What You'll Learn
The dangers of scented candles
Scented candles are a popular way to create a cosy atmosphere and fill your home with fragrance. However, there are concerns about the potential health risks associated with burning scented candles, particularly those made from paraffin wax.
Paraffin wax is a by-product of petroleum, and burning it releases potentially harmful chemicals such as volatile organic compounds (VOCs) and phthalates. VOCs are carbon compounds that easily turn into gas at room temperature. While some VOCs occur naturally in flowers, others like formaldehyde and benzene are potentially carcinogenic. Phthalates have been linked to a range of issues, including learning and behavioural problems, obesity, impaired reproductive development, and endocrine disruption.
In addition to the risks posed by paraffin wax, scented candles often contain artificial fragrances and colourants that can contribute to indoor air pollution. Burning scented candles indoors has been shown to increase levels of pollutants such as formaldehyde, CO2, and VOCs. The risk of toxic emissions is greater when candles are scented or dyed, and these chemicals can be especially harmful to vulnerable individuals with respiratory issues such as asthma.
While the research on the health effects of scented candles is mixed, and some argue that the levels of toxins are not high enough to pose a significant health threat, it is advisable to take precautions when using scented candles. To minimise the risk of exposure to harmful chemicals, choose candles made from natural, clean ingredients such as beeswax or soy wax, and avoid burning candles in poorly ventilated spaces. Additionally, ensure that you air the room after extinguishing a candle to get rid of any chemical compounds produced during burning.
Overall, while scented candles can enhance the ambiance and fragrance of your home, it is important to be aware of the potential dangers and take steps to minimise any possible health risks associated with their use.

Are natural wax and fragrances safer?
There is some debate about whether burning candles is bad for your health. Some people claim that candles release potentially harmful toxins. However, people on the other side of the argument say that candles do not contain enough toxins to pose a significant health threat.
Natural fragrances are generally considered safer than synthetic fragrances. Natural fragrances are derived from essential oils and botanical extracts, while synthetic fragrances are created in a lab and may contain potentially harmful chemicals such as phthalates and parabens.
One issue with synthetic fragrances is that they may contain high levels of chemicals that are not naturally present in the ingredient they are trying to replicate. These chemicals can cause allergic reactions, photosensitivity, or even have carcinogenic effects on the body. However, it is important to note that natural fragrances can also contain harmful chemicals, especially if they are not properly disclosed by the manufacturer.
In terms of wax, candles made from natural waxes such as beeswax, soy wax, or palm wax are generally considered safer than those made from paraffin wax, which is derived from petroleum. Natural wax candles produce less soot and release fewer dangerous chemicals when burned. However, it is important to ensure that natural wax candles are made with quality ingredients, as low-quality natural waxes can contain impurities that may be harmful.
Overall, while natural wax and fragrances are generally safer than their synthetic counterparts, it is important to be mindful of the potential risks associated with any type of candle and take steps to minimize exposure to potentially harmful chemicals, such as ventilating the room when burning candles and choosing candles with natural ingredients.

Burning candles and fire safety
While candles create a beautiful ambiance and can be used for decoration, in ceremonies, and to release fragrances, they are a potential fire hazard if not carefully monitored. Here are some fire safety tips to keep in mind when burning candles:
Never leave a burning candle unattended: Always ensure that a burning candle is within your sight. This way, you can keep a close eye on it and quickly respond to any potential issues.
Keep candles away from flammable objects: Place candles on a heat-resistant surface, such as a sturdy candleholder, and keep them away from furniture, drapes, bedding, carpets, books, paper, and flammable decorations. A safe distance of at least three inches should be maintained between burning candles to prevent them from melting each other or creating drafts that could cause improper burning.
Keep candles out of reach of children and pets: Ensure that children and pets cannot reach or knock over burning candles. Place them in safe locations, out of their curious hands and paws.
Trim the wick: Before lighting a candle, trim the wick to a length of about ¼ inch. Long or crooked wicks can lead to uneven burning, dripping, or flaring.
Avoid drafts and vents: Burning candles near drafts, vents, or air currents can cause rapid or uneven burning, excessive dripping, and sooting.
Discontinue burning a candle when it's low: Do not burn a candle all the way down. For safety, stop burning when about ½ inch of wax remains in a container candle or 2 inches for a pillar candle.
Extinguish unstable flames: If a candle's flame becomes too high or flickers repeatedly, extinguish it, let it cool, trim the wick, and check for drafts before relighting.
In addition to fire safety, it is worth considering the potential health impacts of burning candles. While there is ongoing debate about the extent of the harm, it is generally acknowledged that burning candles, especially those made of paraffin wax, can release potentially harmful chemicals such as volatile organic compounds (VOCs) and phthalates. These compounds are also present in everyday air pollution from car exhaust and factory emissions. To minimize potential negative health effects, opt for candles made from natural ingredients, such as beeswax, soy wax, or palm wax, and always burn candles in a well-ventilated area. Battery-operated flameless candles are another option to consider if you want to avoid the potential risks associated with burning candles while still enjoying their ambiance.

