Couple Rushed to Hospital Midnight Due to Mosquito Repellent Smoke

A married couple was nearly in critical condition after being rushed to the hospital at midnight due to mosquito repellent smoke. Medical experts warn about the correct and appropriate use of mosquito repellents, noting that many households are making dangerous mistakes. Mosquito coils work by slow burning to release insect-repelling chemicals, but incomplete combustion can produce carbon monoxide and fine particulate matter in the air. Environmental research indicates that burning just one coil in a 15-square-meter room can dramatically increase PM2.5 levels far beyond safety standards, equivalent to severe pollution. The primary component of many mosquito repellents is pyrethroid, a synthetic insecticide mimicking chrysanthemum extracts. While considered low-toxicity in appropriate amounts, it can cause dizziness, nausea, or respiratory irritation in chemically sensitive individuals. Children, pregnant women, and those with respiratory conditions should be especially cautious. Common misconceptions include believing that more coils mean better mosquito protection, when in fact, excessive use increases chemical accumulation and health risks. Experts recommend using repellents in moderation, ensuring proper ventilation, and considering alternative protection methods like nets, electric mosquito swatters, or natural essential oils.
