Abstract

Abstract The effect of daytime light conditions on the sleep habits and morning–evening preference of Japanese junior high school students (415 girls and 411 boys; age range, 12–15 years old) was studied. Students who were outdoors during the short break between classes or their lunch‐time break were more morning‐type people than those who remained indoors. Students who shut out the light from outside showed longer subjective sleep latency and appealed more shallow sleep rather than those who did not. Sunlight can be an important factor for the timing of sleep based on the circadian system of Japanese young students.

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.
