Health Risks of Mosquito Coils and Natural Mosquito Repellent Methods
Mosquito coils are cherished as a classic symbol of summer.
The swirling smoke and unique scent are staples of a Japanese summer, but many people may wonder what kind of effect they have on the body.
On the other hand, natural mosquito repellent methods are also gaining attention for those who want to avoid chemical ingredients.
Main Ingredients and Effects of Mosquito Coils
The active ingredient in mosquito coils is primarily pyrethroid.
It acts on the nervous system of insects to exert a paralyzing and insecticidal effect.
Health Impacts and Risks to Humans
Although there are few major problems with normal use, the effects of the smoke itself cannot be ignored.
Acute Irritation Symptoms
Fine particles (PM2.5) and volatile organic compounds contained in the smoke can cause irritation to the eyes, throat, and nose, as well as coughing, shortness of breath, headaches, and malaise.
This is particularly noticeable when used for long periods in poorly ventilated, enclosed spaces.
People with respiratory diseases such as asthma, infants, and the elderly tend to be more prone to symptoms.
Effects on the Respiratory System
It has been pointed out that smoke particles can irritate the airways and increase the risk of asthma and wheezing. Some overseas studies have reported a link in children.
Concerns About Carcinogenic Substances
Combustion produces trace amounts of benzene, formaldehyde, and tar.
A 2003 study estimated that burning one coil produces as much PM2.5 as 75 to 137 cigarettes and as much formaldehyde as about 51 cigarettes, a figure that is widely cited.
However, this varies depending on actual exposure levels and conditions, and mosquito coils themselves are not classified as established carcinogens by the International Agency for Research on Cancer.
Nevertheless, there are instances where epidemiological studies in Taiwan have suggested a link to lung cancer.
Natural Mosquito Repellent Methods
If you want to avoid chemical ingredients, natural measures are useful.
While the effects are often weaker and shorter-lasting than chemical repellents, their great appeal lies in their ease of daily use and high safety!
Natural Ingredients Considered Highly Effective
• Lemon Eucalyptus Oil
Derived from plants, it has been reported by the CDC and the National Institute of Infectious Diseases to be as effective as low concentrations of DEET.
The duration of effect is about 2 to 6 hours.
It is not recommended for children under 3 years old.
• Citronella and Lemongrass Essential Oils
Ingredients such as citronellal repel mosquitoes.
• Catnip, thyme, clove, geranium, and lavender also have repellent effects.
Summary
While mosquito coils are an excellent traditional means of pest control, using them in closed rooms or inhaling the smoke for long periods places a significant burden on the throat and respiratory system.
Especially in households with small children or people with asthma, consideration for the usage environment is essential.
On the other hand, natural mosquito repellents using herbs and essential oils are gentle on the skin and body, and their appeal lies in being able to incorporate them while enjoying their scent!
