Which statement best describes a NOT function of sleep?

• A. Immune system support and disease recuperation
• B. Reduced caloric use
• C. Glymphatic clearance of wake-related toxins
• D. Increased muscle protein synthesis during wakefulness

Answer: (D)

Sleep supports restorative processes that sustain the body's defenses and repair work. Immune function is bolstered during sleep, helping disease resistance. The glymphatic system, which clears wake-related waste from the brain, is more active in sleep, especially deep sleep, promoting brain health. Energy use is minimized during sleep, allowing resources to be redirected toward repair and maintenance. Growth hormone release during slow-wave sleep drives muscle protein synthesis and tissue repair, mostly happening while you’re asleep. The idea that sleep would increase muscle protein synthesis during wakefulness doesn’t fit this pattern, since the wake period is when activity, feeding, and energy expenditure dominate and sleep-driven anabolic processes aren’t in play.
