Candles may dehumidify a room
Candles are a common household item, often used to enhance the ambiance of a room or to enjoy a particular scent. However, beyond these aesthetic qualities, candles may also have a functional benefit: dehumidifying a room.
The idea that candles can dehumidify a space is supported by some scientific evidence and the shared experiences of individuals. For example, in a forum, an individual shared their experience of using candles in a single-wall tent, noting that the candles helped stop the dampness within the tent. Similarly, in a discussion on the impact of candles on room dryness, a person observed that their room felt drier when burning a candle, especially during the evening when the indoor temperature was higher.
The potential dehumidifying effect of candles can be attributed to the nature of combustion. When a candle burns, it releases heat, and hot air can hold more moisture than cold air. As a result, the combustion process may contribute to reducing the moisture content in the surrounding air, leading to a potential decrease in ambient humidity.
However, it is important to note that the impact of candles on humidity levels may be influenced by various factors, including the size and ventilation of the room, the duration of candle burning, and the presence of other heat sources. Additionally, while candles may help reduce moisture, they can also release harmful chemicals, such as benzene, formaldehyde, and soot, which can negatively affect indoor air quality and impact health.
To minimize the negative health effects of burning candles, it is recommended to follow certain precautions. These include trimming candle wicks to ensure an even burn, limiting burning time to one hour at a time, and ensuring proper ventilation in the room. By taking these measures, individuals can enjoy the potential benefits of candles in dehumidifying a space while mitigating any potential health risks associated with indoor air quality.

Burning candles and indoor air quality
Burning candles can have a significant impact on indoor air quality. While they are often used to enhance the ambiance and overall fragrance of a home, they can also negatively affect the air we breathe.
Firstly, it is important to understand that candles can release harmful chemicals into the air. The type of wax used in candles plays a crucial role in determining the level of toxins released. For example, paraffin wax candles can produce carcinogenic toxins such as benzene, formaldehyde, and soot. Soot, a black powdery substance made of impure carbon particles, has been linked to a range of adverse health effects. Therefore, it is recommended to opt for alternative options such as soy or beeswax candles, which burn cleaner than regular paraffin wax candles.
Additionally, proper candle care and usage are essential to minimising their negative impact on indoor air quality. Trimming candle wicks to a length of ¼ inch before lighting helps to reduce flame height and encourages a more even burn. Limiting the burning time of candles to one hour at a time can also reduce the amount of toxin release. Adequate ventilation is crucial when burning candles, as it helps dissipate harmful chemicals. If a candle turns the jar black due to excess soot production, it is best to stop using it and dispose of it properly.
While candles may have a dehumidifying effect, it is important to consider the potential trade-off with indoor air quality. The combustion process of burning candles can produce moisture, which may impact the overall humidity levels in a space. However, proper ventilation can help manage this issue.
In summary, while candles can enhance the ambiance and fragrance of a room, it is important to be mindful of their impact on indoor air quality. By choosing the right types of candles, practising proper candle care, ensuring adequate ventilation, and monitoring combustion by-products, we can minimise the negative effects of burning candles on our health and well-being.

Candle alternatives to reduce moisture
While candles may help reduce moisture, there are other alternatives to consider for dehumidification.
Electric Dehumidifiers
Electric dehumidifiers are a common alternative to candles for reducing moisture. These appliances work by pulling in air from the room, removing the moisture, and then circulating the dry air back into the room. They are typically more effective than candles at reducing humidity and can be used in larger spaces. However, they can be more expensive to purchase and run, and may not be as aesthetically pleasing or relaxing as candles.
Houseplants
Houseplants are a natural way to absorb moisture from the air. Certain plants, such as peace lilies, Boston ferns, and English ivy, are known for their ability to remove moisture from the air. This can help improve indoor air quality and reduce humidity levels. Houseplants also add a decorative touch to your space and can provide other benefits such as improving air quality and reducing stress levels.
Ventilation
Proper ventilation is essential for maintaining healthy humidity levels. Opening windows and doors can help circulate fresh, dry air and remove moist air from your home. This is a simple and cost-effective solution, but it may not be feasible in all weather conditions or locations with high outdoor humidity.
Desiccants
Desiccants are substances that absorb moisture from the air. Products like silica gel packets or moisture absorbers can be placed in damp areas to help reduce humidity levels. They are often used in small, enclosed spaces such as closets or cabinets. Desiccants are a passive form of dehumidification and may not be as effective as active solutions like electric dehumidifiers or proper ventilation.
Lifestyle Changes
Simple lifestyle changes can also help reduce moisture in your home. For example, activities such as cooking and showering can increase humidity levels, so ensuring your kitchen and bathroom are well-ventilated during and after these activities can help manage moisture. Additionally, ensuring your home is properly insulated and sealed can help prevent moisture ingress from the outside.

The health impact of candles
There is much debate about whether candles are good or bad for your health. Burning candles can release chemicals that may be harmful, such as volatile organic compounds (VOCs) and phthalates. These have been linked to an increased risk of bladder cancer and can cause headaches, shortness of breath, and coughing. However, the amount of particulate matter released from burning candles is not enough to cause health problems in humans, according to a 2014 study.
Scented candles, in particular, have been known to cause headaches and migraines for some people. They can also trigger allergies, asthma, or allergic reactions, and it is recommended that if you think you are allergic, you should stop using them and consult a doctor.
It is important to note that the impact of candles on health may be influenced by factors such as the type of wax, fragrance, and ventilation. Paraffin wax, commonly used in candles, releases potentially dangerous chemicals due to its petroleum origin. Natural candles made from beeswax, soy wax, or other plant-based waxes are considered safer options as they produce less soot and toxic chemicals.
Additionally, proper ventilation plays a crucial role in minimizing the potential health risks associated with candle usage. Burning candles in a well-ventilated space is generally considered safe, and it is recommended to open a window while burning a candle.
While there are concerns about the potential health risks of burning candles, the therapeutic benefits of their use, such as stress relief and relaxation, are often weighed against these risks. The mood and scent are closely linked, as fragrance molecules can bind to proteins in the nasal passage and affect emotions, thoughts, and memory.
To minimize any potential health risks, it is advisable to follow candle safety guidelines, choose high-quality candles, and ensure proper ventilation when burning candles.
