Wildfire smoke inside homes can create health risks that linger for months − tips for cleaning and staying safe
Wind-driven wildfires in Los Angeles released toxic chemicals from burned materials into homes, causing health symptoms like headaches and respiratory issues. Proper cleaning and protective measures are essential post-wildfire.

When wildfires spread into neighborhoods, they burn all kinds of materials found in cars and houses and everything around them – electronics, paint, plastics, furniture.
Research shows that the mix of chemicals released when human-made materials like these burn is different from what is emitted during a vegetation fire and is potentially more toxic. The smoke and ash can blow under doors and around windows in nearby homes, bringing in chemicals that are absorbed into furniture, walls and other indoor surfaces and continue off-gassing for weeks to months.
As people return to smoke-damaged homes after a wildfire, there are several steps they can take to protect their health before starting to clean.
Elevated levels of metals and VOCs
In 2021, after the Marshall Fire swept through neighborhoods near Boulder, Colorado, my colleagues and I at Colorado universities and labs heard from many residents who were worried about the ash and lingering smells inside their homes that had otherwise survived the flames.
In homes that my colleagues were able to quickly test, they found elevated levels of metals and PAHs – polycyclic aromatic hydrocarbons – in the ash. We also found elevated VOCs – volatile organic compounds – in airborne samples. Some VOCs, such as dioxins, benzene, formaldehyde and PAHs, can be toxic to humans. Benzene is a known carcinogen.
At the time, we could find no information about physical health implications for people who have returned to smoke-damaged homes after a wildfire. So, to look for patterns, we surveyed residents affected by the fire six months, one year and two years after the fire.
Even six months after the fire, we found that many people were reporting symptoms that aligned with health risks related to smoke and ash from fires.
More than half (55%) reported that they were experiencing at least one symptom six months after the blaze that they attributed to the Marshall Fire. The most common symptoms reported were itchy or watery eyes (33%), headache (30%), dry cough (27%), sneezing (26%) and sore throat (23%).

All of these symptoms, as well as having a strange taste in one’s mouth, were associated with people reporting that their home smelled differently when they returned to it one week after the fire.
Many survey respondents said that the smells decreased over time. Most attributed the improvement in smell to the passage of time, cleaning surfaces and air ducts, replacing furnace filters, and removing carpet, textiles and furniture from the home. Despite this, many still had symptoms.
We also found that living near a large number of burned structures was associated with these health symptoms. We found that for every 10 additional destroyed buildings within 820 feet (250 meters) of a person’s home, there was an associated 21% increase in headaches and a 26% increase in having a strange taste in their mouth.
These symptoms align with what could be expected from exposure to the chemicals that we found in the ash and measured in the air inside the few smoke-damaged homes that we were able to study in depth.
Lingering symptoms and questions
There are a still a lot of unanswered questions about the health risks from smoke- and ash-damaged homes.
For example, we don’t yet know what long-term health implications might look like for people living with lingering gases from wildfire smoke and ash in a home. We found a significant decline in the number of people reporting symptoms one year after the fire. However, 33% percent of the people whose homes were affected and responded to a later survey still reported at least one symptom that they attributed to the fire. About the same percentage also reported at least one symptom two years after the fire.
We also could not measure the level of VOCs or metals that each person was exposed to. But we do think that reports of a change in the smell of a person’s home one week after the fire demonstrates the likely presence of VOCs in the home. That likely has health implications for people whose homes are exposed to smoke or ash from a wildfire.
Tips to protect yourself after wildfires
Wildfires are increasingly burning homes and other structures as more people move into the wildland-urban interface, temperatures rise and fire seasons lengthen.
If your home survives a wildfire nearby, here are some of the steps to think about before starting to clean:
- When you’re ready to clean your home, start by protecting yourself. Wear at least an N95 (or KN95) mask and gloves, goggles and clothing that covers your skin. Cleaning can send some of those gases and ash into the air again.
- Keep people with heart or lung diseases, older adults, pregnant women, children and pets away from cleanup activities.
- Vacuum floors, drapes and furniture. A recent scientific study documents how cleaning all surfaces within a home can reduce reservoirs of VOCs and lower indoor air concentrations of VOCs. Once the air outside has cleared, open windows to let clean air in.
- Avoid harsh chemical cleaners because they can react with the chemicals in the ash.
- Clean your HVAC filter and ducts to avoid spreading ash further, and change filters monthly until the smell is gone. Portable air cleaners with carbon filters can help remove VOCs and particles.
- If your car smells of smoke, consider changing the cabin air filter.

