WASO stands for which phrase?

Explanation:
WASO measures the time you are awake after you’ve fallen asleep, showing how well sleep is maintained through the night. It reflects sleep continuity, with higher values indicating more awakenings or longer wake periods after sleep onset. The term stands for Wake After Sleep Onset. Other phrases don’t describe this concept: Wake After Sleep Offset would refer to wake time after the final awakening and isn’t the standard term; Wake After Stage Of Sleep isn’t used; Wake Before Sleep Onset describes wakefulness before sleep begins, not after sleep has started. For example, if you sleep from 11 pm to 7 am and spend 60 minutes awake after initially falling asleep, your WASO is 60 minutes.
