Burn Injuries from Heated Humidifiers: A New Risk for Infant Burns

In South Korea, humidifiers are commonly used to regulate indoor humidity, prevent irritation of the eyes and respiratory tract, and reduce respiratory illnesses.Heated humidifiers, which boil water to produce steam, became a preferred alternative after humidifier disinfectant incidents due to their lower risk of bacterial growth.However, careless use has led to burn accidents in children, who may tip over or touch these devices.According to the Korea Consumer Agency's 2023 safety survey, burn incidents from heated humidifiers surged by 141.7% compared to the previous year.The clinical presentation of these burns varies by humidifier design.Rice-cooker-style humidifiers, heating water to 97~100C, often cause multi-site burns with a larger affected area and depths ranging from superficial second-degree to third-degree, particularly when the lid opens after being tipped over.In contrast, covered humidifiers, which heat water in an internal chamber and release steam, typically cause localized superficial second-degree burns to the hand or fingers.By reporting clinical cases treated at our institution, we aim to highlight the risks of heated humidifiers and advocate for enhanced caregiver education on safe device use and placement.We also call for policy-driven safety campaigns to promote cool mist humidifiers and prevent pediatric burn injuries, reducing associated morbidity.(
