How does regular exercise influence cognitive function in early adulthood?

• A. It reduces creativity
• B. It is associated with improved memory, attention, and executive function
• C. It has no impact
• D. It worsens sleep

Answer: (B)

Regular exercise can positively influence cognitive function in early adulthood. Physical activity increases blood flow to the brain and delivers more oxygen and nutrients, supporting brain health. It also raises levels of brain-derived neurotrophic factor (BDNF) and other growth factors, which promote neuroplasticity and the growth of neural connections, especially in the hippocampus and prefrontal cortex. These brain changes help with memory formation, learning, attention, and executive control—planning, problem-solving, and maintaining focus. In addition, regular exercise often improves sleep quality and mood while reducing stress, all of which bolster cognitive performance. Thus, the best answer is that exercise is associated with improved memory, attention, and executive function. The other statements don’t fit the well-supported pattern: exercise is not known to reduce creativity, it generally has at least some positive or neutral impact on cognition, and it often improves, not worsens, sleep.
