Candles are a popular way to create a cosy atmosphere, but are we compromising our health for the sake of a pleasant smell and soft lighting? The short answer is that there is no definitive research proving that candle smoke is harmful to inhale. However, it is important to note that burning candles do release hydrocarbons, volatile organic compounds (VOCs), and phthalates into the air, which can cause headaches, coughing, and shortness of breath. While the concentrations of these compounds are low, certain candles, such as those made with paraffin wax, produce more soot and potentially dangerous chemicals. Natural candles, such as those made with beeswax or soy wax, are recommended for minimizing the amount of particulate matter inhaled.

What You'll Learn
The dangers of candle smoke are debated
There is some debate about whether inhaling candle smoke is harmful to one's health. Candle smoke contains particulate matter (soot) and volatile organic compounds (VOCs), which can be released into the air when a candle is burned. These compounds include formaldehyde and benzene, which are known carcinogens. However, it is important to note that the concentrations of these compounds in candle emissions are very low and are unlikely to pose a significant health risk, especially when compared to the pollution we breathe daily from other sources.
Some people argue that candles release potentially harmful toxins, while others claim that the amount of toxins is not enough to cause any health issues. There is currently a lack of definitive research showing that exposure to candle smoke increases the risk of developing health conditions. However, it is worth mentioning that inhaling any type of smoke, including candle smoke, is not advisable and can be unhealthy. Burning candles also increase air pollution, which can be a concern for individuals with respiratory issues or sensitivities to fragrances.
The type of wax used in candles can also impact the amount and toxicity of the smoke released. Paraffin wax, which is commonly used in commercial candles, is a petroleum by-product and may pose health risks when inhaled. Natural candles made from beeswax, soy wax, or plant-based waxes are considered better alternatives as they produce less soot and release fewer chemicals. However, it is important to note that even these natural alternatives cannot guarantee a completely "clean" burn.
To minimize the potential risks associated with candle smoke, it is recommended to burn candles in a well-ventilated area and to follow proper fire safety precautions. Trimming the candle wick before burning can also help reduce the amount of smoke produced. While the dangers of candle smoke may be debated, taking simple precautions can help ensure a safer and more enjoyable experience.
In conclusion, while there may be some valid concerns about the potential health risks of inhaling candle smoke, the lack of conclusive evidence and the relatively low concentrations of harmful compounds suggest that the risks are likely minimal when candles are used responsibly and in well-ventilated spaces.

Candles release hydrocarbons, but the amount is insignificant
There is a lot of discussion around the potential dangers of burning candles. Some sources claim that burning candles release potentially harmful toxins, such as volatile organic compounds (VOCs) and phthalates, into the air. These toxins can include hydrocarbons, toluene, benzene, formaldehyde, and polycyclic aromatic hydrocarbons. While these chemicals are known to be potentially dangerous, the small amount released when burning a candle is generally considered insignificant and only a cause for concern in certain situations.
The debate surrounding candle smoke centres on whether the emissions generated, even if tiny, can meaningfully impact one's health. According to pulmonologist Sobia Farooq, candle burning can contribute to poor indoor air quality, but the available research does not suggest that people should stop lighting candles, especially in well-ventilated spaces.
It is worth noting that the type of candle and the way it is burned can affect the amount and type of emissions produced. For example, scented candles have been found to produce more soot than unscented ones, and paraffin candles produce more soot than soy, beeswax, or coconut wax candles. Additionally, burning a candle for too long can create an abundance of soot. Therefore, it is recommended to follow proper candle etiquette, such as trimming the wick and burning for no more than three to four hours at a time.
While there is some concern that extended exposure to particulate matter and VOCs can lead to heart and lung problems, no definitive research shows that exposure to candle smoke increases the risk of developing any health condition. The smoke from burning candles in a well-ventilated area is unlikely to significantly affect one's health compared to the daily pollution encountered in everyday life.

