Which of the following is a mental benefit of exercise?

• A. Improved confidence
• B. Relief of stress/tension and stress-related illnesses
• C. Improved posture
• D. Meeting new people

Answer: (B)

Regular exercise boosts mental well-being by improving mood and reducing stress. The strongest mental benefit described is relief of stress and stress-related illnesses, because it directly targets mental health—lowering tension, anxiety, and the impact of stress on the body. Exercise triggers mood-enhancing chemicals and helps regulate sleep and stress hormones, supporting a calmer, more resilient mind. The other options point to outcomes that are physical (posture), social (meeting new people), or less directly tied to mental health (confidence), so they don’t fit as clearly as the direct stress-relief benefit.
