In a move that underscores the profound role of physical activity in improving overall health, a recent scientific study has revealed that regular exercise can directly help reduce stress, not only by improving mental well-being but also through biological effects within the body itself.
According to SciTechDaily, these findings come from a study published in the journal Sport and Health Science. The study, the first of its kind, tracked the effects of aerobic exercise on the body over a full year.
The research team from the University of Pittsburgh conducted the study, focusing on evaluating the impact of adhering to physical activity recommendations, particularly engaging in approximately 150 minutes of moderate- to vigorous-intensity aerobic exercise per week.
The study included 130 adults, divided into two groups. One group followed a regular exercise program for a full year, while the other group received general health guidelines without altering their daily activity patterns.
The results revealed a significant decrease in cortisol levels among participants who exercised regularly, compared to the control group. This hormone is responsible for regulating several vital functions, such as sleep, immunity, and memory. However, chronically elevated cortisol levels are linked to an increased risk of heart disease, metabolic disorders, and mental health problems.
These findings are particularly significant because they were based on a long-term randomized trial, rather than mere correlational observations as in previous studies. This lends them greater weight in explaining the relationship between exercise and stress reduction. Nevertheless, the researchers pointed out that this relationship does not imply that exercise is the sole factor, as other factors such as nutrition and lifestyle also play a crucial role.
The results also indicated that aerobic exercise may contribute to improved emotional regulation and potentially slow some aspects of brain aging, thus reinforcing its role in supporting both physical and mental health.
The researchers concluded by emphasizing that committing to physical activity, even for just 150 minutes per week, can be a simple and effective way to reduce stress and improve quality of life, especially in light of increasing daily pressures.
