Recently, an absurd incident titled ‘An 84-yuan online-purchased smartwatch measured a vacuum cleaner’s blood glucose level as 7.4’ sparked widespread discussion online. The story began when a consumer bought a so-called ‘blood glucose monitoring’ smartwatch for just 84 yuan (about $12) from an e-commerce platform. Out of curiosity, he placed the watch against a running vacuum cleaner—and shockingly, it displayed a ‘blood glucose level of 7.4 mmol/L,’ a value that meets the diagnostic threshold for diabetes. Of course, a vacuum cleaner cannot have blood glucose, revealing the ‘glucose monitoring’ feature as pure false advertising.In reality, the vast majority of low-cost smartwatches on the market today lack genuine non-invasive blood glucose detection capabilities. Medically accurate glucose measurement requires either finger-prick blood tests or certified continuous glucose monitoring (CGM) devices. Ordinary smartwatches use optical sensors only to estimate metrics like heart rate or blood oxygen—not blood glucose. Some sellers exaggerate or even fabricate health features to attract buyers, misleading consumers.Experts warn that users should remain cautious about health-related claims made by inexpensive wearable devices. For reliable glucose monitoring, only approved medical devices should be used under professional guidance. This incident also highlights the urgent need for stricter oversight of health product claims on e-commerce platforms to protect public health decisions from deceptive marketing.
近日，一则‘84元网购手表测出吸尘器血糖7.4’的离奇事件引发网友热议。事件起因是一名消费者在某电商平台以84元购买了一款宣称具备‘血糖监测’功能的智能手表。使用时，他突发奇想将手表贴在正在运行的吸尘器上，结果手表竟显示‘血糖值7.4 mmol/L’——这一数值已达到糖尿病诊断标准。显然，吸尘器不可能有血糖，这暴露了所谓‘血糖监测’功能纯属虚假宣传。实际上，目前市面上绝大多数低价智能手表并不具备真正的无创血糖检测能力。医学上准确测量血糖需通过采血或经认证的连续血糖监测设备（CGM），而普通智能手表仅能通过光学传感器估算心率、血氧等指标，无法可靠检测血糖。部分商家为吸引眼球，在产品描述中夸大甚至虚构功能，误导消费者。专家提醒，对于涉及健康监测的电子产品，消费者应保持理性，切勿轻信低价产品的‘神奇功能’。若需监测血糖，务必使用正规医疗器械，并咨询专业医生。此次事件也再次警示监管部门应加强对电商平台上健康类电子产品的功能宣传审核，防止虚假信息误导公众健康决策。
