WASO stands for which phrase?

WASO measures the total time you are awake after you first fall asleep until you finally wake up for the day. It captures how fragmented or interrupted your sleep is during the main sleep period. The standard term for this is Wake After Sleep Onset, so this option is the best fit. This concept is tied to sleep continuity and affects sleep efficiency—the more time spent awake after sleep onset, the lower the sleep efficiency. It’s different from sleep onset latency, which is the time it takes to fall asleep after trying to sleep. The other phrases don’t reflect the established term used in sleep studies.
