Previous research indicates that lack of sleep increases the risk of Diabetes and obesity. So far, however, was not clear whether the “Catch up” from sleep could counteract at the weekend this Trend. The scientists working with Prof. Kenneth Wright of the University of Colorado in Boulder, according to their study, however, this is not the case.

they found that even after a long night with a long Sleep, the benefits are only temporary. At the latest, in the middle of the following week, the metabolism is just as – or even more – disturbed, as if you had not rested.

say the researchers, is not clear, however, whether this is the case, when charging, only occasionally or with little sleep loss the batteries on the weekend. This is a Back and Forth but in the normal state, it can do much damage.

body clock

affected In the study, 36 people attended, who spent 13 nights in the laboratory. The first three nights were to sleep all of the participants for eight hours. A part of participants received for the remainder of the study, eight hours of sleep. The remaining Participants were divided into two groups, which spent five hours per night in bed.

a group could, in turn, after four nights, decide how long you wanted the next two nights sleep. The researchers found that the lost hours could not be recovered and the internal clock suspended more than when the sleep pattern remained the same.

Finally, the weekend. Five days of work done. Sleep! The thinks of so many. But who does not know the feeling of lethargy after rich 12 hours of sleep? The half day was too much?

lack of sleep does weight

In the first three weeks, all subjects had to adhere to a strict diet. Then they were allowed to eat what they wanted. With the new diet, all showed an increase in calories consumed.

Those who had slept during the entire duration of the study consistently eight hours per night, showed no change in the body to call weight. The Participants in the other two groups, brought with them, however, after an average of 1.5 kg more on the scale. At the same time, they showed a reduced sensitivity to the hormone Insulin, which plays a key role in the regulation of blood sugar levels.

The researchers believe that these effects could be at least partially due to the fact that on sleep-deprivation days is nibbled. That could disturb, in their opinion, the metabolism in different ways. (lum)
