The phrase "actual sleep time" is correct and usable in written English.
You can use it when discussing the specific duration of sleep that a person actually experiences, as opposed to the time spent in bed or attempting to sleep.
Example: "After analyzing my sleep patterns, I found that my actual sleep time averages only six hours per night."
Alternatives: "true sleep duration" or "real sleep time".
In this study, we subjected 22 healthy males (aged 21.8 ± 1.9 years) to a 40-min nap trial followed by 80 min of wakefulness repeated over 28 h, and investigated the relationship between various sleep parameters and the discrepancy (ΔST) of time estimation ability (TEA) during sleep, defined by the difference between actual sleep time (ST) and subjective sleep time (sub-ST) in each nap interval.
Polar apps provide calories burned, training tips and tracking of sleep metrics such as duration, actual sleep time and awake/asleep/interruption times.
Nocturnal dips in systolic blood pressure calculated by actual sleep time were compared with those from a preset sleep time.
Bed time, actual sleep time, actual time awake, and sleep efficiency did not differ between the two groups.
Sleep onset latency and sleep efficiency, defined as the actual sleep time divided by the time in bed, are also obtained with the PSQI.
Beyond the issue of discerning actual sleep time to identify blood pressure dipping, there is the question of general blood pressure reproducibility.
The MCTQ assesses actual sleep times separately for work and work-free days.
In our study, approximately one-third of the adolescents with type 1 diabetes were found to have an initial attenuated decline in nighttime systolic blood pressure on ABPM, despite use of data from actual sleep times for analysis.
Actual sleep, not time spent in bed.
The nocturnal dip in systolic blood pressure was again measured using actual reported sleep time.
For aim 2, blood pressure monitoring from 98 patients using actual reported sleep time was reviewed.