How to avoid seeing disturbing video on social media and protect your peace of mind
How to avoid seeing disturbing video on social media and protect your peace of mind

How to avoid seeing disturbing video on social media and protect your peace of mind
When graphic videos like those of the recent shooting of a protester by federal agents in Minneapolis go viral, it can feel impossible to protect yourself from seeing things you did not consent to see. But there are steps you can take.
Social media platforms are designed to maximize engagement, not protect your peace of mind. The major platforms have also reduced their content moderation efforts over the past year or so. That means upsetting content can reach you even when you never chose to watch it.
You do not have to watch every piece of content that crosses your screen, however. Protecting your own mental state is not avoidance or denial. As a researcher who studies ways to counteract the negative effects of social media on mental health and well-being, I believe it’s a way of safeguarding the bandwidth you need to stay engaged, compassionate and effective.
Why this matters
Research shows that repeated exposure to violent or disturbing media can increase stress, heighten anxiety and contribute to feelings of helplessness. These effects are not just short-term. Over time, they erode the emotional resources you rely on to care for yourself and others.
Protecting your attention is a form of care. Liberating your attention from harmful content is not withdrawal. It is reclaiming your most powerful creative force: your consciousness.
Just as with food, not everything on the table is meant to be eaten. You wouldn’t eat something spoiled or toxic simply because it was served to you. In the same way, not every piece of media laid out in your feed deserves your attention. Choosing what to consume is a matter of health.
And while you can choose what you keep in your own kitchen cabinets, you often have less control over what shows up in your feeds. That is why it helps to take intentional steps to filter, block and set boundaries.
Practical steps you can take
Fortunately, there are straightforward ways to reduce your chances of being confronted with violent or disturbing videos. Here are four that I recommend:
- Turn off autoplay or limit sensitive content. Note that these settings can vary depending on device, operating system and app version, and can change.
https://datawrapper.dwcdn.net/d1deR/2
- Use keyword filters. Most platforms allow you to mute or block specific words, phrases or hashtags. This reduces the chance that graphic or violent content slips into your feed.
- Curate your feed. Unfollow accounts that regularly share disturbing images. Follow accounts that bring you knowledge, connection or joy instead.
- Set boundaries. Reserve phone-free time during meals or before bed. Research shows that intentional breaks reduce stress and improve well-being.
Reclaim your agency
Social media is not neutral. Its algorithms are engineered to hold your attention, even when that means amplifying harmful or sensational material. Watching passively only serves the interests of the social media companies. Choosing to protect your attention is a way to reclaim your agency.
The urge to follow along in real time can be strong, especially during crises. But choosing not to watch every disturbing image is not neglect; it is self-preservation. Looking away protects your ability to act with purpose. When your attention is hijacked, your energy goes into shock and outrage. When your attention is steady, you can choose where to invest it.
You are not powerless. Every boundary you set – whether it is turning off autoplay, filtering content or curating your feed – is a way of taking control over what enters your mind. These actions are the foundation for being able to connect with others, help people and work for meaningful change.

I’m the executive director of the Post-Internet Project, a nonprofit dedicated to helping people navigate the psychological and social challenges of life online. With my team, I designed the evidence-backed PRISM intervention to help people manage their social media use.
Our research-based program emphasizes agency, intention and values alignment as the keys to developing healthier patterns of media consumption. You can try the PRISM process for yourself with an online class I launched through Coursera in October 2025. You can find the course, Values Aligned Media Consumption, on Coursera. The course is aimed at anyone 18 and over, and the videos are free to watch.

