How Your Home Decor Could Be Affecting Your Lungs – Page 23

1. Wall Paints and VOC Emissions

Many wall paints release volatile organic compounds (VOCs), which are chemicals that easily evaporate into the air and can be inhaled. These compounds are found in standard paints and can linger indoors for weeks after application. Exposure to VOCs is linked to symptoms like headaches, irritation of the eyes, nose, and throat, and, more seriously, to worsening respiratory conditions such as asthma or bronchitis. According to the U.S. Environmental Protection Agency (EPA), indoor concentrations of VOCs are often up to ten times higher than outdoors.

Low-VOC or zero-VOC paints have become increasingly popular as safer alternatives. These products emit significantly fewer harmful chemicals, reducing potential respiratory risks. When choosing paint, look for certifications like Green Seal or GREENGUARD, which indicate lower emissions.
Opting for low-VOC or natural, plant-based paints can help protect your lungs, especially if you have children, elderly family members, or anyone with pre-existing respiratory conditions in the home. Creating a healthier indoor environment starts with the walls that surround you every day.

2. Carpets and Dust Mites

While carpets may add warmth and style to a room, they are notorious for harboring dust mites—tiny creatures that thrive in warm, humid environments and feed on dead skin cells. These microscopic pests are among the most common indoor allergens, triggering sneezing, coughing, and asthma attacks, especially in sensitive individuals. According to the Asthma and Allergy Foundation of America, dust mites are a leading cause of year-round allergy symptoms and can exacerbate respiratory conditions.

Hard flooring options like wood, tile, or laminate are generally less hospitable to dust mites and easier to keep clean. Studies have shown that rooms with hard floors contain fewer allergens compared to carpeted spaces. If you prefer the comfort of carpets, regular cleaning is essential.
Use a vacuum with a HEPA filter, wash area rugs and removable carpets in hot water weekly, and consider using dust-mite-proof covers on pillows and mattresses. Reducing humidity with a dehumidifier can also help keep dust mite populations in check, leading to better lung health for everyone in your home.

3. Scented Candles and Air Quality

Scented candles are popular for creating a cozy, inviting atmosphere, but they can also impact indoor air quality. Many conventional candles are made from paraffin wax, which, when burned, releases volatile organic compounds (VOCs), soot, and potentially harmful chemicals like benzene and toluene into the air. According to the American Lung Association, these emissions may irritate the lungs and aggravate asthma or respiratory conditions, especially in children and older adults.

Beeswax and soy candles are considered safer alternatives, as they tend to produce fewer pollutants and burn more cleanly. Candles with natural fragrances and cotton wicks can further minimize air quality concerns.
To reduce risks, always burn candles in well-ventilated areas and avoid using them for extended periods. Consider substituting candles with flameless LED alternatives for scent and ambiance without the emissions. Regularly airing out your living space and using exhaust fans can also help disperse any lingering pollutants, keeping your home’s air cleaner and your lungs healthier.

4. Mold in Bathrooms and Basements

Mold thrives in damp, poorly ventilated spaces like bathrooms and basements, and its spores can become airborne, posing serious risks to lung health. Inhalation of mold spores can lead to respiratory symptoms such as coughing, wheezing, and shortness of breath, especially in individuals with allergies, asthma, or compromised immune systems. After hurricanes or floods, the Centers for Disease Control and Prevention (CDC) have documented increased mold growth and associated respiratory issues in affected populations.

Moisture control is the most effective way to combat mold. Use exhaust fans during and after showers, promptly repair leaky pipes, and ensure basement areas remain dry. Consider using a dehumidifier to keep humidity below 50%.
Regularly clean areas prone to dampness with mold-killing solutions and remove any visible mold promptly. If you notice a persistent musty smell, inspect hidden areas behind walls or under flooring, as mold often grows out of sight. By managing moisture, you can significantly reduce the risk of mold exposure and help protect your lungs from its harmful effects.

