The National Health Commission held a press conference on "Seasonal Solar Terms and Health (Minor Cold, Major Cold)" on the 13th. In recent years, wearable devices have gradually emerged, and some bracelets, watches, etc. have daily health management functions such as heart rate, blood oxygen saturation, and sleep monitoring. However, it should be noted that these products are mainly used for monitoring in daily life and cannot be used as a basis for disease diagnosis and treatment, nor can they replace corresponding medical examinations and tests. In this regard, Wu Hang, chief physician of Xuanwu Hospital of Capital Medical University, gave an example at the press conference. Taking the sleep monitoring wristband as an example, it predicts the sleep stage through data such as body movement, blood oxygen saturation, and heart rate. Although it can reflect the general trend of deep sleep, light sleep, and wakefulness, it is affected by various factors such as environmental interference, wearing methods, and sensor accuracy, and cannot achieve the accuracy and dimensions of professional equipment. It is arbitrary to diagnose 'sleep disorders' solely based on its unsatisfactory monitoring values. Therefore, we need to have a correct understanding of the role of smart wearable devices in daily monitoring and health management, and view monitoring data rationally. Firstly, health indicators themselves have physiological fluctuations, and if a certain indicator is not ideal, there is no need for excessive anxiety. Secondly, the vast majority of smart wearable devices have not reached the precision of medical devices and can only evaluate their own health status to a certain extent. Thirdly, when there are frequent and significant changes in health indicators, it may indicate potential diseases, and it is recommended to seek medical attention promptly at a medical institution.
