Effects on brain function
A study published in the journal Nature Communications has shown the potential health risks that scented candles can pose. Researchers say incense Candles release pollutants that affect cognitive ability and brain function. Polluants will create inflammation in the brain, reducing the effectiveness of brain function.
The study also assessed the effects of particle materials (PM) from Candles on cognitive ability. Researchers allowed 26 participants to breathe polluted air from burning Candles and clean air for an hour.
Researchers then conducted an experiment and found that participants' attention and emotional perception decreased sharply after inhaling polluted air.
Selective attention helps us focus and eliminate dispersed elements. Social - emotional awareness helps people recognize and understand the emotions of themselves and others.
Researchers explain that indoor pollution creates these cognitive problems. Regular use of candles can cause serious health problems. Therefore, researchers recommend burning Candles in an open place to minimize the risk.
Other health risks
In addition to affecting cognitive function, scented candles can also cause other serious health problems. Christian Pfrang - Professor of atmospheric science at the University of Birmingham, said that scented candles release aldehyde, especially formaldehyde and these substances can be seriously harmful to health.
Aldehyde irritates the skin, eyes, respiratory tract, causing headaches, allergies and dizziness. They are also classified as carcinogens, which can lead to cancer.
When Candles burn, fragrances release volatile organic compounds (VOCs) such as gasoline and polyuricated hydrocarbures (PAH), which can all cause cancer.
According to Professor Christian Pfrang, burning candles also releases PM2.5 particles, which can enter the lungs, along with carbon monoxide (CO), oxygen oxide (NO) and sulfur anhydrates (SO2), all of which contribute to an increased risk of heart disease and asthma.
