Proper Sleep sustains which of the following?

• A. Brain function
• B. Immune system
• C. Recovery after physical activity
• D. All of the above

Answer: (D)

Proper sleep sustains brain function, immune defenses, and recovery after physical activity. When you sleep well, your brain can consolidate memories, regulate mood, and maintain attention and decision-making abilities; insufficient sleep impairs these cognitive safeguards and slows reaction time. Sleep also supports the immune system—cytokine production and immune cell activity ramp up during rest, and adequate sleep helps vaccines work better and infections be fought off more effectively. For recovery from exercise, sleep is when repair and rebuilding occur: growth hormone release peaks, protein synthesis rises, glycogen stores are replenished, and inflammation is reduced, helping you recover faster and perform better next time. Because sleep benefits all three areas, choosing the option that includes all of them is the best fit.
