What are the health and safety concerns associated with commercial candles?

Commercial candles, particularly those made from paraffin wax, present several health risks when burned indoors.

It has been found that these candles release a range of toxic substances including benzene, toluene, and formaldehyde upon combustion. Additionally, they produce ultrafine particles that can penetrate the respiratory system and potentially enter the bloodstream, leading to various health problems such as inflammation and oxidative stress.

• Conventional scented candles often contain undisclosed fragrances that may include harmful compounds.
• The wax used in many candles may contain carcinogens, raising significant concerns about their safety during use.
• Alternative options, such as beeswax candles, can reduce chemical exposure significantly, especially when wicks are made from cotton or wood.

Awareness of the potential health risks associated with the burning of commercial candles necessitates a shift towards safer alternatives to protect indoor air quality and overall health.
