Harmful Chemicals in Scented Candles and Air Fresheners Can Negatively Impact Bronchi

Experts have issued warnings that harmful substances released when burning or using products like scented candles and air fresheners can negatively affect bronchial health. Dr. Kwon pointed out the risks associated with products that involve combustion to produce scent. He explained that products burned like scented candles or incense generate smoke, and various harmful chemicals can be produced during the process of burning organic matter.

He cautioned that volatile organic compounds (VOCs) found in diffusers and air fresheners can irritate the nose and bronchi, potentially causing inflammation. Certain ingredients, such as phthalates, may be linked to asthma or bronchitis. Limonene can react with other chemicals to trigger allergic reactions, and when it combines with ozone in the air, harmful substances like formaldehyde can be produced. Prolonged exposure to these substances has been linked to potential impacts on hormonal and immune systems.

Experts particularly emphasize that periodic ventilation is crucial, as indoor air that is not properly ventilated can become worse than outdoor air. Dr. Kwon added that ventilation is essential for improving indoor air quality, as chemical substances generated from moldy smells or the use of city gas can accumulate indoors.

He advised that ventilation should not be avoided even on days with high fine dust concentration. For effective ventilation, Dr. Kwon suggested 'short and strong ventilation,' involving opening windows simultaneously for 5 minutes, three to four times a day. He explained that this method is more effective for improving indoor air quality than leaving windows open for excessively long periods.
