All of these evenings to spend, trolling Facebook, message friends and learn for tests can a toll on young people plans, a new study suggests.
Young people, who rested on average less than eight hours nights sleep tend, more fatty foods and snacks better eating high-calorie than their peers, according to the study published in the journal of sleep.
These unhealthy eating habits can in the course of time and can cause that deeply rooted habits and weight gain, says Susan Redline, MD, author of the study sleep principal and Professor of medicine at Harvard Medical School, Boston.
Research "clearly showed [who]" get people insufficient amounts of sleep are more likely to be overweight and weight increase in over time ", explains Dr. Redline." «"" Among young people, who are deprived sleep rather more calories consume and eat food and food much more high fat high density.»
The study shows that patterns caused sleep youth overweight, but Dr. Redline and his colleagues concluded that the 18% of young people in the study, the less likely eight hours were obese sleep adolescents get average weight.
It is not clear why less sleep refrigerator more frequently to send young people. A declaration includes the hormone leptin and ghrelin, to regulate the appetite. Having not enough sleep has shown that the production of these hormones to reduce, can make a print person appetite and cravings of fuel for the high-calorie snacks.
The social and cultural factors could play a role, said Kristen Knutson, PhD, Assistant Professor of medicine, nursing, lung, and criticism of the University of Chicago. Although in their analysis, Dr. Redline and his colleagues age, race and education of parents into account could parenting, style and other factors, the data have influenced hard to identify.
"Is no fleas in the House [youngsters] are the food, not, select", says Knutson, was included in the study, but research on the effects on the health of short sleep.
It may also be, who spend more time awake offers more opportunities for snack, said Dr. Redline.
This study is focused on 240 young people aged from 16 to 19 years, the part of a study more on sleep and health. Researchers of the sleep of young people the duration have measured monitors with wrist and she asked two separate for the food list that had eaten in the previous 24 hours.
Young an average of 7.5 hours sleep every night of the week - is the American Academy of medicine, sleep well shy of nine hours for this age group. Only about a third of young people slept for at least eight hours.
Of their colleagues rested better, deprived of sleep adolescents received more than about 2% of their daily calories from fat and calories of less 3% carbohydrates, which resulted in study. And young people who slept less than eight hours were rather their calories snacks - mainly girls get.
"This study comes in the real world and concludes that short sleep with selection of food and an increase in appetite, says Is…associated Knutson."
Even if snacks of part of a healthy diet can be to eat, at the time of the day, which is poorly with aligned are the inner clock may change metabolism and a person more likely to weight, according to Dr. Redline. More tired young people consume a significant amount of calories between 05 and 07, it notes.
"" "Young people tend to"phase delay", we call so the natural inclination of the body, later press towards the sunset", explains Dr. Redline. "School early to get up to then, are they are sleep deprived and food may within hours early, when their metabolic system not really at is is to occupy calories.".
The results of the study are used should be as a reminder of young people and parents who so much - not just diet and exercise - sleep is a key element of a healthy lifestyle, says Knutson.
"We need to inform the parents to sunset is important for the health of their children", she said.
