Which statement about the effects of sleep deprivation on mood and academics is supported by research?

• A. It has no impact on memory
• B. It reduces attention, memory, and grades, and increases irritability
• C. It improves mood
• D. It only affects physical health

Answer: (B)

Sleep is essential for how we think and feel, especially in learning environments. When sleep is lacking, attention suffers and the ability to concentrate drops, which makes studying and in-class tasks harder. Memory processes—both encoding new information and retrieving what’s learned—rely on adequate sleep, so sleep deprivation often leads to poorer memory performance and weaker grades. At the same time, sleep loss disrupts emotional regulation, which tends to increase irritability and moodiness. Because research consistently shows these patterns, the statement that sleep deprivation reduces attention, memory, and grades, and increases irritability is the best fit. It’s not supported that sleep loss has no memory impact, that it improves mood, or that it affects only physical health—those do not align with what studies repeatedly find about mood and academic functioning.
