Scented candles are favored aroma therapy that adds a comfortable and luxurious atmosphere. Their gentle glow and soothing aromas transport individuals to a place of calm, providing a necessary escape from daily life’s hustle and bustle. However, an important question arises: How do these fragrant products affect the air we breathe?
With increased indoor time, especially in recent periods, the quality of our indoor environment is of utmost importance. Consumers are becoming increasingly discerning, seeking not only luxury but also ensuring their indulgences do not compromise their health or the planet’s future.
How Do Scented Candles Impact Air Quality?
When a candle is lit, it releases more than just a soothing aroma into the room. There is a complex science behind what gets emitted into the air:
· Release of Hydrocarbons: When burned, candles emit hydrocarbons, including trace amounts of toluene and benzene. These compounds can contribute to indoor air pollution and have various health implications. The Cleveland Clinic provides a comprehensive analysis of these hydrocarbons and their potential effects.
· Particulate Matter: Especially in candles made of paraffin, fine particulate matter is released into the air. These tiny particles can be inhaled deep into the lungs, potentially causing respiratory issues over time. The EPA has conducted extensive research on this topic, emphasizing the importance of understanding the candles we use. Plug in an air particulate monitor that we have tried with the many tests we performed.
· Lead and Metal-Core Wicks: Some candles, particularly older ones, have wicks containing lead or other metals. When burned, these can release harmful emissions. It is crucial to be aware of this when purchasing candles from unknown sources or older stock. Choose candles with cotton eco wicks.
Choosing the Right Candles for Better Air Quality
Not all candles are created equal. Here is how to make informed decisions:
· Opt for natural waxes like beeswax, soy, and other plant-based waxes that produce fewer emissions than paraffin. They also tend to burn cleaner, offering a more eco-friendly option. The Guardian offers a detailed examination of the benefits of these natural waxes.
· Avoid dyes that contain chemicals. Some candle dyes can release additional toxins when burned. Choosing dye-free candles can reduce the risk of inhaling these chemicals.
· Check the wick to ensure your candles have cotton, wood, or paper-core wicks. Avoid those with metal cores, as highlighted by the Cleveland Clinic, to ensure a safer burning experience.
Health Implications of Burning Scented Candles
While occasional candle use might not pose a significant risk, frequent use can have health consequences:
· Respiratory Concerns: The particulate matter from candles can irritate the respiratory system, particularly in those with pre-existing conditions. This is especially concerning for individuals with asthma or chronic respiratory conditions.
· Allergic Reactions: Some individuals may experience allergies or asthma attacks from scented candles. It is essential to be aware of the ingredients in your candles, particularly if you have known sensitivities.
· Potential Cancer Risk: Though evidence is inconclusive, some research suggests a link between frequent candle burning and certain cancers. For example, see this study on PubMed.
Tips for a Healthier Candle Experience
For those who enjoy candles but want to ensure a healthy environment:
· Always ensure good ventilation when burning candles. This helps disperse pollutants and keeps the air fresh. Open the window where the candle is burning.
· Avoid burning candles for extended periods. Aim for a maximum of four hours at a stretch to reduce the amount of pollutants released.
· Regularly trim the wick. A shorter wick produces a cleaner burn, reducing soot and emissions. If you are seeing dark spots in your ceiling it may be caused by candle soot.
Making Informed Choices with Candles
Scented candles hold a special place in our hearts and homes. However, it is essential to strike a balance between ambiance and air quality. Knowledge is the first step towards making informed choices that prioritize both luxury and health.