5. Upholstered Furniture and Chemical Off-Gassing

New sofas, chairs, and mattresses often emit a variety of chemicals in a process known as off-gassing. These emissions can include formaldehyde, benzene, and other volatile organic compounds (VOCs) used in adhesives, foams, and fabrics. Of particular concern are flame retardants—chemicals frequently added to meet fire safety standards, but which have been linked in studies to potential respiratory irritation and long-term health risks. Research published by the National Institutes of Health highlights connections between certain flame retardants and increased asthma and allergy symptoms.

To minimize exposure, air out new furniture in a well-ventilated area for several days before bringing it into your main living spaces. Opening windows and using fans can help dissipate lingering fumes.
When shopping, look for products labeled “low-VOC,” “formaldehyde-free,” or “free of added flame retardants.” Natural materials like solid wood, organic cotton, or wool are generally less likely to off-gas harmful chemicals. By being cautious about new furniture and ensuring proper ventilation, you can make your home’s décor both beautiful and lung-friendly.

6. Houseplants: Friend or Foe?

Houseplants are often praised for their ability to purify indoor air by absorbing pollutants and producing oxygen. Certain species, such as the snake plant and peace lily, have been shown to remove small amounts of VOCs from the air, according to studies cited by NASA. However, not all plants are equally beneficial, and some can introduce new respiratory risks.

Overwatering or poor drainage can lead to mold growth in soil, and flowering plants may release pollen, both of which can trigger allergies or asthma. Ferns and palms are less likely to cause pollen issues, whereas flowering varieties may be problematic for sensitive individuals.
To safely enjoy houseplants, choose non-flowering varieties if you have allergies, use well-draining pots, and avoid overwatering. Regularly remove dead leaves and check for signs of mold or mildew. With proper care and thoughtful plant selection, you can harness the air-purifying benefits of indoor greenery while minimizing any potential risks to your lungs.

7. Curtains and Drapes as Allergen Traps

Curtains and drapes, while adding style and privacy to your home, can also become significant collectors of dust, pet dander, and other airborne allergens. These particles settle easily onto soft fabrics and are easily disturbed by movement, releasing allergens back into the air and potentially triggering asthma or allergy symptoms. According to the Asthma and Allergy Foundation of America, regular cleaning of window treatments is crucial for reducing indoor allergens.

Washable curtains offer a clear advantage, as they can be laundered frequently to remove dust and allergens. In contrast, heavy or non-washable drapes often require professional cleaning and may not get cleaned as often, allowing allergens to build up.
For best results, vacuum curtains and drapes weekly using a HEPA-filter vacuum or launder them every 1-2 months. Consider replacing older, non-washable treatments with machine-washable materials or simple blinds that are easier to keep clean. By maintaining a regular cleaning routine, you can reduce allergen accumulation and help create a healthier breathing environment in your home.

8. Wood-burning Fireplaces and Particulate Matter

Wood-burning fireplaces bring warmth and ambiance, but they also release fine particulate matter (PM2.5) into the indoor air. These tiny particles can penetrate deep into the lungs and are associated with respiratory irritation, asthma flare-ups, and other lung conditions. The U.S. Environmental Protection Agency warns that wood smoke contains a mixture of harmful substances, including carbon monoxide and volatile organic compounds, which can significantly degrade indoor air quality.

Gas fireplaces, in contrast, produce far fewer particulates and are generally considered a safer option for indoor air. If you use a wood-burning fireplace, it’s crucial to keep the damper open during and after use to allow smoke to exit, and to ensure your chimney is regularly cleaned and inspected to prevent creosote buildup and blockages.
Burn only seasoned, dry wood, as burning wet or green wood increases smoke and particle emissions. Consider using air purifiers in rooms with fireplaces, and limit use during high-risk times, such as when household members have respiratory illnesses. Proper maintenance and mindful use can help minimize the impact of fireplaces on your lung health.

