Room fresheners are commonly used to make homes, offices and cars smell pleasant. But frequent use, especially in poorly ventilated spaces, may expose you to chemicals that can irritate the eyes, nose and throat and may trigger discomfort in some people.
A pleasant fragrance can instantly make a room feel cleaner and fresher, which is why room freshener sprays are widely used in homes, workplaces and cars. However, the fragrance does not actually remove every source of bad indoor air. Instead, sprays release fragrance compounds into the surrounding air, where they can remain for some time.
For most people, occasional exposure may not cause a noticeable problem. However, repeated or heavy exposure can be uncomfortable, particularly for children, older adults and people who are sensitive to strong fragrances or already have respiratory problems.
Room fresheners can contain several fragrance-producing chemicals. These may include volatile organic compounds, commonly known as VOCs, as well as other substances such as dichlorobenzene in some products.
When a spray is released, these substances can disperse into the air as tiny particles or vapours. We can then inhale them along with the surrounding air.
The effect can vary from person to person. However, exposure to high concentrations may irritate the eyes, nose and throat. Some people may also experience symptoms such as headache, dizziness or a feeling of discomfort.
Using a strong fragrance spray in a closed room can increase exposure because there is less fresh air to dilute the chemicals.
People with existing breathing problems may be particularly sensitive to strong fragrances. Children and older adults can also experience greater discomfort in some situations.
This does not mean that every room freshener will cause illness or that occasional use is necessarily harmful. The amount used, frequency of exposure, ventilation and individual sensitivity all matter.
One of the simplest precautions is to maintain proper airflow when using a spray. Opening windows or doors can help improve ventilation and reduce the concentration of airborne fragrance compounds.
Instead of repeatedly spraying a room throughout the day, identify and remove the source of the unpleasant smell wherever possible. Regular cleaning, proper waste disposal and keeping damp areas dry can often help control indoor odours.
If you choose to use a room freshener, avoid spraying it directly near your face or in large quantities. Do not deliberately inhale the spray, and keep such products away from children and pets.
People who notice headaches, eye irritation, coughing, throat irritation or breathing discomfort after using a particular fragrance should stop using it and get fresh air.
It is also worth remembering that a strong fragrance does not necessarily mean cleaner air. In closed spaces, good ventilation and controlling the source of an odour are more useful long-term measures.
