Scented candles might be harmful in following ways:
INDOOR AIR POLLUTION
Though they seem safe but regular scented candles are a huge source of indoor air pollution and they put off chemicals that are considered just as dangerous as second-hand smoke.
A 2009 study in South Carolina State University also warns about chemicals released into the air upon burning candles. Researchers found that burning some candles produced “undesired chemicals,” like alkans, alkenes, and toluene, which have harmful effects on our health.
For everyone who lights a candle every day for years or just uses them frequently, inhalation of these dangerous pollutants wandering in the air could contribute to the development of health risks like common allergies and even asthma,
Some researchers also worry about the long-term effects of using scented candles that these fresheners can contain “considerable levels of formaldehyde” which could cause cancerous DNA mutations.
On top of that, many scented candles also have wicks that contain heavy metals like lead, and even a few hours of burning them can create levels of airborne heavy metals that are much higher than the acceptable limits which can also cause tumors, lungs damage, asthma and in extreme cases cause cancer.
