A 12-month clinical trial found that consistent aerobic exercise lowered long-term cortisol levels, showing your body can reduce chronic stress when you train it regularly
About 150 minutes per week of moderate-to-vigorous movement was enough to create measurable changes, making stress reduction achievable with a realistic routine
Cortisol is not just a stress hormone but a survival tool that stabilizes blood sugar, yet chronically high levels shift your body into a constant state of dysfunction
Exercise improves your stress response even without weight loss, meaning your internal systems become more resilient before you see physical changes
Combining steady exercise, enough carbohydrates, and proper recovery helps break the stress cycle at its root so your body stops reacting as if it's under constant threat
