Fresh or Fatal: How Fragrances in the Products You Use Every Day Could Be Making You Sick
Fragrances are everywhere—from the soap we use in the morning to the air fresheners that promise to make our homes smell delightful. Most people associate these scents with cleanliness, freshness, and comfort. But behind the allure of pleasant aromas lies a hidden truth that many are unaware of: the synthetic fragrances found in everyday products may not only be harmful but potentially hazardous to your health. As a building biologist, my aim is to shed light on how these invisible chemicals may be polluting your indoor environment and negatively impacting your well-being.
The Rise of Fragrance in Everyday Products
In today’s world, fragrances are added to a broad range of household products, from cleaning supplies and laundry detergents to personal care items like shampoo, body lotion, and deodourant. While these products often promise to elevate your sensory experience, they are loaded with synthetic chemicals designed to mimic natural scents. These compounds are often hidden behind the term “fragrance” or “parfum” on ingredient labels, a catch-all term that can contain up to hundreds of individual chemicals.
Why Fragrances are Potentially Fatal to our Health
Here are ten toxic chemicals commonly found in fragranced products, which, over time, may contribute to a range of health problems:
1. Phthalates
Used to make fragrances last longer, phthalates are endocrine disruptors that interfere with hormone systems. Prolonged exposure has been linked to reproductive issues, asthma, and allergies.
2. Formaldehyde
A common preservative in scented products, formaldehyde is classified as a human carcinogen. Exposure, especially indoors, can irritate the eyes, nose, and throat and has been associated with an increased risk of cancer.
3. Benzene
Found in some air fresheners, benzene is another carcinogen. Inhalation can lead to dizziness, headaches, and, in long-term cases, harmful effects on bone marrow, potentially resulting in leukemia.
4. Synthetic Musks
Synthetic musks, used in many personal care items, can accumulate in human tissue and disrupt hormone function. Research suggests they may also harm aquatic life, leading to environmental concerns.
5. Limonene
Often used in citrus-scented products, limonene reacts with ozone in the air to form formaldehyde and other harmful substances. Inhalation can trigger respiratory issues.
6. Styrene
A chemical commonly used in the manufacture of plastics, styrene is also found in some fragranced products. Classified as a probable carcinogen, styrene exposure can lead to headaches, fatigue, and memory impairment.
7. Toluene
This chemical, often found in nail polishes and paints, can negatively affect the nervous system. Inhalation of toluene can lead to dizziness, nausea, and even more severe neurological issues with prolonged exposure.
8. Methanol
A solvent used in many cleaning products and fragrances, methanol can be absorbed through the skin or inhaled. Chronic exposure may result in vision problems, headaches, and damage to the liver.
9. Parabens
Although used as preservatives, parabens are known hormone disruptors that can mimic estrogen in the body. Prolonged exposure has been linked to an increased risk of breast cancer and reproductive harm.
10. Volatile Organic Compounds (VOCs)
These gases, emitted from many fragranced products, can cause short-term health effects like headaches and nausea. Long-term exposure may contribute to liver damage, kidney damage, and central nervous system issues.

How Fragrances Affect Indoor Air Quality
From a building biology perspective, indoor air quality is of utmost importance. The fact that we spend around 90% of our time indoors means that the air we breathe at home or work significantly influences our health. Fragrances contribute to indoor air pollution through volatile organic compounds (VOCs), which off-gas into the air and linger in enclosed spaces.
When you use scented products like air fresheners, candles, or even scented laundry detergents, you may unintentionally release harmful chemicals into your home. The problem worsens in modern, well-insulated homes that are tightly sealed for energy efficiency but trap indoor pollutants. Over time, continuous exposure to these synthetic chemicals can lead to “sick building syndrome,” where occupants suffer from headaches, dizziness, respiratory issues, and fatigue.
Fresh Alternatives: Choosing Non-Toxic, Natural Products
So, how do you avoid these toxic chemicals while still maintaining a fresh, clean home? It starts with awareness and a shift toward natural, non-toxic alternatives. Here are several “fresh” alternatives you can incorporate into your home:
1. Essential Oils
Unlike synthetic fragrances, essential oils are derived from plants and can offer therapeutic benefits without harmful chemicals. Look for 100% pure essential oils and avoid products labeled as “fragrance oils,” which often contain synthetic components.
2. Unscented or Fragrance-Free Products
Many personal care and cleaning products now offer unscented or fragrance-free options. These products are less likely to contain the harmful chemicals associated with synthetic fragrances.
3. DIY Cleaning Solutions
Consider making your own cleaning products using simple ingredients like baking soda, vinegar, and essential oils. Not only are these natural alternatives safer, but they’re also more cost-effective.

4. Natural Candles
Avoid paraffin wax candles, which can release harmful chemicals when burned. Instead, opt for soy or beeswax candles scented with natural essential oils.
5. Open Windows for Fresh Air
Rather than relying on air fresheners, open windows to let fresh air circulate and remove indoor pollutants. Good ventilation is essential for maintaining healthy indoor air quality.
6. Houseplants for Natural Air Purification
Certain houseplants, such as spider plants, peace lilies, and snake plants, are known for their air-purifying abilities. Incorporating greenery into your home can naturally improve air quality.
7. Natural Soaps and Detergents
Look for personal care products and laundry detergents labeled as “fragrance-free” or containing natural scents derived from essential oils. These products are less likely to contain synthetic chemicals.
8. Vinegar and Lemon for Odour Neutralisation
Instead of masking odours with chemical-laden air fresheners, use natural odour neutralisers like vinegar and lemon. These work just as effectively without introducing toxins into your environment.
9. Natural Deodorants
Switch to deodorants that use baking soda, coconut oil, and essential oils instead of synthetic fragrances. Many natural brands offer effective alternatives without harmful chemicals.
10. Natural Fabric Softeners
Ditch the synthetic fragrance-loaded dryer sheets in favor of wool dryer balls. These can help soften fabrics and reduce static without adding toxins to your clothes.
The Impact of Fragrances on Sensitive Populations
Fragrances can be especially harmful to vulnerable populations, such as children, pregnant women, and individuals with asthma or chemical sensitivities. Children are more susceptible to toxic exposures due to their developing immune systems, while pregnant women may inadvertently expose their unborn children to harmful chemicals. If anyone in your household suffers from respiratory conditions, fragranced products can exacerbate symptoms, leading to further health issues.
Final Thoughts
Fragrances in everyday products are often overlooked as a source of indoor air pollution and potential health hazards. The rise of synthetic chemicals used in scented products has created a hidden risk in our homes and workplaces, with dangerous consequences for our well-being. By understanding the impact of fragrances and choosing natural, non-toxic alternatives, you can create a fresher, healthier environment for yourself and your loved ones.
