Back-to-work stress after holiday:
why the anxiety shows up and what to do about it
Feeling stressed about going back to the office after a holiday does not mean you picked the wrong job, or that you did not rest enough. In a study of 96 employees, everything they had gained on holiday (energy, mood, relaxation) had already vanished in the first week back at work. The effect fades on its own, by design. The useful question is not how to keep it, but what to do on the days when your body is still protesting.
It is not a syndrome,
it is a transition with a medical-sounding name
Every August and September, the Romanian press runs the same articles about “post-holiday syndrome”. The phrase caught on because it sounds serious. The problem is that it does not describe one thing but three, which happen in parallel and call for different responses.
The first is a change of schedule. On holiday you go to bed and wake up later, and your internal clock shifts along with you. The second is a change in demand: after two weeks of making ten decisions a day, you return to a morning in which you make a hundred. The third, the one nobody writes about, is anticipation: the unease that turns up a day or two before you go back, while you are still on holiday and absolutely nothing has happened.
Mixed together, the three feel like a single vague state with no way out. Separated, two of them have fairly ordinary solutions, and the third is telling you something worth listening to.
It is not a diagnosis someone gives you after checking a list of criteria. It is a convenient label stuck on top of three different mechanisms. If you do not pull them apart, you end up treating a shifted schedule with breathing techniques, and a real problem at work with an earlier alarm.
What was actually measured:
96 people, one holiday, one week
The most cited study on this subject has a title that says it all: Lots of fun, quickly gone. Jessica de Bloom and her colleagues followed 96 employees before, during and after their holiday, publishing the results in the journal Work & Stress in 2010.
During the holiday, people did better on five measures: perceived health, mood, tension, energy levels and satisfaction. No surprise so far. The interesting part is what happened afterwards. In the first week back at work, the scores had generally returned to their pre-holiday levels.
Not in the second month. Not after a quarter. In the first week.
The practical conclusion is not that holidays are pointless. It is that a holiday is not a battery you charge for a whole year. It is a break, with a real effect while it lasts and for a little while after. If you expect the good mood to last until Christmas and it disappears in five days, you will think something is wrong with you. In fact you have an effect that behaves exactly as it did for the other 96 people.
Most of the suffering on your return comes from interpretation, not sensation. The sensation is common and temporary. The interpretation, “if I feel like this, something must be seriously wrong with me or with my job”, is what turns five uncomfortable days into three bad weeks.
The anxiety before
is not the same as the tiredness after
This is the distinction the usual articles miss. They lump everything together under “feeling bad after a holiday”. But the two states show up at different times, feel different and call for different things.
The unease before shows up in the last days of the holiday, sometimes on the very last evening. You are not tired yet, nobody has called you, nothing has happened. Your mind runs scenarios about what lies ahead, and your body reacts to scenarios as if they were events. The tiredness after shows up in the first days back at work and is more physical: you struggle to get up, your head feels heavy at 3 pm, and you fall asleep later than you would like.
The first column is solved with paper. The second with light, regular hours and a little patience, and we have written about it at length in the guide on getting back to your sleep schedule after a holiday. The third is not about the holiday at all.
Unease with an object
and unease without one
There is a simple test you can do in two minutes with a pen. Write down exactly what is making you uneasy about going back. Not in general, but specifically: the project that stalled, the conversation you keep putting off, the figure that was due on Friday.
Your unease has an object. It feels unpleasant, but it is really an inventory problem: your mind is keeping five unfinished things open and running through them one by one, because it has nowhere to put them. Once written down, they become tasks. Tasks can be scheduled.
Your unease has no object: a vague discomfort tied to the idea of going back, not to any particular task. Here an inventory does not help, because there is nothing to list. It deserves to be taken seriously as information, not as a character flaw.
The second case does not automatically mean you should hand in your notice. It may come from accumulated exhaustion, a tense relationship at work, or a period in which you said yes too often. But it does mean the answer is not a better list, nor a stricter morning routine.
When it is worth talking to someone qualified: if the feeling no longer has anything to do with the holiday and has lasted more than two weeks, if it affects your sleep, appetite or ability to function at work, if you have panic attacks, or if you feel hopeless. A psychologist or your GP is the place to start, and this is a health conversation, not one about supplements. A blog article, however well researched, cannot do this triage for you.
The evening before:
two things that have been measured
The usual advice for the last evening of a holiday is “relax” and “don’t think about work”. Both ask for exactly the thing your mind refuses to do. There are, however, two small interventions that someone has actually tested.
Write tomorrow’s list, not yesterday’s diary
Michael Scullin and his colleagues had 57 participants write for five minutes before bed in a sleep laboratory, with polysomnographic recording. Some wrote down what they had to do over the next few days, the others wrote down what they had already finished. Those who wrote the to-do list fell asleep faster. The study was published in the Journal of Experimental Psychology: General in 2018.
It is a small study, on students, in a laboratory. It is not a law of nature. But the direction is useful and it costs five minutes: the mind seems to settle more easily when unfinished tasks are put on paper instead of being kept open.
Make your plan in if-then form
“Tomorrow I’ll get organised” is an intention. “If I open my email at 9:15, then I’ll read only what came in over the last three days and leave the rest for Thursday” is a plan. The difference has a name in psychology, implementation intentions, and it also has a size: the 2006 meta-analysis by Peter Gollwitzer and Paschal Sheeran reports an effect of 0.65 on goal attainment, across 94 independent tests.
