Candles are a popular way to create a relaxing ambiance and add a pleasant aroma to a room. However, they have been the subject of debate regarding their potential impact on indoor air quality and health. Burning candles, particularly those made of paraffin wax, releases toxins such as toluene and benzene, which are known carcinogens. These emissions can accumulate in enclosed spaces with poor ventilation, potentially aggravating asthma, causing allergy-like symptoms, and impacting overall air quality. On the other hand, higher-quality candles made from natural waxes like soy, beeswax, or coconut oil are considered cleaner-burning and safer choices. They produce fewer pollutants and can even help improve air quality by releasing negative ions that bind with toxins. While the scientific community is divided on the extent of health risks posed by candle emissions, it is generally recommended to choose candles wisely, ensure proper ventilation, and follow safety guidelines to minimize any potential hazards.

The health risks of burning candles
While candles are a great way to relax and unwind, there are some associated health risks that come with burning them.
Firstly, it is important to note that anything with an open flame poses a risk to your health and safety. According to the National Fire Protection Association, an average of 20 home candle fires are reported daily in the United States, resulting in injuries, deaths, and property damage. Even small candles can lead to massive blazes, and fires can cause smoke inhalation and burns, which can be life-threatening or result in lifelong disabilities. Therefore, it is crucial to follow candle safety guidelines, such as keeping candles away from flammable objects and ensuring proper ventilation.
In addition to the risk of fire, burning candles can release potentially harmful toxins and chemicals into the air, including hydrocarbons, volatile organic compounds (VOCs), and particulate matter (soot). While the concentrations of these substances are typically low, they can still have health impacts, especially for individuals with sensitivities. For example, exposure to VOCs like formaldehyde and benzene, which are known carcinogens, can irritate the eyes, nose, throat, and skin, leading to symptoms such as headaches, dizziness, and confusion. Additionally, scented candles can trigger or exacerbate asthma and allergy symptoms, causing shortness of breath, eye and throat irritation, and headaches in sensitive individuals.
To minimize the potential health risks associated with burning candles, it is recommended to choose candles wisely. Opt for higher-quality natural wax candles, such as those made from beeswax, soy, or coconut oil, as they tend to burn cleaner and safer than paraffin wax candles. Ensure the wicks are made from natural materials like cotton, avoiding lead or metal wicks. Trim the wicks to 1/4 inch before lighting and always burn candles in well-ventilated spaces to minimize smoke inhalation.
While the therapeutic benefits of candles often outweigh the risks, it is important to be mindful of these potential hazards and take the necessary precautions to create a safer and healthier environment when enjoying candles.

The therapeutic benefits of candles
While candles are known to emit hydrocarbons and other toxins, the amount is generally too small to be a concern. The therapeutic benefits of candles far outweigh any health risks they may pose.
Candles can help lower stress and promote relaxation. The scent of a candle stimulates the limbic system, the part of the brain that is home to our memory and emotions. Hormones like serotonin and dopamine can be produced to help regulate mood. Thus, our emotional state is influenced by the relationship that exists between scents, memories, and emotions. For instance, ylang-ylang promotes feelings of joy and ease, while jasmine improves positive feelings and energy levels. Rosemary, lemon, chamomile, and geranium are good for calming anxiety. Citrus scents are proven to lift your spirits and boost your energy.
The act of candle-making can also be therapeutic. It can be compared to other forms of hands-on art therapy, which are known to help manage stress, anxiety, and even depression. The process of making a candle encourages you to slow down and enjoy the moment, much like yoga or cooking as a form of meditation. The feeling of accomplishment and control in making your own candle—from selecting scents to pouring the wax—is a form of creative release that naturally lifts your mood.
To ensure the therapeutic benefits of candles, it is important to choose and burn candles wisely. Higher-quality natural wax candles, such as those made of soy, beeswax, or coconut oil, are likely to be cleaner-burning and safer choices than paraffin candles. It is also important to ensure proper ventilation when burning candles.

