Health experts warn about dangers of scented candles
In this DML Report…
Scented candles, particularly those made from paraffin wax, release harmful compounds during combustion, including alkanes and alkenes similar to those in car exhaust, as well as gases like carbon monoxide and nitrogen oxide. Synthetic fragrances in these candles often contain phthalates, which act as endocrine disruptors and can lead to hormone imbalances. Prolonged exposure in poorly ventilated spaces may contribute to respiratory irritation, headaches, and increased risks of respiratory issues or cancer. Additional emissions include polycyclic aromatic hydrocarbons (PAHs) such as naphthalene, anthracene, and pyrene, identified as carcinogens originating from the wax, aroma substances, or dyes used in the candles. Common symptoms from exposure include vertigo, mucosa irritation, watery eyes, sneezing, stuffy nose, chest tightness, and dry or irritated throat.
Wellness expert Peter Spiegel, CEO of AirDoctor, notes that paraffin-based scented candles can significantly degrade indoor air quality due to these emissions and recommends avoiding them to protect users, children, and pets. Dr. Paul Savage, Chief Medical Officer at MDLifespan and a toxin expert, confirms that certain candle fumes pose health risks including respiratory problems and potential cancer links, though not all candles present the same issues. A study published in the National Library of Medicine reports that indoor burning of scented candles releases these harmful gases, contaminating the environment and leading to the listed health effects.

Safer options include candles made from natural waxes such as soy, coconut, or beeswax, scented with pure essential oils instead of synthetic fragrances, which produce fewer harmful emissions. Experts advise ensuring proper ventilation in rooms where candles are burned and limiting their use to minimize exposure to any potential toxins.
