Boston, MA – A new study suggests that exercise not only benefits mental and heart health but also plays a crucial role in reducing stress signals in the brain and decreasing the risk of cardiovascular disease. Researchers from the Mass General Brigham Biobank analyzed data of over 50,000 adults around age 60 and found compelling associations between physical activity and improved brain health.
Lead study author Dr. Ahmed Tawakol explained that individuals who engaged in more exercise exhibited a graded reduction in stress-related signals in the brain, ultimately lowering the risk of heart disease. The study, published in the Journal of the American College of Cardiology, utilized surveys, brain imaging, and digital records to track the effects of exercise on participants.
Dr. Andrew Freeman, a director of cardiovascular prevention and wellness, emphasized the significant benefits of exercise in reducing cardiovascular disease risks, especially for individuals with a history of depression. The study revealed a greater than twofold increase in exercise benefits among individuals experiencing depression compared to those without a history of depression.
According to Dr. Karmel Choi, a clinical psychologist and study coauthor, the relationship between exercise and stress modulation is particularly encouraging for individuals susceptible to stress-related conditions. The study also found that exercise reduced stress signals and increased prefrontal cortical signals in the brain, leading to favorable changes associated with cognitive processes and behavior control.
While the study highlighted the positive associations between exercise and brain health, researchers caution that further investigations are necessary to determine the underlying mechanisms responsible for these benefits. Dr. Freeman recommended incorporating at least 30 minutes of physical activity into daily routines, emphasizing the importance of engaging in activities that individuals genuinely enjoy for maximum stress-relieving effects.
