Exercise Reduces Stress Signals and Enhances Heart Health, Study Finds


Exercise has long been known to have numerous physical and mental health benefits. In a recent study, researchers from Mass General Brigham Biobank have discovered that exercise not only improves mental health and heart health individually, but it also establishes a positive link between these two aspects. Their findings provide further evidence for the benefits of exercise in reducing stress signals and mitigating the risk of cardiovascular disease. Let’s delve into the study’s details and understand the implications.

The Study’s Key Findings

Exercise’s Impact on Mental Health and Heart Health

New research strengthens the existing understanding that exercise has a positive impact on mental health and heart health. The study conducted by Mass General Brigham Biobank involved over 50,000 adults around the age of 60. The researchers analyzed data regarding the participants’ physical activity, brain activity related to stress signals, and digital records of cardiovascular events.

The Role of Exercise in Reducing Stress Signals in the Brain

According to the study’s lead author, Dr. Ahmed Tawakol, exercise demonstrated a graded reduction in stress-related signals in the brain. This reduction is associated with a decreased risk of cardiovascular disease. The findings indicate that exercise can be an effective tool in reducing heart disease risks through its stress-modulating effects. The study also revealed that individuals with a history of depression may gain even greater benefits from exercise.

Assessing the Exercise-Depression Connection

The researchers found that individuals with depression experienced a more than twofold increase in the benefits derived from exercise compared to those without depression or a history of depression. Moreover, the relationship between exercise and the level of cardiovascular risk reduction varied in individuals with and without depression. Exercise continued to provide benefits for those with depression, even with a greater amount of time spent on physical activity.

The Prefrontal Cortex and Heart Disease Risks

The study indicated that exercise resulted in a reduction of stress signals and an increase in prefrontal cortical signals. Both of these changes in the brain are considered favorable. The prefrontal cortex, responsible for executive function and behavioral control, experiences improvements as a result of exercise. On the other hand, stress signals in the brain are linked to negative health outcomes such as inflammation, higher blood pressure, and arteries’ thickness or hardening.

Expert Perspectives

Expert Opinion from Dr. Andrew Freeman

Dr. Andrew Freeman, director of cardiovascular prevention and wellness at National Jewish Health in Denver, emphasizes the importance of lifestyle changes. He highlights the low cost and substantial improvements exercise offers, comparing them favorably to medications. Dr. Freeman suggests incorporating exercise into daily routines as a cost-effective tool for improving overall well-being.

Expert Opinion from Dr. Karmel Choi

Dr. Karmel Choi, a clinical psychologist and assistant professor at Harvard Medical School and Massachusetts General Hospital, emphasizes the significance of the study’s findings. She highlights that exercise is even more beneficial for individuals prone to stress-related conditions, such as depression. She encourages individuals to take advantage of exercise and its stress-modulating effects, which can have an encouraging impact on their mental and cardiovascular health.

Concluding Remarks

The recent study conducted by Mass General Brigham Biobank provides valuable insights into the positive effects of exercise on mental health and heart health. Exercise contributes to a reduction in stress signals, which in turn lessens the risk of cardiovascular disease. Furthermore, the impact of exercise varies depending on an individual’s history of depression. These findings highlight exercise as a cost-effective and accessible means to mitigate the risk of heart disease and improve overall well-being. Embracing exercise as a part of our daily routines can lead to long-lasting benefits.
