Core Viewpoint - The article highlights the risks associated with using heating products like hot water bags and warmers during winter, particularly the occurrence of low-temperature burns, which can lead to severe skin damage [1][11]. Group 1: Incidents of Burns - A 70-year-old woman in Hangzhou developed low-temperature burns resembling "python patterns" after prolonged use of a hot water bag for warmth [2]. - In Wuxi, a woman suffered significant blisters on her leg after sleeping with a warm pack [4]. Group 2: Understanding Low-Temperature Burns - Low-temperature burns occur from prolonged contact with objects around 45°C, which can lead to chronic burns without immediate pain, similar to the "boiling frog" phenomenon [11]. - Firefighters conducted an experiment demonstrating that a warm pack can raise the temperature of a water bottle to 40.7°C after one hour, simulating the effects of using such products on the body [9]. Group 3: Prevention and First Aid - Proper usage of heating products can prevent low-temperature burns, and a five-step first aid protocol is recommended if burns occur: 1. Rinse the affected area with clean cold water for 15-20 minutes [11]. 2. Carefully remove clothing, avoiding breaking blisters [12]. 3. Soak in cold water if pain is severe [13]. 4. Cover the burn with clean materials without applying pressure [14]. 5. Seek medical attention for serious injuries [15].