Natural candles are the healthiest option
There is some debate about whether burning candles is bad for your health. While some people claim that candles release potentially harmful toxins, others argue that candles do not contain enough toxins to pose a significant health threat. However, it is important to note that inhaling any type of smoke can be unhealthy.
Natural candles, made from materials like beeswax, soy wax, or coconut wax offer a healthier and more eco-friendly alternative to traditional candles. These natural waxes burn cleaner and produce fewer harmful byproducts than candles made from paraffin wax. For example, candles made from palm stearin release half as much soot as paraffin candles. Natural candles also have a lower environmental impact, making them a more sustainable choice.
Beeswax candles, in particular, stand out as a top choice for non-toxic options. They burn cleaner, with minimal soot, and have a longer burn time compared to other natural waxes. Beeswax candles also purify the air and give off a subtle, naturally-scented fragrance. Soy wax is another excellent option, as it provides a cleaner burn than paraffin wax and is a renewable resource.
In addition to the type of wax, it is important to consider the wicks used in candles. Many commercial candles use wicks containing metal cores, which can release harmful compounds into the air. Natural candles, on the other hand, use wicks made from natural fibers like cotton or wood, ensuring a safe and clean burn.
Overall, natural candles are the healthiest option when it comes to candle choices. They are free from harmful chemicals and synthetic fragrances, providing a cleaner burn and a delightful aroma without compromising your health. By choosing natural candles, you are not only supporting your health but also the planet's well-being.

Candle smoke contains volatile organic compounds
Candle smoke is a mixture of extremely small liquid droplets and particles that can enter your lungs. Inhaling any type of smoke can be unhealthy. While there is no definitive research showing that exposure to candle smoke increases the risk of developing health conditions, it is important to minimise the amount of smoke you breathe in. Burning candles in a well-ventilated area can help reduce the potential impact on your health.
The emission of VOCs from scented candles has been a particular focus of research. Studies have found that scented candles can release various VOCs, including both pleasant aromas and toxic components, even before they are lit. When lit, formaldehyde emissions can be significantly higher, with concentrations reaching up to 2098 ppb in some cases.
To minimise exposure to VOCs and other harmful compounds, it is recommended to use candles made from natural sources, such as beeswax, soy wax, or other plant-based waxes. These alternatives are known to release fewer toxic chemicals and less soot. Additionally, proper candle care, such as trimming the wick and avoiding drafts, can help reduce smoke production and improve air quality.

Scented candles may trigger asthma and allergies
While candles can lift your mood and bring warmth to your home, it is important to be aware of the potential health risks associated with inhaling candle smoke, especially for people with asthma or allergies.
Scented candles, in particular, can emit harmful substances such as volatile organic compounds (VOCs), benzene, and toluene, which are dangerous pollutants. These chemicals can trigger asthma attacks and even damage the brain, lungs, and central nervous system. The risk of an asthma attack is heightened when scented candles are burned in unventilated areas, as the accumulation of these chemicals in the air can be harmful even for those without asthma or allergies.
Paraffin wax candles, which are the most common type of commercial candle, have been flagged by some as potentially harmful due to their petroleum by-product composition. However, this claim is refuted by many experts, including dermatologist Ranella Hirsch, who asserts that paraffin-wax candles, when used as directed, do not appear to cause harm when inhaled. Nonetheless, it is recommended to opt for candles made from natural sources such as beeswax, soy wax, or other plant-based waxes to minimize the amount of particulate matter and potentially harmful chemicals released into the air.
To further reduce the potential health risks associated with candle smoke, it is advisable to burn candles in a well-ventilated area and to keep them away from drafts, as this can help decrease the amount of smoke produced. Additionally, trimming the wick of the candle before lighting it can also reduce the amount of smoke emitted.
While the smoke from burning candles may not significantly affect your health compared to other forms of pollution you encounter daily, it is important to be mindful of the potential risks, especially for individuals with asthma or allergies. Taking simple precautions, such as choosing natural candles and ensuring proper ventilation, can help minimize any potential negative impacts on your health.
