Candles are a potential source of emergency heat for those stranded in a car during freezing temperatures. Burning candles inside a car can help prevent condensation from breathing and increase the internal temperature of the vehicle. However, it is essential to ensure proper ventilation to avoid the risk of carbon monoxide poisoning. Additionally, the type of candle and wax used can impact the effectiveness of heat generation. Candles with softer waxes, such as soy, coconut, or apricot, may melt at lower temperatures, while blending with harder waxes like beeswax can increase their melting point. In hot climates, candles left in a car may soften, lose their shape, or melt completely, depending on the wax type, size, and duration of exposure to high temperatures.

What You'll Learn
Candles can prevent condensation from breathing
Burning candles releases hydrocarbons, chemical compounds consisting of hydrogen and carbon, into the air. Some of the hydrocarbons released by candles include toluene and benzene. Toluene is commonly used in paint thinners and adhesives, and exposure to it without proper ventilation can irritate the eyes, nose, throat, and skin, as well as cause headaches, dizziness, confusion, and anxiety. Benzene, on the other hand, is a gas emitted by forest fires, volcanoes, and burning coal or oil, and is used primarily in industrial and pharmaceutical settings. While the small amount of benzene released by burning a candle is not a significant concern, it is important to note that benzene exposure has been linked to an increased risk of leukemia and other blood cancers.
Despite the release of hydrocarbons, there is little scientific evidence to suggest that burning candles pose a danger to one's health. In fact, candles can be useful in certain situations, such as preventing condensation from breathing in an enclosed space like a car. One user on the Bushcraft USA Forums reported that they conducted an experiment where they burned a candle inside their vehicle and noticed that their breath disappeared several minutes after lighting the candle. This indicates that the candle was able to reduce the condensation formed from their respiration.
Another user on the same forum also acknowledged the benefit of candles in removing condensation from the air, stating that the candle will "take out some of the condensation in the air from your respiration and perspiration". This is especially useful in cold weather when condensation can chill you. However, it is important to note that burning candles in an enclosed space, such as a car, can also lead to a build-up of hazardous gases if there is insufficient ventilation.
To minimize the potential health risks associated with burning candles, it is recommended to choose your candles wisely and burn them responsibly. For example, avoid candles with lead-core wicks as these can produce dangerous emissions and lead to lead poisoning. Instead, opt for candles with paper-core, cotton, or wood wicks. Additionally, ensure that the space where you are burning the candle is well-ventilated to prevent a build-up of harmful gases.
Overall, while candles can be useful in preventing condensation from breathing, it is important to take the necessary precautions to burn them safely and minimize any potential health risks.

Candles can be used as emergency heat sources in stranded cars
It is recommended to keep a basic car heating kit that includes matches, candles, and a fireproof metal container to burn them in. Tea light candles, in particular, are easy to find and can be purchased in bulk at a low cost. Additionally, some metal paper clips can be useful for wick maintenance. It is also suggested to keep the windows slightly open to prevent condensation from building up due to respiration and perspiration.
The effectiveness of candles in heating a car depends on various factors, including the size and insulation of the vehicle, the number of occupants, and the outside temperature. While candles can provide some warmth, it is crucial to be cautious and prepared. Having proper emergency supplies, such as extra clothing, blankets, and a first aid kit, is essential for survival in extreme cold conditions.
It is worth noting that running the car engine to generate heat is not advisable due to the risk of running out of gas and the danger of carbon monoxide poisoning if the exhaust pipe becomes blocked by snow or ice. Therefore, candles can be a valuable alternative heat source in such situations. However, it is important to prioritize proper driver training and having essential survival gear, including items like hand warmer packets, heating pads, and an axe, in addition to candles.
In conclusion, candles can indeed be used as emergency heat sources in stranded cars, but they should be part of a comprehensive approach to survival that includes proper preparation, adequate insulation, and other heat retention measures. Being equipped with the right knowledge, supplies, and tools can make a significant difference in surviving challenging situations.

Candles can melt in hot cars
The size and type of candle also play a role in how quickly it melts. Smaller candles tend to melt faster than larger ones, and pillar or tealight candles may have different melting times. Additionally, the car's interior temperature can be much higher than the outside temperature, accelerating the melting process.
To prevent candles from melting in a hot car, appropriate packaging materials are essential. Wrapping candles in materials that do not absorb heat, such as kitchen plastic wrap, can help reduce the risk of melting. Placing the wrapped candle in a cardboard box provides an extra layer of protection. By following these packaging methods, you can minimise the chances of your candles melting, even on hot days.
It is worth noting that leaving candles in a hot car for an extended period can cause damage beyond melting. The fragrance oil in scented candles may separate from the wax and pool on the surface, creating a fire hazard if lit. Therefore, it is advisable to avoid leaving candles in a car for longer than necessary and to prioritise their safe and cool storage.

Candles can be transported safely in hot cars
Candles can be safely transported in hot cars, but there are a few things to keep in mind. Firstly, it's important to choose the right packaging materials. Wrapping candles in materials that do not absorb heat, such as kitchen plastic wrap, can help reduce the risk of melting. Placing the wrapped candle in a cardboard box provides an extra layer of protection and helps to keep the candle cool. This is especially important during hot summer months when the temperature inside a parked car can reach up to 71°C (160°F).
Different types of wax have varying melting points, with coconut and soy wax typically melting between 49°C (120°F) and 54°C (130°F). Therefore, it is crucial to consider the type of candle being transported and its melting point. Smaller candles tend to melt faster than larger ones, and certain shapes, such as pillar or tealight candles, may impact the melting time. For example, a paraffin wax candle may start to melt within 25 to 30 minutes in a hot car.
Additionally, it is advised to avoid leaving candles in the car for extended periods. While they may remain intact in the short term, prolonged exposure to high temperatures can cause softening, loss of shape, or complete melting. If a candle does melt, there is a possibility of salvaging it, especially if it is a container candle that has remained upright. In such cases, place the candle on a flat surface in a cooler environment to allow it to harden again.
By following these precautions, candles can be safely transported in hot cars without the risk of damage or melting.

Candles can be affected by being left in cold cars
One of the main ways candles are affected by cold temperatures is through melting or softening. The internal temperature of a car can exceed the melting point of certain waxes, such as coconut and soy wax, which have lower melting points than traditional paraffin wax. On hot days, the temperature inside a parked car can reach up to 71°C (160°F), while the melting point of coconut and soy wax is typically between 49°C (120°F) and 54°C (130°F). As a result, candles left in a cold car may soften, lose their shape, or even melt completely.
The type and size of the candle also play a role in how it is affected by cold temperatures. Smaller candles tend to melt faster than larger ones, and certain types, such as pillar or taper candles, are more likely to be ruined if they melt. The packaging material and thickness can also impact the melting point, with some plastics being more heat-resistant than wax paper, for example.
To minimize the risk of candles being affected by cold temperatures in a car, it is recommended to use appropriate packaging materials that do not absorb heat. Plastic wrap designed for cooking and cardboard boxes can help regulate the temperature and prevent melting. Additionally, storing candles in a cool, dry location, away from direct sunlight, and bringing them inside when possible can help maintain their integrity.
While candles can be affected by cold temperatures in a car, it is important to note that they can also be affected by extreme heat. Therefore, it is crucial to follow proper storage and transportation guidelines to ensure the candles remain in pristine condition.
