What happens to the brain during vacation

There is an almost universal scenario for the beginning of every vacation. On the first day, we promise not to look at the work chat. On the second one, we will still “just check” if there is anything urgent. On the third we already start to notice the sound of the waves, the aroma of the coffee or the coolness in the mountains. And somewhere between the first turned-off notification and the first truly deep sleep, something happens that we don’t see – our brains start to rewire themselves.

Although we often accept vacation as a reward or a luxury, neuroscientists and psychologists are increasingly defining it as a biological necessity. While we are simply “resting”, the brain performs a whole series of processes that can hardly happen in everyday life, filled with deadlines, notifications and constant switching between tasks.

One of the first things to change is your stress level. When we are under stress, the body releases more cortisol, the hormone that keeps us in a state of constant alertness. It’s helpful in the short term, but if it stays high for too long, it starts to affect our memory, concentration, and decision-making ability. This is why after extended periods without rest we often feel as if our brain is “foggy”. According to the Cleveland Clinic, even a few days away from the usual routine can reduce levels of stress hormones and improve our mood, concentration and ability to solve problems.

But the most interesting thing starts when we stop doing something all the time. While lying on the beach, walking through an unfamiliar city or simply looking out the window of the train, the brain is activated so-called Default Mode Network – a network of brain areas that works most intensively precisely when we are not focused on a specific task. Despite its misleading name, this is not an idle mode. On the contrary – then the brain organizes information, processes memories, connects ideas and looks for solutions to problems that we don’t even consciously think about. That is why so often the best ideas are born in the shower, during a walk or while looking at the sea.

The new environment also plays a huge role. In everyday life, the brain works economically – it uses the same routes, habits and patterns of behavior. On vacation, however, everything is different – new streets, a new language, different tastes, unfamiliar people. It is this novelty that activates the processes of neuroplasticity – the ability of the brain to build new connections between nerve cells. Therefore, after a trip we often feel fresher, more creative and even more open to new ideas. Medical professionals from the Pacific Neuroscience Institute note that travel stimulates areas of the brain associated with memory, spatial thinking, planning and learning, thus literally “training” the brain.

You’ve probably noticed another strange phenomenon – a week on vacation seems to last longer than a whole month at the office. This is not memory trickery, but the way the brain records experiences. When the days are similar, it creates less distinct memories and subsequently the period seems to “disappear”. When traveling, however, every day brings new impressions, more details and more emotions. As a result, the brain stores more “markers”, and we have the feeling that time has passed more slowly and we have experienced much more.

What’s even more surprising is that the positive changes start even before we’ve packed our bags. Just planning an upcoming vacation activates systems in the brain associated with reward anticipation. This boosts motivation and improves mood even weeks before the actual trip. Therefore, sometimes the feeling that “we have something good to come” is almost as refreshing as the vacation itself.

However, there is a reason that the first few days of vacation often make us unable to truly relax. After months of work, the brain doesn’t switch at the push of a button. It continues to await new tasks, messages and decisions. According to psychologists, this is exactly why many people feel anxiety during the first day or two – the nervous system needs time to come out of the mode of constant vigilance. Only then do the real recovery processes begin.

The bad news is that the effect doesn’t last forever. If we come home late at night and have dozens of emails, meetings and phone calls waiting for us the next morning, the brain quickly reverts to its old mode. That is why experts recommend that, whenever possible, there should be at least one day between the end of the vacation and the first day of work for smooth adaptation to everyday life.

Perhaps the best part of this whole story is that science frees us from guilt. If we’ve spent the afternoon in a hammock, watched the sunset doing nothing, or gotten lost in the streets of an unfamiliar city, we haven’t “wasted time.” On the contrary, we are giving our brain exactly what it needs to be more focused, more creative and more resilient when it returns to its daily challenges. Sometimes the most productive thing that we can do is simply allow ourselves to rest.
