Lighting a beautiful scented candle to relieve stress and tension after work is something that many people do in our country today. The scent and the light bring a wonderful sense of relief and relaxation. But have we ever thought about whether this candle smoke can have any effect on our health? Some say it is good, while others say it is harmful to the body. Let's talk about this in detail today.
How does smell affect our mind and body?
Have you ever wondered why certain smells bring back old memories? Some smells are incredibly pleasurable, while others give you a headache. There's a scientific reason for all of this.
Simply put, the tiny odor molecules in a scent travel up our nose and directly connect with the part of the brain that controls emotions, thoughts, and memory. This part is called the limbic system. These odor molecules are so small that they can even cross the blood-brain barrier and affect our nervous system. This is why some scents can lower our blood pressure and heart rate , and alter brain function.
How do candles really relax the mind?
Many times we light a candle to relieve stress. The main reason for this is not the candle itself, but the scent it contains. Many candles today contain essential oils . These are natural compounds extracted from plants. Some ancient cultures have used these essential oils for mental, physical, and even spiritual healing.
There are several essential oils that are particularly helpful in promoting calmness, better sleep, and reducing anxiety.
- Lavender
- Jasmine (J AS mine) - In our language, the name is Periya Sambu
- Rose
- Sandalwood
- Chamomile
- Ylang-ylang
The sense of comfort you feel when you light a candle with a scent like this is amazing.
So are candles really harmful to the body?
This is where the problem begins. There is a lot of debate about whether certain chemicals that are released into the air when candles are lit can be harmful to our health. This is especially true of paraffin wax and synthetic fragrances, which are made from petroleum products.
Research has shown that burning candles releases toxic chemicals into the air. However, there is still no clear consensus on whether the amount of those chemicals is enough to harm our health.
| Possible risk | Scientific explanation | But remember... |
|---|---|---|
| Cancer Risk | A 2009 study found that when paraffin wax is burned, it releases gases such as toluene and benzene, which are known carcinogens. | However, some institutions argue that the reliability of the study is questionable because the data has not been made public. |
| Respiratory Issues | Inhaling excessive amounts of particulate matter and VOCs (Volatile Organic Compounds) from burning candles can damage the lungs. | Another study in 2014 found that the amount of chemicals emitted from a candle during normal use is not enough to cause cancer. |
| Bladder Cancer | Another study suggested a possible link between burning candles in poorly ventilated spaces and bladder cancer, raising concerns about chemicals called phthalates . | This is also not yet fully confirmed and further research is needed. |
What happens to people with asthma, allergies, and headaches?
This is something that many people know from experience. If you have asthma or other allergies, the smell of candles can be a bit of a problem. People with these conditions often have slightly swollen and sensitive airways. So when you breathe in a chemical, it can trigger an attack . It's not just the smell that's the problem here, but the fumes from the paraffin wax can also be a factor.
So are headaches. For some people, smell is a major trigger for headaches or migraines . In medicine, we call this condition osmophobia . It means hypersensitivity to smell.
If you have this condition, and you experience symptoms like runny nose, sneezing, chest tightness, or headaches when you light candles, it could be a warning from your body.
How to use candles safely?
Okay, so, with all of this in mind, should we stop using candles altogether? No. In general, candles don't pose any major health risks if used correctly and safely. You can reduce your risk even further by following these simple steps.
1. Ventilate well
The problem is not the amount of chemicals released from the candle, but rather the concentration of them in one place. So, if you light a candle, light it in a well-ventilated room . If possible, leave a window slightly open. But don't place the candle in a place where it is directly exposed to the wind.
2. Choose natural waxes
Paraffin wax is the one that releases the most chemicals. So, choose candles made with beeswax, soy wax , or coconut oil instead. Check the label to make sure it's made with 100% natural wax or mixed with paraffin.
3. Be careful about the smell
If you are someone who gets headaches or allergies from scents, it is best to use unscented candles. If you want a scent, choose candles made with natural essential oils instead of artificial fragrance oils.
4. Don't forget to put out the fire! (Fire hazards!)
This is the most important thing. More than just health issues, candles are a common cause of house fires. Never leave a lit candle unattended . Be sure to extinguish the candle before going to bed or leaving the room.
