Can You Sleep With a Mosquito Coil?

During the early 1900s, Japanese entrepreneurs developed mosquito coils, which were made from pyrethrum paste. Today, they are widely used around the world. In fact, they are estimated to be used by up to two billion people every year.

However, burning mosquito coils indoors can have negative health effects. They release chemicals that may irritate the respiratory system of adults and kids. They are particularly harmful for babies.

A 2003 study measured the amount of particulate matter (PM) 2.5 that was released by commercially available mosquito coils. The results showed that the average amount of PM2.5 emitted by burning one coil was equivalent to 75-137 cigarettes. The smoke also contained metal fumes.

Researchers found that one of the chemicals used in coils was a carcinogen. Known as methylglyoxal, it was found to have relatively high concentrations in the air. It was also noted to have strong irritation and carcinogenic effects.

Another concern is the emissions of particulate matter. The smoke from mosquito coils has been linked to lung cancer. Similarly, studies have shown that long-term exposure to coils can cause asthma and chronic obstructive pulmonary disease.

Some imported mosquito coils contain S-2, a chemical known to be a carcinogen. S-2 is banned in some countries, including the United States. It has also been banned in India. It produces an extremely potent lung carcinogen as a byproduct.

Compared to conventional coils, charcoal-based coils presented lower emission rates. These were accompanied by a larger number of ultrafine particles.