Paraffin wax and its health effects
Paraffin wax is a common ingredient in candles due to its low cost and ability to burn well. It is derived from petroleum, coal, or shale oil, which are by-products of gasoline production. However, burning paraffin wax releases potentially harmful chemicals, including volatile organic compounds (VOCs) and phthalates. VOCs are carbon compounds that easily turn into gases at room temperature, and some, like formaldehyde and benzene, are known carcinogens. While an older study from 2014 found that the amount of particulate matter released from burning candles was not enough to cause health issues, there is still concern that extended exposure to particulate matter can lead to heart and lung problems.
Some people experience headaches, nausea, and asthma attacks when burning paraffin wax candles, which may be due to sensitivity to the strong scent or the presence of benzene. Benzene is a known carcinogen that can irritate the sinuses, throat, and lungs. However, there is a lack of peer-reviewed scientific evidence directly linking paraffin wax to these health issues.
To minimize potential health risks, it is recommended to use candles made from natural sources such as beeswax, soy wax, or other plant-based waxes. These candles produce less soot and release fewer dangerous chemicals. Additionally, ensuring proper ventilation when burning candles can help reduce the amount of smoke inhaled, minimizing potential health risks.
While paraffin wax candles may pose potential health risks, it is important to note that there is ongoing debate about the extent of their harmful effects. Some argue that candles do not contain enough toxins to be a significant health threat, and that the smoke produced is minimal compared to the daily pollution we breathe from car exhaust and factory emissions.
In conclusion, while the health effects of paraffin wax are not entirely clear, it is advisable to take precautions by opting for natural candles and ensuring proper ventilation when burning any type of candle.

The effects of candle smoke
There is an ongoing debate about whether burning candles is harmful to one's health. Candle smoke contains chemicals that can be dangerous to human health, such as volatile organic compounds (VOCs) and phthalates, which are released from paraffin wax. VOCs are carbon compounds that easily turn into gas at room temperature, and some VOCs like formaldehyde and benzine are potentially carcinogenic. Phthalates have been linked to bladder cancer and endocrine disruption, including reproductive issues and developmental problems.
However, it is important to note that the amount of particulate matter released from burning candles is not enough to cause health issues in humans, according to a 2014 study. Burning candles in a well-ventilated area is unlikely to significantly impact health compared to the daily pollution from car exhaust, factory emissions, and the burning of fossil fuels. Natural candles made from palm stearin, beeswax, or soy wax produce less soot and release fewer dangerous chemicals.
Some studies have examined the potential link between candle use and cardiovascular and respiratory events, but no association was found. However, a cross-sectional study on young university students in Saudi Arabia found a significant association between scented candle usage and wheezing, which may lead to adult-onset asthma. Another study on workers in California reported that 3.8% of work-related asthma cases were linked to exposure to fragranced products.
In conclusion, while candle smoke does contain harmful chemicals, the current research suggests that burning candles in well-ventilated spaces is unlikely to significantly affect one's health. Natural candles made from certain types of wax are recommended to minimize the release of particulate matter and dangerous chemicals.
