Candles have been used for thousands of years, dating back to the Ancient Egyptians, Romans, and Celts, who used them in religious rituals and to ward off evil spirits. Despite their long history, leaving a candle burning unattended can be dangerous. While some people may forget to blow out a candle before bed or leaving the room, it is important to remember that candles are a common cause of house fires and fire-related deaths. Burning candles can also produce carbon monoxide, which can lead to mild poisoning if there is insufficient ventilation. To stay safe, it is recommended to keep candles away from flammable objects, ensure proper ventilation, and always blow out candles before sleeping or leaving the room.

Fire hazard: Candles left burning can ignite surrounding objects, causing house fires
Candles are a common cause of house fires, and forgetting to blow them out only increases the risk. When left unattended, candles can easily ignite surrounding objects, leading to a potential fire hazard. This is especially true if the candle is left burning in close proximity to flammable materials, such as paper, fabric, or wood.
To ensure safety, it is recommended to keep candles at least one foot away from anything that can burn. This includes curtains, furniture, books, and other household items. It is also advised to avoid using candles in the bedroom or any areas where people may fall asleep, as the risk of a fire starting and spreading unnoticed is significantly higher.
In addition to maintaining a safe distance, proper ventilation is crucial when burning candles. Burning candles in a closed room can produce small amounts of carbon monoxide, which can lead to mild symptoms such as headaches, dizziness, or nausea. While significant carbon monoxide poisoning is rare, it is important to open windows or doors to ensure proper airflow and reduce the risk of poisoning.
Leaving a candle unattended overnight is particularly dangerous. A candle left burning for an extended period can cause the glass to crack or the wick to become unstable, increasing the risk of the candle falling or the flame spreading out of control. Even if the candle does not cause immediate harm, it can still pose a fire hazard if left unattended for too long.
To prevent fire hazards and potential carbon monoxide exposure, it is crucial to blow out candles before leaving the room or going to bed. Using flameless candles is also an option for those who want to enjoy the ambiance of candles without the associated risks. These candles look and smell like real candles but do not pose the same fire risks.

Carbon monoxide: Burning candles in enclosed spaces can produce carbon monoxide, leading to mild poisoning
Burning candles can be a fire hazard, but they can also cause carbon monoxide poisoning, especially in enclosed spaces.
When you burn a candle, it produces carbon monoxide and carbon dioxide. Carbon monoxide is a colourless, odourless, and tasteless gas, often referred to as a "silent killer". It is challenging to detect, and almost 50,000 people visit the ER each year due to accidental carbon monoxide poisoning.
The risk of carbon monoxide poisoning increases when burning multiple candles simultaneously or consecutively. The excessive carbon monoxide in the air enters your system while you breathe and builds up in your bloodstream, depleting the oxygen in your blood. This can lead to several health issues, including headaches, dizziness, nausea, and confusion. In severe cases, carbon monoxide poisoning can even be fatal.
Burning candles in a poorly ventilated room can deplete the available oxygen, increasing the risk of carbon monoxide poisoning. Therefore, it is essential to ensure proper ventilation when burning candles. Keep windows and doors open to allow for the free flow of air and the dissipation of carbon monoxide.
To prevent carbon monoxide poisoning, choose high-quality candles made from natural waxes, such as soy or beeswax, which tend to burn cleaner and produce fewer by-products. Trim the wick to about a quarter of an inch before lighting to prevent a larger flame and reduce the risk of soot and incomplete combustion.
Additionally, avoid burning candles in enclosed spaces or areas with drafts, as these can disrupt the flame and lead to incomplete combustion. Always ensure that candles are never left unattended and are extinguished properly with a snuffer or a damp finger to prevent excess smoke.

Superstitions: Forgetting to blow out a candle is considered bad luck in many cultures, with various beliefs attached
Forgetting to blow out a candle is considered bad luck in many cultures, with various beliefs attached. Firstly, it is important to note the safety risks associated with leaving a candle burning. Candles are a common cause of house fires, and forgetting to blow one out can pose a serious fire hazard, especially if left unattended or near flammable objects.
Beyond the physical risks, there are numerous superstitions surrounding forgotten candles. In some cultures, it is believed that if a candle burns out on its own, an evil spirit is present and intends to harm those nearby. Another superstition holds that if a single candle burns out in a church, someone in the congregation is doomed to die. These beliefs may stem from ancient practices of using candles to ward off evil spirits or to guide spirits to the afterlife, as seen in ancient Egyptian and Roman traditions.
Candles have long been associated with symbolism and magic. In many cultures, it is considered bad luck if a candle accidentally burns down completely. This belief may have originated from the idea that a dark home could attract intruders or leave one vulnerable to harm. Conversely, some superstitions view forgetting to blow out a candle as a sign of good luck, indicating that one's wish will come true.
The act of blowing out candles on birthday cakes also carries its own set of superstitions. People from various cultures believe that blowing out all the candles in one breath grants the birthday person their wish. However, this tradition is not without its concerns, as studies have shown that blowing out candles significantly increases bacteria on the cake icing.

Bacteria: Blowing out candles on cakes increases bacteria on the icing, as per a 2017 food research study
Blowing out candles on a birthday cake is a tradition that has been practised for many years. However, a 2017 food research study found that this tradition may have some unintended consequences. The study, titled "Bacterial Transfer Associated with Blowing Out Candles on a Birthday Cake", set out to examine the potential spread of bacteria when blowing out candles on a birthday cake.
The study found that blowing out birthday candles resulted in a significant increase in bacteria on the cake's icing. On average, there was a 1400% increase in bacterial contamination when the candles were blown out compared to icing not blown on. This increase in bacteria is due to the transfer of oral bacteria from the person blowing out the candles to the cake's surface. The study also found that the amount of bacteria transferred varied from person to person, with some people transferring very little bacteria and others transferring much more.
The researchers suggested that this finding could have implications for food safety, especially if the person blowing out the candles is sick. However, one of the authors of the study, Professor Paul Dawson, a professor of food safety at Clemson University, noted that it is not a major health concern. He stated that if someone did this 100,000 times, the chance of getting sick would probably be very minimal.
While the study may cause some concern, it is important to remember that bacteria are an inevitable part of life and most of the bacteria in our mouths are not harmful. Additionally, if proper food safety practices are followed, the risk of getting sick from eating birthday cake is very low. However, if you are still concerned, there are a few things you can do to reduce the risk, such as scraping off the top layer of frosting or using a sanitary birthday cake cover and candle system.

Safety: Always extinguish candles before sleeping and keep them away from children and flammable objects
Candles are a common cause of house fires and house fire deaths. A candle is an open flame, which means it can easily ignite anything that can burn. It is advised to always blow out candles when leaving the room or going to sleep, and to avoid using candles in the bedroom or other areas where people may fall asleep. It is also recommended to keep candles at least 1 foot away from anything flammable.
Candles should never be left unattended, especially around children. Keep matches and lighters locked away and out of children's reach.
Burning candles in a closed room can produce small amounts of carbon monoxide, but significant poisoning is rare without prolonged exposure to large flames or multiple candles. Symptoms such as headaches, dizziness, or nausea may indicate mild exposure. To reduce the risk of carbon monoxide poisoning, ensure proper ventilation by opening windows or doors when burning candles.
While it may be tempting to leave a candle burning overnight, it is important to always extinguish candles before sleeping. This will not only prevent potential hazards but also reduce the risk of fire.
In addition to the safety concerns, leaving a candle burning for too long can also impact its performance. It is recommended to only burn a candle for up to 4 hours at a time to avoid excessive wax melting and potential cracking of the container.