The best candle alternatives
Candles are a popular choice for creating a warm and cosy ambiance in our homes. However, there are several reasons why one might want to explore alternatives to traditional candles. Some of the reasons include safety concerns, allergies, or personal preferences. Here are some of the best alternatives to candles:
LED Candles
LED candles have gained significant popularity as a safe and energy-efficient alternative to traditional candles. These flameless candles provide a realistic flickering effect, mimicking the comforting glow of real candlelight. They come in various sizes, shapes, and colours, allowing you to choose the perfect match for your decor. Additionally, they eliminate the risk of fire hazards and wax spills, making them ideal for households with children or pets.
Room Sprays
Room sprays are a quick and easy way to add fragrance to your space. They can be used as an alternative to candles or in conjunction with them. Cire Trudon's Room Sprays, for example, offer two spray options: a classic spray for smaller spaces and a conical spray for larger areas. Spritz the scent into the air and let it settle on soft furnishings for a lasting fragrance.
Wax Warmers
Wax warmers, also known as candle warmers, are a flame-free alternative. They work by warming scented wax melts or cubes to release fragrance into the space. With wax warmers, you can control the fragrance level by deciding how much wax to melt.
Diffusers
Aromatic diffusers, reed diffusers, and essential oil diffusers are excellent alternatives to candles. They disperse essential oils or fragrances into the air, creating a natural and subtle scent. Diffusers are a safe and easy way to add fragrance to your home without the fire hazards associated with open flames.
Incense
Incense is a great alternative if you prefer the ritualistic feel of lighting a candle. It can create a similar cosy atmosphere, but it may take some time to find an incense that is not too strong, especially if you are sensitive to smell.
These alternatives offer a range of options to create a soothing and tranquil atmosphere in your home without the use of traditional candles. Whether it's the flickering light or the fragrance you're after, there are plenty of choices to explore and enjoy.

How to burn candles safely
While candles are a great way to relax and unwind, it is important to be mindful of the risks associated with them. Here are some tips to ensure you are burning candles safely:
Choose the Right Candle
Select candles made from natural waxes such as soy, beeswax, or coconut oil, and opt for cotton wicks. Higher-quality natural wax candles tend to burn cleaner and slower, reducing the amount of particulate matter and chemicals emitted. Avoid paraffin wax candles and candles with lead or metal wicks as these emit more pollutants.
Prepare Your Space
Place candles on a heat-resistant, sturdy surface, away from anything flammable, and ensure they are at least three inches apart from one another. Keep candles out of reach of children and pets, and never leave them unattended. Avoid burning candles near drafts, vents, or air currents to prevent rapid or uneven burning.
Burn Responsibly
Trim the wick to 1/4 inch before lighting to ensure even burning and avoid dripping. Do not burn candles for longer than four hours at a time, and allow at least two hours to cool before relighting. Keep hair and loose clothing away from the flame, and never leave a candle unattended. Extinguish the candle if the flame becomes too high or flickers repeatedly.
Prevent Fire Hazards
Always keep an up-to-date fire extinguisher nearby. Do not burn a candle all the way down; discontinue burning when 1/2 inch of wax remains in the container or 2 inches for a pillar candle. Never use a candle as a night light or while you may fall asleep, and avoid using them during a power outage.
Be Mindful of Air Quality
While the impact of candle emissions on health is debated, burning candles does release hydrocarbons, including toluene and benzene, which can be irritants. Ensure proper ventilation when burning candles, and if you have respiratory sensitivities or conditions, consider opting for battery-powered flameless candles.

How to choose the healthiest candles
While candles are a great way to relax and unwind, there are some potential health risks associated with their use. The good news is that by choosing your candles wisely and burning them responsibly, you can still enjoy their benefits while minimising any negative impacts. Here are some tips on how to choose the healthiest candles:
Choose Natural Wax Candles
Opt for candles made from natural waxes such as beeswax, soy wax, or coconut wax. These candles tend to burn cleaner and produce fewer harmful byproducts than those made from paraffin wax. Beeswax candles, in particular, are a great choice as they burn with minimal soot and do not emit chemicals, purifying the air instead of polluting it. They also have a subtle, natural fragrance that comes from the nectar of flowers and honey.
Avoid Synthetic Fragrances
Scented candles often contain synthetic fragrances that can release dangerous volatile organic compounds (VOCs) and other toxins, even at room temperature. These compounds can include phthalates, which disrupt hormones, and asthmagens, which can cause asthma. Instead, look for candles that use natural fragrances or pure essential oils processed without solvents.
Check the Wick Material
Avoid lead or metal wicks as they can release toxic heavy metals into the air. Choose candles with wicks made from cotton or wood. If you're unsure if a wick contains lead, rub a sheet of white paper on the wick of an unused candle. If there is a grey mark on the paper, the wick contains lead.
Ventilate Your Space
Regardless of the type of candle you choose, always ensure proper ventilation when burning candles to maintain good indoor air quality. This will help reduce the concentration of any emissions released by the candle.
Burn Responsibly
Follow candle safety guidelines and never leave a burning candle unattended. Keep candles away from flammable objects, furniture, draperies, and out of reach of children and pets. If a candle is emitting a noticeable carbon cloud, do not use it indoors.
By following these tips and choosing candles made from natural waxes, free from synthetic fragrances, and with safe wick materials, you can enjoy a healthier and more sustainable candle experience.
