Influence of back angle on the quality of sleep in seats
Abstract
Nocturnal sleep was assessed electroencephalographically in 9 males aged between 29 and 48 (mean 36·5) years in bed and in three seats with back angles to the vertical of 49·5° (sleeperette), 37·0° (reclining seat) and 17·5° (armchair). Sleep in the sleeperette did not differ from that in bed, but in the reclining seat the duration of sleep was reduced and the amount of awake activity was increased. Sleep in the armchair was markedly worse than in any of the other three conditions. Total sleep time was shorter and awake activity was increased with more awakenings. Sleep efficiency was also reduced. It would appear that adequate sleep may be obtained in seats as long as the back angle with the vertical approaches 40°.

Sleep onset and maintenance depend on sleep-permissive and wake-promoting conditions such as posture.
“In real life, sleep onset and maintenance also depend on whether some seemingly trivial yet crucial conditions are met, like having attained an appropriate posture.”
From Sleep, vigilance, and thermosensitivity (2012) · cites this paper as [62]
Being in a supine position is a sleep-permissive condition, whereas being upright is a wake-promoting condition.
“Being in a supine position is being in a sleep-permissive condition, whereas being upright is being in a wake-promoting condition [2, 13, 14, 18, 49, 62].”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
