Physical activity that conforms to medical and health association guidelines is associated with a lower risk of atrial fibrillation (Afib) and stroke, according to a study by researchers at Massachusetts General Hospital (MGH), who analyzed nearly 100,000 individuals equipped with wrist-worn accelerometers to measure their movement. The researchers’ findings suggest that data from wearables, including a new generation of devices with sensors that allow for Afib detection, could provide an opportunity for the public health community to promote moderate physical activity as an effective way to improve health outcomes. The study was published in the European Heart Journal.

“Although some population-based studies have observed a lower risk of atrial fibrillation with exercise, the link has remained inconclusive in part because...
