Soy candles emit less soot and harmful chemicals
Candles can worsen asthma symptoms in some individuals. While not all asthmatics will have issues with candles, certain factors associated with candles can be problematic for those with asthma. Burning candles release particles and chemicals into the air, including soot, particulate matter, and volatile organic compounds (VOCs). These pollutants can have adverse effects on indoor air quality and potentially affect the respiratory health of both humans and pets.
Soy candles are a safer and more environmentally friendly alternative to traditional paraffin wax candles. Soy wax is derived from soybeans, a renewable and biodegradable resource. When burned, soy wax candles produce significantly less soot and harmful chemicals. Paraffin wax, on the other hand, is derived from petroleum and releases pollutants such as toluene and benzene, which are probable carcinogens. Soy wax burns at a lower temperature, resulting in a slower and more even burn, enhancing the longevity of the candle and ensuring a more consistent release of fragrance.
The reduction in indoor air pollutants makes soy wax candles a healthier choice, especially for those with allergies, asthma, or sensitivities to air quality. Additionally, the natural composition of soy wax makes it easier to clean up spills with just soap and water.
For asthmatics, it is advisable to pay attention to individual sensitivities and consult with a healthcare provider for personalized advice. While fragrance oils and strong scents can trigger asthma attacks, soy candles are recommended as a safer alternative due to their cleaner burning properties and reduced emissions of harmful chemicals.
Beeswax and coconut candles are also recommended for asthmatics as they burn very cleanly and are natural alternatives to paraffin wax candles.

Scented candles can trigger asthma attacks
Burning candles release particles and chemicals into the air, including soot, particulate matter, and volatile organic compounds (VOCs) like formaldehyde, which may increase your cancer risk. Even though scented candles release these compounds, it is unclear if they impact your health due to the small amounts present. However, it is possible that exposure to these compounds over many years could have adverse effects.
Some candles can also emit harmful substances such as benzene and toluene, which are dangerous pollutants. These chemicals are not only triggers for asthma attacks but can also damage the brain, lungs, and central nervous system. Additionally, candles can contribute to indoor air pollution, with emissions building up on walls and staining paint, as well as affecting upholstery fabrics and carpets.
It is important to note that asthma triggers can vary from person to person. Individuals with asthma should pay attention to their own sensitivities and consult with a healthcare provider for personalized advice on managing their condition. While soy candles are generally considered a healthier choice due to their reduced emissions, it is the scent, rather than the wax, that is the main issue for asthmatics.

Burning candles release pollutants that affect respiratory health
Burning candles can release various pollutants, such as soot, particulate matter, and volatile organic compounds (VOCs) like formaldehyde, into the air. These pollutants can have detrimental effects on indoor air quality and, consequently, on the respiratory health of humans and pets.
For instance, a study conducted on university students from Saudi Arabia revealed that 24.8% of those exposed to scented candles experienced adverse respiratory symptoms such as coughing and shortness of breath. Similarly, a study on workers in California found that 3.8% of confirmed work-related asthma cases between 1993 and 2012 were linked to exposure to fragranced products, including scented candles.
The synthetic fragrances used in candles often contain phthalates, which are released into the air as the candles burn. Inhaling or absorbing phthalates through the skin can exacerbate allergic symptoms and asthma, as well as alter hormone levels. Additionally, some candles, particularly those made from paraffin wax, can emit harmful substances such as benzene and toluene, which are not only dangerous pollutants but also potential carcinogens.
To minimize potential risks, individuals with asthma can opt for soy, coconut, or beeswax candles with unbleached cotton, hemp, or wooden wicks. Unscented candles or those scented with pure essential oils are also recommended. Proper ventilation is crucial, and it is advisable to avoid burning candles in poorly ventilated spaces or in excessive quantities.

Soy candles are a natural, biodegradable material
When burned, soy wax candles emit significantly less soot and harmful chemicals, such as toluene and benzene, which are probable carcinogens. This reduction in indoor air pollutants makes soy wax a healthier choice, especially for individuals with allergies, asthma, or sensitivities to air quality. The lower burning temperature of soy wax results in a slower and more even burn, enhancing the longevity of the candle and ensuring a consistent release of fragrance. This makes soy candles more cost-effective and user-friendly, as spills can be easily cleaned with soap and water.
The popularity of soy candles reflects society's growing environmental awareness and the quest for sustainability and health consciousness. As an alternative to paraffin wax, which is derived from petroleum or oil refining residue, soy wax offers a natural and renewable option that burns cleaner and produces less soot, reducing indoor air pollution.
While some individuals with asthma may be concerned about the impact of candles on air quality, it is important to note that the main issues for asthmatics are typically strong scents and fragrances rather than the wax itself. Natural, unscented candles made from soy wax, beeswax, or coconut wax are recommended for asthmatics who enjoy burning candles, as they produce fewer emissions and are free from artificial fragrances and harmful additives.
Overall, soy candles, with their natural, biodegradable, and renewable properties, offer a healthier and more environmentally conscious option for candle lovers, especially those with asthma or allergies, contributing to a pure and non-toxic candle experience.

Asthma triggers vary from person to person
Scented candles, in particular, can trigger asthma attacks in sensitive individuals. The fragrances used in candles often contain phthalates, which are released into the air when the candle burns and can be inhaled or absorbed through the skin. Phthalates can exacerbate allergic symptoms and asthma and alter hormone levels. Studies have shown that fragrance products, including scented candles, are associated with coughing, shortness of breath, migraines, asthma attacks, and allergic rhinitis.
The type of wax used in candles can also make a difference. Paraffin wax candles, derived from petroleum, release harmful chemicals such as toluene and benzene, which are probable carcinogens and dangerous pollutants. These chemicals can build up on walls and fabrics, further affecting air quality. On the other hand, soy wax candles are a more environmentally friendly alternative, emitting significantly less soot and harmful chemicals. Soy wax burns at a lower temperature, resulting in a slower and more consistent release of fragrance, making it a healthier choice for those with asthma or sensitivities to air quality.
However, it is important to note that even soy candles can be problematic for asthmatics if they are scented. The impact of fragrances on asthma seems to be the main issue, with artificial chemical-based fragrances being particularly strong and irritating for some individuals. Therefore, it is recommended to choose unscented candles or those made from natural ingredients, such as essential oils. Other alternatives to consider include flameless LED candles or essential oil diffusers, which can create a pleasant ambiance without the potential risks associated with burning candles.
