Study: A Simple Habit May Reduce Stress and Restore Body Balance

A recent scientific study has revealed that regular exercise may contribute to reducing stress levels through a direct impact on the body's biology, not just its psychological state. According to SciTechDaily, the study, published in the journal Sport and Health Science, was based on a first-of-its-kind clinical trial that tracked the effects of aerobic exercise on the body over a full year.

The research was led by a team from the University of Pittsburgh and focused on studying the impact of adhering to physical activity recommendations, particularly 150 minutes of moderate to vigorous aerobic exercise per week. The study included 130 adults, divided into two groups: one group followed a regular exercise program for a year, while the other received general health guidelines without changing their activity levels.

During the study, researchers monitored several indicators, most notably cortisol levels, the so-called stress hormone, along with measurements of physical fitness and brain function.

A Significant Decrease in Stress Hormone

The results showed that participants who exercised regularly experienced a significant decrease in cortisol levels over the long term, compared to the other group. Cortisol is essential for regulating vital functions such as sleep, immunity, and memory, but chronically elevated levels are linked to an increased risk of heart disease, metabolic disorders, and mental health issues.

These findings are particularly significant because most previous studies relied on correlational observations, while this study was based on a long-term randomized trial, giving it greater strength in explaining the relationship.

However, the researchers point out that the results demonstrate a strong link between exercise and stress reduction, without asserting that exercise is the sole contributing factor, as other factors such as lifestyle and nutrition also play a role. The results also suggest that aerobic exercise may contribute to improved emotional regulation and potentially slow some aspects of brain aging, thus reinforcing its role in supporting overall health.

The study confirms that committing to regular physical activity, even at a rate of 150 minutes per week, can be a practical and direct way to reduce stress and improve quality of life. In light of increasing daily pressures, sports seem like a simple but effective option to support physical and mental balance in the long term.
