Patna: Mosquito repellent coils and incense sticks, widely used in households to ward off insects, may be causing more harm than protection, a senior physician at Patna Medical College and Hospital (PMCH) has cautioned.
Dr Sanjay Kumar, from the department of medicine at PMCH, said the smoke released by these products contains harmful chemicals that can affect the respiratory system. According to him, frequent exposure may aggravate conditions such as asthma, allergies, persistent coughing and breathing difficulties.
He warned that the risks increase significantly when coils or incense sticks are burned in poorly ventilated or closed spaces. “In such conditions, smoke concentration rises, which can be particularly dangerous for children, elderly people and those with pre-existing respiratory illnesses,” he said.
Kumar also pointed to additional side effects reported in several cases, including eye irritation, headaches and skin allergies linked to prolonged exposure to the fumes.
Medical professionals are urging people to limit the use of such products and consider safer alternatives. These include mosquito nets, maintaining hygiene in and around homes, and preventing water stagnation to reduce mosquito breeding. Where necessary, experts recommend controlled use of electric vaporizers or topical repellent creams instead.
Health experts stress that increased awareness and cautious usage are essential to minimise the potential harm caused by commonly used mosquito repellents and to safeguard public health.
