Not getting enough sleep? It’s your lucky day. It would seem that the sacrosanct eight-hour night would not be as essential as previously imagined.
Because, according to a recent study, the time at which we fall asleep matters more than the number of hours, particularly when analyzing the long-term impact of sleep on health and longevity. This study published in the journal Sleepanalyzed data on the sleep of more than 60,000 sleepers, and showed that regularity in sleep schedules was correlated with a lower risk of death.

Respondents with a regular sleep schedule – going to bed and getting up at similar times each day – thus reduced the risk of premature death by 20 to 48%, cancer-related deaths by 16 to 39%, and heart problems or metabolic rates from 22 to 57%.
This does not mean that the rest is of no importance, far from it. However, the study shows that sleep duration is only one factor in the impact of sleep on general health.
“As I tell my patients, sleep schedules, and more particularly their consistency, are as important as the number of hours,” explains Jade Wu psychologist and sleep expert. “Everyone is obsessed with getting eight hours of sleep, but if we keep shifting those eight hours, we won’t get the benefits of a good night’s sleep. »
Jade Wu also notes that while needs may vary in number of hours, consistency is essential for everyone.
“We call it “social jet lag”: when you wake up at different times all week,” continues Jade Wu, giving the example of waking up at 6 a.m. on weekdays and 9 a.m. on weekends. end. “It’s like changing time zones every week”
And this has harmful consequences on health.
“It’s not only bad for your sleep,” continues the specialist, “but also for your metabolism, your metabolic, cognitive and cardiac health. So even if you exercise, eat well and get eight hours of sleep, you won’t reap these benefits if your sleep habits are not consistent.
“Our sleep likes nothing more than regularity, and the predictability of events which tells our brain to slow down the pace to prepare for the night is one of them” explains to us Alex Dimitriu, psychiatrist specializing in sleep in California. “For our sleep, nothing beats a regular routine of getting up and going to bed. Try not to sleep too much on weekends. Ideally no more than an additional hour than during the week. »
To keep your resolutions, you should opt for a ritual associated with sleep.
“Dim the lights, adopt a relaxing atmosphere, perhaps drink a little herbal tea: all these actions help to slow down the pace in preparation for the night. Sleep masks or meditation can also help you fall asleep.”
