Is lighting mosquito coils harmful to the human body?

The peak season for mosquitoes occurs in summer because it is hot and mosquitoes reproduce quickly. Mosquitoes are little enemies that people hate. At present, many families still mainly use mosquito coils to repel mosquitoes, but they don’t know that this will cause harm to the human body. In fact, the active ingredients of most mosquito coils are pyrethroid insecticides, as well as organic fillers, adhesives, dyes and other additives. The smoke from burning mosquito coils contains many substances that are harmful to the human body. Mosquitoes can be killed, but of course it will also cause a little harm to the human body. Let’s learn about the harm of mosquito coils to the human body.

The long-standing mosquito coil is the earliest insecticide used. Similar mosquito repellent sticks made of traditional Chinese medicine appeared as early as the Southern Song Dynasty thousands of years ago. Mosquito coils use high-temperature combustion to slowly release insecticides into the air, and their mosquito repelling effect is greater than their mosquito killing effect.

Experts recommend that mosquito coils are best used outdoors, such as around the home, at doorways, or in areas with good air circulation. The best mosquito repellent effect is to light mosquito coils in the evening or before dark.

Traditional mosquito coils come in two types: stick incense or coil incense. In recent years, liquid or solid electric mosquito coils have appeared. The principle of solid electric mosquito coils is to absorb the insecticide (pyrethrum) into a piece of paper and use hot air to evaporate the insecticide. The general efficacy can last for 6 to 8 hours. The disadvantage is that the drug is effective when it is first used, and there may be an "overdose", but after 4 to 5 hours, the insecticide evaporates completely, the efficacy deteriorates, and the mosquito repellent effect weakens.

Using the capillary principle, liquid electric mosquito coils that continuously heat and release insecticide substances can just make up for the shortcomings of electric mosquito coils. Liquid electric mosquito coils can be used continuously for a long time, about 60 days, and can even be released at a fixed time.

According to a report conducted by the Institute of Health, electric mosquito coils release not only chemicals such as phenylephrine and toluene, but also many unknown and harmful compounds. If used in a closed room, severe allergic reactions may occur, such as sore throat, nasal congestion, headache, etc. Therefore, it is recommended to maintain air circulation when using electric mosquito coils.

Half an hour before going to bed is a good time to use electric mosquito coils. When in use, doors and windows should be closed and people and pets should be kept away.

In the hot summer, many people like to light mosquito coils to repel mosquitoes, but they don’t know that this will cause harm to the human body. In fact, the active ingredients of most mosquito coils are pyrethroid insecticides, as well as organic fillers, adhesives, dyes and other additives. Therefore, the smoke from burning mosquito coils contains many substances that are harmful to the human body and may induce diseases such as asthma.

It is estimated that the amount of particles released by lighting a roll of mosquito coils is roughly the same as the amount of particles released by burning about 100 cigarettes. The ultrafine particles released can enter and remain in the lungs, which may cause asthma in the short term and cancer in the long term. The second is the mosquito coil base material

Incomplete combustion of fuel produces carcinogens and some compounds that irritate the upper respiratory tract, which can poison the human nervous system.

The above is about the harm of lighting mosquito coils to the human body. It is best to use safe and natural methods to repel mosquitoes in summer, such as using mosquito nets or screens to isolate mosquitoes; or placing a few opened boxes of cooling oil and wind oil in the bedroom. Of course, if you want to eliminate mosquitoes at the source, it is best to clean up places where mosquitoes can easily breed and reproduce, especially standing water and blocked sinks.
