More than half of Brits now own some form of wearable technology, but a significant number admit they do not understand the data their devices produce, and many have ignored health alerts entirely, according to a new study.
The research, commissioned by Cromwell Hospital and conducted by OnePoll, surveyed 2,000 adults. It found that 57% now wear a device that monitors metrics such as heart rate, steps, sleep and blood pressure. Nearly half (46%) actively track their health and wellbeing via a watch, phone or smart ring.
Lack of Understanding Leads to Ignored Alerts
Of those who track their health, 23% admit they do not understand what most of the information is telling them. More than half (60%) have previously looked at data on their device without knowing what it means. Meanwhile, 24% have completely ignored health alerts from their device. The most frequently overlooked warnings relate to heart rate (40%), activity levels (35%) and stress (32%).
When faced with confusing readings, 61% turn to the internet for answers, while 30% simply disregard the data. One in four (26%) said that a lack of understanding left them anxious without good reason.
Expert Warns of Serious Health Risks
Dr Neil Srinivasan, consultant cardiologist at Cromwell Hospital, said: "Wearable technology has changed the way people monitor their health. From steps to sleep and heart rate, we now have a wealth of data at our fingertips, people need to know what they are looking out for.
"Worryingly, this lack of understanding is causing some to ignore alerts and signals which could indicate a serious health issue, particularly ones that are linked to our hearts. These alerts should not be ignored and should be checked out by a healthcare professional, who will be able to tell you what it means and if more investigations need to happen."
Dr Srinivasan added: "We know that early diagnosis can be lifesaving. Using all the tools at our disposal, including wearable technology and preventative screenings, is key to maintaining good health particularly for your heart."
Most Commonly Tracked Metrics and Data Interpretation
The study revealed that steps taken (67%), heart rate (52%) and calories burned (46%) are the most frequently monitored health metrics via wearable technology. However, only 17% can interpret data linked to irregular heart rhythms, and just 21% feel confident understanding information relating to their respiratory rate.
Of those who monitor their health via wearable tech, 28% have sought medical advice following an alert. Among those who did get checked out, 58% found it turned out to be a minor issue, yet 21% said it proved to be an indicator of a more serious health concern. More than a third (35%) have shared data from their device when consulting a medical professional, with 26% believing it resulted in a quicker or more straightforward diagnosis.
New Genomics Prevention Pathway Launches
From 1 September 2026, Bupa will launch a new first-to-market genomics prevention-focused pathway for cardiovascular disease. It will use DNA insights to pinpoint individuals at heightened risk and connect them with preventive services included within their health cover, such as Bupa's Weight Management Plan, to reduce their chances of developing cardiovascular disease in the future.
Dr Srinivasan concluded: "Technology is allowing us to get far more information about our bodies than ever before, information that previously would only be available from a doctor. Understanding the data to spot any early warning signs of health concerns that might not be quite as they should be, and get treatment faster, especially when it comes to our heart health."
