Exercise changes the brain in a way that helps heart health, especially for people with depression

A new study suggests that exercise not only benefits mental and heart health, but it also reduces stress signals in the brain, leading to a lower risk of cardiovascular disease. The study analyzed data from over 50,000 adults and found that individuals who exercised more had a graded reduction in stress-related signals in the brain. Furthermore, the study discovered that people with a history of depression experienced a greater benefit from exercise in terms of cardiovascular disease reduction. The findings highlight the importance of exercise in reducing stress and improving overall health.
