Doctors Warn Improper Aromatherapy Use May Harm Health as Indoor Air Pollution Raises Lung Cancer Risk
On.cc · 1 SOURCESabout 3 hours ago6 MIN
Summary
A recent US study has revealed that aromatic products such as wax cubes and candles release substantial amounts of ultrafine particles during volatilization, causing indoor air pollution levels comparable to car exhaust emissions. Respiratory specialists caution that improper use of aromatherapy products may lead to chronic health effects similar to prolonged exposure to polluted air. The research has particular relevance for Hong Kong and Asian populations, where a disproportionately high number of lung adenocarcinoma cases occur among non-smokers.
Key Points
- US research findings indicate that aromatic wax cubes and candles release large quantities of suspended particles during use, with indoor air pollution levels comparable to vehicle exhaust
- Respiratory specialist Dr. Cho Chung-ho (曹忠豪) explains that ultrafine particles and volatile organic compounds (VOCs) can penetrate the nasal membrane and enter the bloodstream, potentially reaching the brain, blood vessels, and organs including the kidneys
- When VOCs accumulate in poorly ventilated rooms, concentrations increase significantly, raising the risk of particle inhalation and potential kidney inflammation, coughing, asthma attacks, or exacerbation of chronic obstructive pulmonary disease and pulmonary fibrosis
- Environmental scientist Leung Ho-man (梁浩文) notes that synthetic fragrances require organic solvents for dissemination, releasing VOCs even at room temperature, while heating accelerates both the release rate and quantity of pollutants
- Research shows approximately 60% of lung adenocarcinoma patients in Hong Kong and Asia are non-smokers, a phenomenon potentially linked to air pollution increasing gene mutation rates
Why It Matters
The findings have significant public health implications for Hong Kong residents, where indoor air quality is often overlooked despite people spending most of their time indoors. With aromatherapy products becoming increasingly popular for mood enhancement and sleep improvement, proper usage guidelines—including maintaining ventilation, avoiding placement near beds, and limiting exposure duration—can help mitigate potential health risks. The correlation between air pollution and lung cancer among non-smokers underscores the need for greater awareness of invisible indoor pollutants that may be affecting respiratory health in seemingly safe home environments.
