Martin Ducret, doctor and journalist at Doctor’s Daily, returns today, on the occasion of the time change last night – we gained an hour of sleep with the change to winter time – based on some preconceived ideas about sleep.
franceinfo: First of all, is this time change bad for your health?
Martin Ducret: Yes, it can have harmful effects on health, but it is rather the transition from winter time to summer time – where we lose an hour of sleep – which is singled out in the literature. scientist.
Actually, the time change disrupts our internal biological clockwhat we call the circadian system, and this can lead to sleep and alertness disorders potentially responsible for accidents, but also mood disorders, or even cardiovascular problems.
Fortunately, the majority of people adapt to this change, without any health consequences. Little tip to synchronize yourself well, go to bed this evening, and this week, at your usual time, 11 p.m. for example, even if you are tired before.
Are the hours of sleep before midnight more restful?
“Well no, the hours before midnight don’t count double!” confirmed to me Dr Jérôme Pinot, sleep doctor and co-founder of centre Somnology in Paris. _”_In fact each of us has our own internal biological clock and our own bedtime.”
Some are early sleepers, they go to bed at 10 p.m. for example, and get up at dawn. Others are night owls, they go to bed after midnight, and will inevitably get up later. The most important thing is to sleep well between 7 and 8 hours per night.the number of hours needed for the majority of people to be in shape. We can therefore remember that the world does not belong to those who get up early but to those who get enough sleep.
But for short sleepers, is 5 to 6 hours of sleep enough?
Yes it’s true, but short sleepers are rare. Many people mistakenly think they are one of them, but in reality they do not get enough sleep due to many factors such as work, stress, screens or even children.
They thus accumulate a sleep debt, often during the week, which they try to compensate for on weekends and days off by sleeping longer. But this strategy has its limits. To be in good health, you must therefore respect your biological clock as much as possible by going to bed and getting up at a set time, as soon as possible.
To know exactly how many hours of sleep you need, take the test over 2 weeks of vacation. Generally, the first week you will sleep longer nights to compensate for your sleep debt. And it is during the second week that you will be able to know what your optimal biological clock is.
