Study shows that exercise decreases stress-related brain activity, lowering risk of heart disease

A new study published in the Journal of the American College of Cardiology suggests that exercise not only benefits physical health but also plays a crucial role in reducing stress signals in the brain, ultimately decreasing the risk of cardiovascular disease.

Researchers analyzed data from over 50,000 adults around the age of 60 and found a direct correlation between exercise and a reduction in stress-related signals in the brain. Lead study author Dr. Ahmed Tawakol, a cardiologist at Mass General Hospital, noted that individuals who exercised more showed a graded reduction in stress signals, leading to a decreased risk of heart disease.

Interestingly, the study also revealed that individuals with a history of depression experienced even greater benefits from exercise, with a twofold increase in benefits compared to those without depression. The relationship between the amount of exercise and the decrease in cardiovascular risk varied depending on the individual’s history of depression.

Dr. Andrew Freeman, director of cardiovascular prevention and wellness at National Jewish Health, emphasized the importance of finding an exercise routine that is enjoyable and sustainable. He recommended aiming for 30 minutes of breathless physical activity each day, regardless of the type of activity.

Overall, the study highlights the significant impact of exercise on both mental and physical health, emphasizing the importance of incorporating regular physical activity into daily routines for overall well-being.
