Candles are cherished for their ability to create a warm and inviting ambiance, but could they be causing your headaches? Many candles contain synthetic chemicals, such as phthalates, which are used to enhance and prolong their scent. These chemicals can release volatile organic compounds (VOCs) into the air, and inhaling them can lead to headaches and other health issues. In addition, certain fragrances themselves can trigger headaches in some people. Strong floral scents, for example, are more likely to cause headaches than milder, natural scents like citrus or vanilla. If you're prone to allergies or asthma, exposure to candle pollutants can also exacerbate existing symptoms. To reduce the risk of headaches, opt for candles labeled as phthalate-free, non-toxic, or made with essential oils. Beeswax candles are also a safer option as they smell great in their natural state without added fragrances.

What You'll Learn
Scented candles and migraines
Scented candles can be a potential trigger for headaches and migraines. While candles are cherished for their ability to create a warm and inviting ambiance, they can also be a source of indoor air pollution, releasing toxic chemicals and volatile organic compounds (VOCs) into the air.
According to the National Institute of Health and the National Library of Medicine, 34.7% of people will suffer from headaches or migraines when exposed to strong fragrances. This is called osmophobia. In addition to synthetic chemicals, certain fragrances themselves can also be headache triggers for some people. Strong floral scents, for example, are more likely to cause headaches than milder, natural scents like citrus or vanilla. Other scents that have been reported to cause headaches include eucalyptus, cinnamon, and pumpkin.
The type of wax used in the candle can also make a difference. Paraffin wax, derived from petroleum, is a common ingredient in mass-produced candles. When burned, paraffin wax releases harmful toxins and VOCs, including benzene, toluene, and formaldehyde, which can trigger headaches and other adverse health effects, especially in individuals with respiratory sensitivities.
To minimize the risk of headaches and migraines, opt for candles that are labeled as "non-toxic," "phthalate-free," and "paraben-free." Beeswax candles are a safer alternative to paraffin wax as they have a pleasant, delicate scent in their natural state and do not require added fragrances. When browsing scented candles, choose those with milder scents, as overpowering fragrances are more likely to cause headaches.

Synthetic chemicals in candles
Candles are a common household item, often used to create a cosy atmosphere and emit pleasant fragrances. However, some candles contain synthetic chemicals that can have negative impacts on human health. These synthetic chemicals are often found in the wax, fragrances, and wicks of candles.
One of the main synthetic chemicals found in candles is paraffin wax, which is derived from petroleum, a by-product of gasoline production. Burning paraffin wax releases volatile organic compounds (VOCs) such as toluene and benzene, which are known carcinogens. Inhalation of large amounts of soot and VOCs can damage DNA and lead to lung problems. Additionally, paraffin wax candles tend to produce more soot, which can be inhaled and leave behind harmful particles that settle in the home, affecting indoor air quality.
Another synthetic chemical commonly found in candles is phthalates, which are used to extend the longevity of fragrances. Phthalates have been linked to endocrine disruption, reproductive issues, and bladder cancer. It is important to note that companies are not required to disclose specific ingredients in their fragrances, so harmful chemicals may be present without the consumer's knowledge.
Furthermore, some candle wicks, especially in cheaper candles, may contain lead or other heavy metals. When burned, these metals are released into the air, posing serious health risks, particularly for children and pets. Lead exposure has been associated with developmental issues, learning disabilities, and behavioural problems.
To minimise the potential health risks associated with synthetic chemicals in candles, it is recommended to choose candles made from natural materials such as beeswax, soy wax, or coconut wax. These natural waxes burn cleaner and longer, producing less soot and toxic chemicals. Additionally, opting for candles scented with essential oils or other natural sources instead of synthetic fragrances can reduce exposure to allergens and other respiratory irritants.
While the impact of synthetic chemicals in candles may vary among individuals, it is important to be aware of their potential presence and take precautionary measures to ensure the safest and most enjoyable candle-burning experience.

