Total sleep time has been studied in 4 papers since 2022: 4 observational studies in people. The newest paper, May 4, 2023: “Disturbance of sleep maintenance, but not sleep duration, activates nuclear factor-κB and signal transducer and activator of transcription family proteins in older adults: sex differences”.

What did studies of Total sleep time find?
2Studies of Total sleep time measured 2 outcomes; the most studied are NF-κB signaling (1 study) and navigation task performance (1).
NF-κB signaling

Total sleep time has no effect on navigation task performance in humans.
“Total sleep time was not linearly associated with the navigation tasks (ps > .087).”
