What You'll Learn

Fire hazards
Leaving a candle burning while you sleep poses a significant fire risk. Candles should not be left unattended, even for a short period, as a fire will spread far quicker than people realise.
Burning candles in a closed room can produce small amounts of carbon monoxide, and while significant carbon monoxide poisoning is rare without prolonged exposure to large flames or multiple candles, it is still a risk.
There are several other reasons why leaving a candle burning overnight is dangerous:
- Unexpected events like a draft from an open window or a pet knocking over the candle can easily lead to disaster.
- The heat from the candle can cause the glass jar to crack or even shatter, especially if the candle is neglected and burns down too low.
- A neglected wick can become excessively large and unstable, increasing the risk of the flame flickering and igniting nearby flammable objects.
- Extended burning in a closed room can deplete oxygen levels, potentially leading to drowsiness or headaches.
- Candles generate significant heat, especially when burning for extended periods. This heat can damage furniture or surrounding objects if the candle is placed too close to flammable materials.
To reduce the risk of fire hazards, ensure proper ventilation by opening windows or doors when burning candles. Keep lit candles away from drafts, vents, and flammable objects. Always keep burning candles at least 12 inches away from curtains, furniture, carpets, and clothing.

Carbon monoxide poisoning
Leaving a candle burning overnight is generally not recommended due to the safety risks involved. While the gentle glow of a candle may create a calming ambiance, it is important to be mindful of the potential dangers associated with unattended candles.
One of the main concerns is the risk of fire. Candles left unattended can easily lead to a disaster if something unexpected happens, such as a draft from an open window or a pet knocking over the candle. The heat generated by a burning candle can also cause the glass jar to crack or shatter, especially if the candle is neglected and burns down too low. Additionally, continuous burning for extended periods can result in carbon buildup on the wick, compromising the fragrance experience and increasing the risk of fire due to an unstable wick.
Another concern is the potential for carbon monoxide poisoning. While significant poisoning from a single candle is rare, burning candles in a closed room with poor ventilation can produce small amounts of carbon monoxide. This toxic gas is formed during incomplete combustion when not all the carbon in the candle wax oxidizes completely, resulting in the release of carbon monoxide instead of carbon dioxide. Prolonged exposure to large flames or multiple candles can lead to oxygen deprivation in vital organs and tissues, causing symptoms such as headaches, dizziness, or nausea. In extreme cases, carbon monoxide poisoning can even be fatal.
To reduce the risk of carbon monoxide poisoning and fire hazards, it is recommended to always properly ventilate the room by opening windows or doors when burning candles. Additionally, maintaining the wick at an optimal length and choosing candles with natural waxes, such as beeswax or soy wax, can promote more complete combustion and reduce the emission of harmful byproducts.
If you wish to keep a candle lit overnight for spiritual or devotional purposes, it is advisable to opt for battery-operated or LED candles, which can provide the same ambiance without the associated risks. Remember, candle safety should always be a priority, and leaving a burning candle unattended can have potentially dangerous consequences.

Fragrance alteration
Leaving a candle burning for too long can alter its fragrance profile. This is because the volatile top notes of the fragrance oil often burn off first, leaving behind the heavier base notes, which can create an unpleasant or overpowering scent.
Burning a candle for more than four hours can lead to a compromised fragrance experience. To avoid this, it is recommended to limit burning time to a maximum of four hours at a time and to prioritise safety by keeping candles away from flammable materials and placing them on heat-resistant surfaces.
If you're looking for a long-lasting fragrance experience, consider using wax melts and a wax warmer. Wax warmers use electrical heat to melt the wax, eliminating the open flame risk. This allows you to enjoy the fragrance of the candle without having to worry about the potential fire hazards, health risks, and candle care associated with leaving a candle burning overnight.
Additionally, always remember to extinguish candles before leaving the room or going to sleep. Never leave a burning candle unattended, even for a short period. By following these safety tips, you can create a safe and enjoyable candle experience without compromising your peace of mind.

Candle care tips
Leaving a candle burning while you sleep is a significant fire hazard and can also produce small amounts of carbon monoxide, so it is not recommended. If you would like to keep a light burning overnight, opt for an electric or battery-powered candle.
- Keep your candle wick trimmed before each burn. This prevents black residue around your candle jar and allows for a more controlled flame.
- Avoid prolonged burning, especially over four hours, as this can lead to an increased risk of fire due to a neglected wick and potential damage to surrounding objects from excessive heat.
- When lighting a candle for the first time, let it burn for a maximum of four hours, allowing the entire upper layer of wax to melt. This ensures the perfume reaches its optimal diffusion potential and will ensure a long and even burn in the future.
- To prevent hot wax from splattering, use a candle snuffer when putting out the candle. Allow the candle to cool before moving it and covering it with a lid to prevent dust from gathering.
- Place your candle on a heat-resistant surface or in a candle holder to avoid burn marks on your furniture.
- Keep your candle away from drafts, windows, or air vents, as these can cause the candle to burn quickly and unevenly.
- Store your candles correctly to keep them fresh for as long as possible. Keep them in a cool, dark place, as temperature and light exposure can cause candle degradation.
- Do not burn all the wax. Once the wax has reached 5mm in the bottom of the glass container, stop burning it to avoid overheating the jar.

- Proper ventilation: If you choose to burn a candle, ensure proper ventilation by opening windows or doors to reduce the risk of carbon monoxide poisoning and to maintain oxygen levels.
- Limit burning time: Limit the burning time of a candle to a maximum of 4 hours at a time. Continuous burning for extended periods can lead to issues such as carbon buildup, tunneling, fragrance alteration, and heat generation.
