Sleep latency is defined as which of the following?

Explanation:
Sleep latency measures how long it takes to fall asleep after lights out. In polysomnography, it’s the time from lights out to the first 30-second epoch of sleep (any sleep stage). This distinguishes it from REM latency (time to the first REM period) and from wake after sleep onset (time spent awake after sleep begins) or other nonstandard wake measures.
