Core Viewpoint - The recent drop in temperatures across the country has increased the risk of cardiovascular diseases and respiratory infections, prompting JD Internet Hospital to enhance its online medical services for public health protection during winter [1][2]. Group 1: Health Risks - Sudden temperature drops stimulate the sympathetic nervous system, leading to vasoconstriction, increased blood pressure, and higher blood viscosity, which can trigger severe cardiovascular events such as angina, myocardial infarction, and stroke [1]. - The autumn and winter seasons are already high-risk periods for infectious diseases like influenza and pneumonia, and cold weather exacerbates the risk of virus transmission due to reduced outdoor activities and increased indoor gatherings [1]. Group 2: Service Enhancements - JD Internet Hospital has optimized its service processes to handle the winter patient surge, allowing users to connect with professional doctors via the JD APP for timely consultations, medication guidance, and health management advice [2]. - The "home quick test" service enables doctors to issue test orders online, with nurses or couriers collecting samples at home, providing results within 3 hours for key tests, thus minimizing cross-infection risks [2]. - The remote medical center established in collaboration with Wuhan Union Hospital has served over 10,000 patients across 29 provinces since its launch in May, particularly benefiting communities in areas with relatively weak medical resources [2]. Group 3: Future Plans - JD Internet Hospital plans to expand its expert team and optimize its service system in response to ongoing cold weather, while also promoting health knowledge through educational columns to strengthen public health defenses during winter [2].
