What is a common effect of regular physical activity on mental health?

Regular physical activity has a well-documented positive impact on mental health, primarily by improving mood. Engaging in exercise stimulates the release of endorphins and other chemicals in the brain that reduce feelings of stress and anxiety, fostering a sense of happiness and well-being. This biological response is often referred to as the "runner's high," which is a state of euphoria experienced after prolonged exercise.

In addition to the immediate effects on mood, consistent physical activity can lead to longer-term improvements in mental health. It can reduce symptoms of depression and anxiety, and even enhance cognitive function over time, contributing to better overall mental wellness. The act of exercising also provides a sense of accomplishment and can serve as a valuable outlet for relieving everyday stress.

Focusing on the other options highlights why they do not align with the overall benefits of exercise on mental health. Increased stress and heightened anxiety contradict the common understanding of exercise’s effects, which are generally calming and stress-relieving. Decreased cognitive function runs counter to research that shows physical activity is typically beneficial to brain health and cognitive performance.
