Which statement correctly describes sleep extension and napping?

• A. Napping increases total sleep time over several days.
• B. Sleep extension increases total sleep time over several days, while napping provides short-term daytime rest to reduce fatigue.
• C. Sleep extension is the same as napping and provides no difference.
• D. Sleep extension applies only to post-exercise energy.

Answer: (B)

Sleep extension means adding to total sleep time by increasing nightly sleep across several days, typically by going to bed earlier or waking up later. This builds longer, consistent sleep opportunity that accumulates into more sleep overall and supports recovery, mood, and performance over time. Napping, in contrast, is a daytime rest intended to provide immediate relief from fatigue and a quick boost in alertness; it helps in the short term but doesn’t replace the longer-term benefit of extending nightly sleep. The statement captures the practical distinction: extending nighttime sleep grows total sleep time over multiple days, while a daytime nap delivers short-term rest to reduce fatigue. The other ideas mix these roles or misstate their scope, such as equating sleep extension with napping or limiting sleep extension to post-exercise energy.
