Want Less Stress? Landmark Study Points to a Simple Habit

A year-long randomized clinical trial found that adults who did 150 minutes of moderate-to-vigorous aerobic exercise per week had lower long-term cortisol than a control group.

The findings provide rare causal evidence that regular aerobic exercise can measurably reduce the body’s stress response.

This could have important implications for mental health, disease prevention, and public health exercise guidance.
