Meach of us went late for the finals, to work overtime, or to watch cartoons until the early hours of the morning, thinking that we could catch up with all that had been lost of sleep during the weekend. Research published Thursday in Current biologysuggests, however, that lack of sleep during the week has adverse health consequences, even if you manage to sleep all weekend.
In a small study, researchers in Colorado found that sleeping only five hours a night was associated with health consequences, such as eating more after dinner, gaining weight, releasing melatonin, a sleep-related hormone, and reducing insulin sensitivity for the whole body. More importantly, these effects do not disappear after a weekend of sleep as much as you want if your unhealthy sleep patterns resume after the weekend.
"For the participants of the weekend recovery group, ad libitum the weekend's recovery sleep did not prevent one of these metabolic derangements from being assessed during recurrent insufficient sleep after the weekend, "write the researchers, led by first author Christopher Depner , Ph.D., Research Assistant in Integrative Physiology at the University of Colorado. Rock.
Weekend sleep makes no difference
The 36 participants in the study were divided into three groups: the control group (eight people) had nine solid hours each night, while the two experimental groups (each 14) slept five hours.
After five nights of insufficient sleep, one of the experimental groups had the chance to recover with ad libitum sleep for two nights, while the other group has no recovery time. In both groups who had insufficient sleep, participants presented weight gain, greater eating after dinner, circadian disruption and insulin insensitivity. These effects appeared independently whether the participants had the chance to sleep later during the weekend.

Serious health consequences
Most of the health consequences they've observed are usually associated with a sleep disturbance, but eating more after dinner may seem a little strange. Researchers say that eating more calories at the wrong time of the day is associated with metabolic disruption, and that the private sleep group is eating almost 500 more calories after dinner, the well-rested group suggests that lack of sleep leads to many metabolic pathways.
These findings support a growing body of scientific research that proves what your parents have always blamed you for: Getting enough sleep is really important.
A similar study conducted in 2018 in Scientific reports have shown that people who sleep well tend to have better heart and metabolic health, while those who do not sleep enough have a host of health risk factors, such as increased weight, increased risk of seizure cardiac or stroke, high blood pressure and higher blood sugar levels. The new study shows the same results, but it adds an essential detail: the recovery of sleep at the weekend will not solve these health problems if you do not go back to sleep on Monday night.
Abstract: People generally increase the amount of sleep on the weekend to recover from sleep loss during the work week. What he's doing ad libitum Weekend recovery sleep prevents metabolic derangement caused by recurrent insufficient sleep is unknown. Here we assessed sleep, circadian rhythm, energy intake, weight gain and insulin sensitivity during prolonged sleep failure (9 nights) and recurrent sleep insufficiency after ad libitum recovery sleep on weekends. Healthy young adults were randomly assigned to one of the following three groups: (1) control (CON: sleep options of 9 hours, n = 8), (2) sleep-free sleep restriction of weekend recovery (SR, 5 h sleep options, n = 14) and (3) sleep restriction with weekend recovery sleep (WR, insufficient sleep during a 5-day work week, then 2 weekend recovery days, then 2 nights of insufficient sleep, n = 14). For the SR and WR groups, lack of sleep increased energy intake and body weight after dinner compared to baseline values. during ad libitum Recovery sleep on weekends, participants slept cumulatively 1.1 h more than baseline, and energy intake after dinner decreased compared to lack of sleep. However, during periods of insufficient recurrent sleep after the weekend, the circadian phase was delayed and energy intake after dinner and body weight increased from baseline. In RS patients, the total insulin sensitivity of the body decreased by 13% in case of insufficient sleep compared to baseline, and in the ER, the total insulin sensitivity of the body, hepatic and muscle decreased from 9% to 27% during recurrent insufficient sleep. In addition, during the weekend, the total sleep time was lower for women than for men, and energy intake decreased to baseline levels for women, but not for men. Our findings suggest that weekend recovery sleep is not an effective strategy for preventing metabolic dysregulation associated with recurrent insufficient sleep.
