breathing in smoke can also cause headaches, fatigue, and a fast heartbeat. Children are more likely to be affected by air pollutants because their airways are small and still developing, and they breathe in more air relative to their body weight than adults.

Exacerbation of asthma and heart failure

Wildfire smoke is a mix of gases and fine particles from burning trees, plants, buildings, and other materials. Even healthy people can experience transient reductions in lung function and pulmonary inflammation from exposure to fine particles. Particle pollution may also affect the body's ability to remove inhaled foreign materials, such as viruses and bacteria, from the lungs.

People with chronic conditions like asthma, COPD, diabetes, chronic kidney disease, or heart disease are at a higher risk of getting sick from wildfire smoke. For people with asthma, inhaling wildfire smoke can cause an exacerbation of symptoms that can't be managed at home, such as with a rescue inhaler. This may include persistent coughing, phlegm, wheezing, and difficulty breathing. If you are experiencing these symptoms, you should contact your doctor.

Children are also more likely to be affected by air pollutants because their airways are small and still developing, and they breathe in more air relative to their body weight than adults.

Additionally, wildfire smoke can aggravate lung diseases such as bronchitis and lead to more serious health effects, including exacerbation of heart failure and premature death.
