Should I use a smartwatch to track my health data? A doctor explains

The use of smartwatches for tracking fitness and health has become increasingly popular. In the US, over a quarter of the population wore a smartwatch for health and fitness tracking in 2023, and this number is projected to exceed 100 million by 2026. Smartwatches resemble wristwatches and can connect to smartphones, allowing users to access various features. Many smartwatches also offer fitness and health tracking capabilities, including step counting, which has been shown to reduce the risk of heart disease and premature death. Active individuals, such as runners and triathletes, can utilize smartwatches to monitor heart rate and stay within their targeted zones during exercise. However, it is important to note that smartwatches are not approved for diagnosing heart attacks. While some smartwatches claim to detect irregular heart rhythms, it is advisable to consult with a healthcare professional for further evaluation if such a notification is received. The accuracy of smartwatches in measuring oxygen levels and blood glucose is variable, and dedicated equipment is recommended for those who require accurate measurements in these areas. Smartwatches can also track sleep patterns, providing information on sleep duration and quality. This data can be helpful for individuals making changes in their sleep environment and monitoring recovery. Ultimately, the use of smartwatches for health and fitness should be personalized and not add unnecessary pressure or stress. It may be beneficial for some individuals to take a break from data tracking and listen to their bodies, as exercise should be enjoyable.