Paraffin wax dangers
Candles are generally considered safe, but certain types of wax and fragrances can cause adverse reactions in some people. Paraffin wax, in particular, has been associated with several potential health risks.
Paraffin wax is a common candle wax derived from petroleum, coal, or shale oil. It is often used due to its low cost and accessibility. However, the process of burning paraffin wax can release toxic chemicals and pollutants into the air, which can be harmful when inhaled. One of the primary concerns with paraffin wax is the presence of toluene, a benzene derivative and known carcinogen. Exposure to toluene can lead to headaches, nausea, dizziness, and insomnia, as it primarily affects the central nervous system in the brain. Additionally, the combustion of paraffin wax releases volatile organic compounds (VOCs) and particulate matter, which can irritate the airways and potentially damage DNA if inhaled in large amounts.
Another concern with paraffin wax is the possible link to cancer. Studies, including one from South Carolina State University, have found that burning paraffin wax emits toxic levels of toluene and benzene. These chemicals are associated with increased rates of certain cancers, particularly acute myeloid leukemia in individuals exposed to high levels of benzene.
Furthermore, paraffin wax can produce black soot, which can accumulate in indoor spaces and contribute to poor air quality. While some argue that the amount of toxic chemicals released by paraffin wax is too small to cause significant harm, it is generally recommended to opt for alternative waxes or fragrance-free candles if you experience any adverse reactions.
To minimize potential health risks, consumers are advised to use soy, vegetable-based, or beeswax candles instead of paraffin wax. These alternatives are considered safer due to their natural state and lower emission of toxic chemicals. However, it is important to ensure that beeswax candles are free from added fragrances, as artificial fragrances are often the trigger for headaches and migraines. When choosing candles, it is essential to prioritize natural and fragrance-free options to ensure a pleasant and safe experience.

Allergy and asthma symptoms
Candles can cause allergy and asthma symptoms. The paraffin wax in candles is a petroleum by-product that releases harmful toxins when burned. These toxins have been linked to various health issues, including headaches, allergies, and asthma. The volatile organic compounds (VOCs) released during combustion can irritate the nasal passages and respiratory system, leading to headaches, congestion, sneezing, and watery eyes.
For individuals prone to allergies, exposure to these airborne pollutants can exacerbate existing symptoms and compromise indoor air quality. The chemicals released from candles are known allergy and asthma triggers. People with these conditions have inflamed airways, making them more sensitive to chemical irritation, which can lead to flare-ups. Fragrance is a common asthma trigger, but paraffin wax might also be a problem.
Additionally, synthetic chemicals like phthalates, commonly used to enhance the scent and prolong the burn time, can release VOCs into the air when the candle is burned. Inhalation of these VOCs can lead to headaches and other health issues. Certain fragrances themselves can also be headache triggers for some people. Strong floral scents, for example, are known to be more likely to cause headaches compared to milder, natural scents like citrus or vanilla.
To minimize the risk of allergy and asthma symptoms, choose candles labeled as ""non-toxic," "phthalate-free," and "paraben-free." Beeswax candles are a safer option as they smell great in their natural state without any added fragrances. Natural alternatives like soy and fragrance-safe options can also help reduce exposure to indoor air pollutants.

Toxic chemicals and health risks
Candles are a source of indoor air pollution, releasing hydrocarbons, particulate matter, and volatile organic compounds (VOCs) into the air when burned. While the impact of these emissions on health is debated, some individuals may be more sensitive to chemical irritation and experience adverse effects such as headaches, especially those with respiratory conditions like asthma or allergies.
A 2009 study found that burning paraffin wax, a common ingredient in mass-produced candles, releases gases and VOCs such as toluene and benzene, which are known carcinogens. These chemicals can irritate the eyes, nose, throat, and skin, leading to headaches, dizziness, and other symptoms. However, some organizations have questioned the reliability of the data in this study.
Another study suggested a possible link between burning candles in poorly ventilated areas and bladder cancer, implicating chemicals called phthalates. Phthalates are synthetic chemicals commonly added to candles to enhance their scent and prolong their burn time. They can release VOCs, which can trigger headaches and other health issues, especially for individuals with respiratory sensitivities.
In addition to synthetic chemicals, certain fragrances themselves can also be headache triggers for some people. Strong floral scents, for example, are more likely to cause headaches than milder, natural scents like citrus or vanilla. Artificial fragrances, rather than the type of wax, are typically the culprit in triggering headaches and migraines.
To minimize the risk of exposure to toxic chemicals and fragrance-related headaches, opt for candles labeled as "non-toxic," "phthalate-free," "paraben-free," or "made with essential oils." Beeswax candles are a natural and safer alternative to paraffin wax, as they have a pleasant, delicate scent in their original state without added fragrances.