9. Air Fresheners and Synthetic Fragrances

Air fresheners, including sprays, plug-ins, and scented gels, are widely used to mask household odors, but many of these products release synthetic fragrances and chemicals that can irritate the respiratory tract. Studies have shown that air fresheners emit volatile organic compounds (VOCs), such as formaldehyde and phthalates, which may trigger asthma symptoms, allergic reactions, and even headaches among sensitive individuals. The Centers for Disease Control and Prevention (CDC) cautions that frequent use of such products can worsen indoor air quality, especially in poorly ventilated spaces.

Natural alternatives, like essential oil diffusers (used sparingly), fresh-cut flowers, or simply opening windows, can help freshen air without introducing as many harmful compounds. However, even some natural oils can cause issues for people with allergies or asthma, so moderation is key.
To protect your lungs, limit the use of synthetic air fresheners and ventilate rooms regularly. Choose fragrance-free or naturally scented cleaning products whenever possible. By reducing reliance on artificial fragrances, you help maintain a healthier home environment and reduce the risk of respiratory discomfort for everyone indoors.

10. Pet Dander Accumulation

Sharing your home with pets brings joy, but it can also introduce pet dander—tiny, airborne skin flakes that are a major indoor allergen. Pet dander, along with hair and saliva, can contribute to respiratory irritation and exacerbate conditions like asthma and allergic rhinitis. According to the Asthma and Allergy Foundation of America, even so-called “hypoallergenic” breeds produce dander, though pets with less fur may shed less of it.

Cats, dogs, and other furry animals differ in the amount and type of dander they produce. Cats, for example, often cause more allergic reactions due to the nature of their skin proteins. Regular cleaning is essential: bathe pets when possible, use a HEPA-filter vacuum, and wash pet bedding and covers frequently.
Limit pets’ access to bedrooms and keep them off upholstered furniture to minimize dander buildup in high-contact areas. Air purifiers can also help capture airborne dander, further reducing potential lung irritation. With diligence and good cleaning strategies, it’s possible to enjoy the company of pets while safeguarding your respiratory health.

11. Synthetic Rugs and Plasticizers

Many synthetic rugs and carpets are manufactured with plasticizers such as phthalates, which are added to increase flexibility and durability. Over time, these chemicals can off-gas or accumulate as dust, posing potential risks to respiratory health, particularly in children and those with asthma. Studies reviewed by the Centers for Disease Control and Prevention (CDC) have linked exposure to phthalates to increased asthma and allergy symptoms.

Natural fiber rugs, such as those made from wool, cotton, or jute, generally contain fewer synthetic chemicals and tend to be less problematic for indoor air quality. Synthetic carpets, on the other hand, often harbor more VOCs and may trap dust and allergens more readily.
To reduce exposure, choose rugs labeled “phthalate-free” or “low-VOC,” and allow new carpets to air out in a well-ventilated space before installing. Frequent vacuuming with a HEPA filter and occasional deep cleaning can help minimize dust and chemical buildup. Opting for natural or certified “green” rugs is a safer choice for families seeking to protect their lung health while still enjoying the warmth and comfort of soft floor coverings.

12. Dust Accumulation on Shelving and Decor

Dust that settles on shelves, picture frames, and decorative objects isn’t just unsightly—it’s a significant source of indoor allergens that can aggravate respiratory issues. Dust is a mixture of dead skin cells, fibers, pollen, and sometimes even mold spores, all of which can be inhaled and trigger symptoms like sneezing, coughing, or asthma attacks. The Asthma and Allergy Foundation of America points out that minimizing dust is critical for controlling allergies and protecting lung health.

Open shelving and exposed decor accumulate dust more quickly than closed cabinets or glass-fronted cases. For those with respiratory sensitivities, closed storage is preferable, as it helps reduce dust buildup on frequently handled or displayed items.
To keep dust at bay, dust surfaces at least once a week with a damp cloth or microfiber duster, which traps particles more effectively than dry dusting. Don’t forget to clean behind and beneath decor items as well. By staying on top of dusting routines and choosing smart storage solutions, you can make a noticeable difference in your home’s air quality and your overall lung comfort.

