You might be asking yourself, “Do candles give me headaches?” The response is affirmative. Benzene and substances akin to Benzene that are present in paraffin wax have the potential to impact the central nervous system, leading to headaches. These elements are inhaled when scented candles are ignited, emphasizing the need to be mindful of this fact. If you want to avoid triggering headaches, it’s essential to understand the potential risks associated with scented candles.
Benzene
Benzene is one of the main ingredients in many perfumes, candles, and air fresheners. This chemical is very toxic and should be avoided, especially if you’re sensitive to it. This chemical can also be found in household products, such as shampoo, soap, and lotions. It’s most likely to be found in paraffin wax, which is a petroleum by-product.
If you’re concerned about benzene’s effects on your health, you should read the ingredients list carefully. This way, you’ll know exactly what to avoid. Candles containing lead-cored wicks are prohibited in the U.S., but some imports from Mexico and China may still contain them. It’s also important to choose a brand with a reputable manufacturer to avoid any potential health risks. Benzene is a known carcinogen and can cause an increased risk of leukemia and hemitopoid cancer. It’s also known to cause adverse reproductive effects.
In addition to this chemical, burning candles releases particulate matter and harmful chemicals into the air. They contain ultrafine soot particles that are similar to those found in diesel exhaust. These particles can penetrate deep into the lungs and bloodstream. If you suffer from asthma or allergies, you may want to consider burning unscented candles that are made of natural ingredients.

Toluene
Candles with paraffin wax contain toluene, which can trigger headaches and migraines. This chemical, which enters the body through the air, affects the central nervous system. If it is inhaled in large amounts, it can cause severe symptoms including nausea, vomiting, and headaches.
Candles containing essential oils can also cause headaches, particularly strong-smelling scents. They can also cause respiratory distress in people with asthma or other respiratory problems. However, candles with fragrances can also help to prevent headaches associated with high blood pressure, stress, and anxiety. Certain fragrances, such as lavender and lemon, can help to relax people and lower their blood pressure, preventing headaches.
Inhaled toluene is harmful for the fetus. It crosses the placenta, and if the mother is exposed to toluene during pregnancy, the baby will have a high concentration of the chemical. According to the National Institute of Health, toluene can cause congenital malformations and developmental retardation in the fetus.

Benzene-like compounds
Candles contain chemicals called benzene-like compounds, which can cause a headache. These chemicals can also damage your respiratory system and cause respiratory tract infections. They also affect the quality of your indoor air. Benzene-like compounds can be found in paraffin candles.
The chemicals in candles are released at low concentrations. By comparison, walking down a city street will expose you to higher concentrations of potentially toxic chemicals. Candles emit particles on the order of several parts per billion or million. This makes it impossible to know exactly how many benzene-like compounds you’ll be inhaled.
The benzene-like compounds in candles are most dangerous when they come in contact with your eyes or respiratory tract. They cause a headache, dizziness, and even cancer. The amount of soot produced by candles is not significant, but you should always avoid inhaling it.

Artificially scented candles
Artificially scented candles may cause headaches by irritating the trigeminal nerve. This nerve runs through the head, eyes, and mouth. When you inhale an irritating scent, the body releases histamine. This hormone helps the body fight foreign invaders. The resulting inflammation of blood vessels in the head leads to the typical symptoms of a headache. This painful pain is usually felt on one side of the head. The idea of scented candles causing headaches was first put forth by American neurologist Dr. David Geller, who noticed that scented candles were causing migraines.
Artificially scented candles contain a compound called paraffin, which releases chemicals that trigger headaches and migraines. This compound is especially dangerous when used in low-quality candles, which are typically made in China.
