Researchers found that a quick run on a treadmill rebalances brain activity, helping students process conflicting information with greater speed and focus. The findings were recently published in Physiology & Behavior. Test-related distress is a common experience that goes beyond simple nervousness. It involves intense worry, physical tension, a racing heartbeat, and scattered thoughts that arise before or during an evaluative situation. People facing this condition often struggle with a cognitive skill known as inhibitory control.
