Candles have been a source of light and fascination for hundreds of years. They have the power to transform spaces and elevate moods, bringing a sense of romance, passion, mystery, and calm. Beyond their aesthetic appeal, candles are a subject of scientific inquiry, with their flames and waxes offering insights into chemistry and physics. Candle sales are also big business, with companies selling candles made from paraffin wax, beeswax, soy wax, and palm wax, in a variety of fragrances. However, there are concerns about the potential health risks of burning certain types of candles, particularly in relation to the release of particulate matter and volatile organic compounds (VOCs).

What You'll Learn
Candles and their impact on our health
Candles have been a source of light and decoration for centuries, but what impact do they have on our health? This question has sparked some debate, with concerns about the release of potentially harmful toxins and indoor air pollution. However, the available scientific evidence suggests that candles are generally safe for human health, provided certain precautions are taken.
Firstly, it is important to understand that burning candles does release chemicals. All waxes are composed of hydrocarbons, which, when burned, break down into hydrogen and carbon atoms. This process results in the formation of water vapour and carbon dioxide, and, to a lesser extent, soot. While some studies have shown that candles release toxic chemicals like toluene and benzene, which are known carcinogens, the amount released is not considered enough to cause health problems in humans. Additionally, natural candles made from palm stearin or soy wax produce less soot and toxic chemicals than those made from paraffin wax.
The impact of scented candles on health has also been a topic of discussion. While some people claim that scented candles can trigger headaches, migraines, and asthma attacks, there is no scientific evidence to suggest that scented candles are inherently more dangerous than unscented ones. However, it is worth noting that scented candles can cause allergic reactions in some individuals, and it is always advisable to stop using them if you suspect an allergy.
Proper ventilation is crucial when burning candles. While candle smoke in a well-ventilated area is unlikely to significantly affect your health, burning candles in poorly ventilated spaces can contribute to indoor air pollution. Keeping candles away from drafts and ensuring proper airflow can help minimize the amount of smoke and particulate matter you breathe in.
Lastly, fire safety is an important consideration when using candles. Unattended candles are a common cause of household fires, so it is essential to blow them out before leaving the room or falling asleep. Following fire safety guidelines can help ensure a safe and enjoyable experience with candles.
In conclusion, while candles do release chemicals and contribute to indoor air pollution, the current scientific consensus suggests that their impact on human health is minimal when used properly. Ventilation, choosing natural or high-quality candles, and adhering to fire safety precautions are key to enjoying candles without compromising your health.

The history of candles
Candle-making was developed independently in several countries around the world, with various materials being used to create them. In China, textual evidence suggests that candles may have been made from whale fat during the Qin Dynasty (221-206 BCE), while beeswax candles were common in the Tang and Sung Dynasties. In Japan, candle wax was made using wax extracted from tree nuts, while Indian candles were made by boiling the fruit of the cinnamon tree. In Alaska and Canada, tribes used the oily eulachon fish as a candle, as when dried, it would burn when lit at one end.
During the Middle Ages, beeswax candles were introduced in Europe, offering a purer, cleaner-burning alternative to animal-based tallow. However, beeswax candles were expensive and typically only found in churches and wealthy homes. In the 18th and 19th centuries, the growth of the whaling industry led to the use of spermaceti, a wax derived from sperm whales, which burned brighter and had a harder texture than tallow or beeswax.
The 19th century brought significant advancements to candlemaking. In the 1820s, French chemist Michel Eugene Chevreul discovered how to extract stearic acid from animal fatty acids, leading to the development of stearin wax, which burned cleanly and had a hard, durable texture. The same century also saw the introduction of large-scale industrial manufacturing techniques, allowing for the mass production of candles.
Candles enjoyed renewed popularity in the first half of the 20th century due to the increased availability of byproducts from the US oil and meatpacking industries, which provided the basic ingredients for candle-making. In the 1980s, consumer interest in candles as decorative items, mood-setters, and gifts began to surge, leading to the development of new types of candle waxes and scented candles. Today, candles continue to be a multi-billion-dollar industry, with new innovations in scent, wax composition, and manufacturing techniques.

The science behind candles
A candle's wax is composed of hydrocarbons, which are molecules made up of hydrogen and carbon atoms. When a candle is lit, the heat of the flame melts the wax near the wick, and this liquid wax is drawn up the wick by capillary action. The heat then vaporizes the liquid wax, breaking it down into hydrogen and carbon molecules. These vaporized molecules react with oxygen from the air, creating heat, light, water vapour, and carbon dioxide. The blue area at the base of the flame is oxygen-rich, and this is where the hydrocarbon molecules break apart. Above this is a small dark orange-brown section, where carbon continues to break down and form carbon particles, and above this is the large yellow region associated with candle flames.
The flame of a candle creates a convection current, where the heated air rises, and cooler air and oxygen rush in at the bottom to replace it. This cycle gives the flame its teardrop shape. Scientists have also studied candle flames in microgravity environments, finding that without the pull of gravity, the flame takes on a spherical shape.
While candles are a source of light and decoration, there are potential health concerns associated with their use. Burning candles can release particulate matter and volatile organic compounds (VOCs) such as formaldehyde, which may increase the risk of cancer. However, the amount released is generally not considered enough to cause health problems, and proper ventilation can further minimize any potential risks.

Candles as mood-setters
Candles have been a source of light and decoration for centuries. They are now commonly used to set the mood and create a calming ambiance in a room. The warm, flickering light of a candle can instantly transform a space, creating a sense of romance, passion, mystery, hope, and calm. Scented candles, in particular, are known to reduce stress and evoke emotions by stimulating the part of the brain associated with memories and feelings.
The soft, golden glow of candlelight can create a feeling of warmth and tranquility, making it the perfect addition to a relaxing evening at home. Many people enjoy lighting candles during mealtimes, especially in the evening, to encourage a calm and peaceful atmosphere. The gentle flicker of candlelight can also enhance the ambiance of a romantic dinner or a relaxing bath, providing a sense of luxury and serenity.
The use of scented candles can further enhance the mood-setting qualities of candles. Aromatic candles made with essential oils or natural fragrances can fill a room with inviting and luxurious scents, creating a sensory experience that delights the olfactory senses. From floral and citrus notes to warm, earthy aromas, the variety of fragrances available allows individuals to select scents that align with their preferences and desired moods.
In addition to their mood-enhancing properties, candles made from natural sources, such as beeswax, soy wax, or plant-based waxes, are considered better for minimizing the release of particulate matter and potentially harmful chemicals. When used in well-ventilated spaces, candles are unlikely to pose significant health risks, allowing individuals to enjoy the ambiance and scent of candles without concern.
Whether it's creating a romantic atmosphere, enhancing relaxation, or simply adding a touch of luxury to everyday moments, candles have the power to transform not only the appearance of a space but also the mood and feelings of those within it.
