A new study suggests that even light physical activity can significantly reduce the risk of stroke, heart-related complications, and premature death in people living with atrial fibrillation (AFib), the most common type of irregular heart rhythm. Researchers say the findings reinforce the importance of staying active, even for individuals who are unable to perform vigorous exercise.
The study found that simple activities such as walking, household chores, gardening, or gentle stretching were associated with better health outcomes in patients with atrial fibrillation. Participants who engaged in regular light-to-moderate physical activity had a lower risk of stroke, fewer hospitalizations, and reduced overall mortality compared with those who were physically inactive.
Atrial fibrillation causes the heart to beat irregularly and often rapidly, increasing the risk of blood clots that can travel to the brain and cause a stroke. The condition affects millions of people worldwide and is especially common among older adults. While medications remain essential for managing AFib, researchers say lifestyle changes—including regular physical activity—can play a crucial role in improving long-term health.
According to the researchers, physical activity helps improve blood circulation, supports heart function, reduces inflammation, and aids in controlling other risk factors such as high blood pressure, obesity, and diabetes. Importantly, the study found that any movement is better than none, and patients do not need to engage in intense workouts to experience meaningful health benefits.
Cardiologists advise people with atrial fibrillation to consult their healthcare providers before beginning a new exercise program, particularly if they have other heart conditions. Most patients can safely participate in low-impact activities tailored to their fitness level under medical guidance.
The researchers hope the findings will encourage more people with atrial fibrillation to incorporate regular movement into their daily routines. They emphasize that combining appropriate physical activity with prescribed medications, a heart-healthy diet, and routine medical care can help lower the risk of stroke and improve quality of life.
