Light exposure, and in particular the light-dark cycle, is the primary synchronizer of the circadian clock to the 24-hour day, although sleep, physical activity, meal timing, and temperature can also synchronize daily rhythms.
“Light exposure, and in particular the light-dark cycle, is the primary synchronizer of the circadian clock to the 24-hour day, although sleep, physical activity, meal timing, and temperature can also synchronize daily rhythms [40,41].”

Inter-individual differences in circadian phase and chronotype are due to both endogenous differences in the circadian period and exogenous differences in exposure to external factors that can shift circadian rhythms.
“Inter-individual differences in circadian phase and chronotype (i.e. the behavioral expression of individual circadian rhythmicity) are due to both endogenous differences in the circadian period and exogenous differences in the exposure to the external factors which can shift an individual’s circadian rhythms [40].”

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.
