Which of the following is a recognized benefit of regular physical activity for adolescents?

• A. Increased anxiety and depression
• B. Improved mood
• C. Worsened sleep quality
• D. Decreased cognitive function

Answer: (B)

Regular physical activity tends to lift adolescents’ mood by triggering biochemical and psychological changes that help regulate emotions. When you move, the body releases feel-good chemicals like endorphins and other neurotransmitters, and it can also lower stress hormones. Beyond biology, exercise provides a sense of accomplishment, improves self-esteem, and often enhances sleep and social interaction, all of which contribute to a steadier, more positive mood.

That’s why improving mood is the best choice. The other options describe outcomes that aren’t benefits of regular activity: anxiety and depression would be worsened rather than improved, regular activity generally supports sleep quality rather than worsening it, and rather than decreasing cognitive function, many studies show improvements in attention, memory, and executive function with consistent exercise.
