If you have ever stepped outside during wildfire season and felt the sting in your eyes and the tightness in your chest, you already know that wildfire smoke is more than an inconvenience. For many of us, hazy orange skies have become a recurring reality, and the health effects of that smoke reach far beyond your eyes and lungs. Having watched how quietly toxins can undermine health in my own patients, I do not take this lightly.

Here is the good news: you cannot always control the air outside, yet you have real power to protect yourself and support your body's ability to recover. I want to walk you through what wildfire smoke actually does to your body, the symptoms to watch for, and the concrete steps I take myself, including the AIRDoctor® air filters I run in my own home.

What Is in Wildfire Smoke?

Smoke is not a single substance. It is a mixture of particulate matter, often called soot, and chemicals released by the incomplete burning of carbon-containing materials. The two biggest concerns for your health are carbon monoxide and fine particulate matter, known as PM2.5, particles 2.5 microns or smaller that are small enough to travel deep into your lungs and even enter your bloodstream.

When wildfires burn homes, vehicles, and other manufactured materials, as they almost always do, the smoke also carries toxic compounds such as benzene, formaldehyde, polycyclic aromatic hydrocarbons, heavy metals, and dioxins. If you want to understand your overall toxic burden, learning how to test for toxins is a helpful place to begin.

The Health Effects of Wildfire Smoke

Wildfire smoke affects your body on several levels at once. Carbon monoxide reduces the oxygen supply to your tissues, which can cause headaches, reduced alertness, and, at high concentrations, far more serious harm. Fine particulate matter irritates your airways, triggers shortness of breath, and can worsen asthma along with existing heart and lung conditions. For a deeper look at the role oxygen plays in healing and recovery, listen to my conversation with Dr. Scott Sherr about the healing power of hyperbaric oxygen therapy on the “Take Back Your Health” podcast. 

The effects run deeper than the respiratory system. A Stanford study found that children exposed to high levels of particulate matter showed changes in a gene involved in the development and function of their T cells, a key part of the immune system. (1) Researchers also believe that smoke, by provoking oxidative stress, may contribute to autoimmunity by dysregulating DNA methylation, and that it can alter the lung environment in ways that make infections more likely. (2) I saw firsthand in my clinic how heavily a toxic burden can weigh on the immune system. On top of all this, the stress of living through a frightening, disruptive event takes its own toll on both body and mind.

Symptoms of Smoke Inhalation

Smoke inhalation shows up in ways that are easy to dismiss until they pile up. The most common symptoms include:

• Coughing, wheezing, and shortness of breath

• Chest tightness or discomfort

• Headaches and reduced alertness

• Red, itchy, or watering eyes

• Sinus congestion and a sore throat

• Fatigue and difficulty concentrating

People with asthma, heart conditions, or lung conditions, along with children and older adults, tend to feel these symptoms most acutely. Depending on the level of exposure, they can linger for days or even weeks after the air begins to clear.

How to Protect Yourself From Wildfire Smoke

Reducing your exposure is always the first priority. These are the steps I recommend:

• If emergency officials issue an evacuation order, follow it immediately. Every moment matters.

• Stay indoors with your windows closed when air quality is poor.

• Filter your indoor air with a high-efficiency (HEPA) air filter, which can dramatically reduce indoor particulate concentrations. I use AIRDoctor® air filters throughout my home.

• Wear a properly fitted mask when you need to go outside.

• Avoid adding to indoor particulates by not lighting candles, smoking, or vacuuming during a smoke event.

• Stay well hydrated with filtered water, and avoid heavy exertion outdoors.

How to Support Your Body's Natural Detox

Once smoke has entered your body, supporting your natural detoxification pathways helps you clear the accumulated burden, which matters most with longer-term exposure. This is exactly what Pillar III of The Myers Way®, Tame the Toxins, is all about. All of my supplements are physician-formulated and free of gluten, wheat, dairy, corn, soy, GMOs, and yeast.