13. Gas Stoves and Indoor NO2

Gas stoves are a common kitchen feature, but they release nitrogen dioxide (NO₂)—a gas that can irritate the lungs and worsen respiratory conditions like asthma and chronic obstructive pulmonary disease (COPD). NO₂ exposure is particularly concerning for children and older adults, as their lungs are more sensitive to airborne irritants. Research from the U.S. Environmental Protection Agency (EPA) links indoor NO₂ from gas appliances to increased respiratory symptoms and reduced lung function.

Electric stoves do not emit NO₂, making them a safer option for indoor air quality. If you use a gas stove, proper ventilation is essential: always operate an exhaust fan that vents to the outdoors, or open a window while cooking.
Consider installing a high-quality range hood and running it during and after cooking to help remove pollutants. Regular maintenance, such as checking for leaks and keeping burners clean, can also reduce emissions. By prioritizing ventilation and exploring alternative cooking appliances, you can protect your lungs from the hidden hazards of gas stove emissions.

14. Humidifiers and Bacterial Growth

Humidifiers can make indoor air more comfortable during dry months, but if not properly maintained, they may become breeding grounds for bacteria, mold, and even fungi. When these microorganisms are dispersed into the air, they can trigger or worsen respiratory symptoms, especially in children, the elderly, and people with asthma. The Centers for Disease Control and Prevention (CDC) has highlighted outbreaks of “humidifier fever”—a form of hypersensitivity pneumonitis—linked to contaminated humidifier mist.

There are several types of humidifiers, including cool-mist, warm-mist, and ultrasonic models. Ultrasonic units, in particular, can disperse both microorganisms and minerals if not cleaned regularly.
To minimize health risks, empty and rinse the tank daily, and disinfect the unit with a mild bleach solution at least once a week. Use distilled or demineralized water to prevent mineral buildup. Replace filters as recommended by the manufacturer. By following these cleaning best practices, you can safely enjoy the benefits of a humidifier without compromising your lung health.

15. Old Books and Paper Dust

Treasured collections of old books can contribute to indoor air pollution through the release of paper dust and mold spores. As books age, their paper fibers break down, creating fine dust that becomes airborne with handling or cleaning. In damp or poorly ventilated areas, books are also prone to mold growth, which can lead to musty odors and respiratory irritation—especially for those with allergies or asthma. The National Institutes of Health (NIH) has linked exposure to mold and paper dust in libraries and homes with increased respiratory symptoms.

Storing books in sealed bookcases or cabinets helps limit dust and mold spread compared to open shelving. Regular dusting with a soft cloth or vacuuming with a HEPA-filter attachment can remove surface particles.
To prevent mold, keep books in dry areas with humidity below 50%, and use silica gel packs or dehumidifiers if needed. If books develop visible mold, isolate and clean them outdoors when possible. By combining proper storage and regular maintenance, you can enjoy your library while reducing potential risks to your lungs.

16. Lead Paint in Older Homes

Many homes built before 1978 contain lead-based paint, which can pose serious health risks when it deteriorates or is disturbed during renovations. Lead dust or chips can become airborne and be inhaled, leading to lung irritation and—more critically—lead poisoning, which is especially dangerous for children and pregnant women. The U.S. Environmental Protection Agency (EPA) warns that even small amounts of lead dust can impact respiratory and neurological health.

Modern housing standards prohibit the use of lead in residential paints, making newer homes much safer in this regard. If you live in or plan to purchase an older home, it’s important to test for lead before beginning any renovation project.
For safe removal, hire certified lead abatement professionals who follow EPA guidelines to minimize dust and prevent contamination. Never sand, scrape, or heat old paint without proper containment and protective equipment. By understanding the risks and taking appropriate precautions, you can update your living space while protecting your family’s lung health from legacy hazards.

17. Vinyl Flooring and Chemical Emissions

Vinyl flooring is popular for its durability and affordability, but it can release volatile organic compounds (VOCs) such as phthalates and formaldehyde through a process called off-gassing. These chemical emissions may linger for weeks or even months after installation, contributing to poor indoor air quality and potentially irritating the lungs, especially in children and sensitive individuals.