An effect of that size is large for an intervention that amounts to writing one sentence. All the magic lies in fixing the moment and the place, not just the intention.
Your first day back,
hour by hour
This is not a mandatory schedule and it will not suit every job. It is a structure that solves one specific problem: the first day usually disappears into reading emails and feeling guilty, and by the evening you feel as if you have done nothing, even though you were tired the whole time.
| Time | What you do | Why |
|---|---|---|
| Before you leave | 15 minutes outdoors, in natural light | Morning light is the strongest cue for your internal clock. Coffee on the balcony counts. |
| The first hour | Do not open your email. Write down on paper the three things that matter today. | Your inbox is someone else’s list of priorities. If you go into it first thing, your day is written by other people. |
| The second hour | The most important of those three tasks, with your phone in another corner of the room | Your concentration is at its best now, and on the first day it drops quickly. |
| Towards lunchtime | Email, once, with a rule you set beforehand | You have already got something done. The inbox becomes a task, not an avalanche. |
| The afternoon | Mechanical things: admin, tidying up, planning the week | It is the stretch in which you would not make good decisions anyway. Do not fight it. |
| End of the day | Five minutes on tomorrow’s list, then close the laptop | The same move as last night, for the same reason: tasks on paper, not in your head. |
Do not schedule big decisions on the first day. No resignations, no pay discussions, no reorganisations. You are on a shifted clock, on a day of sudden demand, and your brain reads everything as darker than it is. Four days from now the same things will look different.
Sleep,
the part you really can correct
Of the three mechanisms, the shifted schedule is the only one that behaves predictably. Your internal clock moves with light, not with willpower, and on holiday it shifted towards the evening because you went to bed later and saw the morning light later.
What works, in short: daylight outdoors as soon as possible after waking, getting up at the same time including at weekends, and moving your bedtime gradually, by 15 to 30 minutes a day, not by two hours at once. The details, including the difference between sleep debt and a phase shift, are in the guide to getting back to your sleep schedule. If it feels more like tiredness that will not go away, it is also worth reading why you are tired even though you sleep eight hours, and if it is a foggy head, what brain fog is really about.
As for melatonin, the only thing we are allowed to say, because it is the only claim authorised in the European Union, is that melatonin contributes to the reduction of time taken to fall asleep. The claim may be used for an intake of at least 1 mg, taken close to bedtime. That is all. Nowhere does it say that it calms you, reduces stress or makes tomorrow easier. We have explained how to use it, and when it makes no sense, in the guide to melatonin.
Melatonin is not for everyone, and not for every occasion. Do not take it during pregnancy or breastfeeding, do not give it to children and teenagers without a doctor’s advice, and do not combine it with sedatives, anticoagulants, antidepressants or blood pressure medication without first asking your doctor or pharmacist. Do not drive or operate machinery after taking it. If you are on any long-term treatment, ask before, not after.
The figures doing the rounds
and where they do not come from
When we read what has been written in Romanian on this subject, we came across the same figures repeated from article to article, with no source. We looked each one up. Here is what we found, and what we did not.
The figure appears in several Romanian articles, always without a named study. We could not trace any research that backs it up. That does not automatically make it false; it means that none of the people publishing it say where it comes from. A figure with no source is not information, it is decoration.
The range is so wide that it covers anything. What can be said with a measurement behind it is something else, and it comes from the de Bloom study: the boost in wellbeing from the holiday had returned to its earlier levels in the first week back at work. It is a more modest claim, and a more useful one.
In the articles where it appears, nobody measured anything. It is an explanation that sounds plausible and gives you the feeling of understanding the mechanism. What is really known about stress hormones is less spectacular and much slower than a change from one day to the next.
The discomfort of the first few days also shows up in people who like their work, because it comes from a change in schedule and demand, not from an assessment of their career. The signal worth listening to is a different one: a feeling that is not tied to sleep, does not ease after two weeks and is steadier than tiredness.
For a shifted schedule, yes, your wake-up time and morning light really are the main lever. For unease without an object, a stricter routine just adds one more thing you can feel you have failed at. Not every state is solved with discipline.
What a supplement can
and cannot do here
Among other things, we sell a bundle designed for exactly this period: the Zero Stress & Calm Sleep Bundle, which is KSM-66 ashwagandha and melatonin gummies. Since this whole article has been about figures with a source, it would be odd to end with a promise without one.
Ashwagandha has no authorised health claim in the European Union. None. We cannot tell you that it reduces stress, lowers cortisol or calms you down, because we are not allowed to, and because that is not where the evidence stands. What we can tell you is what it is: a plant used for centuries in Ayurvedic medicine, which we offer as the KSM-66 extract, with the dose written on the box. We have put everything that can accurately be said about it in the guide to when to take ashwagandha, including why the form of the extract matters more than the promises on the box.
Melatonin has a single authorised claim, the one about the time taken to fall asleep, at a minimum of 1 mg. The dose on our label is 5 mg. Half of it, 2.5 mg, is already two and a half times the threshold for the claim, so starting with half a serving is a sensible choice, not a timid one. More does not automatically mean better.
What this bundle does not do: it does not treat anxiety, it is not an anxiolytic and it does not replace a conversation with a psychologist or your doctor. It will not empty your inbox, and it will not change the real cause if your unease has no object. If you have come back from a holiday and something at work is no longer working, no gummy is the answer, and we would rather write that than sell you something else.
