"It was rather surprising to find such an impact of short sleep duration on these injury-related behaviors and suggests that sleep deprivation may play an important role in poor judgment and decision-making among adolescents," said Janet Croft, chief of the epidemiology and surveillance branch of the National Center for Chronic Disease Prevention and Health Promotion at the Centers for Disease Control and Prevention and one of the co-authors of the study.

In 2009, Fu's group published a paper that explained the mechanisms of a short sleep phenotype in humans. In one family, carriers of the autosomal dominant phenotype sleep 6.25 hours compared to non-carrying family members, who sleep more than 8 hours per night. Fu traced the phenotype back to a point mutation in a gene called DEC2 that is associated with short sleep phenotype in humans. The mutant DEC2 has a proline-to-arginine switch at amino acid position 384, which causes the short sleep phenotype.
|
|
Transgenic mice and flies with the mutant DEC2 showed similar phenotypes. It is not currently known what other molecules DEC2 interacts with to produce the short sleep phenotype.

Television use was associated with the poorest sleep duration. Adolescent technology-use has also been linked with excessive daytime sleepiness and caffeine consumption, suggesting that technology-use may interfere with sleep and may lead to increased caffeine consumption. Longitudinal data demonstrates that time spent using technology is predictive of short sleep duration, however short sleep duration was also predictive of time spent using technology. More longitudinal research with larger sample sizes is needed to clarify the mechanisms underlying the association between technology-use and sleep during adolescence.

Short break from physical work A power nap is a short sleep that terminates before deep sleep (slow-wave sleep; SWS); it is intended to quickly revitalize the subject. Cornell University social psychologist James Maas coined the term.

Among all occupations, protective service occupations had the highest prevalence of working an alternative shift (54%). One of the ways in which working alternative shifts can impair health is through decreasing sleep opportunities. Among all workers, those who usually worked the night shift had a much higher prevalence of short sleep duration (44.0%, representing approximately 2.2 million night shift workers) than those who worked the day shift (28.8%, representing approximately 28.3 million day shift workers). An especially high prevalence of short sleep duration was reported by night shift workers in the transportation and warehousing (69.7%) and health-care and social assistance (52.3%) industries.

While players are given sufficient water, their meals are rationed, typically consisting of either a tasteless "nutrition bar" or a very small portion of a food item, e.g. a single grape or almond. However, as either a reward or part of a challenge, players are sometimes given larger amounts of more nourishing food items. Furthermore, while each pod is equipped with a proper bed, Val will often limit the amount of sleep the players get by making sure they stay awake, though the players are granted short sleep periods at times.

He was commissioned for the British Film Institute's New Directors scheme with the short Sleep starring Danny John Jules and Josephine Butler. Sleep was described by Ewen Bremner on Channel 4's Shooting Gallery as “a big, searching serious film, which in my opinion breaks out of the genre and shows us where the new filmmakers are heading”.

Cottage has made two films in Estonia, the short The Shoe Tree (winner of the Northern Lights Film Challenge) and Stranger Than Kindness (screened as part of Britspotting and shown on Estonian television ETV).

In the United States, the United Kingdom, and a growing number of other countries, a short sleep has been referred to as a "power nap", a term coined by Cornell University social psychologist James MaasMaas, James B. (1998) Miracle Sleep Cure: London: Thorsons and recognized by other research scientists such as Sara Mednick as well as in the popular press.

In rats, prolonged, complete sleep deprivation increased both food intake and energy expenditure with a net effect of weight loss and ultimately death. This study hypothesizes that the moderate chronic sleep debt associated with habitual short sleep is associated with increased appetite and energy expenditure with the equation tipped towards food intake rather than expenditure in societies where high-calorie food is freely available. Several large studies using nationally representative samples suggest that one of the causes of high obesity rates in the United States might be a corresponding decrease in the average number of hours that people are sleeping.Does the lack of sleep make you fat? , Bristol University Press Release, 7 December 2004 The findings suggest that this might be happening because sleep deprivation could be disrupting hormones that regulate glucose metabolism and appetite.

Some are of his fiancée, and others of the scenery, the Aurora and penguins. There are even images unrelated to Antarctica: horses, a Canadian Mountie on horseback, a man with a monocle in his left eye looking resplendent in a top hat and formal attire and other men with different hats. His education and upbringing shows through in some of the phrases and words he uses. He describes his life at times as a ‘ducky life’, calls a short sleep ’40 winks’, uses the term ‘by jingo’ to express his surprise at something, calls an argument a ‘roar’ and often describes something as ‘jolly nice’. He uses a phrase ‘the bally thing didn't budge’ when trying to move a sledge whereas others would write ‘d _ _ d hard work’ or use untutored grammar with a note: ‘We struggled on + on’.
