Wearable technology, dominated by smartwatches, has become a multi-billion-dollar industry with a focus on health tracking. These devices monitor various health metrics such as heart rate, sleep patterns, menstrual cycles, and even body temperature. Health Secretary Wes Streeting has proposed distributing wearables to NHS patients in England to enable remote symptom monitoring, such as for cancer treatment reactions. However, the medical community, including GPs like Dr. Helen Salisbury, remains cautious about the reliability and utility of data generated by these devices.
Dr. Salisbury observes a growing number of patients presenting wearable data during consultations but questions its overall usefulness. She warns that while wearables might flag abnormalities, these often result from minor, temporary issues or device malfunctions that don’t require medical attention. Over-reliance on such data could lead to hypochondria, with patients visiting doctors unnecessarily. She stresses that wearables cannot replace medical diagnostics for serious conditions like cancer and advocates for focusing on timeless health advice: regular exercise, moderate alcohol consumption, and maintaining a healthy weight.
Experts also highlight technical limitations. Dr. Yang Wei explains that wearable data can be compromised by movement, battery constraints, and sensor placement, making it less accurate than hospital-grade equipment. Moreover, there are no universal standards for wearable sensors, software, or data formats, complicating their integration into healthcare systems.
Despite these challenges, wearables do encourage healthier habits and may help shift care from hospitals to community settings. However, as Pritesh Mistry from the King’s Fund notes, significant investment in infrastructure, workforce training, and technological standards is needed before wearable data can be reliably incorporated into mainstream healthcare.
