Candles have been a source of light and decoration for centuries, but are they harmful to our health? There is a lot of debate surrounding the safety of candles, with some claiming that they release harmful toxins and others arguing that the amount of toxins is not enough to pose a health threat. The truth lies in the type of candle, the length of exposure, and the ventilation of the space. While candles do release particulate matter and volatile organic compounds (VOCs) such as formaldehyde and benzene, the amount released is typically not enough to cause significant harm. However, extended exposure to particulate matter can lead to heart and lung problems, and certain VOCs are potentially carcinogenic. As such, it is important to take precautions when burning candles, such as ensuring good ventilation, avoiding lower-quality candles, and being mindful of any respiratory conditions.

Candles made from paraffin wax are said to be harmful as they release volatile organic compounds (VOCs) when burnt
There is some debate about whether burning candles is harmful to health. Candles made from paraffin wax, a cheap byproduct of petroleum, are of particular concern. Paraffin is the most widely used candle wax globally, and it releases volatile organic compounds (VOCs) when burnt.
VOCs are carbon compounds that easily turn into gas at room temperature. Some VOCs, like formaldehyde and benzine, are potentially carcinogenic. They are regularly found in car exhaust, factory pollution, and anything that burns fossil fuels. While candles do release VOCs, the amount is not considered enough to cause health problems in humans. However, minimizing smoke inhalation is always recommended, and burning candles in a well-ventilated area is advised.
The European Candle Association suggests the following practices to minimize smoke: avoid burning candles in drafty areas, keep wicks trimmed to 5-10mm, use a candle snuffer or dip the wick in wax instead of blowing it out, and ventilate the room after extinguishing.
Natural candles, such as those made from palm stearin, beeswax, soy wax, or plant-based waxes, are said to release fewer toxic chemicals and less soot than paraffin wax candles. These natural alternatives are recommended for those concerned about the potential negative health effects of burning paraffin wax candles.
It is worth noting that scented candles, regardless of their wax type, may also be of concern. The artificial fragrances and colorants used can contribute to various scents and potentially harmful compounds when burned. Therefore, opting for candles with essential oils or those labeled as phthalate-free is recommended.

Candles made from natural sources such as beeswax, soy wax, or palm wax are considered safer alternatives
Candles made from natural sources, such as beeswax, soy wax, or palm wax, are considered safer alternatives to paraffin candles. Paraffin wax is a by-product of petroleum refining, and as such, it is a highly toxic and environmentally unfriendly product. Conversely, beeswax candles are said to improve the quality of the air in a room when burned. Beeswax releases negative ions as it burns, which attract the positively charged airborne pollen, dust, mites, dirt, and pollutants, pulling them out of the air and reducing indoor pollutants. This can effectively reduce asthma, allergies, and hay fever symptoms.
However, it is important to note that beeswax candles may not be completely safe. The negative ionization of air contaminants may be sucked back into the burning candle or fall to the ground, but this does not eliminate the risk of inhaling these contaminants. Additionally, some beeswax candles may be mislabelled as "pure" and contain a combination of beeswax and toxic paraffin.
Soy wax is also considered a safer alternative to paraffin wax. However, it is important to note that soy is not a natural wax. It is a hydrogenated oil processed with heavy metals, and 96% of soybeans are genetically modified and farmed with pesticides. Soy farming also contributes to deforestation and environmental harm. Nevertheless, soy candles produce less of certain compounds than paraffin candles, although they produce more of other compounds.
Palm wax is another alternative to paraffin wax. Candles made from palm stearin release half as much soot as candles made from paraffin. However, it is worth noting that palm oil is often added to soy wax to stabilize the wax in warm weather, so the environmental harm caused by soy farming may also be associated with palm wax.
Overall, while candles made from natural sources such as beeswax, soy wax, or palm wax are considered safer alternatives to paraffin candles, it is important to consider the potential drawbacks and risks associated with each type of wax.

Burning scented candles can release harmful chemicals and particulate matter into the air, which can be unsafe to inhale at high doses
There is some debate about whether burning candles is harmful to your health. Candles are made from different types of wax, including paraffin wax, beeswax, soy wax, and palm wax. The primary concern with paraffin wax candles is the release of potentially harmful toxins when burned. Paraffin wax is derived from petroleum, and burning it releases volatile organic compounds (VOCs) into the air. These include gases such as toluene and benzene, which are known to be carcinogenic.
However, it's important to note that the amount of particulate matter and VOCs released from burning candles is relatively low and may not pose a significant health risk. According to a 2014 study, the amount of particulate matter released from candles is not enough to cause health problems in humans. Nonetheless, extended exposure to particulate matter from any source can potentially lead to heart and lung problems over time.
The quality of the candle also plays a role in the amount of emissions released. Lower-quality candles tend to emit more particulate matter and chemicals, while higher-quality candles burn more slowly and produce fewer emissions. Natural candles, such as those made from palm stearin, also release fewer dangerous chemicals and less soot than paraffin wax candles.
To minimize the potential risks associated with burning scented candles, it is recommended to follow certain guidelines. Firstly, burn candles in a well-ventilated area to reduce indoor air pollution from soot, VOCs, and smoke. Keep the room spacious and avoid burning candles in small, enclosed spaces like bathrooms. Additionally, look for candles made with essential oils or those labeled as phthalate-free, and avoid dyed candles. Keeping the wicks trimmed to a length of approximately 1/4 inch can also help reduce smoke and emissions.
While the therapeutic benefits of scented candles may outweigh the potential risks for many individuals, it is important to be mindful of certain precautions, especially for vulnerable individuals. For example, it is recommended to avoid burning candles around children, pregnant individuals, or people with respiratory conditions.