20. Attic Insulation and Asbestos

Many homes built before the 1980s were insulated with materials containing asbestos, a mineral fiber now known to cause severe lung diseases, including asbestosis and mesothelioma, when inhaled. Disturbing old attic insulation—for example, during renovations or repairs—can release microscopic asbestos fibers into the air, where they can be easily inhaled and pose a serious health threat. The U.S. Environmental Protection Agency (EPA) warns that there is no safe level of asbestos exposure.

Modern fiberglass insulation is widely used today and, while it can cause minor irritation if handled improperly, does not carry the same long-term respiratory risks as asbestos.
If you suspect your attic contains asbestos-based insulation, never attempt to remove or disturb it yourself. Instead, hire a licensed asbestos abatement professional who can safely assess and remediate the hazard following strict safety protocols. Sealing off affected areas and wearing appropriate personal protective equipment is essential. By recognizing the risks and following proper abatement steps, you can safeguard your home’s air quality and protect everyone’s lungs from this silent danger.

21. Scented Laundry Products

Many popular laundry detergents, fabric softeners, and dryer sheets contain synthetic fragrances that can contribute to indoor air pollution. As clothes are washed and dried, volatile organic compounds (VOCs) from these fragrances are released into the air, where they can be inhaled and potentially irritate the lungs or trigger allergies, especially in sensitive individuals. According to research from the National Institutes of Health (NIH), some scented laundry products emit hazardous air pollutants even after the laundry is dry.

Fragrance-free or “free and clear” laundry products are less likely to emit VOCs, making them a healthier choice for those concerned about respiratory health. Natural alternatives, such as using baking soda or white vinegar as fabric softeners, can also help minimize indoor air pollution.
To further reduce exposure, air-dry laundry outdoors when possible and avoid heavily scented dryer sheets and softeners. By choosing fragrance-free options and ventilating your laundry area, you can help protect your lungs while still enjoying clean, fresh-smelling clothes.

To minimize risks, use pesticides only as directed, ventilate the area thoroughly, and keep children and pets away until surfaces are dry and fumes have dissipated. Whenever possible, opt for integrated pest management strategies that focus on prevention and non-toxic control. By being mindful of your pest-control choices and usage habits, you can keep your home both pest-free and lung-friendly.

23. Clutter and Limited Air Circulation

Cluttered rooms not only make your home feel cramped but can also restrict airflow and create pockets where dust and allergens accumulate. Overfilled shelves, piles of belongings, and crowded corners impede natural air movement, leading to stagnant areas where dust mites, mold spores, and other irritants thrive. The Asthma and Allergy Foundation of America emphasizes the importance of good air circulation in managing indoor allergens and maintaining lung health.

Minimalist spaces—with fewer items and open layouts—allow for better airflow, easier cleaning, and less dust buildup compared to cluttered environments.
To declutter effectively, tackle one area at a time, sorting items into categories like “keep,” “donate,” or “discard.” Use storage solutions such as bins or cabinets to reduce exposed surfaces. Regularly dust and vacuum cleared spaces to prevent allergen accumulation. By simplifying your décor and maintaining open, breathable rooms, you not only create a more inviting living space but also support healthier air quality for your lungs.

24. Synthetic Bedding and Allergens

The type of bedding you choose can significantly impact indoor air quality and respiratory comfort. Synthetic bedding materials, such as polyester and certain memory foams, tend to trap dust mites, pet dander, and other allergens more readily than natural fibers. Over time, this can worsen allergy and asthma symptoms, particularly for those with sensitive lungs. The Asthma and Allergy Foundation of America highlights bedding as a key site for allergen accumulation in the home.

Cotton and other natural fibers are more breathable and less likely to retain moisture, reducing the likelihood of dust mite and mold growth compared to synthetic options. Hypoallergenic bedding—such as dust-mite-proof covers and pillows—can further protect against allergen buildup.
Wash sheets, pillowcases, and blankets weekly in hot water to kill dust mites and remove allergens. Consider replacing old bedding with hypoallergenic, easily washable materials, and avoid heavy comforters that are difficult to clean. By making thoughtful bedding choices, you can create a healthier sleeping environment and reduce nighttime respiratory irritation.

