Weekend lie-ins 'do not make up for sleep deprivation'

Weekend lie-ins 'do not make up for sleep deprivation'
    A study found that depression over the weekend does not compensate for sleep deprivation during the week.

    The researchers took two groups of healthy people and set their sleep for no more than five hours a night.

    One group had their sleep restricted to the entire study, while the other was able to catch up on the weekend.

    Both groups ate more snacks at night, gained weight, and showed signs of deterioration of metabolic health, compared to the beginning of the study.

    "In the end, we did not see any benefit in metabolic outcomes in people who slept on weekends," said lead author Chris Debner, an associate professor of integrative physiology at the University of Colorado Boulder.
    Research has shown that lack of sleep can increase the risk of a range of health problems, including obesity and type 2 diabetes, in part by promoting the desire to have a snack at night, reduce insulin sensitivity, or the body's ability to regulate blood sugar.

    In this new study, researchers wanted to know what happens when people move back and forth between a sleep-deprived working week and a two-day period of catching up.

    They took thirty six people, aged between eighteen and thirty-nine years old, and stayed for two weeks in a laboratory, where their food intake, exposure to light and sleep were monitored.

    Although the figures may seem small, experts said that this is a large number of participants to study sleep of this type.

    Participants were divided into three groups:

    One was allowed no more than five hours per night over nine nights (restricted group to sleep)
    The second was not allowed more than five hours for five days followed by the weekend where he could sleep as much as they like before returning to two days of restricted sleep (weekly recovery group)
    Three hours of sleep were allowed - nine hours per night for nine nights (control group)
    The two sleeping groups gained a small amount of weight over the course of the study (just over two.2 pounds or one kg) and became less sensitive to insulin, according to the study, published in the current journal Biology.

    While those in the recovery group saw moderate improvements on weekends (including a low intake of snacks at night), these benefits went away when the restrained sleep week resumed.

    On some health measures, the weekend recovery group was the worst.

    Insulin sensitivity decreased by thirteen percent in the sleep-restricted group, while the weekend recovery group worsened by between nine percent and twenty seven percent.

    One problem was that people who had the opportunity to go to sleep struggled to do so.

    In the end, the recovery group achieved only sixty six minutes of average sleep on weekends.

    'Regular Schedule'
    Non-research experts said that although the effects on health described in the study were small, the effect could be significant over months and years.

    They said the findings reinforced current advice that it is important to sleep enough during the week, ideally maintaining a regular sleep schedule.

    But if you are unable to maintain regular sleep and waking time, this does not mean that lying is necessarily bad for you.

    The study focused on how the restrictions on sleep and resting rest on weekends affect metabolic health, not for example mental health or cognitive ability.

    "While I think we should urge everyone to work toward a regular schedule if possible, I do not think we should tell people who do not have this luxury should not sleep during the course of the day," says Malcolm von Shantz, professor of chronology at the University of Surrey. weekend ".
