Can burning candles at home increase dementia risk?

Research indicates that short-term exposure to particulate matter from candle smoke can negatively affect cognitive functions, which may contribute to an increased risk of dementia.

How does candle smoke affect cognitive function?

Exposure to particulate matter from candle smoke can impair cognitive functions such as emotion recognition and the ability to concentrate on tasks.

What is the primary environmental threat to human health?

Summary

Candle smoke exposure may impair emotion recognition and concentration.
Short-term particulate matter exposure has immediate negative brain effects.
Air pollution poses the primary environmental threat to human health.

Recent research from the University of Birmingham suggests that burning candles at home could be linked to an increased risk of dementia. The study found that short-term exposure to particulate matter (PM) air pollution, including emissions from candles, can negatively affect cognitive functions essential for daily life.

Participants exposed to candle smoke showed immediate impairments in their ability to interpret emotions and maintain concentration. These effects could even manifest during routine activities like grocery shopping, impacting decision-making and focus. While working memory remained unaffected, selective attention and emotion recognition were compromised.

Globally, air pollution is recognized as the primary environmental threat to human health. Established links exist between poor air quality and degenerative brain conditions such as Alzheimer's and Parkinson's diseases. Experts emphasize the urgent need for stricter air quality regulations and public health measures.