25. Air Conditioning Units and Mold

Air conditioning units, if not properly maintained, can become a hidden source of mold and bacteria in your home. Moisture collects in AC coils and drip pans, creating a prime environment for mold growth, which can then be blown into the air and inhaled. The U.S. Environmental Protection Agency (EPA) warns that mold exposure can trigger allergies, asthma attacks, and other respiratory symptoms.

Central air systems tend to circulate contaminants throughout the entire house, while window units may affect just one room but can be harder to clean thoroughly.
To prevent mold buildup, clean or replace air filters every 1-3 months, check drip pans regularly, and ensure proper drainage. Schedule professional maintenance for central air systems at least once a year, and clean window units thoroughly at the start and end of each cooling season. Keeping humidity levels below 50% also helps limit mold growth. By following these maintenance routines, you can ensure your AC system supports—not undermines—your respiratory health.

26. Nonstick Cookware and Fumes

Nonstick cookware, especially pans coated with polytetrafluoroethylene (PTFE), can release toxic fumes when overheated. At high temperatures, the coating can break down and emit gases that may cause flu-like symptoms known as “polymer fume fever,” and potentially irritate the lungs. The Agency for Toxic Substances and Disease Registry (ATSDR) notes that these fumes are especially concerning for people with respiratory sensitivities and for pet birds, which are highly susceptible to airborne toxins.

Stainless steel, cast iron, and ceramic cookware do not emit fumes at high temperatures and are considered safer for lung health. If you use nonstick pans, never heat them empty or above medium temperatures, and avoid using damaged or scratched cookware.
Always cook in a well-ventilated kitchen—use exhaust fans or open windows to disperse any fumes. Consider gradually switching to safer cookware materials for routine use.

The American Academy of Allergy, Asthma & Immunology (AAAAI) notes that essential oil vapors have been linked to respiratory symptoms, particularly in sensitive populations.

Some oils—such as eucalyptus, peppermint, and tea tree—are more likely to provoke symptoms than gentler options like lavender or chamomile.
To reduce risk, always use essential oils in moderation and choose high-quality, pure varieties with minimal additives. Run diffusers for short periods in well-ventilated rooms, and avoid use entirely if you or family members experience coughing, wheezing, or throat irritation. For individuals with chronic lung conditions, it may be best to skip diffusers altogether and opt for other methods of air freshening. With a careful approach, you can balance the benefits and risks of essential oils in your home environment.

29. Damp Basements and Radon

Basements, especially damp or poorly ventilated ones, can harbor radon gas—a naturally occurring radioactive gas that is the second leading cause of lung cancer in the United States after smoking. Radon seeps into homes through cracks in floors, walls, and foundations, and tends to accumulate in lower levels like basements. The U.S. Environmental Protection Agency (EPA) warns that radon levels can vary significantly by region, with some areas of the country at much higher risk.

Homes in the Midwest, Northeast, and Appalachian regions often have higher radon concentrations due to local geology. Regardless of location, any home can have elevated radon, making testing essential.
Radon test kits are affordable and widely available; place them in the lowest lived-in level of your home for accurate results. If high levels are detected, certified mitigation professionals can install ventilation or sealing systems to reduce risk. Regular testing, especially after home renovations or foundation repairs, is a crucial step in protecting your lungs from this invisible hazard.

30. Mattresses and Flame Retardants

Mattresses sold in the United States have long been required to meet flammability standards, leading many manufacturers to use flame retardant chemicals in foams and fabrics. Older mattresses, in particular, often contain chemicals such as polybrominated diphenyl ethers (PBDEs), which can off-gas into your bedroom air and have been linked to respiratory irritation and other health concerns. Research summarized by the Centers for Disease Control and Prevention (CDC) points to connections between flame retardant exposure and increased asthma symptoms.

