Sit happens every year, almost without exception. The holidays are coming, work slows down, commitments change pace, and yet sleeping well becomes more difficult. You fall asleep late, you wake up in the middle of the night, the sleep seems lighter and less restorative. It’s not just the big dinners or the awkward schedules. From a psychological and neurobiological point of view, during the holidays the brain has a harder time “switching off”.
A more stimulated brain, not more relaxed
Although Christmas is associated with the idea of a break, for the brain it is often the opposite. Routines change, social, emotional and sensory stimuli increase. The nervous system remains in a state of prolonged activationknown as arousal.
Sleep neuropsychology studies show that difficulty falling asleep is often linked to excessive cognitive and emotional activation: crowded thoughts, memories, expectations, end-of-year balances. It is a form of “hyper-vigilance” that makes the natural transition to sleep more difficult.
Positive (but intense) emotions
It’s not just negative emotions that disturb rest. Even positive ones, if intense, can interfere with sleep. Anticipation, excitement, nostalgia, family meetings: all this increases the activity of the brain areas involved in emotional processing.
Sleep research shows that the brain needs predictability to relax. During the holidays, however, each day is different from the previous one. This continuous variability makes it more difficult for the biological clock to synchronize.
Hormones out of rhythm? Here’s what to do
Sleep is also regulated by a delicate hormonal balance. There melatoninthe hormone that signals the body that it’s time to sleep, is affected by light, meal times and evening activities. During the holidays, late dinners, prolonged artificial lights and late use of screens delay its release.
Studies published on Sleep Medicine Reviews show that exposure to light in the evening hours, especially that emitted by smartphones and televisions, can delay falling asleep and reduce the quality of sleepeven when you feel tired.
The burden of “having to feel good”
Then there is a more subtle, but very powerful aspect: emotional pressure. Christmas is full of social and personal expectations. You should be calm, present, grateful. When this doesn’t happen, the brain remains on alert.
Clinical psychology talks about stress from emotional inconsistency: the discomfort that arises when what we feel does not coincide with what we “should” feel. This state of mind is incompatible with the deep relaxation needed for sleep.
Is it insomnia? In most cases no
It is important to clarify this: in most cases it is not clinical insomniabut of a temporary response of the nervous system to a period full of stimuli. Holiday sleep is often more fragmented, but tends to normalize with the return of routines.
Research shows that the body has a remarkable ability to self-regulation: a few days of more stable schedules are enough for the sleep-wake rhythm to return to balance.
What really helps (without stiffness)
More than strict rules, small realistic precautions are needed:
- maintain a similar wake-up time each day
- reduce bright lights and screens in the hour before bed
- do not force sleep, but create favorable conditions
- accept that sleeping “a little less” for a few days is normal
The most important thing, from a psychological point of view, is Don’t turn sleep into a performance. The more you try to sleep, the more alert your brain remains.
Sleep less, but better with yourself
The sleep of the Holidays reminds us that the rest depends not only on the body, but also on the mind. In a period full of relationships, emotions and changesthe brain needs time to slow down. Accepting this transition, without judgment, is often the first step to getting back to sleeping better. This too, after all, is part of taking care of yourself.