Understanding Cardiovascular Disease Risk Factors: Numbers to Know in 2026
The American Heart Association’s 2026 update reveals a decrease in deaths from heart disease and stroke, despite rising rates of high blood pressure, diabetes, and obesity. Following their Life’s Essential 8 guidelines can prevent 40% of cardiovascular deaths, emphasizing the importance of healthier lifestyles for improved heart health.
Understanding Cardiovascular Disease Risk Factors: Numbers to Know in 2026
(Family Features) Taking care of your heart with healthy behaviors may be at the top of your wellness priority list already, and there may be good news about the effects of adhering to expert recommendations.
New information from the American Heart Association’s 2026 Heart Disease & Stroke Statistics Update shows deaths from heart disease and stroke are on the decline. However, rates continue to climb for high blood pressure, diabetes and obesity – all of which are health risk factors that contribute to cardiovascular disease.
Following expert guidance can be your prescription for better health as 80% of heart disease and stroke is preventable.
To help maintain and improve your cardiovascular health, consider following the American Heart Association’s Life’s Essential 8, which is a set of four health behaviors (eat better, be more active, quit tobacco and get healthy sleep) and four health factors (manage weight, control cholesterol, manage blood sugar and manage blood pressure).
In the United States, optimal Life’s Essential 8 scores could prevent up to 40% of annual all-cause and cardiovascular disease deaths among adults.
Consider these highlights from the statistics update:
- Heart disease remains the leading cause of death in the U.S. and stroke is the No. 4 leading cause of death.
- Together, heart disease and stroke accounted for more than a quarter of all deaths in the U.S. in 2023.
- Cardiovascular diseases, including all types of heart disease and stroke, claim more lives in the U.S. each year than all forms of cancer and accidental deaths — the Nos. 2 and 3 causes of death – combined.
- On average, every 34 seconds, someone died of cardiovascular disease in 2023.
- On average, about two people died of heart disease every 3 minutes in the U.S. in 2023.
- On average in 2023, someone died of stroke every 3 minutes, 14 seconds in the U.S.
- Nearly half of U.S. adults now have high blood pressure.
- Nearly 29.5 million U.S. adults have diagnosed diabetes.
- About 50% of U.S. adults have obesity or severe obesity, and 28.1% of youth ages 2-19 have obesity.
- Only 1 in 4 U.S. adults meets national physical activity guidelines. Only 1 in 5 U.S. youths ages 6-17 are physically active for 60 minutes or more every day of the week.

5 Tips to Upgrade Your Home Office
(Family Features) Hybrid schedules and remote work have become the norm for many people, which means a functional and inspiring workspace is more necessity than luxury. With the right setup – be it a dedicated room or a cozy corner – your space can boost productivity, spark creativity and make your workday more enjoyable. Consider these ideas to blend function, comfort and style, and create a home office that inspires creativity and makes you want to sit down and get things done. Focus on Comfort The desk and chair are the foundation of any home office. Be sure to build a setup that matches your work style by picking the right height desk (with the proper amount of storage and workspace to complete your tasks) and an adjustable chair with good lumbar support. If you’re at your computer most of the time during the day, an ergonomic keyboard and monitor stand can also make a comfortable difference. Create a Clutter-Free Work Zone Incorporating smart storage solutions like shelves, filing cabinets or baskets can help keep your workspace tidy and free of distracting clutter. Desk trays can keep small office supplies organized and within easy reach while maintaining a clean aesthetic. Add Personality with Decor Much like the rest of your home, your workspace should reflect your personality and style. Add artwork, decorative accents, plants or a photo wall to bring inspiration and freshness to your office and choose a color palette that promotes positivity and focus, such as soft blues, greens or neutrals. Layer Functional Lighting For optimal productivity, combine natural light with task and ambient lighting. If possible, position your desk near a window to capture natural light then supplement your space with a desk lamp for focused illumination and floor lamps, under-shelf lighting or wall sconces to add warmth and depth. Don’t Forget Acoustics Distracting noises can negatively impact focus. To absorb sound, use soft furnishings like rugs, upholstered chairs or curtains and consider a white noise machine if you need a more soothing work environment.
