Scented candles have long been used to create cozy and romantic atmospheres at home, yet they may carry hidden health risks, according to the Environmental Protection Agency (EPA).

Burning scented candles, especially those made from paraffin wax derived from petroleum, releases volatile organic compounds like benzene and toluene, which can irritate the respiratory system and cause headaches or dizziness with prolonged exposure.

The danger extends beyond emitted gases, as candles with metal-core wicks release fine particles known as “PM2.5” that penetrate deep into the lungs, potentially causing chronic respiratory inflammation.

Artificial fragrances add to the risk, often containing phthalates, chemicals that can disrupt hormones and irritate the respiratory system, particularly affecting children and the elderly.

Experts recommend using soy or beeswax candles and opting for natural or fragrance-free scents to reduce exposure to harmful chemicals while still enjoying the calming effects of candles safely.
