Scented candles are one of the most widely used methods in various places, whether homes, stores, companies, work offices, etc., due to the luxurious scents they provide and their ability to create a comfortable and luxurious atmosphere in the place. But have you ever wondered what the harmful effects of scented candles are on health and what the effect of burning them is on humans?
In this article, let us learn about the secrets behind these elegant candles and their wonderful scents and how they can affect our health, while reviewing how to manufacture candles that are safe for the health of all family members and ideal for daily use.
Are scented candles harmful?
When you light scented candles, the process of burning their constituent materials begins, especially if they are unsafe synthetic materials. This leads to the release of chemicals such as formaldehyde and hydrocarbons. Although these substances may not be dangerous upon short-term exposure, with repeated use for long periods or even in poorly ventilated places, this becomes one of the annoying problems that harm health. So let us learn together about the harms of scented candles to health.
What are the harmful effects of scented candles on health?
Although scented candles seem to be a way to relax, unwind, and improve your mood, they may contain some secrets that negatively affect your health, especially if they are made of unnatural and toxic materials. Therefore, the most prominent harms of scented candles to your health are:
- Respiratory system irritation: The smoke rising from candles contains PM2.5, which are fine particles capable of infiltrating deep into the lungs and causing coughing and shortness of breath.
- Increased asthma symptoms: People who have asthma are more susceptible to being affected by harmful soot, so candles increase the possibility of severe attacks caused by these chemical fumes.
- Allergies: Some people may suffer from an allergic reaction to the artificial fragrances used in candle manufacturing, so this can cause sneezing, headaches, or even blocked sinuses.
- Heart and lung diseases: Fine particles resulting from combustion are similar in effect to car exhaust pollutants, and thus increase the risk of heart disease and strokes.
- Accidental burns: When burning wax comes into contact with the skin or eyes, it may cause serious injuries, especially in children.
- Poisoning: If children inhale large amounts of candle fumes, they may suffer from symptoms of poisoning.
What are the toxic substances in candles?
After we learned about the most prominent harms of scented candles to health, we must know what components cause these harms to avoid their use during candle manufacturing:
Paraffin wax:
One of the most common types of candles, it is made from petroleum derivatives, so when it burns it releases volatile organic compounds (VOCs) such as benzene and formaldehyde, which are linked to an increased risk of cancer and other chronic diseases.
Synthetic fragrances:
Many types of scented candles contain phthalates, which are compounds that have been linked to hormonal disorders and may cause chronic allergies in some people.
Soot:
Or black smoke, which results from the incomplete combustion of candles and can remain suspended in the air for hours, so when this soot is inhaled, it leads to its accumulation in the lungs and thus respiratory problems increase in the long term.
Heavy metals in wicks:
In the past, some types of candles contained wicks reinforced with lead to enhance their strength, and this resulted in serious cases of poisoning, especially for children. Therefore, in our time, cheap candles of unknown origin may not always be safe.
Fine particulate matter “PM2.5”:
They are ultrafine particles and penetrate deep into the lungs, so they may increase the risk of heart and lung diseases.
Volatile organic compounds “VOCs”:
In addition to benzene and formaldehyde, it may contain some other substances that are harmful, so these compounds are classified as carcinogenic substances when exposed to them for long periods.
Safe tips for using scented candles
In order to avoid the harmful effects of scented candles on health, some important points must be followed to reduce the occurrence of these harms:
- Natural candles should be chosen, such as beeswax, coconut wax, palm wax, or soy wax, among others.
- Make sure to trim the wick frequently to maintain the proper length to reduce soot.
- Scented candles should be used in well-ventilated places, and it is recommended to open the windows after extinguishing the candles to freshen the air.
- You should also avoid lighting candles in bathrooms or narrow and closed places.

How can safe candles be made?
To reduce the chance of scented candles harming your health, you must follow these steps to make completely safe candles:
Prepare the necessary materials
Prepare safe candles suitable for use, such as soy, coconut, or clear gel candles, safe natural essential oils, cotton wicks, and glass or metal molds.
Melting the wax
Now you must place the appropriate amount of wax in a heat-safe metal bowl, place it inside a larger pot containing hot water, and leave it on a low heat until the wax melts completely by stirring gently and continuously to prevent any clumps from occurring.
Wax cooling
After the wax melts completely, remove the bowl from the water and leave it for a few minutes until the temperature drops (about 65 – 70 degrees Celsius). Here you can quickly add essential oils slowly so that they do not evaporate, in order to maintain the concentration and quality of the scent.
Install the filament in the mold
Install the wax in the middle of the mold or glass cup that suits your needs. You can install it using a little melted wax or a special adhesive to attach it to the bottom, and install the upper end on a wooden stick or clip to keep it straight in the middle.
Pour the wax into the mold
Then gently pour the wax mixed with essential oil into the mold so that no air bubbles form, leaving a small space at the top, place it in a flat place and leave it to cool at room temperature until it hardens completely.
Cut the wick
After the wax has completely hardened, cut the wick to a suitable length (not exceeding 0.5 cm) to ensure that the candle burns evenly and prevents excess smoke from escaping.
