The Following is a Google AI-assisted overview, of the 'Candles & Health' topic - November 2025
Burning candles, especially scented ones made with paraffin wax, can release indoor air pollutants like particulate matter, volatile organic compounds (VOCs), and chemicals such as formaldehyde and toluene, which can cause respiratory problems like asthma, headaches, and allergic reactions.
The risk is higher for those with existing respiratory conditions, and proper ventilation is crucial to minimise exposure.
Choosing candles made with natural waxes like soy or beeswax and using them in moderation can help reduce potential harm, along with frequent ventilation and air purification.