In recent years, regulations have shifted: many newer mattresses use safer alternatives, such as wool or silica barriers, instead of chemical flame retardants.
When shopping for a mattress, look for certifications like CertiPUR-US or GREENGUARD Gold, which indicate low chemical emissions and the absence of certain flame retardants. Allow any new mattress to air out in a well-ventilated space for several days before use, and consider organic or natural-fiber mattresses if you have chemical sensitivities.

Rural areas often have cleaner air, while urban environments may experience higher levels of smog, pollen, and particulate matter from vehicles and industry. The U.S. Environmental Protection Agency (EPA) regularly monitors regional air quality and provides up-to-date information on pollution levels.

Ventilating at the right time is key: open windows during periods when outdoor air quality is good—typically early morning or after rainfall in cities—and keep them closed during high-traffic hours or on days with air quality alerts.
If you live near farms or forests, be mindful of pollen or agricultural chemicals, which can also affect air quality. Use air quality apps or websites to track local conditions and plan ventilation accordingly. By timing window openings strategically, you can enjoy the benefits of fresh air while minimizing exposure to outdoor pollutants that could affect your lung health.

35. DIY Scented Sachets

Homemade scented sachets are a popular way to freshen closets and drawers, but they can introduce allergens into your living space depending on the ingredients used. Dried flowers, herbs, and essential oils commonly found in sachets may release pollen, mold spores, or strong fragrances that can trigger allergic reactions or respiratory symptoms in sensitive individuals. The American Academy of Allergy, Asthma & Immunology (AAAAI) notes that botanicals, while natural, are still potential allergens.

Comparing ingredients, lavender and chamomile are gentler options, while rose petals or certain herbs may be more likely to aggravate allergies.
For a hypoallergenic approach, use unscented cotton, rice, or baking soda inside sachets to absorb odors without adding irritants. If you prefer fragrance, opt for a drop or two of hypoallergenic essential oil on a cotton ball rather than using dried botanicals. Replace sachet contents regularly to prevent mold growth. By selecting ingredients with care, you can enjoy the freshness of homemade sachets without compromising your lung health.

36. Candles with Metal-Core Wicks

Some older candles and imported varieties use metal-core wicks, which can emit heavy metals such as lead when burned. Inhaling lead particles, even in small amounts, can pose serious risks to lung and overall health—especially for children and pregnant women. The U.S. Consumer Product Safety Commission (CPSC) banned the sale of candles with lead-core wicks in 2003, but older or non-U.S. candles may still pose a danger.

Modern candles typically use cotton or paper wicks that do not release heavy metals, making them much safer for indoor air quality.
When purchasing candles, check labels or ask manufacturers about wick materials, and avoid using vintage or unmarked candles. Opt for products from reputable brands that comply with safety regulations. If in doubt, trim the wick before lighting and watch for any metallic bead or wire in the core. By being a discerning shopper and favoring candles with natural wicks, you can enjoy candlelight ambiance without exposing your lungs to unnecessary toxins.

37. Particle Board Furniture

Many modern furnishings are made from particle board or other composite woods, which often contain adhesives that release formaldehyde, a volatile organic compound (VOC) known to irritate the lungs and exacerbate asthma. Formaldehyde emissions are most pronounced when furniture is new and can linger for months, affecting indoor air quality. The U.S. Environmental Protection Agency (EPA) has classified formaldehyde as a probable human carcinogen and recommends limiting exposure, especially in spaces where children and sensitive individuals spend time.

Solid wood furniture generally emits fewer VOCs, making it a safer option for those concerned about lung health.
To reduce off-gassing from particle board, allow new furniture to air out in a well-ventilated area before regular use. Keeping indoor humidity low and using air purifiers can also help disperse fumes. Look for products labeled “CARB Phase 2 Compliant” or “formaldehyde-free” to ensure lower emissions. By choosing solid wood or certified low-emission composite furniture, you can enjoy stylish décor without compromising your respiratory health.
