WASO describes time spent doing what in sleep studies?

WASO is the total amount of time spent awake after you have fallen asleep. It sums all awakenings that occur during the sleep period once sleep has begun, from the initial sleep onset until the final awakening. This is different from the time it takes to fall asleep (sleep onset latency) or from the total time spent asleep, and it’s not about time spent in REM. WASO matters because higher values reflect fragmented or disrupted sleep and lower sleep efficiency, often seen in insomnia or other sleep disorders.
