While incense and candles are often used as a decorative element in the home, they can also be an important component of spiritual or meditation practices. They may also help create a more pleasant environment for relaxing or entertaining guests. However, their use isn’t without some drawbacks, particularly in relation to indoor air quality. The burning of these products releases fine particulate matter, volatile organic compounds (VOCs), and other harmful chemicals that can aggravate respiratory conditions like asthma or bronchitis and even pose carcinogenic risks over time. The risk is exacerbated in well-sealed and insulated homes during the winter, where reduced ventilation allows these pollutants to accumulate to dangerously high levels.
The manufacture of incense and candles contributes to environmental degradation through energy-intensive processes that emit greenhouse gases as well as other pollutants. The sourcing of raw materials, such as the use of palm oil in many candle formulations, can lead to deforestation and habitat destruction if not harvested sustainably. Furthermore, the disposal of these products contributes to landfill waste. These issues may not always be apparent when using incense or candles, but regular and prolonged exposure can have long-term negative impacts on indoor air quality.
During the combustion process, both incense and candles release various VOCs as well as fine particulate matter that can penetrate deeply into the lungs and enter the bloodstream. Some of these pollutants, such as benzene and formaldehyde, have been known to cause cancer over time. Furthermore, the odors emitted by some candles and incense products can trigger allergic reactions in sensitive individuals.
There are a number of ways that people can minimize their exposure to the smoke and chemicals released by incense and candles. For example, choosing products that use natural fragrances and avoid the use of synthetic chemicals is an effective way to reduce these concerns. Additionally, regularly trimming wicks to prevent soot formation and burning candles in a well-ventilated space can significantly reduce the release of contaminants.
Ultimately, the most effective way to protect against the effects of incense and candles is to limit their use and to choose options that are as environmentally sustainable as possible. In the case of candles, selecting those made from a natural wax such as soy or beeswax is preferable to paraffin waxes, which contain fossil fuel byproducts. Similarly, opting for incense made from botanical ingredients rather than those that are formulated with chemical fragrances is another good choice. In addition, keeping the windows and doors closed as much as possible during use helps prevent indoor pollutants from dispersing. Finally, ensuring that both incense and candles are extinguished completely after burning is an easy way to reduce the likelihood of adverse health effects.
