The old saying goes that “debt repayment, heaven and earth”, for people usually because of work, entertainment stay up late owed “sleep debt”, should also be paid back in time. Otherwise, long-term debt is even more or more, and over time, “sleep debt” can lead to a range of health problems, including obesity, type 2 diabetes, heart disease and depression, and even accidental injuries, which are life-threatening.
Some people take a nap during the day, and others try to pay off their “sleep debts” by taking up their weekend sleep. For those trying to get up for the weekend, a study published online by French researchers in the journal Sleep Medicine is bad news: More than a third of adults don’t get enough sleep during the week, and few get it back on weekends.
To assess sleep status in adults, the researchers studied 12,367 subjects. The subjects were aged 18-75 and were surveyed on weekdays, total weekend sleep times, and night and day sleep time.
The researchers analyzed the sleep durations of the subjects and compared the sleep duration spent by the U.S. Sleep Foundation with “7-9 hours for adults aged 18-64 and 7-8 hours for adults aged 65 and over.”
Analyzing the subjects’ sleep data, the researchers found that the average sleep time during the week was 6 hours and 42 minutes, that the weekend was 7 hours and 26 minutes, that 27.7 percent of the subjects thought they were missing for one hour a day, and that 18.8 percent of the subjects thought they were severely sleep-deprived and that they were missing more than 1.5 hours a day.
Further analysis found that 35.9 percent of the subjects actually slept less than six hours;
However, 27.4% of the subjects took at least one nap (8.3 minutes) a week during the working week, and 32.2% took a nap on the weekend (13.7 minutes) to supplement their sleep.
Of those with severe sleep deprivation, only 18.2 percent made up for the lack of sleep on weekdays on weekends by sleeping early and getting up late, 7.4 percent took naps to supplement their sleep on weekends, and 75.8 percent did nothing to supplement their severe lack of sleep during the week.
Dr Damien Leger, author of the study and a member of the Public Assistance Hospital in Paris, Said: “Night-time overtime, shift work, long commutes between work and family, and excessive attachment to electronic technologies, such as smartphones, have led to an increase in sleep deprivation among more people and 75 per cent of those who are severely sleep-deprived, who do not find the right way to supplement their sleep.” The reasons are not complicated, such as not having time to sleep, poor sleep conditions in the environment, difficulty sleeping, work, family pressure, sleep, etc. “
“Lack of sleep can cause damage to the whole body and affect function at all levels of the body, from DNA to cells, to organs, to performance at work or exercise. There is no simpler and more effective remedy than getting enough sleep every day. Getting enough sleep a day is like eating a healthy diet, and eating a healthy diet two days a week doesn’t reverse the harm of eating unhealthy foods for the remaining five days, and so does sleep,” added Dr. Damien Leger.
In addition, existing studies have not yet been conclusive on the usefulness of weekend supplements. A study published in the Journal of Sleep Research found that less than five hours of sleep a working day was associated with an increasein mortality rate, but people who had a weekend make-up may be able to offset the risk.
According to another study published in Current Biology, weekend supplementation can lead to reduced muscle and liver insulin sensitivity and reduced blood sugar regulation, and waking up late on weekends can cause Sunday night’s biological clock to be delayed, making it difficult to fall asleep even if you have to get up early on Mondays.
To reduce the harm caused by lack of sleep, as well as the uncertainty of weekend sleep, you should develop the habit of regular and adequate sleep, even on weekends to observe the sleep schedule, go to bed early and get up early.
