Bushfires And Asthma: Impact of Prolonged Bushfire Smoke Exposure


Table of Contents

Bushfire and Asthma: As the devastating impact of bushfires continues to affect communities around the world, it is crucial to shed light on the connection between bushfire smoke and asthma. For individuals living with asthma, the presence of smoke can pose significant health risks and exacerbate their condition.

In this blog, we will address the groups most vulnerable to the adverse effects of bushfire smoke on asthma, and provide practical tips on minimising exposure and managing symptoms during bushfire season. By understanding the risks and taking appropriate precautions, individuals with asthma can navigate this condition with greater confidence and well-being.

What Is Bushfire Smoke And How Does It Affect Asthma?

Bushfire smoke refers to the particulate matter and gases released into the air during wildfires or bushfires. These fires generate a complex mixture of pollutants, including fine particles, gases, and volatile organic compounds, which can have significant health implications, particularly for individuals with asthma.

When inhaled, the fine particles in bushfire smoke can penetrate deep into the respiratory system, reaching the lungs and triggering a range of respiratory issues. For people with asthma, these particles can act as irritants and exacerbate their condition, leading to range of symptoms.

The particles in bushfire smoke can cause inflammation in the airways, constricting them and making it harder for air to flow freely. This can result in increased bronchial sensitivity and heightened asthma symptoms. Furthermore, the presence of gases and volatile organic compounds in bushfire smoke can further irritate the airways and worsen respiratory distress.

It is important to note that individuals with pre-existing asthma are more susceptible to the adverse effects of bushfire smoke.

Recognising The Symptoms

Recognising the symptoms of asthma exacerbated by bushfire smoke is crucial for timely intervention and management. While symptoms can vary from person to person, there are common indicators to watch out for. Here are some key symptoms to be aware of:

  • Persistent or frequent coughing
  • Wheezing
  • Shortness of breath
  • Chest tightness or discomfort
  • Increased respiratory rate
  • Reduced exercise tolerance
  • Fatigue

It’s important to remember that asthma symptoms can vary in intensity and duration for different individuals. Some people may experience mild symptoms, while others may have more severe or prolonged episodes. Additionally, individuals who do not typically have asthma may also experience temporary respiratory discomfort or irritation due to the presence of bushfire smoke.

Risk Factors For Bushfire Smoke-Related Asthma Attacks

Asthma attacks related to bushfire smoke exposure can affect anyone, but some people are more susceptible than others. People with pre-existing asthma, children, elderly individuals, those with compromised respiratory systems, and outdoor workers are at higher risk of experiencing severe asthma attacks when exposed to bushfire smoke. 

By understanding who is at most risk, we can take appropriate precautions to safeguard our respiratory health during bushfire seasons.

First Aid For Asthma

First aid for asthma involves providing immediate assistance to someone experiencing an asthma attack triggered by the smoke. While it is important to remember that first aid does not substitute proper medical care, here are some steps you can take to help someone during an asthma attack caused by bushfire smoke:

Stay Calm

It is crucial to remain calm and reassure the person experiencing the asthma attack. Anxiety or panic can worsen their symptoms.

Assist With Medication

If the person has their prescribed asthma medication, help them use it as directed. This typically involves using an inhaler or a nebulizer. If they are unsure how to use it or do not have their medication available, call for medical assistance immediately.

Help Them Find A Comfortable Position

Encourage the person to sit upright and lean slightly forward. This position can help ease breathing and reduce strain on the airways.

Eliminate Exposure To Smoke

If possible, move the person to an area with cleaner air, away from the source of the bushfire smoke. This could mean moving indoors or to a vehicle with windows closed and air conditioning on recirculation mode.

Loosen Tight Clothing

If the person’s clothing is tight or constricting, help them loosen it to allow for easier breathing.

Monitor Their Condition

Remain with the person until medical help arrives. Keep a close eye on their breathing and overall condition. If their symptoms worsen, if they have trouble speaking or their lips turn blue, call emergency services immediately.

Offer Comfort And Support

Providing emotional support can help the person remain calm and manage their distress. Reassure them that help is on the way and that they are not alone.

Remember, each person’s asthma management plan may differ, so it is essential to respect their individual needs and preferences. 

Encourage the person to seek medical attention and follow up with their healthcare provider to ensure proper evaluation and ongoing management of their asthma.

How To Prepare For Bushfire Season

Preparing for bushfire season is particularly important for individuals living with asthma, as bushfire smoke can exacerbate their respiratory symptoms. Here are some steps you can take to prepare and manage your asthma during bushfire season:

Stay Informed

Stay updated on local bushfire conditions and air quality reports. Monitor reliable sources of information such as your local fire department, meteorological agencies, or government websites for updates on bushfire activity in your area.

Develop An Asthma Action Plan

Work with your healthcare provider to create a personalized asthma action plan. This plan should outline specific steps to take during asthma flare-ups, including the use of medications, when to seek medical assistance, and emergency contact information.

Ensure Adequate Medication Supply

Make sure you have an ample supply of your prescribed asthma medications, including inhalers, spacers, or nebulizers. Check expiration dates and refill prescriptions in advance to avoid running out during bushfire season.

Stay Indoors 

If the air quality is significantly affected by bushfire smoke, it is best to remain indoors as much as possible. Close windows and doors, and limit physical activity to reduce exposure to smoke.

Learn First Aid

Learning first aid for bushfire-related asthma equips you with the knowledge and skills to be prepared for emergencies. You’ll be able to assess situations effectively, take appropriate measures, and potentially save lives.

First aid courses cover important safety measures, including proper use of personal protective equipment (PPE) and precautions to take in hazardous environments. Understanding these aspects ensures your own safety while providing assistance during bushfire events.

By taking a first aid course with a reputable organisation such as the First Aid Courses Perth, you will learn how to recognize and respond to symptoms of asthma, administer first aid techniques, and provide support until medical professionals arrive. 

Ultimately, being equipped with these critical skills can help save lives and make a difference in your community.
