Com the entry of a new week, also arrives a new time: the clocks will change already in the early morning of sunday, october 25, and will “win” an hour.
The current regime for changing the time is regulated by a directive (Community law) of 2000, which provides that each year the clocks are, respectively, advanced and delayed one hour on the last Sunday of March and last Sunday of October, marking the beginning and end of summer time.
When's it gonna happen?
In continental Portugal and Madeira the change of time occurs when it is 2:00 a.m. Sunday morning, October 25. At this point, you'll have to delay the clock to 1:00.
In the Azores, due to the hourly difference (less than one hour on the continent) the change takes place at 1 a.m. In this archipelago, the hands pass again to midnight.
Remember that the next change of hour will be on the last Sunday of March – the 28th – and that we will return to summer time.
Between care and tips, what should you know?
Note that with this change it will start to be dark early and it is important that you start making some changes to your routine so that you do not feel the effects particularly.
Zoe Williams, a family doctor and sleep specialist at Dreams to the Tom’s Guide website, explains that change can bring consequences and that one of the changes in sleep that eventually happen is to feel tired at a time of the day when this did not happen. “After changing hours, some people may feel tired earlier at night, wake up early in the morning or even have a drop in energy or concentration while the body adjusts,” says expert.
Zoe Williams also recalls that this extra hour of sleep should be harnessed in the best way: “If you don’t sleep enough regularly, changing hours may be a good opportunity to spend a little more time in bed. This is if you do not use that extra time automatically to stay up until later.”
Adaptation may take longer for some people, and some people may still have a strange feeling that something is not right. “When clocks are delayed, early at night may cause your body to start producing melatonin, potentially making you sleep earlier than normal. This change can make you feel unsynchronized as your body adjusts to the new schedule,” said Opera Beds expert Tim Mercer.
For some people the change will be easier. Why?
Psychologist Mafalda Navarro spoke to Lifestyle to Minute on the subject and explained that for some people the adaptation may be more difficult, and that in question are age, quality of previous sleep or individual sensitivity. The expert also says that many people adapt in a few days, but others, the “process may take about a week or, sometimes more, depending on the chronotype, exposure to light, regularity of hours and quality of sleep before change”.
In children, some changes can also be seen, with parents and educators being able to observe “greater irritability in the child, increased episodes of crying, opposition or difficulty in accepting limits, especially when waking up, at the end of the day or when she is tired”.
“ Changes in attention, some drowsiness or, in the opposite way, greater agitation may also occur, with difficulty in regulating behavior. It is common for parents to report resistance at bedtime, because the child does not feel enough sleep pressure to be able to fall asleep ", alert. The psychologist has left some advice to adapt better.
