最佳午睡 (Power Nap)

Power Nap : a short sleep which terminates before the occurrence of deep sleep.

The power nap is thought to maximize the benefits of sleep versus time. It is used to supplement normal sleep, especially when a sleeper has accumulated a sleep deficit.

The short duration of a power nap is designed to prevent nappers from sleeping so long that they enter a normal sleep cycle without being able to complete it. Power naps restore wakefulness and promote performance and learning.
