Exposure to light versus way of life: effects on sleep patterns of a teenager—case report
Abstract
The natural light/dark cycle is the primary synchronizing cue in animals; although artificial light has an influence upon contemporary humans. Nevertheless, one's way of life may have a strong impa...

Variations in chronotype between urban and rural areas within the same country have been observed in Japanese adolescents and in adults in Brazil, India, and elsewhere.
“In addition to country-specific differences, variations in chronotype between urban and rural areas within the same country have been observed in Japanese adolescents (53, 59, 60) and in adults in Brazil, India, and elsewhere (61–63).”

“A case report describes a student in Brazil who had a 40-minute delay in sleep on the weekends when electric lights were installed.(55) Bright light (8,000 lux) given at 7 pm or at 9 pm reduced nighttime sleepiness in students who had an evening preference and those with a later onset of melatonin.”

“…social events – such as sport activities – can now be practised outdoors in the evening thanks to artificial lighting and a major impact of electrification is to alter the ‘light and day input’ through controlling artificial light during solar darkness (Wright et al., 2005; Louzada et al., 2004).”

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.