Three targeted formulas work together to support this process. Acetyl-Glutathione replenishes your master antioxidant, which is rapidly depleted when your body is under a heavy toxic load. Liver Support gives your liver what it needs to process and clear toxins through its natural detoxification pathways, including NAC, a precursor to glutathione that helps support your body’s antioxidant defenses. Charcoal Binder Complete binds toxins in your gut and helps escort them out before they can be reabsorbed. You can find all three together in the Detox & Die-off Support Bundle, designed to help your body navigate the detoxification process and support your natural detox pathways.

A few daily habits round out your recovery. Sweating in a Sunlighten infrared sauna is one of the most efficient ways to move toxins out through your skin, your largest organ. Eating well matters too, so lean on foods that support natural detoxification and explore the full detox support collection for additional tools. If smoke has left you with a raw, scratchy throat, the marshmallow root and slippery elm in Leaky Gut Revive® can help soothe and support your mucous membranes.

Wildfires and Our Planet

It is worth remembering that a warming, drier climate is fueling more frequent and intense wildfires, and that no large fire is truly isolated to one region. The encouraging truth is that small, collective actions add up. Planting trees, reducing waste, and being mindful of our daily footprint all contribute to healthier air for everyone.

Breathe Easier and Support Your Body

You cannot control every breath of air around you, but you can control how well you protect and support your body. Using high-quality AIRDoctor® air filters can help reduce airborne contaminants in your home, while the Detox & Die-off Support Bundle provides targeted support for your body’s natural detoxification pathways. Filter your air, reduce your exposure, nourish your body, and lean on The Myers Way® to stay resilient season after season. Your body is remarkably capable of recovering when you give it the support it needs.

FAQs

• What are the symptoms of smoke inhalation?
  The most common symptoms of smoke inhalation include coughing, wheezing, shortness of breath, and chest tightness, along with headaches, red or watering eyes, sinus congestion, and a sore throat. Many people also notice fatigue and difficulty concentrating. These symptoms occur because the fine particulate matter and carbon monoxide in smoke irritate your airways and reduce your body's oxygen supply. People with asthma, heart or lung conditions, children, and older adults tend to experience more pronounced symptoms, and depending on the level of exposure, they can persist for days or even weeks.
• Can wildfire smoke cause headaches?
  Yes. Headaches are one of the most common and earliest symptoms of wildfire smoke exposure. They are largely driven by the carbon monoxide in smoke, which reduces the amount of oxygen reaching your brain and tissues. The stress and poor sleep that often accompany living through a wildfire can add tension headaches on top of that. If you are experiencing frequent headaches during a smoke event, it is a clear signal to reduce your exposure, filter your indoor air, and support your body's natural detoxification.
• Is wildfire smoke bad for you?
  Yes, wildfire smoke can be harmful, especially with repeated or prolonged exposure. It contains fine particulate matter (PM2.5) small enough to travel deep into your lungs and enter your bloodstream, along with carbon monoxide and toxic compounds such as benzene and formaldehyde when homes and vehicles burn. Beyond the immediate respiratory effects, emerging research links smoke exposure to immune disruption and oxidative stress that may contribute to autoimmunity. The good news is that reducing exposure and supporting your body's detox pathways can meaningfully lower the burden.
• How do you detox your body after wildfire smoke exposure?
  Start by reducing further exposure, since detox cannot keep up with an ongoing intake of smoke. From there, support your body's natural detoxification pathways. Acetyl-Glutathione replenishes the master antioxidant depleted by a high toxic burden, Liver Support helps your liver process toxins, and Charcoal Binder Complete binds toxins so they leave your body rather than being reabsorbed. Sweating through an infrared sauna, staying hydrated with filtered water, and eating nutrient-dense foods that support detoxification all give your body additional support.
• How long do the health effects of wildfire smoke last?
  It depends on the intensity and duration of your exposure and your overall health. Mild symptoms such as eye irritation and coughing often ease within days once the air clears and you reduce exposure. Heavier or prolonged exposure can cause effects that linger for weeks, and research suggests the immune impact of significant particulate exposure may persist longer still. This is why supporting your body's natural detoxification and filtering your indoor air matter, especially if you live in a wildfire-prone area where exposure recurs season after season.
