Question

during which part of the sleep cycle should you aim to wake up?
a) in the middle of the nrem stage
b) at the end
c) at the beginning
d) in the middle of the rem stage

Explanation:

Waking up at the end of a sleep cycle (either non - REM (nREM) or REM) is ideal as the body is more prepared to transition to wakefulness. Waking in the middle of nREM (deep sleep) can lead to grogginess (sleep inertia). Waking at the beginning is not helpful as the cycle has just started. Waking in the middle of REM (associated with dreaming) can also cause disorientation.

Answer:

B. At the end
